Description
Technical field
The utility model relates to electrical and electronic technology field, particularly relates to a kind of workpiece resistance furnace.
Background technology
Resistance furnace utilizes electric current to make in stove heating or heat medium heating, thus the industrial furnace to workpiece or heating material.Resistance furnace in mechanical industry for the drying etc. of heating before metal forging, metal heat treatmet heating, soldering, powder metallurgy sintered, glass ceramics roasting and annealing, low-melting-point metal fusing, sand mold and paint film.The electric furnace that resistance furnace is is thermal source with electric current by the Joule heat that conductor produces.
Resistance furnace take electricity as thermal source, is heat energy, heats in stove to metal by heating by electric energy conversion.Resistance furnace and flame ratio, the thermal efficiency is high, and can reach 50-80 ℅, thermal regulation easily controls, and working condition is good, and converter life is long, be applicable to the heating requiring tighter workpiece, but power consumption costly.By heat transfer type, resistance furnace is divided into radiant type resistance furnace and convection type resistance furnace.Radiant type resistance furnace is based on radiant heat transfer, and convection heat transfer' heat-transfer by convection effect is less; Convection type resistance furnace, based on convection heat transfer' heat-transfer by convection, is commonly referred to air circulation resistance furnace, heats by hot-air, and furnace temperature is many lower than 650 DEG C.By electric heating producing method, resistance furnace is divided into directly heating and indirect two kinds.
Common resistance furnace only has three heating tubes in bottom, and firing rate is comparatively slow, affect the heating effect of workpiece, simultaneously and without heat-barrier material, close deficiency, cause effect of heat insulation not to be fine.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of workpiece resistance furnace.
The utility model is achieved through the following technical solutions:
A kind of workpiece resistance furnace, comprise resistance furnace housing, plate placed by the workpiece that described resistance furnace enclosure interior is provided with T-shaped structure, the sidewall of described resistance furnace housing is provided with thermal insulation layer, described thermal insulation layer is pasted onto on the sidewall of resistance furnace housing, described resistance furnace housing longitudinal cross-section is polygonized structure, described resistance furnace housing two inclined sides are provided with the first heating tube, upper side is provided with the second heating tube, two vertical sides are provided with the 3rd heating tube, and between described first heating tube, the second heating tube from the 3rd heating tube, length is different.
As optimal technical scheme of the present utility model, the thickness of described thermal insulation layer is 10mm ~ 20mm.
As optimal technical scheme of the present utility model, described first heating tube, the second heating tube are fixedly connected with between the sidewall of resistance furnace housing with the 3rd heating tube.
As optimal technical scheme of the present utility model, be arranged symmetrically with between described first heating tube, the 3rd heating tube.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, the utility model is by arranging the first heating tube, the second heating tube and the 3rd heating tube, can improve under the effect of the first heating tube, the second heating tube and the 3rd heating tube like this and add heat, the efficiency of heating surface improves greatly; By arranging thermal insulation layer, such thermal insulation layer can reduce the loss of heat, achieves energy-conservation.
