To solve above technical problem, the technical solution of the utility model is to use a kind of controllable temperature industrial furnace, and it is wrapped
Include body of heater and fire door, it is characterised in that：The body of heater fixes on the ground, and ground corresponding to the furnace chamber of body of heater is provided with melt pit,
Lowering or hoisting gear is fixed with melt pit, the bottom that fire door is arranged on body of heater is fixed on lowering or hoisting gear, and rollway is fixed or liftable
Be arranged on by lowering or hoisting gear, be fixed with pusher cylinder on two walls of melt pit；The body of heater is by shell, heat-insulation layer and refractory layer group
Into being provided with cooling water pipe in heat-insulation layer, step bricks are fixedly connected with refractory layer, and resistance wire is placed in the stepped groove of step bricks.
When the rollway is fixedly installed on by lowering or hoisting gear, the level altitude of pusher cylinder is highly parallel with rollway,
And rollway is highly less than furnace bottom height.
Further, the rollway is liftable is arranged on by lowering or hoisting gear, and specially rollway is fixed on feed and risen
On falling unit, feed lowering or hoisting gear is fixed on melt pit.
Further, the boss of furnace bottom doorframe can be embedded in by being provided with the fire door, and the periphery of boss is provided with ring
The insulation quilt of shape, improve the sealing thermal insulation effect of fire door.
Further, the resistance wire is processed helically shaped using nickel chromium triangle high-temperature alloy.
Further, the furnace roof cross section of the body of heater is arc, avoids dust from being deposited in furnace roof, influences electric furnace heating effect
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.
In summary, the utility model has the advantages of applied widely, easy to use, temperature control effect is good, energy-conserving and environment-protective.
