Why is your steel plate induction heating not ideal? Steel plate induction heating equipment will also affect the final result of quenching and tempering.
The hot-rolled bar material that has been quenched and tempered by medium frequency induction heating is rapidly heated to a very fine martensite structure after quenching by austenite, and then tempered at high temperature to obtain fine tempered sorbite. This tempered sorbite has high tensile strength and yield strength, as well as good image and toughness.
Steel plate induction heating quenching and tempering is a dual heat treatment of quenching and high temperature tempering, and its purpose is to make the workpiece have good comprehensive mechanical properties.
Steel plate induction heating has two categories: carbon quenched and tempered steel and alloy quenched and tempered steel. Regardless of whether it is carbon steel or alloy steel, its carbon content is controlled strictly. If the carbon content is too high, the strength of the workpiece after quenching and tempering is high, but the toughness is not enough. If the carbon content is too low, the toughness will increase and the strength will be insufficient. In order to obtain a good comprehensive performance of the quenched and tempered parts, the carbon content is generally controlled at 0.30~0.50%.
