Gear wheel and girth gear steel casting is also called gear ring steel casting,It is an important component of the forging and press machine. Zhengda customize the gear wheel steel casting for size and parameters ,etc according to customers’ actual requirement.The gear wheel steel casting production is in accordance with customer’s requirement and strict control steel casting quality.The heat treatment is the key process that effect gear wheel steel casting quality according to the raw material to set the temperature of heat treatment ,such as medium carbon steel heat treatment in higher carbon content is not suitable adopted higher normalizing temperature and longer heat preservation time , otherwise it will make gear wheel steel casting surface reduced the hardness. Therefore, normalizing is required for slow heating, and after 4 hours, the temperature rises to 810-860℃. After 6 hours insulation, then gear wheel steel casting is taken out of the furnace and cooled at room temperature in the ventilated air.
Steel casting has been widely used in the machine industries, and the applicable scope continues to expand. Therefore,if the production quality can be guaranteed is a very important thing, but due to the steel casting is in the casting process with small problem, so it is particularly important to grasp the technological process。
1. In the process of gear wheel machining, the set machine line process can be arranged several times, which can balance the machining allowance and ensure the machining accuracy and position accuracy.
2. Gear wheel steel casting can be fully quenched and tempered with advanced equipment and technology.So,the gear wheel steel casting can be good mechanical properties to ensure high strength with good plasticity and toughness.
3. Accumulating a wealth of experience in the long time manufacturing with many years of history for manufacturing the gear wheel steel casting.It summarizes a set of anti deformation processing scheme, can effectively prevent gear wheel steel casting from deformation after processing and ensure the equipment transmission stability to improve the design capacity and prolong equipment service life.
