在炼钢工业中,除了轧钢设备用的大型轴承之外,近来还需要 LD——转炉和卡尔多转炉用的特大的重型滚动轴承。后者是为了转动盛有钢液的炉子,它支承重约1200吨的荷载。例如作用在250吨转炉每个轴承上的荷载,就相当于四台现代电机车的重量。在炼钢厂的恶劣运转条件下,以及在转炉和卡尔多转炉加料和出钢时,相当缓慢地转动的情况下采用滚动轴承,不能认为是转
In the steelmaking industry, in addition to the large bearings used for steel rolling equipment, large, heavy-duty rolling bearings for LD-converters and Cartel converters are also required recently. The latter is for rotating a steel-laden furnace supporting a load of about 1,200 tons. For example, the load acting on each bearing of a 250-ton converter is equivalent to the weight of four modern electric vehicles. The use of rolling bearings in the case of the harsh operating conditions of the steelworks and in the case of very slow rolling of the converter and Caldo converter,
