At present scientific and technological base of large shale mill industry weak gangue grinder manufacturers, since the reform and opening up, shale mill industry market for technology as the main way to improve the level of product technology, but also the face of foreign competitors in China the grim situation of investment in enterprises, most enterprises in scientific research, new product development, technological innovation and business management, energy and capital investment are at a standstill. Product variety, especially domestic shale mill is the key equipment urgently needed national construction can not meet the requirements, and there is low-tech products, unstable product quality, production rate and other issues. Our shale mill industry should seize the opportunity to accelerate development, we must first reform efforts in science and technology, independent innovation. As China's economy continues to develop, the national policy has been actively introduce advanced production technology and processing equipment and technology, so that our shale mill continuous innovation and development of large coal waste grinder, now has achieved very good results. With the continuous development of society, our shale mill market with great development potential and market advantage. Shale crusher hammer forging heating note the following five points: 1. Oxidation: When heated gangue grinder hammer surface easily with oxygen to form oxide. Scale not only makes the hammer loss (heat loss per 1% to 3 per cent of the total weight of steel), but also reduces the surface quality, but also to accelerate the abrasive wear. 2. decarbonization: carbon coal waste grinder hammer when heated surface is oxidized burning out, a phenomenon called decarbonization. Decarbonization result, the hammer surface excellent strength and abrasion resistance is lowered. Decarburization depth just not exceed machining allowance. 3. Overheating: the heating temperature exceeds the permitted temperature process specification range, causing the internal organization of gangue grinder hammer metal thick, a phenomenon called overheating. Not only the mechanical properties of the steel has become overheated organization dropped and 4. burnt: metal high temperatures for a long time and then heating the large gangue grinder brand, oxygen furnace gas will penetrate into the internal organization of the large metal pulverized coal gangue machine parts, causing oxidation and grain boundary melting the low melting point grain boundary impurities, destroyed the binding force between metal atoms and thus cracks in the forging process, this phenomenon is called over-burning. 5. Cracks: Cracks causes heating temperature is too high, too fast, and improper heating furnace and other equipment. If the heating rate is too fast or installed furnace temperature is too high, due to the steel table, where the temperature difference is too large, resulting in great stress, causing cracks. It must be used for this type of steel is slowly heated or preheated before.
