Forging Co., Ltd., Luoyang Super League tells you forging quality assurance measures: some domestic enterprises have been equipped with the latest instrumentation and testing technology, the use of modern computer-controlled automation of data processing within the ring ultrasonic flaw detection system, using a variety of special automatic ultrasonic inspection system, the completion of various quality system certification. High-speed heavy gear forging key production technology products continue to be tackled within the ring parameters, and on this basis to achieve the industrial production. The introduction of foreign advanced production technology and key equipment on the basis of China has been able to design and manufacture its own high-speed heavy gear forging production equipment, the equipment is close to the international advanced level, technology and equipment to enhance the effective promotion of the domestic forging industry development of. Forging Co., Ltd., Luoyang Super League for you about the forging process: smelting forging large forgings required the use of large ingots. Large single ingot lies within the range of 30 to several hundred tons. Ingot, the more severe segregation and other metallurgical defects. Therefore, large forgings steel smelting requirements are very stringent. To ensure a large ingot casting, are generally required to use two or more combined with furnace smelting furnace casting, so you do not increase the capacity of a single furnace, reducing the length of time due to the casting refractory erosion and reduce the temperature of the molten steel. Selection of raw materials within the ring must stand, and strictly control smelting smelting difficult to remove harmful elements such as boron, copper, tin, antimony, arsenic, etc. Steel can be the beginning of a large alkaline arc furnace smelting, and other large-scale converter ring gear processing must be carried out at the beginning of refining molten steel refining and vacuum degassing of steel to minimize sulfur, phosphorus, and gas content, in order to obtain sulfur , was less than 0.005% phosphorus, less than 2% of hydrogen, oxygen less than 30%, less than 40% of the high nitrogen purity steel. In order to reduce segregation and defects, a large ingot casting foundry to adopt new technologies, such as spin casting method, the hollow ingot casting and directional solidification method. _ Xuchang ring gear forging ring gear forging workmanship _ Super League Super League from Luoyang Forging Limited.
