Abstract

The invention relates to an anti-rolling-fracture roll of a hot rolling temper mill. The anti-rolling-fracture roll comprises at least two supporting rolls and work rolls. The at least two supporting rolls are arranged in two rows side by side and rotationally arranged on a movable base through a first bearing assembly. The work rolls are closely attached to the lower portions of the two rows of supporting rolls and rotationally arranged on the movable base through a second bearing assembly. A bearing block of the second bearing assembly is an elastic bearing block. The invention further relates to an application method of the anti-rolling-fracture roll of the hot rolling temper mill. The method comprises the following steps that a steel roll is coiled on a coiling block of an uncoiling machine, the steel roll is opened, and strip steel forwards penetrates a pinch roll; when the strip steel is pressed by the pinch roll, a drive device downwards presses the work rolls to the part, between the uncoiling machine and the pinch roll, of the strip steel; and when the tail of the innermost ring of the steel roll leaves the coiling block of the uncoiling machine, the drive device elevates the work rolls. The anti-rolling-fracture roll is reliable in structure and capable of absorbing vibration and impacts brought by wave shapes of fed materials, the rolling stability is guaranteed, and the surface quality and performance of the strip steel are improved.

Description

technical field [0001] The invention relates to the technical field of steel rolling, in particular to an anti-rolling and breaking roll of a hot-rolling skin pass unit and a use method thereof. Background technique [0002] The hot-rolling tempering unit is an important supporting unit for the hot-rolling main line, and its main function is to level, coil or recoil the strip. Wherein, the leveling takes a certain elongation rate (usually 0.5%-4%) as a control parameter, and the strip steel rolled and cooled (cooled to below 60° C.) in the hot rolling main rolling line is rolled. The purpose of temper rolling is to eliminate the yield platform, expand the shaping range, improve the processing performance; improve the mechanical properties and surface quality of the strip; eliminate or reduce the tower shape. [0003] The specific equipment composition and equipment structure of hot-rolled tempering units in various domestic steel mills are not the same, but walking beams, u...
