High-efficiency hot rolled steel plate differential leveling and dedusting device

Abstract

The invention provides a high-efficiency hot rolled steel plate differential leveling and dedusting device. The high-efficiency hot rolled steel plate differential leveling and dedusting device comprises a fixed housing, grinding rollers, recoiling machines, guiding rollers, a waste material placing box, supporting racks, a first motor, adjusting pressing rods, a hot rolled steel plate, a fixed plate and a second motor. The grinding rollers are arranged in the fixed housing; the fixed plate is fixed on the inner upper side of the fixed housing; the adjusting pressing rods are arranged between the fixed plate and the grinding rollers; the coiling machines are arranged on the left and right sides of the supporting racks; the guiding rollers are arranged on the upper portions of the supporting racks; and the supporting racks are arranged on the left and right sides of the fixed housing. By arranging a shock absorbing spring, the shock absorbing effect of the rollers is favorably improved; by arranging the supporting racks, the heights of the supporting racks are conveniently adjusted; and by arranging lattice-shaped convex marks on a first roller, the dedusting effect is favorably improved, so that the device is more convenient to use.

Description

technical field [0001] The invention belongs to the technical field of hot-rolled steel plates, and in particular relates to a high-efficiency differential smoothing and derusting device for hot-rolled steel plates. Background technique [0002] The hot-rolled steel plate produced at high temperature will form a layer of iron oxide scale with a thickness of about 0.01 mm and brittleness at room temperature after cooling. The hardness of this layer of iron oxide scale is greater than that of the metal matrix of the hot-rolled steel plate, and It is firmly attached to the surface of the metal matrix of the hot-rolled steel plate. If this layer of iron oxide scale is not removed, after it is deeply crushed and crushed during the cold rolling process, the flaky iron oxide scale is easily embedded in the metal matrix of the steel plate, resulting in product quality defects. [0003] The existing differential leveling and derusting device for hot-rolled steel plates has the proble...
