Application of stainless steel coil plate in several major industries

From the analysis of stainless steel coil application industry, the automotive industry is currently the fastest developing stainless steel coil application field.In the past decade, consumption of stainless steel coil plates for cars has risen from an average of 10kg to 30kg in Japan and more than 40kg in the US.Bus, subway, high-speed railway vehicles and other public transportation tools are also widely used in stainless steel coil plate.China's home appliance industry is a potential large market for the application of stainless steel coil.In addition, stainless steel coil in the water industry, construction and structural industry, environmental protection industry, industrial facilities demand will also increase year by year.

The vehicle/automobile industry

This is currently the fastest growing stainless steel coil application area.Using high strength stainless steel coil plate to manufacture the car body structure can greatly reduce the dead weight of the vehicle and enhance the strength of the car body structure. Using stainless steel coil plate as the panel and decorative parts of the vehicle can reduce the maintenance cost.In addition, stainless steel coil has the advantages of resistance to chloride ion corrosion and heat resistance and is used in automobile exhaust systems.Now, Japan, the United States, Sweden and other countries have been a large number of stainless steel rolling plate vehicles.Japan began to promote from the 80's, its stainless steel rolling plate train vehicle has reached 60%.The car industry is the focus of the development of stainless steel coil application.

Water industry

The pollution of water during its storage and transportation has been paid more and more attention.A lot of practice has proved that stainless steel coil is the best material for water industry such as water preparation, storage, transportation, purification, regeneration and desalination.Its advantages are: corrosion resistance, earthquake resistance, water saving, sanitation (no rust and copper green), light weight (reduce 1/3), less maintenance, long life (can be used for 40 years), low life cycle cost (LCC), is a recyclable green environmental protection material.According to introduction, at present, stainless steel of pipe of Tokyo area of Japan coils plate to already amounted to 76%, pipe leakage rate drops to 7.5% at present by original 14.7%.Stainless steel coil water storage tank intact after earthquake in Osaka, Japan.Recently, Japan developed the bellows joint, which reduced the construction cost of the stainless steel coil water pipeline by 20%, the total cost by 3%, and the maintenance cost by 3/4.

The construction industry

It is one of the earliest applications of stainless steel coil.In terms of architectural decoration, at present, stainless steel coil is mainly used in the outer wall of high-rise buildings, indoor and external column cladding, handrails, floors, elevator siding, doors and Windows, curtain walls and other internal and external decoration and components.After the surface treatment, coloring, coating of the stainless steel coil plate, to solve the touch after the easy to appear fingerprints and other problems, so that the application of stainless steel coil plate is further expanded.Japan has developed a variety of stainless steel roofing materials, such as high and medium chromium ferritic with better corrosion resistance and a variety of coated plates.Super-Clean brushed stainless steel coil panels developed in Sweden and UGITop surface panels developed by UGINE in France offer new options for the construction industry.

industry

In home appliance business, stainless steel rolls plate dosage big is lining of inner cylinder of automatic washing machine, inner liner of water heater, shell of inside and outside microwave oven, refrigerator, and use ferrite stainless steel rolls plate more.The proportion of stainless steel of west European household electricity coils plate is larger, Asia is used commonly outside Japanese close to European level less.In 1999, the Japanese home appliance industry ferrite, martensite type stainless steel coil consumption reached 28%, austenite accounted for 12%.The microwave ovens, refrigerators, air conditioners and TV sets produced in China have become competitive export products in the world, and the domestic home appliance industry is a potential big market for the application of stainless steel coil.It is estimated that in the next 5-10 years, the demand for stainless steel coil plate in China's home appliance industry will reach 100,000-150,000 tons.

Environmental protection industry

Industrial waste gas, waste and sewage treatment units should be made of stainless steel coil.In the process of flue gas desulfurization, in order to resist the corrosion of sulfur dioxide and chloride ion, iron ion, in the absorption tower, cooler, pump, valve, flue and other areas need to use double-phase stainless steel coil and high grade austenitic stainless steel coil.Waste incinerator, waste water treatment and other facilities need to use high performance stainless steel coil material.

Industrial facilities

The proportion of stainless steel coil plate used in industrial facilities in developed countries can be generally reached 15%-20%, and the current domestic application proportion is still very small.On the one hand, due to the introduction of complete sets of industrial equipment, stainless steel coil material has not been counted, on the other hand, because the domestic material has not been used.Chemical, petrochemical, chemical fiber, paper, food, medicine, energy (nuclear power, thermal power, fuel cell) and other fields need stainless steel coil plate.In addition, the existing imported equipment has entered the maintenance period.With the improvement of the quality of domestic stainless steel coil products and the development of special brand products, the application of stainless steel coil in domestic industrial facilities will increase year by year.
