Method for designing equipment removing oxide skin on surface of slab band

Abstract

The invention provides a method for designing equipment removing oxide skin on a surface of a slab band. The method comprises design of a brush roll transmission device, design of an upper brush roll synchronous device, design of an auxiliary transportation device, design of an oxide skin sweeping device, design of a dust collecting device and design of a matched frame, wherein the design of the brush roll transmission device is used for removing the oxide skin on two surfaces of the slab band; the design of the upper brush roll synchronous device is used for leading the axial lead of the upper brush roll not to incline when the upper brush roll is adjusted and displaced; the design of the auxiliary transportation device is used for transportation of the slab band in and out the brush roll; the design of the oxide skin sweeping device is used for sweeping the oxide skin on the surface of the slab band; the design of the dust collecting device is used for collecting oxide skin dust which is brushed by the brush roll or raised by sweeping; and the design of the matched frame is used for installing and fixing the device design. The method can effectively remove the oxide skin attached on the surface of the slab band under high temperature state and sweep the oxide skin cleanly, and also has the function of dust collection.

Description

technical field

[0001] The invention belongs to the technical field of metallurgical equipment, and in particular relates to an equipment design method for removing scale on the surface of a strip. Background technique

[0002] Alloy strips, especially copper ingots, must be heated to the required hot-rolling temperature in a heating furnace before they can be hot-rolled before being hot-rolled. In contact with oxidizing gases in the atmosphere, a hard oxide layer will be formed on the surface, which is also commonly known as oxide skin.

[0003] If the scale cannot be removed in time before hot rolling, the scale will be pressed into the surface of the strip after the hot rolling of the copper ingot, resulting in the formation of copper rust and pits, which will affect the quality of the product. At present, on hot rolling equipment, especially on copper strip hot rolling equipment, the entire unit is not equipped with a structure to remove scale, and the scale has been cl...
