Surface hardening equipment [PDF]
Chemical and Petroleum Engineering, 2013 Use of a new device UDGZ-200 is considered for surface hardening. Its use increases the service life of body components, gear connections, crane wheels and rails, dies, etc., due to a marked reduction in machine and equipment down time. Its introduction does not require workshop modernization: it is capable of compensating for a lack of traditional ...
