中频炉节约特点
Economical Characteristics of Medium Frequency Furnace
●加热速度快、生产效率高、氧化脱炭少、节省材料与成本、延长模具寿命
High heating speed, high production efficiency, less oxidation decarbonization, saving material and cost, prolonging die life
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，不需烧炉专业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，每吨锻件和烧煤保定平面设计培训 保定空调维修 保定管道通风 包装盒定做 化粪池模具 废旧电缆回收 不锈钢铸件 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%。
Because the principle of medium frequency induction heating is electromagnetic induction, its heat is generated in the workpiece itself. Ordinary workers can carry out continuous work of forging task in 10 minutes after working with medium frequency induction furnace. No professional workers need to burn and seal the furnace in advance. Because of the fast heating speed, the oxidation loss of forgings heated by medium frequency is only 0.5%, that of gas furnace is 2%, that of coal-fired furnace is 3%, and that of medium frequency heating process is material-saving. Compared with coal-fired furnace, heated by medium frequency can save at least 20-50 kg of steel raw materials per ton. Its material utilization rate can reach 95%. Because the heating method is uniform and the temperature difference between core and surface is very small, the life of forging die is greatly increased in forging. The roughness of forging surface is also less than 50um, and the heating energy of medium frequency heating specific gravity oil is 31.5%-54.3% and 5%-40% than that of gas heating. With good heating quality, the scrap rate can be reduced by 1.5%, the productivity can be increased by 10%-30%, and the service life of the die can be prolonged by 10%-15%
