Introduction of straightening machines
Series JY straightening machines are high-efficiency machines which are mainly used to straighten precisely and calender metal bars peeled. They can use special curve between the two straightening rolls to straighten and calender bars. The equipment contains main machines, cooling lubricant system , electrical system, transfer system and auxiliary machines. (The pictures are as below.)
