what is the productivity of cold mill

Development of the cold planer or milling machine began in the late 1970's when a grade trim-mer was upgraded to mill asphalt pavement. Since that time significant advancements in size, horsepower, milling width, milling depth, production, and cost-efficiency have been made.

China Stainless Steel Mkw Cold Rolling Mill

John G. Lenard, in Primer on Flat Rolling (Second Edition), 2014. 7.17 Reduction of Local Buckles. Even though the cold mill itself may cause local buckles, the majority of the local buckles are caused by the feed stock from the hot mill (Melfo et al., 2006). Therefore, proper monitoring of the hot band profile and mechanical properties will be the first choice to reduce local buckles.

Advanced Reversing Cold Mills by Primetals Technologies

After having passed through the cold rolling mill, the steel strip is hardened. This entails that it is no longer able to be processed further. This is why, in order to make the steel cold deformable, it needs to undergo a heat treatment. This can be done in the batch annealing section or in the continuous annealing and processing line.
