摘　　要：目前锻制钢球由于规格较大,锻造后冷却速度缓慢,容易产生网状碳化物超标,如果采用直接水冷将有可能产生大量裂纹。通过采用旋转式喷雾冷却装置对锻制钢球进行喷雾冷却,既能有效地防止网状碳化物超标的产生,又能有效地防止因水冷过快而产生裂纹。Due to larger specifications and the slow cooling speed of forged steel ball after forging, there is prone to excessive net carbide in steel ball. It is possible to generate a large number of cracks as adopting direct water cooling. Spray cooling the forged steel ball by using rotary spray cooling device can effectively prevent the excessive production of net carbide and the crack caused due to water cooling too fast.
