Is rolling under recrystallization, but generally understood as the
use of rolling materials at room temperature. Aluminum cold rolling
is divided into plate rolling and foil rolling, the thickness of
0.15~ above is called plate, 0.15~ below is called foil. Europe and
many use 3~6 continuous rolling mills as cold rolling equipment.
Due to no heating in the production process, there is no hot
rolling often occur pitting and oxide iron defects, good surface
quality, high finish. Moreover, the size precision of cold-rolled
products is high, and the properties and structure of cold-rolled
products can meet some special requirements, such as
electromagnetic properties, deep drawing properties, etc.
Specification: thickness 0.2-4mm, width 600-2000mm, length of steel
plate 1 200-6000mm.

ST12-15; DC01-06
Performance: mainly used low carbon steel, requires good cold
bending and welding performance, as well as certain stamping
performance.
Introduction of hot dip Galvanized Steel plate (silver white)
Hot rolled steel strip or cold rolled steel strip as the base
plate, after continuous hot dip galvanizing process and production,
can prevent the surface corrosion and rust of thin steel plate and
steel strip.
Hot galvanized sheet supplied by cross cutting rectangular plate;
The warp reel is supplied in the form of hot dip galvanized coil.
Because of the different substrate used, hot galvanized steel sheet
can be divided into hot rolled galvanized sheet and cold rolled hot
galvanized sheet, they are mainly used in construction, household
appliances, automobiles, containers, transportation and household
industries and other fields. Especially steel structure
construction, automobile manufacturing, steel plate window
manufacturing and other industries.
1, the characteristics of hot dip galvanized steel plate
Strong corrosion resistance, good surface quality, conducive to
deep processing, economic and practical.
2. Classification and symbol of hot dip galvanized steel plate
According to the machining performance, it can be divided into:
general purpose (PT), mechanical bite (JY), deep drawing (SC),
ultra-deep drawing aging (CS), structure (JG);
According to the weight of zinc layer: pure zinc surface: 100/100
(zinc layer weight is less than 100g/m2),
120/120, 200/200, 275/275, 350/350, 450/450, 600/600;
Zinc-ferroalloy surface is divided into 90/90
(zinc-iron alloy layer weight less than 90g/m2), 100/100, 120/120,
180/180;
According to the surface structure, it is divided into: normal zinc
flower Z, small zinc flower X, light whole zinc flower GZ, zinc
iron alloy XT;
According to the surface quality, it was divided into: group I (I),
group ⅱ (ⅱ);
According to the dimensional accuracy is divided into: advanced
precision A, ordinary precision B;
According to the surface treatment is divided into: chromic acid
passivation L, oiled Y, chromic acid passivation and oiled LY.
