Multi-station high-frequency quenching machine tool replaces traditional industrial furnaces
The multi-station quenching machine tool is a device that directly heats the workpiece using the principle of electromagnetic high-frequency. Therefore, in many cases, we also refer to high-frequency quenching equipment, high-frequency welding equipment, intermediate-frequency quenching furnaces, and intermediate-frequency smelting furnaces as high-frequency heating furnaces. High-frequency quenching uses the principle of electromagnetic high-frequency heating to heat a metal workpiece A proper temperature is maintained for a period of time, and then immersed in the quenching medium to quickly cool down, thereby greatly improving the strength, hardness, wear resistance, fatigue strength and toughness of the steel to meet the different requirements of various mechanical parts and tools. Metal heat treatment process.
Generally speaking, multi-station quenching machine tools are suitable for the heat treatment of workpieces with simple blank shapes and large batches, as well as the forging, hot stamping, metal melting and other factories in the military, automobiles, tractors, railway locomotives and other industries. use. We mainly summarize high-frequency quenching machine tools and oil-fired industrial furnaces. Compared with natural gas industry, coal-fired industrial furnace, and resistance furnace, the advantages:
1. The heating speed is fast, which can double the production efficiency of high-frequency quenching machine tools and can form a continuous production line with other process equipment.
2. The heating time is short, the efficiency is high, and the efficiency of the high-frequency quenching machine tool can be reached. 80%~95%, the efficiency of high-frequency smelting furnace can reach 65%~75%, while the heating efficiency of flame furnace (oil-fired industrial furnace, natural weather industrial furnace, coal-fired industrial furnace) is only about 20%. The heating efficiency is only about 40%.
3. Using high-frequency quenching machine tool equipment, due to the fast heating speed and short heating time, the oxide scale burn rate of the workpiece is 0.5%~1%, and the oxide scale loss rate generated by the flame furnace is 3%. The equipment saves at least 2% of materials than flame furnaces
