從金屬學(xué)角度來看，熱軋與冷軋的界限應(yīng)該以金屬再結(jié)晶的溫度來區(qū)分，即低于再結(jié)晶溫度的軋制為冷軋；高于再結(jié)晶溫度的軋制為熱軋。而鋼的再結(jié)晶溫度一般在450℃～600℃范圍之內(nèi)。

From the point of view of metallization, the boundary between hot rolling and cold rolling should be distinguished from the temperature of recrystallization of metal, that is, the rolling that is lower than the recrystallization temperature is cold rolling, and the rolling that is higher than the recrystallization temperature is hot rolling. The recrystallization temperature of steel is generally within the range of 450 ~ 600.

軋鋼原料：

目前主要為連鑄坯，另外還有鋼錠，段軋鋼等，正確的選擇坯料的種類，斷面形狀和尺寸大小以及重量對軋鋼生產(chǎn)具有重要意義。

Rolling material:

At present, mainly for continuous casting billets, as well as steel ingots, section rolling, etc., correctly choose the type of billet, section shape and size and weight are important for steel rolling production.

單就冷軋機(jī)的軋制速度而言，其型號就可分為兩種，一種是每秒線速度在3米的冷軋機(jī)，還有一種則是線速度在20米冷軋機(jī)，后面這一種設(shè)備已經(jīng)可以算得上是快的了。

As far as the rolling speed of the cold rolling mill is concerned, the model can be divided into two types, one is a cold rolling mill with a line speed of 3 meters per second, and one is the line speed in the 20 meter cold rolling mill, and the latter is the fastest.

軋鋼機(jī)在市場中的成長特別注重對自身品質(zhì)的塑造。并且在市場中也需要品質(zhì)軋鋼機(jī)械來裝飾，只有這樣在能塑造出一個良性發(fā)展的市場環(huán)境，才能令自身在這樣的良性發(fā)展的環(huán)境中成長的更加的快速。

The growth of rolling mills in the market pays special attention to the shaping of their own quality. And in the market also needs excellent quality steel rolling machinery to decorate, only in this way can create a benign development of the market environment, to make itself in such a benign development of the environment to grow more fast.
