Reduce the cost of steel production of slab continuous caster oil and gas

Reduce the cost of steel production in 2019 - for the modification of the slab continuous caster for oil and gas 05 - 02 a steel mill roller of slab casting machine group, all bearing is lubricated by glycerol, in actual production application, because of the bad bearing's condition, overload, high temperature, extremely low speed, accompanied by steam and housings are susceptible to water and outside dirt intrusion and hazard bearing. Glycerin is easily within the high temperature bearing, carbide and jam glycerin pipeline, the influence of such factors as the lubricant does not reach the designated position, bearing damage and glue roller occur frequently, every year to spend a lot of cost, and bring adverse effect on production and product quality. After steel mills constantly trying, found that traditional lubrication methods are not effective for bearing lubrication, and lubrication oil and gas, effectively solved this problem. Due to the lubrication requirements of oil and gas bearing seat must have proper sealing, so keep the interior of the bearing seat in transformation of certain positive pressure, so that it can prevent external cooling water and iron oxide into the bearing internal, spillover of compressed air at the same time will take away a lot of heat, makes the bearing has a good running environment, coupled with continuous supply of lubricating oil, to avoid the abnormal damage of bearing, thus greatly improve the bearing and roller group life. Facts have proven that in the environment under the condition of high temperature, impurities and moisture more use of lubrication oil and gas than glycerol lubrication effect is better, can bring significant for steel enterprise economic benefits and environmental benefits.
