Description

A kind of controllable temperature industrial furnace
Technical field
It the utility model is related to a kind of industrial furnace, and in particular to a kind of controllable temperature industrial furnace, belong to industrial electrical heating Engineering device technique field.
Background technology
Industrial furnace is a kind of plant equipment for being used to heat, and it produces heat to realize the exchange of electric heating, extensively by electric energy In the general hot-working industry applied to metal, carried out in an oxidizing atmosphere for metal part normalizing, annealing, quenching and it is other plus Heat is used.Electric furnace leans on Resistant heating, because resistance wire can not be cooled down quickly so heating temperature when needing to adjust temperature Degree also wants the regular hour slowly to turn cold, and in-furnace temperature control effect is bad, needs the technique that quickly cools down for some Such electric furnace heating has certain limitation, and existing electric furnace is mostly side opening structure, and opening the door can all make each time Heat in stove largely scatters and disappears, and heat utilization efficiency is low, and energy resource consumption is big.And resistance wire is fixed by putting a brick more, put a brick due to Resistance wire is directly supported, it is necessary to bear higher temperature and there is higher creep strength, thermal conductivity ratio step bricks are big, thermal resistance Smaller than step bricks, big by step bricks by putting the heat ratio that a brick spreads out of to furnace outer wall, heat loss phenomenon is serious, energy resource consumption Greatly.
Utility model content
In view of this, in view of the shortcomings of the prior art, the utility model provides a kind of applied widely, easy to use, control Temp effect is good, the controllable temperature industrial furnace of energy-conserving and environment-protective.
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.

Embodiment
In order that those skilled in the art more fully understands the technical solution of the utility model, below in conjunction with the accompanying drawings with it is excellent Selecting embodiment, the utility model is described in further detail.It should be pointed out that following preferred embodiments should not regard For that should be defined to limitation of the present utility model, the scope of protection of the utility model by claim limited range.For For those skilled in the art, do not departing from spirit and scope of the present utility model, can also make some Improvements and modifications, these improvements and modifications also should be regarded as the scope of protection of the utility model.
Referring to Fig. 1, Fig. 2, the utility model provides a kind of controllable temperature industrial furnace, and it includes body of heater 1 and fire door 2, institute Body of heater 1 to be stated to fix on the ground, ground corresponding to the furnace chamber of body of heater 1 is provided with melt pit 3, and lowering or hoisting gear 4 is fixed with melt pit 3, The bottom that fire door 2 is arranged on body of heater 1 is fixed on lowering or hoisting gear 4, and rollway 5 is liftable to be arranged on by lowering or hoisting gear 4, specifically It is fixed on for rollway 5 on feed lowering or hoisting gear 501, feed lowering or hoisting gear 501 is fixed on melt pit 3, solid on two walls of melt pit 3 Surely there are pusher cylinder 6 and pusher cylinder 7;The body of heater 1 is made up of shell 101, heat-insulation layer 102 and refractory layer 103, heat-insulation layer Cooling water pipe 8 is provided with 102, step bricks 9 are fixedly connected with refractory layer 103, and resistance wire 10 is placed in the stepped groove of step bricks 9 In 901.Resistance wire 10 is helically shaped using the processing of nickel chromium triangle high-temperature alloy.
