Intermediate frequency furnace is a power supply device that converts power frequency 50HZ AC into medium frequency (above 300HZ to 1000HZ), converts three-phase power frequency AC into direct current after rectifier, and then converts direct current into adjustable intermediate frequency current, supplies intermediate frequency alternating current flowing through the capacitor and induction coil, and generates high-density magnetic force lines in the induction coil. And cut the metal material contained in the induction ring, creating a large eddy current in the metal material. How should we use the dry beating material with the medium frequency furnace? ** Anaijie dry punching material manufacturers will take you to understand the punching operation of medium frequency furnace.

1, check whether the refractory layer is damaged, the damaged place is filled with glass water and refractory materials;

2, the cut asbestos cloth neatly placed on the bottom of the furnace and the furnace wall, in the furnace with iron blocks to fix the asbestos cloth, overlapping without leakage;

3. Evenly add the charge to the bottom of the furnace, and tie it evenly with the vibrator;

4, the bottom of the furnace layer knot, each layer knot thickness control at about 60㎜;

5, hardness check qualified, add the next batch of beating charge after shaving;

6, after tying the bottom of the furnace, add the crucible, and shave around the crucible;

7, the outer surface of the crucible should be cleaned, there should be no rust, oil stains and other debris affecting the quality of the furnace lining;

8. Add part of scrap steel into the crucible, and then put it into the furnace;

9. Place the crucible in the central position of the furnace, measure the distance between the outer wall of the crucible and the inner wall of the furnace body at different positions and of the same height with aluminum wire. If the thickness is uniform, fix the crucible with wood blocks at the furnace mouth;

10, the lining is also layered knot, the height of the lining knot a layer shall not exceed 100㎜, generally controlled in 50 ~ 60㎜ or so, between the layer and the layer after shaving to add the next batch of hit the furnace material;

11. If the furnace is not fixed with wood blocks, each layer of lining is tied, and aluminum wire is used to measure whether the thickness of the lining is uniform, especially at the bottom of the knotted lining.

12. The upper layer of the furnace lining Z shall be knotted with glass water lining material, but it must be noted that the melting position shall not be knotted with glass water lining material;

13, out of the steel mouth to make smooth transition;

14. There shall be no gap between the lining and the nozzle to prevent steel leakage during steel production.
