在整体式连铸辊(非分节辊)外支撑辊中使用滚柱轴承与连铸辊直接接触时，由于连铸辊温度高、载荷大，会导致轴承疲劳和磨损，对轴承的寿命有非常不利的影响。并且由于采用轴承或小型辊与连铸辊进行接触，在连铸开始阶段由于连铸坯温度过高(1400℃左右，连铸坯凝固末端的表面温度在950～1000℃)，该外支撑辊更需采取冷却措施。 When the roller bearing is used in the outer support roll of the integral continuous casting roll (non-segmented roll) to directly contact the continuous casting roll, due to the high temperature and heavy load of the continuous casting roll, it will cause fatigue and wear of the bearing, which will have a negative impact on the life of the bearing. very adverse effects. And because bearings or small rollers are used to contact the continuous casting rolls, the temperature of the continuous casting slab is too high at the beginning of continuous casting (about 1400°C, and the surface temperature of the solidification end of the continuous casting slab is 950-1000°C), the outer support roll More cooling measures are required.
