Description
Affiliated technical field:
The utility model relates to metallurgical class industrial furnace design field, is specifically related to a kind of novel energy-conserving resistance furnace.
Background technology:
Resistance furnace generally is used for various metal material heat treatments to be produced, and as quenching, annealing, normalizing, tempering and thermo-chemical treatment etc., is present domestic and international application hot-treatment heating equipment the most widely.Existing resistance furnace, furnace lining all adopts bit brick to build by laying bricks or stones and forms, have following problems in actual use: it is fragile 1, to put a brick: load put resistance wire put a brick to the distance of drop-bottom generally between the 80-120 millimeter, because it is small-sized to put a brick, thick 20 millimeters, wide 50 millimeters, thus ruptured because of colliding often at the turnover workpiece, behind the 3-4 piece that breaks resistance wire promptly sagging, disconnect and to break down; 2, the thermal efficiency is low, and power consumption is big: drop-bottom is supported by the high heavy brick of 2-3 row thermal conductivity, and resistance wire is placed on putting greatly on the brick between the heavy brick, and brickwork joint is many, and heat loss is big; The furnace lining material composite thermal insulation is good, but radiance is low, and it is slow to cause stove to heat up, and has increased non-cutting time, wastes energy; Simultaneously resistance wire becomes fragile easily brokenly because of self temperature is too high, overheated, and fault rate increases; 3, maintenance cost height: the maintenance intervals time is short, and overall maintenance cost is increased.
Summary of the invention:
The purpose of this utility model is the problem that a brick is fragile, the thermal efficiency is low and maintenance cost is high of putting that will solve the prior art existence.
For achieving the above object, technical solution of the present utility model is: a kind of novel energy-conserving resistance furnace, comprise that furnace roof 1, furnace wall 2 and furnace bottom put brick 5, and its special character is that 2 inboards, described furnace wall are provided with puts a boss 3.
The described boss 3 of putting is a plurality of, and a plurality of boss 3 of putting are distributed in 2 inboards, furnace wall, its longitudinal section undulate.This waveform can make the radiating surface of stove inner surface increase, and improves the thermal efficiency.
A side is provided with cavity in 2 bottoms, described furnace wall, the stove, its interior chimeric anti-collision block 4 that has, and the side of this anti-collision block 4 in stove is the plane.
Above-mentioned each put a boss 3 lower surfaces in body of heater, its radiation direction can make stove quick heating and evenly in body of heater like this.
Above-mentioned furnace wall 2 is large-sized several pieces, and described furnace bottom is put brick 5 and is monoblock or large-sized several piece, and is convenient when mounted and can avoid too much slit to cause heat loss.
Above-mentioned furnace roof 1 and furnace wall 2 are integrated poured prefabricated sections, and the outer side of stove is a porous material, and a side is a high-strength material in its stove.The inboard of furnace roof 1 and furnace wall 2 has certain intensity like this, and the outside then has heat-insulating property preferably.
Above-mentioned anti-collision block 4 is high-strength materials, and is not fragile when workpiece clashes into it.
Above-mentioned anti-collision block 4 is integrated poured prefabricated sections, and the height on the plane of described anti-collision block 4 is between the 200-240 millimeter, and this level is for deciding with existing resistance furnace consistent size.
In above-mentioned anti-collision block 4 stoves top on the plane of a side setting also can be provided with furnace wall 2 on put that a boss 3 engages continuously put a boss 3.
An above-mentioned boss 3 surfaces of putting are brushed with Cr
2O
3And Fe
2O
3It is the infrared radiation ceramic coating of main material.
Compared with prior art, the utility model has the advantages that:
1, long service life:, be not afraid of collision, so resistance furnace disposable service life can be greater than 3 years because anti-collision block adopts planar structure;
2, thermal efficiency height, power consumption are little: owing to adopt the assembly unit of large scale structure, the slit is few, and a plurality of waveform of boss formation of putting make its radiating surface increase, the radiating surface below it in stove in the stove, therefore the stove programming rate improves more than 15%, heat loss reduces more than 8%, made full use of heat energy, cut the waste;
3, simple in structure, make easy to maintenance: the utility model, overlap joint modular assembled, thereby simple in structure by the bulk preformed bricks, make easy to maintenance;
4, applied widely: be applicable to the transformation and the new stove manufacturing of existing high, medium and low incubator formula, well formula, bench vehicle type electrical resistance furnace, its burner hearth usable floor area and cost are all basic identical with prior art.
