Process Of Billet Heat Treatment Machine

The billet heat treatment machine is a professional induction heating equipment developed for the forging industry. It is suitable for carbon steel, alloy steel, die steel and special alloy billets, covering open die forging, closed die forging and precision forging processes. This machine is mainly used for pre-forging heating, post-forging normalizing, soft annealing and stress relief. It is widely applied in construction machinery parts, automotive forgings, petroleum machinery, mining accessories, flanges and shaft blank production. The process effectively solves the common defects of traditional furnaces, such as large temperature difference, severe oxidation and forging cracks.

Adopting a continuous feeding structure, the production process includes automatic sorting, centering conveying, rapid induction heating, uniform temperature soaking, constant temperature holding, forging transferring, controlled cooling, tempering and finished product discharging. With intermediate-frequency induction through-heating technology, heat penetrates evenly from the inside to the outside to ensure consistent core and surface temperature, avoiding the problem of uneven heating. For high-hardness alloy billets, the equipment accurately controls the forging temperature range to improve plasticity and reduce forging impact force.

Pre-forging heating is the core procedure of forging production. Precise high-temperature heating refines coarse grains, optimizes internal metal structure and improves ductility, preventing tearing, folding and corner collapse during forging. The post-forging process adopts controlled slow cooling and low-temperature tempering to eliminate forging residual stress, stabilize metallographic structure and balance hardness and toughness. Equipped with an intelligent temperature control system, the machine freely adjusts power and speed according to material and section size.
