Description

Roughing mill with iron scale removing equipment Technical Field The utility model relates to the field of scale removal equipment, in particular to a roughing mill with scale removal equipment. Background The roughing mill is used for primarily rolling a steel billet into an intermediate blank with a certain thickness and shape in steel rolling production, and is required to remove iron scales on the surface of the steel billet before rolling, if the iron scales on the surface of the steel billet are not removed before rolling, the iron scales are pressed into the surface of strip steel by a roller in the rolling process, so that the surface quality of the strip steel is affected, the defects such as pits and pits are caused on the surface, in addition, the friction force between the roller and the steel billet is increased due to residual iron scales, the abrasion of the roller is accelerated, the service life of the roller is shortened, and the production cost is increased. The common scale removing equipment adopts a high-pressure water descaling system, water is pressurized to a certain extent by a high-pressure water pump, a fan-shaped water beam with strong impact force is formed through a descaling nozzle and is sprayed on the surface of a steel billet, and the high-pressure water beam cuts, rapidly cools and contracts the scale so as to peel off the scale from a base material of a matrix and wash the scale. However, the scale removal mode is relatively wasteful of water resources, and is unfavorable for the development of energy conservation and emission reduction. Based on the above, the utility model provides a roughing mill with an iron scale removing device.
