The maintenance of intermediate frequency furnace

1.The roast of furnace
For dry type furnace, the furnace of the steel do not need be taken out. When roasting the oven, it must be based on the principle of add sauce and infill to avoid local flint and melt the tank, and make the dry material to collapse. So try to save a few small materials in front of the oven. At the same time in the process of heating up to strictly observe the steel case, so when there is a bowl, serious should reduce current if the electric current will cause steel arc breakdown and cause the collapse of the refractory material.

2.Metal furnace charge

Usually, the block size should be appropriate when adding the metal furnace charge, generally no more than the 1/2, inside the stove furnace charge several times should be small batches to join at the same time, To add a little material, when the refractories material is at the bottom, not only ensure jam material, it also can reduce the burden on the impact of the furnace wall, furnace bottom.

3.Draw a charge
When iron liquid came out, the rest of the liquid iron in does not affect the material in the furnace and the loading without splash can more appropriately. It can not only increase the fusion rate of metal charge, also can avoid burden directly hit bottom, a pack of iron liquid after, furnace body should be rolled back, in order to reduce furnace iron liquid of intermediate frequency furnace wall after baking.
