Description
Technical field
The utility model relates to a kind of high temperature cabinet-type electric furnace of energy-efficient, environmental protection, is applicable to burning till of Inorganic Non-metallic Materials such as pottery, glass, and the high-temperature heat treatment of metal material etc.
Background technology
Industry and scientific research are meant generally that with the high temperature cabinet-type electric furnace operating temperature is 1000 ~ 2000 ℃ a batch (-type) electric furnace, are important experiment and the production equipments that is widely used in various fields such as pottery, glass, powder metallurgy, chemical industry, machinery, the energy.The high temperature cabinet-type electric furnace is to be that thermal source comes heated parts with electric current by the heat that conductor was produced, and mainly is made up of body of heater, heater, several major parts of observing and controlling temperature system, and its body of heater generally then is to be made of burner hearth, thermal insulation layer and metal shell.
Existing high temperature cabinet-type electric furnace can be divided into two big classes by furnace binding and material.One class is the electric furnace of being made by common high-temperature refractory, is characterized in that burner hearth made by the high-temperature refractory of heavy, as aluminous refractory, corundum or corundum-mullite fire resistant materials, and aluminium oxide or zirconia hollow ball refractory material etc.; Its thermal insulation layer adopts lightweight refracrory mostly, as the high-alumina lightening brick of porous or light weight fireclay brick etc.The advantage of this type of common high temperature cabinet-type electric furnace be simple in structure, serviceability temperature is high (reaching as high as ~ 1800 ℃), manufacturing cost is lower, but its maximum shortcoming is: the material thermal capacitance is big and body of heater is thicker, so amount of stored heat is very high; The thermal conductivity factor height, thereby heat-proof quality is not ideal enough.Because the loss of accumulation of heat and heat radiation cause the energy consumption of sintering process very high, and warming and cooling rate is slow, can't satisfy experiment or production technological requirement to rapid temperature rise and drop.
Another kind of high temperature cabinet-type electric furnace is the full refractory fibre stove that occurs in recent years, and its body of heater is all made by refractory fibrous material.The structure of this electric furnace is normally made the monoblock type burner hearth by the high high-temperature refractory fiber material of refractoriness, by the relatively low refractory fibrous material of refractoriness as thermal insulation layer.This full refractory fibre stove is because good heat-insulation effect, amount of stored heat are little, thus have good energy-saving effect and good heating and cooling handling.But also there is following outstanding shortcoming in the full refractory fibre stove: at first, the dust of refractory fibre can produce harm to respiratory system after being sucked by the people, and might be carcinogenic.After its at high temperature long-term use, can follow the string gradually, thereby the fracture efflorescence produces fibre dust.Secondly, still there is a big difference for the more traditional non-fiber-like refractory material of refractoriness of refractory fibre at present, its maximum operation (service) temperature is generally limited to below 1500 ℃, also be no more than 1700 ℃ the extremely expensive superhigh temperature refractory fibre (as high purity aluminium oxide, Zirconium oxide fibre) of cost, can't satisfy and produce and the widespread demand of experiment.In addition, another shortcoming of full refractory fibre high temperature cabinet-type electric furnace is that burner hearth intensity is very low, easily in use by scratch and wearing and tearing such as saggar, crucible and fire tongs; The material that thing volatilizes is burnt in the easier absorption of the burner hearth of the general heavy refractory material of its cellulosic burner hearth, causes high temperature to melt erosion, and therefore its life-span can significantly shorten.
