Steel ingot makes the uniform stove of steel ingot internal temperature be referred to as soaking pit.In the broadest sense, heating furnace includes soaking pit and heat-treatment furnace.
Heating furnace operation principle is put the workpiece in inductor (coil), when the alternation that certain frequency is passed through in inductor
During electric current, surrounding produces alternating magnetic field.The electromagnetic induction effect of alternating magnetic field makes the induced-current that closing is produced in workpiece-
- vortex.Distribution of the induced-current on workpiece interface is very uneven, and workpiece surface current density is very high, is inwardly gradually reduced,
This phenomenon is referred to as kelvin effect.The electric energy of workpiece surface high-density current is changed into heat energy, raises the temperature on top layer, i.e., real
Existing surface heating.Power frequency is higher, and workpiece surface and the current density difference of inside are then bigger, and zone of heating is thinner.In zone of heating
Temperature cools down rapidly after exceeding the critical point temperature of steel, you can realizes surface hardening.
Heater for rolling steel typically uses open firing steel ingot or steel billet, and steel ingot or billet surface degree of oxidation can be caused high,
The part blank of heat treatment is generally required before heating is heat-treated or is forged, degree of oxidation is also higher, and therefore, the industry is thirsty
Prestige obtains a kind of low-cost heating part blank and makes the non-oxidizing heating furnace in its surface or soaking furnace apparatus.

The axis of the heating furnace tube and horizontal line angle are 0 °~3.5 °, and the feeding section is higher than discharging section.
On the basis of above-mentioned technical proposal, the utility model can also do following improvement.
Further, the kiln hood boiler tube supporting mechanism, kiln wall and kiln tail boiler tube supporting mechanism are fixed on the converter body support
In mechanism；The stage casing boiler tube supporting mechanism is fixed on the kiln wall.
Beneficial effect using above-mentioned further scheme is to prevent heating furnace two play, ensures that heating furnace is stable.
Further, the burner group includes horizontally disposed multiple burners, and described burner is externally connected to combustion-supporting airduct
Road and gaspipe line.
Further, the kiln wall is heavy, the light fire brick such as refractory fireclay block, alumina firebrick, mullite, can also
It is the kiln that the heat-preservation cotton block such as alumina silicate is built by laying bricks or stones.
The beneficial effects of the utility model are：
1st, the coil outlet automatic cover plate assembly that the utility model discharging opening is set can be outputed material by blank top, then rely on
Self gravitation is automatically fallen off, and covers discharging opening, prevents air from causing material in boiler tube to be oxidized into heating furnace tube.
2nd, the shield gas endless tube and protective gas annular branch pipe spout that the utility model discharging opening is set, smoke discharging pipe is arranged
The tail gas gone out or other reducibility gas are passed through protective gas import, have completely cut off outside air and have entered heating-furnace from discharging opening
Pipe, effectively prevent the surface oxidation phenomenon of heated material.
3rd, when heating steel ingot billet/part blank, its surface does not aoxidize heating furnace of the present utility model, and structure letter
It is single, relatively low, safety and stability is invested, workable, continuous operation, heating internal and external temperature are uniform, energy-saving, emission-reducing, environment friendly.
