What is cold drawn steel?

 Cold drawn steel is fundamentally the hot rolled steel drawn passing through dies to achieve the final shape. The dies apply pressure with the help of some press machines, and after passing this steel through these dies several times, the steel will have the desired dimensions. This process is known as cold drawn, due to the fact that it occurs at room temperature (below...

TMCP Simulation for Hot Rolling of P91 Seamless Steel Pipe

 However, the rolling process of steel tube is complex and difficult to control, which results in narrow technological window of piercing, rolling and sizing, which limits the application of TMCP technology in seamless steel pipe production. The United States and other developed countries have carried out systematic research on TMCP of steel pipes [9, 10, 11, 12, 13],...
