The main purpose is to hammer hammer wear and abrasion resistance to the limit. The traditional consumption particularly large hammer crusher hammer, hammer crusher such as mining and other industries in the battlefield and used every day for a lot of work which increases the cost. So for some broken grinding class industry they want to hammer longer usable, so not only can increase the efficiency of the crusher, and can effectively save costs. Hammer crusher wear-resistant high speed when a direct blow to the material, eventually breaking into the appropriate material particle size, the hammer is one of the core parts of hammer crusher, arranged in the hammer crusher rotor shaft, hammer crusher direct hit at high speed material, the extent of wear-resistant is not the same hammer crusher hammer function, the head of the need for good wear resistance and toughness shank also need enough hammer crusher models, the use of carbide hammer good performance on composite hammer wear in the processing time is required to cool, then in a process where it is essential, in order to ensure the quality of the product, Here I introduce some of its cooling requirements knowledge, I hope you read them carefully. 1, when the composite hammer air-cooled, dry place should be scattered; 2, promptly after quenching and tempering, the time interval is generally not more than 4h, the carbon content of steel (carbon content) is low, the workpiece shape simple , should not exceed 16h; 3, before washing After cooling to room temperature, cryogenic treatment or tempering; 4, the time between the welding assembly, composite hammer welding and subsequent heat treatment consisting interval should not exceed 4h.
