Progress on research of induction heating in Baosteel

Owing to the development of newproducts and higher requirement of product properties,the current existing induction heating technology of Baosteel can no longer satisfy the newrequirements of the product line.Control of the induction heating temperature to an appropriate value is a key consideration in induction heating technology. To obtain acculturated temperatures,investigations were focused on the parameters of an induction heating system,including those of induction heating equipment and heating processes. In these investigations,computer simulation was used to model the induction heating process,followed by physical experimentation to verify and improve the simulation model; finally,optimized induction heating parameters were suggested. The use of computer simulations dramatically decreased physical experimental times,and the computed heating parameters were used to guide the physical experimentation and design of the product line; this increased the efficiency of subsequent investigations. This study focuses on the development of induction heating technology in Baosteel,which includes the overall induction heating technology used in manufacturing backup rollers and in the thermomechanical control process.
