Hot rolling uses slabs (mainly continuous cast slabs) as raw materials, which are heated and then made into strips by rough rolling units and finishing rolling units. The hot steel strip coming out of the last rolling mill of finishing rolling is cooled to the set temperature by laminar flow and rolled into steel strip coils by the coiler. The cooled steel strip coils go through different finishing lines (flattening, Straightening, cross-cutting or slitting, inspection, weighing, packaging and marking, etc.) are processed into steel plates, flat coils and slit steel strip products. To put it simply, after a piece of steel billet is heated (it is the red-hot steel block on TV), it is rolled several times and then trimmed and straightened into a steel plate. This is called hot rolling.
Cold rolling: hot-rolled steel coils are used as raw materials, pickled to remove scale, and then cold-rolled continuously. The finished product is hard-rolled coils. Due to cold work hardening caused by continuous cold deformation, the strength and hardness of hard-rolled coils increase. The toughness and plasticity index will decrease, so the stamping performance will deteriorate and it can only be used for parts with simple deformation. Hard rolled coils can be used as raw materials in hot-dip galvanizing plants because hot-dip galvanizing units are equipped with annealing lines. The weight of hard-rolled coils is generally ~.3 tons. The hot-rolled pickled coils are continuously rolled at room temperature. The inner diameter is.
Product features: Because it has a very high hardness (RB is greater than RB) without annealing treatment, the machining performance is extremely poor and it can only perform simple directional bending of less than 10 degrees (perpendicular to the coiling direction).
To put it simply, cold rolling is processed and rolled on the basis of hot rolled coils. Generally speaking, it is a process of hot rolling-pickling-cold rolling. Cold rolling is processed from hot-rolled plates at room temperature. Although rolling will also heat up the steel plate during the processing, it is still called cold rolling. Because hot rolling undergoes continuous cold deformation, cold rolling has poor mechanical properties and has too high hardness. It must be annealed to restore its mechanical properties. Those without annealing are called hard rolled coils. Hard rolled coils are generally used to make products that do not require bending or stretching.
Cold-rolled plates and strips are widely used in automobile manufacturing, electrical products, rolling stock, aviation, precision instruments, food cans, etc. Cold-rolled thin steel plate is the abbreviation of ordinary carbon structural steel cold-rolled plate. It is also called cold-rolled plate, commonly known as cold plate, and is sometimes mistakenly written as cold-rolled plate. Cold plates are made from ordinary carbon structural steel hot-rolled steel strips that are further cold-rolled into steel plates with a thickness less than 10%. Since rolling at room temperature does not produce scale, the cold plate has good surface quality and high dimensional accuracy. Coupled with the annealing treatment, its mechanical and process properties are better than those of hot-rolled thin steel plates. It has been gradually replaced by it in many fields, especially in the field of home appliance manufacturing. Hot rolled steel plate.
The surface of a steel plate electroplated with a layer of about 1 mm of metallic zinc has an anti-corrosion effect and is widely used in the construction industry. This zinc-coated thin steel plate is called a galvanized plate. Galvanizing is an economical and effective anti-corrosion method that is often used. About half of the world's zinc production is used in this process.
