Three Kinds Of Technology For Steel Structure Cutting

There are three kinds of technology for steel structure cutting. They are plasma arc cutting, water jet cutting and flame cutting. Plasma arc cutting makes the incision of the metal workpiece melting partially by using heat of plasma arc which is with high temperature. And this cutting method is exclusion of molten metal with the help of the plasma momentum.

Water jet cutting is a new technology in recent years. This technology use high pressure to rushed out the water column to cut steel plate. This technology is advanced and cutting precision is high. It is fit for cutting the steel plate which needs high precious, thickness with medium or thin.

At present, flame cutting is a cutting technology which is the most widely used. It mainly uses gas mixed with oxygen combustion to produce high temperature to make steel melt and oxidation. So that people can reach the goal of cutting. The gas that we often used include natural gas, acetylene, propane and so on. Acetylene has been explicitly eliminated by the state. Natural gas, propane are new type of gas, they all need to add catalyst.

Get Knowledge Of Steel Corrosion

Steel corrosion not only make the sectional area decreased, but also reduce its performance and even scrapped. Besides if it has been appeared corrosion pit, that will make stress concentration and accelerate structural damage. Especially impact load and cyclic alternating loads, it will appear phenomenon of corrosion fatigue. At this time, the fatigue strength of the steel will be reduced greatly, and even the emergence of brittle fracture.

According to the corrosion mechanism, steel corrosion can be divided into two kinds, they are chemical corrosion and electrochemical corrosion. Chemical corrosion is means that steel reaction with surrounding medium directly, and then producing corrosion. These corrosion are mostly caused by oxidation, steel surface will form loose oxide. Electrochemical corrosion is always caused of the steel contact with electrolyte solution. They form micro battery and caused corrosion finally.

There are many factors that lead to steel corrosion. They mainly include humidity and oxygen in environment, acid, alkali, salt in the medium, steel surface condition and its chemical composition. Some halogen ions, especial chloride ion can damage protective film and improve the reaction of corrosion. So the corrosion may be developed quickly.

Advantages Of Steel Structure

Compared to other structure, steel structure has its own advantages in designing, use and comprehensive economic. It is usually in low cost and can be moved at any time. Steel structure residence is better than traditional buildings because it can meet flexible separation requirements.

We could improve the area utilization ratio by reducing the cross-sectional area of the column and using lightweight wall panels. Effective use of indoor area will be increased about 6%. Steel structure has good energy saving effect, thermal insulation performance and good seismic reliability. The wall adopts C type steel and sandwich panel with light energy saving standard.

Steel structural system will be used for residential buildings. That could give full play to ductility of steel structure. At the same time, that will own strong plastic deformation ability, excellent properties of anti seismic and wind resistance. It has been improved the safety and reliability of residential greatly. Especially in the earthquake, typhoon disaster situation. Steel structure is always in quick construction speed. The time limit for a project is shorter than tradition residential system. What’s more, steel structure has good environmental protection effect. Steel structure residence reduces the sand, stone and ash dosage greatly in construction.

Descaling Method For Steel Structure

As we all known, steel structure material is not easy to be rust, it is fatal if the steel structure rust. It may lead to seriously consequence. There are many descaling method for steel structures. Such as manual descaling, sand or shot blasting, acid pickling and others.

Manual descaling is always in low efficiency and can not derusting throughly. It has an influence on the adhesion of the paint and the structure is easy to rust. Some light steel structures with small round bar and angle steel mostly adopt this descaling method. When you use the acid pickling, you should put the component into a pickling tank and remove the oil and rust at first. Keep its surface in gray iron and clean it clear after acid pickling.

Some people like to use sandblasting and shot peening to remove the rust. Make its surface clean up by sandblasting machine. Them it will exposed metal color. This descaling method can do more thoroughly than other method. At the same time, this method is in high efficiency. But the best method to move the rust is pickling phosphating.

Light Steel Structure Engineering

At present, light steel structure is developed quickly in China. Compared to the traditional reinforced concrete structure and ordinary steel structure, light steel structure has many advantages. Light weight is the significant features of light steel structure. Light steel structure is also in high degree of industrialization. Components of cold-formed steel, pressure plate, connecting pieces are automation. So it is always in high efficiency and good quality.

As we all known, light steel structure is in favor of environmental protection. This structure is belong to environmental protection and energy-saving materials. Workshop can be moved, materials can be recycled. Light steel construction in low level mainly use the solid web type or latticed frame structure system. Now there are industrial building, hangar, waiting room, terminal building, supermarkets, farmers market, catering and entertainment room, sports facilities and other light steel structure with low level in China.

Application scope of light steel structure is not limited to the house which is in small span, but it has been replaced part of ordinary steel structure. With the development of light steel structure, it can not only save the steel consumption, but also with strong seismic capacity. Certainly it also improve the comprehensive seismic performance of the whole house.

Steel Structure Build Green And Low Carbon Building

Recent years, steel structure rise quickly as a green cycle and low carbon building in China. Some expert point that this will make a large market to steel structure. At the same time, it will put forward new and higher requirements to steel supplier.

At present, there is little species and bad quality stability in China. Many steel structure manufacture pay little attention on steel supplying. So they should find new varieties of steel in order to meet the requirement of steel market.

Carbon emissions of the traditional construction account for almost 50% in total carbon emissions. This proportion is far higher than the transport and industry. In Europe, Australia and Japan, the local construction industry is very concerned about the carbon constraints and circular economy. Steel structure housing assembly has developed to a very perfect stage. And it has been account upon 40% of total residential building. This assembly type steel structure can saving resources, reduce pollution, protect environment. And it also offer a healthy, suitable and efficient using space. Steel structure residential or building will broke boundary line of real estate, construction, machinery and equipment manufacturing, new building materials, green construction, disaster prevention and mitigation, kitchen appliances decoration industries.

Steel Structure Instability And Corrosion

The important structures which are easy to occur load change adopt hyperstatic structure, such as bridge, truss, sluice gate and missile launchers. Because they have redundant bar which can prevent that a member instability cause the overall instability.

Steel structure instability can be divided into two categories. They are overall buckling and local buckling. The overall instability mostly caused by partial instability. When the compression part or bending parts of the slenderness ratio exceeds the allowable value, it will lose stability. Many objective factors will have effect on it, such as loading changes, initial defect of steel and different support. The support is often neglected by designers and constructors. It is also one reason to cause overall instability. Truss or bar stress may change, and even resulting in instability because of different hanging position. Scaffolding collapse, collapse or deformation are mostly caused by no support or link deficiency.

If instability is acute disease, corrosion will be a chronic disease. Anti corrosion performance of ordinary steel is bad, especially for staying in the environment which has high humidity and corrosive medium. Because it usually will be rust and corrosion quickly.

Reinforcement Technology Of Steel Structure Damage

If there are some damages in steel structure, we need solve problem in time. There are five factors that caused steel structure damage. Firstly, the load changed, the service extended, rules and regulations changed. Secondly, structure deformation,twist,disability or depression with various accidents. And it also section weaken, rod warping, connection cracking. Thirdly, component or connection deformation, cracking and warping which caused by temperature effects. Chemical corrosion make the section of steel structure weaken. Certainly, other illegal use and operation will lead to damage.

There are three reinforcement method to steel structure. They are section reinforcement, change the calculation diagram and prestressed cable method. Section reinforcement is using the steel to reinforcement in local or along the member length. The method of changing calculation diagram is that adding support, adjust load distribution,reduce stress levels, decrease the stress peak. Prestressed cable method is that strengthening weak links with high-strength cable or improving the whole structure bearing capacity, rigidity and stability.

Once the earthquake occurred, we must first maintain a clear, cool headed and determine shock condition promptly. Don’t jump off building in panic. This is very important. Besides you can hidden under solid furniture or corner. Certainly you can also transferred to the kitchen which has small hall and many load-bearing walls or even toilet. Because these places has strong combining power, especially the pipe has good support force after some treatment, and seismic coefficient is larger.
