What are the Production Process and Process of Flat Steel?
Flat steel refers to 12-300mm wide, 3-60mm thick, rectangular section and slightly blunt edge steel. Flat steel can be finished steel, or it can be used as blank for welding pipes and thin slab for rolling sheet. Main uses: Flat steel as a material can be used to make hoop iron, tools and mechanical parts, and used as building frame structural parts and escalators.
Flat steel product specifications file spacing is dense, can meet the needs of users, instead of the use of the plate, without cutting, can be directly welded, the surface of the product clean. In the process, high-pressure water descaling process is used twice to ensure that the steel surface is smooth, the two sides are vertical, and the water corner is clear. Two vertical rolling in finishing rolling ensures good verticality, clear Angle and good surface quality of both sides.
The expression of flat steel is: B*t, “t” is the thickness, “B” is the width.
Characteristics of flat steel
1. Special product specifications. The thickness is 8 ~ 50mm, the width is 150-625mm, the length is 5-15m, and the product specification file distance is dense, which can meet the needs of users, and can be used instead of the middle plate, without cutting, and can be directly welded.
2. Smooth surface of the product. High-pressure water descaling process is used twice in the process to ensure smooth steel surface.
3. The two sides are vertical with clear edges. Two vertical rolling in finishing rolling ensures good verticality, clear Angle and good surface quality of both sides.
4. The scale of the product is accurate, the three-point difference, the level difference is better than the steel plate standard; The product is flat and straight, and the plate shape is good. Finishing rolling adopts continuous rolling process, automatic loop automatic control, to ensure that no stacking steel does not pull steel, product dimensional accuracy is high, tolerance range, three point difference, the same strip difference, sickle bend and other parameters are better than the plate, and the plate straightness is good. Cold cutting, high precision length measurement.
The use of flat steel
The main uses of flat steel: flat steel as a material can be used to make hoop iron, tools and mechanical parts, and used as structural parts of the building frame and escalators.
Hot rolled flat steel applications
1. Hot rolled flat steel can be used to make components, escalators, Bridges and fences.
Hot rolled flat steel has good strength, and the surface of hot rolled flat steel is relatively smooth compared with other steels. In addition, the thickness of the hot rolled flat steel is very tight, which determines that the hot rolled flat steel is very suitable for welding. It is worth mentioning that the bearing weight of flat steel is large. And components, escalators and fences and other items in the production process, welding is an essential processing technology. At the same time, such objects must also require the surface of the steel to be smooth and able to bear a certain amount of large weights. Some characteristics of flat steel exactly meet the requirements. This makes hot-rolled flat steel a raw material for processing components, escalators and fences.
2. Hot rolled flat steel can be used as welding steel billet and slab rolling sheet.
Hot rolled flat steel is a type of steel with a rectangular interface, which can be regarded as part of a long steel sheet. This allows the hot-rolled flat steel to be processed into a larger steel plate.
Advantages
1. Flat steel is rolled with negative deviation, but according to the actual weight delivery, the utilization rate is 1-5 percentage points higher than the steel plate.
2. Flat steel can be produced according to user needs, with fixed thickness, width and length.
It reduces cutting and saves processes for users, reducing the consumption of labor and materials. It also reduces the processing loss of raw materials, saving time, effort and materials. Products have been professionally used in steel structure manufacturing, machinery manufacturing, automobile industry, mining machinery, hoisting machinery and other industrial materials.
