We often say that steel is cold rolled steel strip, hot rolled not commonly used, but this can be a customer asked, before both of the following differences:
1. use steel strapping not the same degree of automation, General cold rolled steel strips using a manual steel strapping or a pneumatic steel strapping and automatic steel strapping package require higher levels of use of hot-rolled steel strip.
2. the soft hot-rolled strip steel, tensile strength yield is low, finished appearance not readily oxidizable, cold-rolled strip steel quality is hard, yielding, high tensile strength, finished appearance not easily rust and hot-rolled steel strip elongation and packaged hot-rolled strip steel, was 40th, and cold-rolling is Q195,Q235,Q345, and so on.
3. on the treatment process of hot burning blushed when processed into the desired thickness steel billets, cold it was on the basis of hot have cooled further processing, of course, is the cold-rolled, mill, without increased after cold rolling strip steel heat density, hardened straight.
