| Abstract: | For improving the production capability and technology level of 1780mm hot-olled steel production line in Rolled Steel Mill of Benxi Beiying Iron & Steel(Group) Co.,Ltd.,the causes that seriously influence production,i.e.the high frequency of the high pressure oil pump damage of hydraulic circuit are analyzed,and thus the corresponding countermeasures are proposed.The results of production show that the operating life of oil pump is extended,and the operation rate and productivity are increased,and as a result the production cost is reduced. |
