One of the four major varieties of steel (plate, pipe, profile and wire). According to the section shape, the section steel is divided into simple section steel and complex section steel (section steel). The former refers to square steel, round steel, flat steel, angle steel, hexagonal steel, etc; The latter refers to I-beam, channel steel, rail, window frame steel, bending section steel, etc.
The working principle of pre leveling and pre leveling the thickness of the flat steel in the upper and lower cold direction of the whole machine is the process of pre leveling the flat steel in the upper and lower cold direction;
A pair of finishing wheels arranged relatively are used to extrude the width direction, so that the width is compressed to achieve the expected parameters, and the compression amount is adjustable;
Straighten the width with 5 staggered straightening wheels. The system is mainly composed of control box, finishing roller, pre leveling unit, finishing unit and straightening unit.
What does galvanized flat steel mean?
"-" is the code of flat steel, 40 is the width of section steel, 4 is the thickness of section steel, and the unit is mm.
Flat steel refers to steel with a width of 12 -, a thickness of 4 -, a rectangular section and a slightly blunt edge. Flat steel can be finished steel, or it can be used as blank for welded pipe and thin slab for laminated thin plate. Main uses: as a finished material, flat steel can be used to make hoop iron, tools and mechanical parts, and used as building frame structural parts and escalators in buildings.
Advantages of flat iron products:
1. Flat steel is rolled with negative deviation, but delivered according to the actual weight, and the utilization rate is 1 ~ 5 percentage points higher than that of steel plate.
2. Flat steel can be produced with fixed thickness, width and length according to the needs of users, which reduces cutting, saves processes, reduces the consumption of labor and materials, reduces the processing loss of raw materials, and saves time, labor and materials. The products have been used in steel structure manufacturing, machinery manufacturing, automobile industry, mining machinery, hoisting machinery and other industries.
