Introduction to Heat Treatment Furnace Quenching Process and Cooling Techniques

The heat treatment process of quenching in a heat treatment furnace involves heating steel to a temperature above AC3 or AC1, holding it for a certain period, and then cooling it at an appropriate rate to achieve martensite and/or bainite structures. The purpose of quenching is to enhance hardness, strength, and wear resistance to meet the performance requirements of parts. The quenching process is widely applied across various industries, such as tools, measuring instruments, molds, bearings, springs, and components in vehicles, tractors, diesel engines, machining centers, pneumatic tools, drilling equipment, agricultural machinery, petroleum equipment, chemical equipment, textile machinery, and aircraft.
