The present invention provides a composite scale removal equipment and removal method, including an uncoiler, a stretch-bending scale breaker, a belt tensioner, and a rewinder. The uncoiler is used to unroll rolled metal sheets and transport Stretch bending scale breaker, one side of the uncoiler is equipped with a stretch bend scale breaker, the stretch bend scale breaker is used to break the thicker scale in the process of stretch bending, and the stretch bend scale breaker is One side of the scale machine is provided with a number of belt power tension machines, and one side of the belt power tension machine is provided with a winding machine, which is characterized in that it also includes a restraint grinding machine and electrolysis equipment. Abrasive constrained grinding equipment is provided between the two belt tensioners on one side, and electrolysis equipment is installed between the two belt tensioners between the constraint grinder and the winding machine. The beneficial effect of the invention is that it is economical, efficient, environment-friendly and completely replaces chemical pickling to remove scale.
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...
