Flat steel is a kind of common metal material, its section shape is rectangular, the width is greater than the height. Flat Steel has excellent mechanical properties and processing properties, widely used in construction, machinery manufacturing, automotive manufacturing and other fields. In this paper, the material properties, processing technology and application fields of flat steel are studied.
一、Material Properties of flat steel
The material properties of flat steel mainly include mechanical properties, physical properties and chemical properties. Mechanical properties are the performance of flat steel under stress, including tensile strength, yield strength, elongation and so on. Physical properties refer to the Coefficient of thermal expansion, thermal conductivity and electrical conductivity of flat steel. Chemical properties refer to the chemical composition and corrosion resistance of flat steel.
The flat steel has excellent mechanical properties, high tensile strength, high yield strength and high elongation. Flat steel also has good physical properties, small Coefficient of thermal expansion, high thermal conductivity and high electrical conductivity. The chemical composition of flat steel is mainly carbon, silicon, manganese, phosphorus, sulfur and other elements, corrosion resistance is good.
二、Processing Technology of flat steel
The production process of flat steel usually includes the following steps:
1.Material Selection: select the production requirements of the raw materials for processing, usually the choice of hot or cold-rolled plate.
2.Processing molding: the raw materials are processed into the initial shape of flat steel by shearing, cutting, beveling and curling.
3.Steel Pretreatment: the finished steel surface rust removal, polishing, painting and other treatment to improve the surface quality and service life.
4.Hot or cold rolling: rolling steel at high or normal temperatures to form the desired thickness and width, while also improving the physical properties of the steel.
5.Straightening and leveling: the rolled steel needs to be straightened and leveled, in this process need to use professional equipment for stretching, leveling and other operations, in order to eliminate the steel rolling stress and defects.
6.Shear cutting: according to different needs, hot or cold-rolled flat steel according to the standard size of cutting, you can use mechanical cutting or manual cutting methods.
7.Inspection Packing: packing flat steel that has been processed and tested to be up to standard for ease of transport and use. Various tests and quality checks are required to ensure that the flat steel meets the standards and requirements.
三、Application area
1.Children’s products: Children’s Ball pool, children’s football net, children’s tent, children’s mosquito net
2.Household items: laundry drying basket, festival supplies, Dirty Laundry Basket
3.Outdoor supplies: camping tents, disaster relief tents, electric car awning, beach tents
4.Promotional Items: A-screen billboard, studio reflector
