Abstract

The invention provides combined type oxide skin removing equipment and a removing method. The combined type oxide skin removing equipment comprises an uncoiler, a stretch bending descaling mill, power-provided tension machines and a coiler; the uncoiler is used for unfolding a rolled metal plate and conveys the metal plate to the stretch bending descaling mill, the stretch bending descaling mill is arranged on one side of the uncoiler and is used for crushing thick oxide skin in the stretch bending process, the multiple power-provided tension machines are arranged on one side of the stretch bending descaling mill, and the coiler is arranged on one sides of the power-provided tension machines. The combined type oxide skin removing equipment is characterized by further comprising a restraining milling machine and an electrolysis machine, the abrasive material restraining milling machine is arranged between the two power-provided tension machines arranged on one side of the stretch bending descaling mill, and the electrolysis machine is arranged between the two power-provided tension machines arranged between the restraining milling machine and the coiler. The combined type oxide skinremoving equipment has the beneficial effects of being economical, efficient, environment-friendly, and capable of completely replacing chemical acid pickling for removing the oxide skin.

Description

technical field [0001] The invention belongs to the field of metal descaling equipment, and in particular relates to a composite type descaling equipment and a removal method. Background technique [0002] Because hot-rolled steel is carried out at high temperature, it will inevitably cause a chemical reaction between the steel and the oxygen in the air, and a certain thickness of oxide scale will be formed on the surface. The oxide scale after final rolling is generally composed of three layers, and the steel matrix is ​​from the inside to the outside. Respectively, ferrous oxide accounts for about 40% to 95% of the total thickness of the scale, and is a loose, porous fine crystal structure; the middle layer is ferric oxide, which accounts for about 4% to 14% of the total thickness, and is dense, non-woven. The magnetic structure of the glassy fracture of holes and cracks; the outermost layer is ferric oxide, accounting for 1% to 2% of the total thickness, which is iron oxi...
