Fruit.
Compared with prior art, side blow-on door is changed to furnace bottom opening structure by the utility model, and fire door is placed in into stove
Bottom, rise because when gases are heated, they expand, when opening workpiece in fire door replacing stove, hot gas moves upwards, from furnace bottom stove gate stream
The heat gone out is considerably less, and most heats are still stored in stove, and in-furnace temperature will not excessively decline, and is sent second batch workpiece
After entering in stove, stove heat temperature raising is given, in-furnace temperature will soon reach requirement, save heat energy, improve heat utilization efficiency, again
Shorten every time change workpiece after give furnace warming time, improve work efficiency, simultaneously because shortening warm-up time, workpiece enters
After entering in stove, temperature will soon be raised to the temperature needed for converted products, improve product quality.
A brick will be put on stove inwall and is changed to the less step bricks of thermal conductivity factor, resistance wire is placed in the stepped groove of step bricks,
Reduce heat loss caused by putting a brick, effectively save the energy.Cooling water pipe is set in heat-insulation layer, by adjusting cooling water
The flow and flow rate of cooling water in pipe, to coordinate the firing rate of resistive heater, realize the control to furnace chamber temperature.Observation
The setting of window facilitates observer to drive speculum in furnace chamber internal rotation by the rotation of observation window inner rotary shaft outside stove, so as to obtain
Obtain the good overall view in furnace chamber.
In summary, the utility model have applied widely, easy to use, temperature control effect is good, energy-conserving and environment-protective, can be at any time
To the advantages of material heating state is observed in furnace chamber.
