1.Difference between cold rolled steel and hot rolled steel


As you can see in the picture, cold rolled surface is smoother.

Hot rolling is the heating of the material during or before rolling. It is generally heated to above the recrystallization temperature before rolling.

Cold rolled steel is the steel produced by cold rolling. Cold rolling is the process of further thinning steel plates to target thickness at room temperature. Compared with hot rolled steel plate, cold rolled steel plate thickness is more accurate, and the surface is smooth, beautiful, but also has a variety of superior mechanical properties, especially machining performance.

Hot rolled steel has low strength, good extension and dull color.

Cold rolled steel has high strength, high hardness and bright surface.

2:The process of cold rolling steel coil


Cold rolling is usually done by longitudinal rolling. The process of cold rolling production generally includes raw material preparation, pickling, rolling, degreasing, annealing (heat treatment), finishing, etc.

3.Common cold rolled steel coil grades


Different levels of cold rolled steel coil have different performance. Therefore, it corresponds to different uses.

Dx51D, Dx52D, Dx53D, DX54D, S220GD, S250GD, S280GD, S350GD, S350GD,

S550GD; SGCC, SGHC, SGCH, SGH340, SGH400, SGH440, SGH490,SGH540, SGCD1, SGCD2, SGCD3, SGC340, SGC340 , SGC490, SGC570; SQ CR22 (230), SQ CR22 (255), SQ CR40 (275), SQ CR50 (340), SQ CR80(550), CQ, FS, DDS, EDDS, SQ CR33 (230), SQ CR37 (255), SQCR40 (275), SQ CR50 (340), SQ CR80 (550)

4.Cold rolled steel coil application

What is the difference between cold rolled steel coil and galvanized steel coil

Cold rolled steel coil refers to the steel coil obtained after rolling by cold rolling mill, or cold hard coil. In practice, we usually refer to the steel coil after cold rolling and processed in the next process as cold rolled steel coil.

Galvanized steel coil is a steel coil obtained by alkali washing, annealing, galvanizing and leveling with cold-rolled coil as raw material. It is also commonly called cold-rolled galvanized steel coil.

How to calculate the "unit coil weight" of cold rolled steel coil?

Unit coil weight refers to the weight of a steel coil. Cold rolled coils vary in size. The small ones are hundreds of kilograms, the large ones are more than ten tons and more than twenty tons.

Thickness * length * width * 7.85 / 1000000 = kg

As a pipe

Formula: (outer diameter - wall thickness) * wall thickness * specific gravity (density) * length

Formula: (outer diameter wall thickness) * wall thickness * 0.02491 * length

Wall thickness = (1431-508) / 2 = 461.5


Think of it as a round bar

Formula: (outer diameter * outer diameter * specific gravity * length) - (inner diameter * inner diameter * specific gravity * length) = weight


According to theoretical calculation, this paper is about 10.7 tons (stainless steel)

About cold rolled steel coil manufacturers in china
