Embodiment

As illustrated in fig. 1 and 2; A kind of quartzy material sealing temperature determinator of the utility model; The stove plug 7 that comprises furnace shell 2 and be arranged on furnace shell 2 both sides is established corundum ceramic pipe 5 in the said stove plug 7, the accurate thermopair 6 of bidding in the said corundum ceramic pipe 5; Said standard couple 6 is connected with stove plug 7 outer potential difference meters 8; Offer temperature control thermocouple hole 10 on said corundum ceramic pipe 5 and the furnace shell 2 one distolateral walls, in said temperature control thermocouple hole 10, be provided with the temperature control thermopair, said temperature control thermopair is connected with furnace shell 2 outer temperature controllers 9; Being wound with platinum wire 4 and platinum wire 4 on the outer wall of said corundum ceramic pipe 5 successively decreases to a side along corundum ceramic pipe 5 along its density of temperature control thermocouple hole 10 coilings; Also be provided with insulation material 3 between said furnace shell 2 and the corundum ceramic pipe 5.

The combustion chamber of present embodiment is made with corundum ceramic pipe 5, and the outside forms with platinum wire 4 coilings; The length of corundum ceramic pipe 5 is 1000mm, and external diameter is 50mm, and wall thickness is 5mm.Thermograde is to form by being wound on corundum ceramic pipe 5 outer platinum wire 4 density degree differences, and closeer near platinum wire 4 coilings at place, temperature-control heat couple 1 hole, thermograde is less; Coiling near corundum ceramic pipe 5 two ends platinum wires 4 is more and more thinner, and thermograde is also increasing.

The course of work of this instance: before using, the reply thermograde is demarcated, in the hope of the curve of temperature in furnace superintendent and the stove; Method is: furnace temperature is risen to temperature required; Be incubated 4 hours, insert standard couple 6 to body of heater B end from body of heater A end then, standard couple 6 was stopped after 5 minutes; Record the temperature value of this point with potential difference meter 8; Successively standard couple 6 is begun to pull out 1cm to the A end by the B end then at every turn, on potential difference meter 8, read temperature value again, thereby obtain the relation of each point temperature in furnace superintendent and the stove.With the furnace superintendent is horizontal ordinate, and temperature is an ordinate, draws temperature gradient curve in the stove in 1: 1 ratio.

Open temperature controller 9 switches and heat up, reached after the maximum temperature insulation 4 hours, demarcate the thermograde in the temperature gradient furnace stove then to temperature gradient furnace; Open stove plug 7, the sample that the length of side is no less than 30mm pushes in the temperature gradient furnace along the A end of temperature gradient furnace one by one, and the style that pushes is closely arranged along the temperature gradient furnace length direction; Heat up according to the temperature of setting, heating rate and maximum temperature are through temperature controller 9 controls; When temperature gradient furnace rises to maximum temperature, be incubated powered-down after 30 minutes, open stove plug 7, let style cool off fast; After the style cooling, take out the style unit, measure one by one by the flow diameter of the article of quartzy material on the envelope style along low-temperature end, as finding out the corresponding temperature in each style center among Fig. 2; In conjunction with the article mobile requirement of different product to the quartzy material of sealing-in, find out the temperature under the corresponding flow diameter, be sealing temperature.

The measurement range of the utility model is by room temperature to 1350 degree, and optimum measurement scope 400 degree require 400 degree enough little to 1000 degree thermogrades, and the length of temperature gradient furnace are not less than 1000mm to 1350 degree.

More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
