The heating part of the intermediate frequency furnace is oxidized only by 0.5%, but the use of gas furnace heating, there will be two percent oxidized burns, other heating equipment, a higher degree of damage.
The heating rate is very fast, work efficiency than other heating equipment to highlight the use of oxidized decarburization material less, IF induction hot forging furnace can be a good material and production cost savings, but also to extend the service life of the mold being processed. Because the frequency induction furnace induction heating works is the electromagnetic induction, this induction heat mainly from the processing of the parts themselves.
IF industrial induction furnace process is saving material, and coal-fired furnace than, probably heating the forgings per ton of steel can save at least twenty to fifty kilograms, the material utilization rate has reached 95 percent.
Under normal circumstances, the workers use the IF furnace in the work of ten minutes can be, so that continuous forging work tasks. There is no need to have a special furnace workers in the workers before work to do a good job burning furnace and sealed furnace, which saves a lot of human resources. Because of the rapid heating medium-frequency electric furnace, which makes the heated objects are rarely subject to oxidation.
