steel billet induction preheating machine/furnace

steel billet induction reheating furance is the core front-end heating equipment specially designed for the full set of steel rolling mill production line. It is mainly used for continuous and rapid uniform heating of square steel billets, round steel billets, alloy steel blanks and low-carbon steel raw materials before rolling. The equipment adopts medium-frequency induction heating technology, which can quickly raise the billet temperature to the ideal rolling forming temperature in a short time. It is an essential thermal processing equipment to ensure stable rolling quality, reduce rolling resistance and improve the finished steel profile yield in the whole rolling production process.

The standard working process of the induction preheating furnace in the rolling line includes automatic billet sorting, mechanical feeding, segmented rapid preheating, constant temperature homogenization and synchronous discharging to the rolling mill. According to different steel material grades and rolling specifications, the equipment accurately controls the heating temperature between 1050℃ and 1250℃. The intelligent temperature control system ensures that the temperature deviation of each steel billet is controlled within ±8℃. After uniform preheating, the internal metal structure of the steel billet is fully activated, the plasticity is greatly improved, and the internal stress is evenly distributed, which effectively avoids rolling cracking, surface folding, bar bending and other defective problems during the subsequent rolling process.

This induction billet preheating equipment perfectly matches the full-automatic operation rhythm of the whole steel rolling production line. It features fast heating speed, stable continuous operation, simple maintenance and long service life. It can greatly reduce the failure rate of rolling equipment, improve the surface quality of finished steel bars, steel angles, steel channels and other profiles, and effectively reduce production costs. Therefore, the steel billet induction preheating furnace has become the standard supporting heating equipment for new generation intelligent steel rolling production lines, widely used in steel plants, metal material processing factories and mechanical steel supporting production workshops.
