Abstract
It is a kind of burn heater furnace be related to burn Elema heater furnace.Mainly to solve the crystallization degree that the existing furnace for burning Elema heater passes through power control silicon carbide, leads to the problem that product qualification rate is low and design.It includes furnace body, and furnace body is rack-mount, and the both ends of heating graphite pipe are connect with furnace body, and the end of heating graphite pipe is equipped with copper electrode, has protective case outside heating graphite pipe, and carbon black, the apertured on protective case and furnace body are filled between furnace body and protective case；Graphite-pipe rear end is enclosed construction, and graphite-pipe is extend into furnace body by outside through the hole on furnace body, and its rear end is fixed on the hole wall of protective case；White steel cylinder is cased with outside graphite-pipe outside furnace body, the rear end of white steel cylinder is fixed on furnace body, and graphite-pipe is equipped with nitrogen inlet, also is provided with nitrogen inlet on white steel cylinder, front in graphite-pipe is equipped with quartz glass eyeglass, and infrared radiation thermometer is mounted on the front of white steel cylinder.Advantage is the heater qualification rate height burnt.
Description
Technical field:
The utility model relates to a kind of furnaces for burning Elema heater.
Background technique:
At present when burning Elema heater with the furnace for burning Elema heater, using power control and observe outside heater
See, section determines the crystallization degree of silicon carbide, determine sintering effect.It is relatively low that this method burns the fever temperature come sometimes
Or it is higher it is necessary to power is increased or decreased.In addition with the increase of firing time, carbon pipe uses the extension of time, carbon
The wall thickness of tube wall is also constantly thinning, because in addition to oxidation, other than silication, to the mill of tube wall when passing through heat-generating pipe there are also graphite boat
Damage.If be burnt into again with the same power after the tube wall that generates heat is thinning, heater stick can be burnt, because of tube wall temperature after tube wall is thinning
Degree increases, therefore needs to drop some power, and it is suitable to drop how much power, just can only be by rule of thumb.Specifically silicon carbide at how many temperature
Start not knowing for crystallization, therefore product quality is extremely unstable, qualification rate is low, and waste is big.
Summary of the invention:
The technical problem to be solved by the utility model is to provide a kind of heater of firing is high-quality, the high burning of qualification rate
Heater furnace.
Above-mentioned purpose is achieved in that it includes furnace body, and furnace body is rack-mount, and heating graphite is equipped in furnace body
Pipe, the both ends of heating graphite pipe connects with furnace body, and the end of heating graphite pipe is equipped with copper electrode, heating graphite pipe outside equipped with by
The protective case of graphite production, is filled with carbon black, the apertured on protective case and furnace body, protective case and furnace body between furnace body and protective case
On hole all on the same line；
It further include hollow graphite-pipe, the rear end of graphite-pipe is enclosed construction, and graphite-pipe is stretched by outside through the hole on furnace body
Enter into furnace body, and its rear end is fixed on the hole wall of protective case；It is cased with white steel cylinder outside graphite-pipe outside furnace body,
The rear end of white steel cylinder is fixed on furnace body, and graphite-pipe is equipped with nitrogen inlet, is also set on white steel cylinder corresponding with nitrogen inlet
There is nitrogen inlet, the front in graphite-pipe is equipped with quartz glass eyeglass, and infrared radiation thermometer is mounted on the front of white steel cylinder, infrared
Temperature measurer is located at the front of quartz glass eyeglass.The graphite-pipe is high-density graphite pipe.It constantly to be blown in graphite-pipe when work
Enter nitrogen, smog is prevented to be attached on quartz glass eyeglass, guarantees the accuracy of the temperature signal taken out.
Infrared radiation thermometer is connected with intelligent temperature control table with data line, and intelligent temperature control table is rack-mount.
The utility model has the advantages that: it is red since graphite-pipe is hollow, radiated IR energy after the heating of heating graphite pipe
Outer energy focuses on infrared radiation thermometer, switchs to for corresponding electric signal, which switchs to the temperature value of measured target through converting.Its
Accuracy is ± 2 DEG C, and accuracy is very high.
Determine that silicon carbide crystallization effect at 2450 DEG C is best through inspection information, power control is changed to temperature control by we
System, firing temperature is set in 2450 DEG C, regardless of heating tube burn how long, wall thickness is how many, firing temperature be all it is constant,
Even if firing power changes, sintering effect is not hindered yet.With the present apparatus burn come heater is high-quality, stable, qualification rate is high.
Detailed description of the invention:
Fig. 1 is the schematic view of the front view of the utility model；
Fig. 2 is the right side structural representation of the utility model.
Specific embodiment:
Referring to Figures 1 and 2, it includes furnace body 1, and furnace body is mounted on bracket 2, and heating graphite pipe 3, graphite are equipped in furnace body
The both ends of heat-generating pipe are connect with furnace body, and the end of heating graphite pipe is equipped with copper electrode 4, are equipped with outside heating graphite pipe by graphite system
The protective case 5 of work is filled with carbon black 6, the apertured on protective case and furnace body, on protective case and furnace body between furnace body and protective case
Hole is all on the same line；
It further include hollow graphite-pipe 7, the rear end of graphite-pipe is enclosed construction, and graphite-pipe is stretched by outside through the hole on furnace body
Enter into furnace body, and its rear end is fixed on the hole wall of protective case；White steel cylinder is cased with outside graphite-pipe outside furnace body
8, the rear end of white steel cylinder is fixed on furnace body, and graphite-pipe is equipped with nitrogen inlet 9, on white steel cylinder corresponding with nitrogen inlet
Equipped with nitrogen inlet, the front in graphite-pipe is equipped with quartz glass eyeglass 10, before infrared radiation thermometer 11 is mounted on white steel cylinder
Portion, infrared radiation thermometer are located at the front of quartz glass eyeglass.The graphite-pipe is high-density graphite pipe.It is wanted in graphite-pipe when work
It is constantly blown into nitrogen, smog is prevented to be attached on quartz glass eyeglass, guarantees the accuracy of the temperature signal taken out.
Infrared radiation thermometer is connected with intelligent temperature control table 12 with data line, and intelligent temperature control table is rack-mount.
