Mild Carbon Steel Coil&Sheet / Hot Rolled Coil / SHANQI China Professional Manufacturer

Carbon Steel Coil is a type of plate, which is actually a thin steel plate that is long and narrow and supplied in coils. The main difference between Coiled plate and flat sheets lies in cutting and packaging.

Hot rolled steel undergoes a rolling process that involves forming and rolling steel slabs into long, hot bands while heated at extremely high temperatures (typically over 1,700'F) above steels recrystallization temperatures.

The hot rolled steel is malleable at high temperatures, enabling it to be rolled into various shapes, forms, and sizes. After forming, the steel is cooled at room temperature, typically leaving a scaly surface finish that techniques like pickling can remove.

Hot rolling uses slabs (mainly continuous slabs) as raw materials, and after heating, strips are made from rough rolling mills and finishing mills. The hot strip from the last rolling stand of the finish rolling is cooled by laminar flow to the set temperature. It is coiled by a coiler into a steel coil and the coiled steel is subjected to different finishing operations according to the user's different requirements. Lines (leveling, straightening, crosscutting or slitting, inspection, weighing, packaging, marking, etc.) are processed into steel plates, flat rolled and slit strips. To put it simply, a piece of slab is heated after it has been heated (that is, the hot, red hot steel piece on TV), rolled, and trimmed to form a steel plate.
