The difference between hot rolled plate and manufacture

1, manufacture surface has the certain gloss hand it feels more smooth, similar to a kind of common steel cup to drink water. 2, without pickling hot-rolled, such as processing, with a lot of ordinary steel plate surface is similar on the market, to red, rusty surface not rusty surface purple ( Tin oxide) 。 Manufacture and the performance of hot rolled plate advantage: ( 1) Higher precision, cold-rolled strip steel thickness difference less than 0. 01 ~ 0. 03mm。 ( 2) Size is thinner and cold rolled the thinnest rolling 0. 001 mm steel belt; Hot rolled the thinnest can achieve zero now. 78mm。 ( 3) The surface quality is superior, and cold rolled steel sheet can even produce the mirror surface; While the surface of hot rolled plate tin oxide, such as pitting defects. ( 4) Can manufacture according to user requirements to adjust its properties such as tensile strength and process performance such as stamping performance, etc. Cold rolled and hot rolled is two different types of steel rolling technology, as the name implies, is cold rolled copper under the condition of steel at room temperature, the hardness of the steel. Copper is hot rolled steel in high temperature circumstances.
