Abstract
The utility model discloses a trolley type heat treatment resistance furnace and aims to provide a trolley type heat treatment resistance furnace with a good heat-preserving effect and the capability of preventing burnout of resistance wires at the bottom of the furnace. The trolley type heat treatment resistance furnace comprises an external supporting frame, a furnace wall and a furnace bottom plate, wherein the resistance wires are arranged at the lower part of the furnace bottom plate; alumina silicate fibre cotton is arranged between the supporting frame and the furnace wall; a first thermocouple is arranged between the resistance wires at the lower part of the furnace bottom plate; and the thermocouple is connected with an external temperature display instrument. The furnace wall adopts asbestos plates instead of refractory bricks, so as to achieve a better heat-preserving effect; and the alumina silicate fibre cotton instead of pearlite and vermiculite powder is used for preserving heat, so that the weight of the furnace body is reduced and the heat-preserving performance of the electric furnace is improved. The thermocouple is arranged at the bottom of the furnace and can measure the actual heating temperature of the furnace bottom, so that the burnout of the resistance wires is avoided.
Description
Technical field
The utility model relates to a kind of HTFX, relates in particular to a kind of pallet car type resistor furnace for heat treatment.
Background technology
Bench vehicle type electrical resistance furnace is the energy-saving discontinuous running electric furnace of national standard; Be mainly used in thermal treatments such as Gao Ge, High Manganese Steel Casting annealing, tempering, timeliness, and the usefulness of grey cast iron, spheroidal graphite cast iron, roll, steel ball, grinder hammerhead, abrasion-proof backing block quenching, normalizing, tempering, annealing and various mechanical component thermal treatments.
Existing high temperature bench vehicle type electrical resistance furnace is provided with a thermometric at the top of body of heater and uses thermopair, because calorie spread makes progress; When body of heater heating reaches 1200 ℃ of use temperatures; And measure the temperature of coming and actual difference is arranged, the actual temperature of furnace bottom possibly reach more than 1350 ℃ considerably beyond 1200 ℃; Near the stagnation point of wire spiral fusing point, cause blowing of wire spiral easily.
And the furnace wall of resistance furnace commonly used is to be built into by refractory brick, and at the inboard fixed resistor silk of furnace wall and drop-bottom, heating can heat up after the energising.Above-mentioned electric furnace is because furnace wall is to be made up of refractory brick, and the heat insulation effect of refractory brick is not very good; And between furnace wall and outer support frame, adopting vermiculite power, perlite to be incubated usually, heat insulation effect is good inadequately.
The utility model content
To above-mentioned prior art, the technical problem that the utility model will solve provides a kind of high insulating effect, and prevents the pallet car type resistor furnace for heat treatment that the furnace bottom wire spiral burns out.
In order to solve the problems of the technologies described above; The utility model adopts following technical scheme: a kind of pallet car type resistor furnace for heat treatment; Comprise outer support frame, furnace wall, drop-bottom, the drop-bottom bottom is provided with wire spiral, is provided with aluminosilicate fiber cotton between support frame and the furnace wall; Be provided with first thermopair between the bottom wire spiral of drop-bottom, first thermopair is connected with the outside temperature display instrument.
Further, said furnace wall is made up of asbestos plate.
Further, the inwall of said furnace wall is provided with the far-infrared material coating.
Compared with prior art, the utlity model has following beneficial effect: furnace wall adopts asbestos plate, than adopting refractory brick to have better heat insulation effect; Adopt aluminum silicate fiber replacement perlite, vermiculite power to be incubated, both alleviated the weight of body of heater, improved the heat-insulating property of electric furnace simultaneously.Be provided with the actual heating temp that thermopair can be measured furnace bottom at furnace bottom, avoid burning out of wire spiral.
