Description
Technical field
The utility model relates to Inorganic Non-metallic Materials metallurgical performance experimental rig, refers to a kind of fast cooling test heating furnace particularly.
Background technology
At present, test generally is to be placed on sample in the reactor to the metallurgical performance of Inorganic Non-metallic Materials, and then in heating furnace, heats, and takes out sample subsequently, sample is lowered the temperature analyze after the cooling again.Existing reactors can be divided into metallic reactors and corundum reactor.
When for example coke carries out the reactivity test to Inorganic Non-metallic Materials; With reference to the explanation of GB/T4000 " coke reactivity and post reaction strength test method " in test procedure: coke 1100 ℃ with carbon dioxide reaction after 2 hours; Can rapidly metallic reactors be taken out from electric furnace; Be placed on and continue logical nitrogen on the support, coke is cooled off.So the purpose of operation is in order to add the cooling of coke specimen behind the fast response, to shorten the entire test required time, to realize the purpose of report test data on duty.
When using metallic reactors, be under when metallic reactors is taken out from heating furnace near 1000 ℃ the condition of high temperature, so operation, easy burn and scald people exists very large potential safety hazard.After simultaneously under the condition of high temperature, proposing metallic reactors outside the stove, the metallic reactors oxidation in the stove outer air is stronger, is prone to trachoma, produces decortication, causes shorten the service life of metallic reactors.
When using the corundum reactor; Because the performance of corundum material, the corundum reactor can not take out stove and carry out chilling outward, otherwise the corundum reactor is prone to crack; Therefore coke 1100 ℃ with carbon dioxide reaction after 2 hours; After the heating furnace outage is that nature is cooled to room temperature, waits for second day and takes out corundum reactor, report test result again.Because the corundum reactor is than several times of metallic reactors long service life, serviceability is superior, and the corundum reactor cost is less than metallic reactors cost 1/3, thereby the corundum reactor uses in the report test result's on duty project of not being eager in a large number.
In test heating process, heating-furnace wall surface temperature reaches about 150 ℃ in addition, and the furnace wall heat radiation causes the process of the test power consumption high; Also there is the potential safety hazard that is prone to scald the people in furnace wall surface temperature height simultaneously.
Therefore; To existing test heating furnace in process of the test, exist potential safety hazard, metallic reactors service life short, furnace wall temperature is too high in long, the test of heating furnace nature temperature fall time when using the corundum reactor, the test power consumption is too high, the defective that can not report experimental result fast, be necessary existing test heating furnace is improved.
Summary of the invention
The purpose of the utility model is exactly to solve the deficiency that the above-mentioned background technology exists, and a kind of fast cooling test heating furnace is provided.
The technical scheme of the utility model is: a kind of fast cooling test heating furnace; Comprise furnace shell; The inboard of said furnace shell is provided with the furnace wall refractory insulating layer, and the bottom of said furnace shell is provided with furnace bottom refractory brick heat-insulation layer, and the top of said furnace shell is provided with fire door refractory brick heat-insulation layer; Said fire door refractory brick heat-insulation layer is provided with the heating element heater that extend in the furnace shell inner chamber; In said furnace shell, be provided with the water-cooled interlayer, the lower end of said water-cooled interlayer is respectively arranged with water intaking valve and draining valve, and the upper end of said water-cooled interlayer is provided with the spilling water valve.
Preferably, said furnace shell and water-cooled interlayer thereof adopt stainless steel component to be welded.
Further, said furnace bottom refractory brick heat-insulation layer is to be suitable for the monoblock type refractory brick heat-insulation layer of metallic reactors heating or the perforated refractory brick heat-insulation layer of corundum reactor heating.
The operation principle of the utility model is such:
1, before to the heating furnace feeding temperature-raising, close the water intaking valve and the top overflow valve of water-cooled interlayer bottom, open the bottom discharge valve, the interior aqueous vapor of water-cooled interlayer is discharged fully, this moment, the water-cooled interlayer became air heat-insulation layer.In the test heating process, can completely cut off the heat of furnace wall refractory brick heat-insulation layer, reach the appearance temperature effect that reduces the heating furnace furnace shell, furnace shell appearance temperature can be reduced to about 60 ℃ in the test heating process.
2, after test was accomplished, the heating furnace outage stopped heating, and open the cooling sea water inlet valve and the top spilling water valve of interlayer bottom this moment, closes the bottom discharge valve.This moment, the furnace wall interlayer converted the cooling water wall to, and the low-temperature cooling water that constantly gets into through the bottom absorbs the heat from furnace wall refractory brick heat-insulation layer, and hot water flows out from the spilling water valve port on top, takes away the stove heat, reaches the purpose of quick reduction furnace temperature.
The utility model is through the water-cooled interlayer is set in the furnace shell of heating furnace; And be respectively arranged with water intaking valve and draining valve in the lower end of water-cooled interlayer; Be provided with the spilling water valve in the upper end of water-cooled interlayer; Can make metallic reactors at high temperature propose stove and lower the temperature outward, avoid this oxidation in air of metallic reactors, prolong metallic reactors service life; It can make the corundum reactor test reduce furnace fast, realizes report test result's on duty purpose, can reduce reactor cost consumption greatly again simultaneously.And the utility model can reduce below the furnace shell appearance temperature to 60 ℃, avoids the heating furnace furnace shell to be prone to scald people's potential safety hazard, and has the effect that reduces the test power consumption.
