The impact of high chromium alloy hammer head casting process on quality produced by the stone Crusher factory:
High chromium alloy hammer head has always been the fist of Shandong Sanxiang Heavy Industry Co., LTD. Crusher accessories products sales, because of its cruel production environment, belongs to the machine wearing parts inside the purchase frequency is relatively high. Over the years, the company has always insisted on improving and upgrading the casting process of the crusher mills hammer head, and strive to produce better and better quality products for our customers to purchase and use.

So in the process of upgrading the high chromium alloy hammer head casting process, what will be the main impact on the quality?
First: material proportioning process. High chromium alloy hammer head is mainly composed of chromium, carbon, manganese, molybdenum, nickel and other metal elements, and the main elements (C, Cr, Si, Mn) ratio is unreasonable or harmful elements (S, P) content exceeded, the mechanical properties of the alloy hammer greatly reduced, light wear serious, heavy hammer fracture. Therefore, in the actual production and manufacturing process, Shandong Jinbaoshan Machinery Co., Ltd. strictly controls the content of harmful ingredients in raw materials, and optimizes the chemical composition matching of the main elements of high-chromium alloy hammer head materials to obtain excellent comprehensive performance.

Second: when the casting process is not controlled properly, there will be casting defects such as slag inclusion, shrinkage holes, cracks on the surface or inside of the hammer head, which greatly reduces the mechanical properties of the high chromium alloy hammer head, and causes the hammer head to break in serious cases. In the casting process, our company adopts measures such as horizontal casting (or inclined casting), rational use of external cold iron and heating riser, strict control of casting temperature and pouring speed, etc., to form a good solidification sequence and feeding conditions, so that the production of high chromium alloy hammer crusher mills head to obtain dense internal organization.

Third: When the heat treatment process is unreasonable, a large number of mesh carbides are precipitated in the matrix of high chromium alloy hammer head, which will largely cut the matrix structure, greatly reduce the impact resistance of the matrix, and cause the hammer head fracture in serious cases. According to the material characteristics of the hammer, our company reasonably chooses the quenching temperature, holding time and quenching medium, strictly controls the heating rate and cooling rate, and ensures that the hammer has sufficient impact toughness under the premise of the matrix material uniformly dispersed a certain amount of carbide with high hardness, as the matrix strengthening phase, greatly improving the wear resistance of the high chromium alloy hammer.
From the above points, we can realize the importance of the stone crusher mills machine supplier factory's strict control of the high chromium alloy hammer casting process, which requires you to find the crusher hammer manufacturer when you buy the hammer. Shandong Sanxiang stone cruhser mills machine plant Foundry is a qualified and mature crusher alloy hammer manufacturer, only in this way can we strictly control every production detail in the production process of high chromium alloy hammer.
