Mold steel manufacturing is the basis for the entire industrial manufacturing technology and equipment, electronics, automotive, electrical, electronics, instrumentation, home appliances and telecommunications products, 80% to 90% of the parts have to rely mold forming, determines the shape of the mold of these products shape, processing quality and precision mold will determine the quality of these products. The future of China's mold industry after the restructuring, will be increasingly high precision molds, mold steel requirements are also increasing. For a quenching medium cooling during the quenching operation. Mainly used in high, medium carbon steel parts, in order to ensure adequate hardened layer to prevent quenching crack. A process used to reduce the deformation. Commonly used in the water - oil, water - air, oil - air and other media. Slightly removed from the workpiece furnace stay a while quenching into water "cold be quenched" in the air also belongs dual media quenching. From this point of view SKH-9 hardness, on the one hand SKH-9, this winter seems to be earlier than in previous years, even holding similar to last year's operating margin rate of decline in the raw material market pressures to be overlooked; on the other hand, up to In early October, focusing on steel stocks are still up to 15.689 million tons of steel, higher than normal inventory levels of nearly 3 million tons, 2.189 million tons Yijiao same period last year, with the winter near, corporate demand for return of funds to the stock will have The increase in this process may also take the initiative to cut production in order to reduce pressure on the stock of finished products. Taking into account the cuts during the APEC meeting in early November, Hebei and other places likely to face a decree, if the supply is gradually reduced expectations are confirmed, then the pressure on the raw materials market will be significantly higher. The use of the workpiece is heated to a higher temperature and a longer time for the aging treatment aging treatment process, known as artificial aging treatment, when the workpiece is placed at the natural conditions or prolonged storage at room temperature aging phenomenon occurs is called the natural aging treatment. The purpose of the aging process, eliminate the internal stress of the workpiece, stable organization and size, to improve the mechanical properties. The source of high energy beam heat treatment usually refers laser, electron beam, ion beam or the like. Their common features are: supply of steel mold surface power density of at least 103W / cm 2. Their common features are: fast heating, heating area can be selected according to the needs of small deformation of the workpiece, no cooling medium SKH-9 high-speed steel, handle clean environment, good controllability, easy to implement automated processing. At home and abroad on the principle of high-energy beam of heat treatment, process etc to invest more research, more mature laser transformation hardening, small and medium-power electron beam treatment of ion implantation and improve die life gained a level applications . From the trend of the domestic steel price index situation, late June, the trend began long products price index was weaker than plate price index. The continuation of this trend in the third quarter, SKH-9 clinker, and long products price index weak trend trend of expansion. The third quarter of this year, long products price index trend has been weaker than the price index sheet, and long products price index accelerated in mid-September to late fall when. Behind this is the real estate industry continues to decline in influence. These defects with the increase in the size of the ingot mold and increasingly serious. On the other hand, osteoporosis, dendrimers and carbides must guarantee the elimination of defects such as forging a certain ratio, the smaller the ingot is not desirable. For this contradiction, the general approach is to ensure that the conditions under forging ratio, try using small ingots. Because of the small size of the ingot cooling conditions were better, more dense internal organization ingot casting flaw less serious. For high-alloy (eg Cr12 type ledeburite) steel, generally smaller size should ingot, forging ratio by forging methods to ensure.
