Equipment characteristics of intermediate frequency furnace
1、节约特点
1. Economical characteristics
由于中频感应加热的原理为电磁感应，其热量在工件内自身产生，普通工人用中频电炉上班后十分钟即可进行锻造任务的连续工作，不需烧炉专长工人提前进行烧炉和封炉工作。由于该加热方式升温速度快，所以氧化极少，中频加热锻件的氧化烧 损仅为0.5%，煤气炉加热的氧化烧损为2%，燃煤炉达到3%，中频加热工艺节材，每吨锻件和烧煤炉相比至少节约钢材原材料20-50千克。其材料利用率可达95%。由于该加热方式加热均匀，芯表温差极小，所以在锻造方面还大大的增加了锻模的寿命，锻件表面的粗糙度也小于50um工艺节能，中频加热比重油加热节能31.5%～ 54.3%，比煤气加热节能5%～40%。加热质量好，可降低废品率1.5%，提高生产 率10%～30%，延长模具寿命10%～15%。
Due to the principle of medium frequency induction heating being electromagnetic induction, its heat is generated within the workpiece itself. Ordinary workers can continue working on forging tasks within ten minutes after working with a medium frequency electric furnace, without the need for professional workers to burn and seal the furnace in advance. Due to the fast heating speed of this heating method, there is very little oxidation. The oxidation and burning loss of intermediate frequency heating forgings is only 0.5%, the oxidation and burning loss of gas furnace heating is 2%, and that of coal-fired furnace is 3%. The intermediate frequency heating process saves materials, and each ton of forgings saves at least 20-50 kilograms of steel raw materials compared to coal-fired furnaces. The material utilization rate can reach 95%. Due to the uniform heating and minimal temperature difference between the core and surface, this heating method greatly increases the lifespan of the forging die in terms of forging. The surface roughness of the forging is also less than 50um, which saves energy in the process. Medium frequency heating saves 31.5% to 54.3% energy compared to oil heating, and 5% to 40% energy compared to gas heating. Good heating quality can reduce the scrap rate by 1.5%, increase the productivity by 10%~30%, and extend the service life of the mold by 10%~15%.
2、生态特点
2. Environmental characteristics
感应加热炉与煤炉相比，，工人不会再受炎炎烈日下煤炉的烘烤与烟熏，更可达到生态部门的各项指标要求，同时树立公司外在形象与锻造业未来的成长趋势。感应加热是电加热炉中最节能的加热方式由室温加热到1100℃的吨锻件耗电量小于360度。
Compared with coal stoves, induction heating furnaces eliminate workers from being baked and smoked by coal stoves in the scorching sun, and can better meet the various indicators and requirements of the environmental protection department. At the same time, they establish the external image of the company and the future development trend of the forging industry. Induction heating is the most energy-saving heating method in electric heating furnaces. Heating from room temperature to 1100 ℃ consumes less than 360 degrees of electricity per ton of forgings.
