<p>Provided is an apparatus and method for continuously processing a long bar by heat treatment using induction heating. The method includes checking and preparing carbon steel and low-alloy steel material 1; feeding the prepared material 1 into a continuous induction-heating quenching furnace 10, heating the material 1 at a temperature of 860 °C to 900 °C, spraying a cooling water on the heated material 1, and completely quenching the material 1; horizontally conveying the quenched material 1 by an automatic conveyor unit 20; feeding the conveyed material 1 into a continuous induction-heating tempering furnace 30, heating the material 1 at a temperature of 550 °C to 690 °C, and completely tempering the material 1; checking the tempered material 1 and correcting a deformed part of the tempered material 1; and relieving stress from the corrected material 1 and finally checking the material 1.</p> |
