Abstract

The invention relates to an efficient descaling method for square billets. The efficient descaling method comprises a descaling ring device selective adaptability method and a descaling nozzle selective adaptability method. According to the efficient descaling method, the problem that the conventional square billet scaling ring is incapable of descaling thoroughly can be solved; meanwhile, the problems that nozzles on two sides idly spray water and the water source is wasted can also be avoided; efficient descaling can be conducted on all different-sized billets. The efficient descaling method is convenient to use, thorough in descaling, energy-saving, environmental-friendly and the like.

Description

technical field [0001] The invention belongs to the technical field of descaling technology, and relates to a method for efficiently descaling billets in a bar and wire rolling production line in the metallurgical industry. Background technique [0002] Descaling the heated billet is a key process in the production process of hot-rolled rods and wires. If the descaling is not clean, surface quality defects such as pockmarks and pits will occur. High-pressure water descaling is to use high-pressure, high-speed high-pressure water to remove the oxide scale and regenerated oxide scale on the surface of the billet due to heating. The factors that affect the descaling effect are heating temperature, heating time, billet material, and the impact force of the descaling system, and the impact force of the descaling system mainly depends on the injection pressure, injection height, injection angle, water consumption of a single nozzle, inclination angle, and deflection angle , nozzl...
