The working characteristics of the dedicated reducer for steel rolling mill are low speed, heavy load, high impact load, frequent impact frequency, and continuous operation. With the rapid development of China's steel rolling industry, the continuous expansion of steel varieties, the increase of production, the improvement of rolling speed, and the increase of rolling load, it is required that the gear transmission device of the rolling mill has sufficient bearing capacity, namely high strength, high precision, high service life, and high reliability. Therefore, modern large and medium-sized rolling mill gear devices generally use precision machined hard tooth surface and medium hard tooth surface involute cylindrical gears, and adopt design and manufacturing technologies such as gear tooth shaping, deep carburizing, and shot peening strengthening. Welded structure reducers have also been widely used. The gearbox housing and cover are both welded structures, and the welded large gear structure is gradually replacing the previous cast gear and ring gear structures.
