High manganese steel has become the leader in many kinds of crusher equipment. Since the crushing equipment is a product that often deals with stones, the material of E plate has become a key factor to check whether the Gravel crushers equipment can produce efficiently. According to the current assembly structure of crushed stone products, usually consisting of a movable jaw plate and a fixed jaw plate, we all know that the jaw crusher's Gravel crushers is subject to work hardening when subjected to severe impact and strong pressure deformation during use. Martensite is formed, which can form a high wear-resistant surface layer, while the inner layer maintains excellent toughness, so even if it is worn very thin, it can withstand a large impact load, so if it is to be large The crushed stone crushing production requires the overall fixing and calibration of the E plate. Hubei Therefore, as a whole, whether it is a jaw or a counterattack, the accessories need to be calibrated as a whole, so that the quality of the whole machine can be efficiently produced later.
