WhatsApp: +86 188380728291) Rolling: To reduce thickness. 2) Annealing: To restore ductility. 3) Slitting: To separate a wide strip into narrower cuts. The rolling process generally begins with material in the annealed condition. The condition of metal ( annealed, tempered) can be defined by the grain structure, or, microscopic structure (microstructure) of that ...
WhatsApp: +86 18838072829In simple terms, cold rolling is the process of strengthening steel by changing its shape without using heat. Cold rolling, unlike hot rolling such as with hot rolled steel, can only occur when a metal is below its recrystallization temperature. Where hot rolling is performed using high temperatures, cold rolling is performed at room temperature.

WhatsApp: +86 18838072829As cold rolling of steel requires a lubricant in order to fulfil the lubrication role, oil is necessary. Hence, wateroil mixtures are used with a percentage of oil in water of approx. 5%. In most cases emulsions are the common coolants for cold rolling, where the oil and the water form a pseudosolution. There are stabile and meta stabile
