Abstract
The utility model relates to a novel box electric resistance furnace, relating to the technical field of the heat treatment heating furnace. The utility model is composed of a furnace bottom seat, a furnace body, a furnace door, a furnace door lifting mechanism, heating resistance wires arranged in the furnace body, a heat insulating material and a trolley moving along a guiding rail. The utility model is characterized in that the heat-insulating and heating part on the trolley frame is that a heat-insulating layer of the aluminium silicate fibre is additionally arranged between a brickwork and the trolley frame, and a furnace laminate for workpieces placing on the trolley top is composed of at least two steel plates with ribs. Besides, each plate is provided with at least one vent hole for the hot air. The utility model has the advantages of favorable heat insulating performance, sufficient heat flux, uniform furnace temperature, good workpiece quality, energy saving and high heat efficiency.
Description
The utility model is a kind of novel chamber type electric resistance furnace that heating or thermal treatment heating are given in the precise casting mould shell roasting that is used for, and relates to the process furnace technical field.
Existing chamber type electric resistance furnace is by resistive heater that is provided with in furnace base, body of heater, fire door, fire door hoisting appliance, the body of heater and lagging material and can be formed along the dolly that guide rail moves.The mobile of dolly is to be rotated by step down gear drive dolly axletree by electric motor to realize in general, the heat resisting brick masonry is set on the dolly, on this brick structures, to lay resistive heater again, from the bottom workpiece is heated, heated object just is in three heating like this, add the furnace roof reverberation more just for the four sides heating status, be heated evenly.But existing chamber type electric resistance furnace since on its body of heater and the dolly all with heat-stable brick structures as lagging material, because brick structures itself is by many brick one-tenth, there is the breathable slot centre, the insulation capacity of heat resisting brick itself can't be comparable with some novel materials simultaneously, so the thermo-efficiency of chamber type electric resistance furnace is not ideal enough.Be not have foraminous owing to placement on the existing dolly is subjected to the stove laminate of heated work pieces in addition, when so excessive or heat-up time is long when resistance wire heating current on the dolly brick structures, drop-bottom can make its heat radiation unhappy its covering, so can make the resistive heater scaling loss on the car.
The purpose of this utility model is to improve existing chamber type electric resistance furnace, employing improves the insulation heat insulating part of dolly and the structure of dolly top drop-bottom makes stove have higher thermo-efficiency and hot uniformity coefficient, thereby the saving electric energy is boosted productivity, and improves workpiece quality.
Chamber type electric resistance furnace of the present utility model is by furnace base, body of heater, fire door, the fire door hoisting appliance, the resistive heater and the lagging material that are provided with in the body of heater, and can form along the dolly that guide rail moves, described dolly comprises by electric motor, axle A and two motion-work wheels that are installed on the A of retarding mechanism and drive thereof, two follow-up pulleys, the axle dolly that B formed of device follow-up pulley moves partly, be loaded on an A, the vehicle frame part of forming by channel-section steel and steel plate on the B, with the heat resisting brick brick structures and the heat tracing part that is laid in the resistive heater composition on the brick structures that are installed on the vehicle frame, and the storing workpiece part that is arranged at the vertical drop-bottom of brick structures.The thermal insulation layer of clogging one deck aluminum silicate fiber in the frame that partly steel plate and steel plate all around thereof are formed bottom dolly of the heat tracing in the described car frame earlier that is characterised in that of the present utility model, brick structures (with resistive heater on it) places on this thermal insulation layer and forms then, described drop-bottom is by be made of the interface that overlaps mutually between promising plate on every block of plate of its composition and the hole of at least one logical hot gas at least two blocks of plates that have muscle.
The utility model has been clogged the good aluminum silicate fiber layer of one deck insulation heat-insulating property because of the dolly bottom, make the heat-insulating property of stove better, heat radiation is few, thermosteresis is little, and the thermo-efficiency height is simultaneously because of having the hole on its drop-bottom, the hot gas of the beneath resistive heater of drop-bottom can be passed by the hole, form air-flow, it is more even on the one hand furnace heat to be distributed, and can avoid the overheated scaling loss of heater strip on the other hand.New chamber type electric resistance furnace after improving by the design like this, good heat insulating, uniform heat distribution, the thermo-efficiency height, the workpiece quality that is heated is good, and the resistance wire scaling loss reduces.
