Abstract
The invention relates to a non-metal radiant tube. The non-metal radiant tube is characterized by being composed of quart glass. The non-metal radiant tube breaks traditional methods and uses the quart glass as materials for the radiant tube for the first time, so that good using performance is guaranteed and service life of the radiant tube can be prolonged.
Description
Technical field
The present invention relates to a kind of radiant tube, belong to the hot-treatment heating equipment technical field.
Background technology
Traditional metal radiation pipe after use a period of time, forms oxide skin at the radiant tube inwall because its metal material at high temperature can produce hot corrosion, and they are put aside to a certain degree peeling off.At this moment, in a single day the oxide skin of peeling off snap into the heater strip of radiant tube inside, can make metal radiation pipe and heater strip short circuit, and the high electric current of formation can puncture radiant tube, causes radiant tube and inner heater strip to be scrapped.In addition, in nitrogenize equipment, the metal radiation pipe is very large for the nitriding process impact, reason is that the outer surface of metal radiation pipe is equally also carrying out nitriding in process engineering, metal covering after the nitriding can accelerate the decomposition of ammonia, thereby the ammonia dissociation rate in the stove is progressively raise, reduce the nitriding speed of workpiece.General, in nitrogenize equipment, must carry out high temperature to the metal surface in the stove at set intervals and " move back nitrogen " and process, or radiant tube be extracted out carry out blasting treatment, remove the desalination layer on surface.
Summary of the invention
Because aforementioned not enough point of the prior art, the object of the invention is to service life of radiant tubes useful life.
To achieve these goals, technical scheme of the present invention is as follows:
A kind of radiant tube is characterized in that, is made by quartz glass.
Principle of the present invention is as follows: because quartzy fusing point is up to 1650 degrees centigrade, and has good chemical stability, so with respect to the metal radiation pipe, can reach higher serviceability temperature.And because its insulating properties, can not make electrical heating wire and the generation current short circuit of radiation tube wall and puncture radiant tube.In nitriding atmosphere, quartz material does not react with medium, can stablize the ammonia dissociation rate of oven cavity atmosphere, so that nitriding atmosphere is more controlled, and the useful life of greatly having improved radiant tube.In addition, by means of its good thermal stability, when rapid heat cycle, can not ftracture, make the fast cold technique of burner hearth become possibility yet.
The mode that the present invention breaks traditions is attempted adopting quartz glass first as the material of radiant tube, has goodish serviceability.Useful life of service life of radiant tubes greatly, and reduce maintenance work to nitrogenize radiation of equipment pipe.
Description of drawings
Fig. 1 is the radiant tube structural representation.
Embodiment
With reference to shown in Figure 1, be the radiant tube structural representation, described radiant tube 1 is made by quartz glass.
The quartz glass radiant tube is installed in the nitrogenize equipment, and after long-time the use, the surface does not form any nitration case, need not short-period extraction do maintenance, and whether extraction is watched intact when only needing annual equipment routine maintenance maintenance.In general firing equipment, the quartz glass radiant tube also can guarantee service time of growing.
In nitrogenize equipment, being compared as follows of two kinds of radiant tubes:
