Cold rolled coil is made of hot rolled coil as raw material and cold rolled with I hardening, but it is generally believed that it is cold rolled with cold rolled raw material at room temperature. In European and American countries, 3~6 consecutive extruders are the key.
As a cold rolling machine, it includes thick steel plates and waterproof coiled materials. Ansteel, WISCO, Shougang and many other steel mills in China can produce such goods. Among them, the delivered goods are called thick steel plates
It is called a boxboard or tablet computer. Long cold-rolled nylon strip is also called cold-rolled thick steel plate.
Hot rolled coil is made of square billet (mainly rolled steel square billet). After heating, the hot rolled strip steel is made into fine extruders by rough extruders and fine extruders. The hot nylon strip is cooled to the set temperature according to the laminar flow, and cold rolled into steel coils according to the coiler. The nylon strip coil after refrigeration is produced and processed into thick steel plate, flat roll and vertical laser cut nylon strip according to different casting and rolling lines (leveling, straightening, horizontal laser cutting or vertical laser cutting, detection, weighing, packaging and identification, etc.) According to the customer’s specifications, hot rolled steel products are widely used in the steel production and manufacturing fields such as ships, cars, highway bridges, engineering buildings, mechanical equipment and high-pressure vessels due to their high compressive strength, good ductility, ease of production and processing, and good weldability of electric welding.
With the improvement of new control systems such as the precision of hot rolled coil specifications, shape and process performance, and the emergence of new products, the products of hot rolled thick steel plate and hot rolled strip have been more and more widely used
The competitiveness in the sales market is becoming stronger and stronger.
Hot rolled stainless steel plate includes nylon belt (roll) and thick steel plate (roll) cut by laser from steel. According to the raw materials and characteristics, hot rolled stainless steel plate can be divided into straight roll and thin roll (dividing roll, flat roll
And vertical laser cutting roll).
Hot continuous rolling can be divided into ordinary carbon steel, high alloy steel and carbon steel
It can be divided into cold drawn section steel, alloy structural steel, car alloy structural steel, corrosion resistant alloy structural steel, mechanical equipment alloy structural steel, electric welding tank and high pressure vessel steel, pipeline steel, etc. Based on different
situation,
Hot rolled steel products have universal specifications, models and applications, and are widely used to produce and manufacture cars, roads and bridges, ships, heating furnaces and high-pressure vessels from general engineering project structures. Main use of non sample
There are different regulations on raw material properties, process performance, specifications and appearance precision of thick steel plates. Therefore, it is necessary to master the types, raw materials, characteristics and main uses of hot rolled steel to facilitate economic development
Local application.
