Abstract
The utility model relates to an amorphous electric heating body heating furnace improved from a high-temperature electric resistance furnace, composed of a furnace shell (1), bolts (2), a furnace chamber (4), insulation materials (2), fireproofing materials (3), a temperature measurement couple (7), a furnace cover (8), etc. The utility model characterized in that a powder electric heating element (1) is the heating element of the heating furnace, and is arranged between the furnace chamber (4) and the fireproofing materials (3). Current enters the powder electric heating element from graphite electrodes (17), (19) and carbon seal rings (12), (10), and then the current generates heat and the temperature rises. The utility model has the advantages that the heating element changes with the shape of the furnace chamber and clings to the outer wall of the furnace chamber, the heat efficiency is high, the temperature rise is rapid, the time is short, the power consumption is saved, and the cost is reduced.
Description
The utility model relates to the improvement to high-temperature electric resistance furnace.
Present domestic and international employed high-temperature electric resistance furnace; the general non-metal electric heating body that uses can only use 1700 ℃ in air, high again temperature must be used under vacuum or protective atmosphere; and cost is very high, and this has just limited high-temperature electric resistance furnace application in a wider context.
The purpose of this utility model provide one that under any atmosphere, can both use, cost is very low, and the unrestricted ultrahigh temperature heating furnace of the shape of burner hearth.
The purpose of this utility model realizes by following measure, and furnace shell end cap (19) is fixed on the left side of furnace shell (1) by bolt (20), and the first layer in the furnace shell (1) is lagging material (2); The second layer is refractory materials (3); Trilaminar two ends are sealing lagging material (5), (18), the middle part is powder electric heating element (11), between powder electric heating element and sealing lagging material is graphite-seal ring (10), (12), and Graphite Electrodes (9), (17) are passed the furnace shell two ends respectively and are connected with graphite-seal ring (10), (12) with sealing lagging material (5), (18) back; The 4th layer is burner hearth (4), the burner hearth two ends are respectively bell (6), (15), and bell (6) top is installed with thermometric galvanic couple (7), and stretch to the top of burner hearth middle part crucible, bell (6) bottom is installed with escape pipe (8), and bell (15) top is installed with inlet pipe (16).
Furnace shell (1) and burner hearth (4) can be horizontal, also can be vertical.The material of burner hearth is a corundum, also can be ZrO
2The shape of burner hearth can be circular, square, or other arbitrary shapes.The material of powder electric heating element (11) can be a Graphite Powder 99, also can be the SiC powder, or these two kinds of mixtures of material.
The utility model compared with the prior art because the electrical heating element of this process furnace is the powder electric heating element, is close to hearth outer wall, make electric heating element and burner hearth transmission of heat by contact, so heat transfer efficiency height, quick heating has shortened heat-up time, save the electric weight that consumes, reduced cost.
Description of drawings is as follows:
Fig. 1 is the structural profile synoptic diagram of unformed electric heating element process furnace.
Fig. 2 removes side-view behind left side bell and the furnace shell end cap for Fig. 1.
The 1-furnace shell, 2-lagging material, 3-refractory materials, 4-burner hearth, 5-seals lagging material, 6-bell, 7-thermometric galvanic couple, 8-escape pipe, the 9-Graphite Electrodes, 10-graphite-seal ring, 11-powder electric heating element, the 12-graphite-seal ring, 13-crucible, 14-sample, the 15-bell, 16-inlet pipe, 17-Graphite Electrodes, 18-seals lagging material, 19-furnace shell end cap, 20-bolt.
The utility model will be further described in conjunction with the accompanying drawings, place furnace shell (1) vertically left end up, put into refractory materials (3) and burner hearth (4), the lagging material (2) of between furnace shell and refractory materials, packing into, between refractory materials and burner hearth, put into sealing lagging material (5) earlier, the graphite-seal ring (10) that will be connected with Graphite Electrodes (9) is then packed into, and make Graphite Electrodes pass the end of sealing lagging material (5) and furnace shell (1), again powder electric heating element (11) is inserted, then put into graphite-seal ring (12), the Graphite Electrodes (17) that makes its connection up, reinstall sealing lagging material (18), at last furnace shell end cap (19) is fixed on the furnace shell by bolt (20), and makes Graphite Electrodes (17) pass the furnace shell end cap.Then furnace shell (1) is just put, the central authorities that the crucible (13) that is heated sample (14) is put into burner hearth will be housed again, then the bell (6) that is installed with thermometric galvanic couple (7) and escape pipe (8) is filled in the right-hand member of burner hearth (4), and make thermometric galvanic couple (7) above crucible, escape pipe (8) is in the bottom of bell (6), again the bell that inlet pipe (16) are housed (15) is filled in the left end of burner hearth (4), made inlet pipe (16), at last Graphite Electrodes is connected with supply lead on the top of bell (15).Switch on after feeding shielding gas, treat that furnace temperature rises to outage cooling behind the preset temperature, stop ventilation when reducing to normal temperature, open bell (6), (15), take out crucible and sample.
