Abstract

The invention provides a novel rolling mill roller changing device which comprises guide rails, a mill housing, auxiliary hydraulic cylinders, two rolling mill bed plate, bed plate lining plates and a mill housing lining plate. The two rolling mill bed plates are parallelly arranged, a connecting rod is arranged between the two rolling mill bed plates. The mill housing is perpendicularly arranged between the two rolling mill bed plates. The auxiliary hydraulic cylinders are arranged between the connecting rod and the mill housing. The bed plate lining plates are arranged on all the inner side upper surfaces and the inner side faces of the rolling mill bed plates. The mill housing lining plate is fixedly connected into a groove below the mill housing. The mill housing lining plate and the bed plate lining plates are subjected to contact friction when the mill housing slides. By adoption of the novel rolling mill roller changing device, the archway and a roller system which are located on the operation side are pulled out through the auxiliary roller changing hydraulic cylinders, the roller changing efficiency is improved, the roller changing time is shortened, and the novel rolling mill roller changing device has great significance for improving the roller changing efficiency and the rolling efficiency.

Description

technical field

[0001] The invention belongs to the technical field of rolling mill equipment, and in particular relates to a novel rolling mill roll changing device. Background technique

[0002] Hot-rolled strip steel and section steel are widely used due to their excellent mechanical properties in civil construction, industrial construction, bridge construction, petroleum industry, high-rise buildings, underground railways, mine roadways and industrial steel structural parts. The development of steel rolling production is not only determined by the increase in the speed of the main steel rolling equipment (rolling mill) and the shortening of the rolling cycle, but also largely depends on the continuous improvement and improvement of the steel rolling auxiliary equipment. The degree of mechanization and automation of steel rolling auxiliary equipment and the level of production capacity directly affect the development of modern steel rolling production and the improvement ...
