Abstract
The utility model discloses a hard alloy pressure sintering furnace which comprises a furnace body (1) and furnace doors (2). The furnace doors (2) are arranged at the two ends of the furnace body (1), and two dewaxing openings (11) are symmetrically formed in the lower portion of the furnace body (1), and penetrate through the furnace body (1) and external space. The distance of the two dewaxing openings (11) and the adjacent furnace doors (2) is 1/5-1/3 of the length of the furnace body (1). Due to the fact that two dewaxing openings are symmetrically formed in the lower portion of the furnace body, on one hand, carbon potential is more even in the dewaxing process; on the other hand, the two dewaxing openings can be used alternately, and the furnace does not need to be closed immediately in case the dewaxing openings are blocked in the dewaxing process.
Description
Technical field
The utility model relates to sintering cemented carbide equipment technical field, more particularly, and particularly a kind of carbide alloy pressurized sintering furnace.
Background technology
Sintering cemented carbide is the critical process of CEMENTED CARBIDE PRODUCTION, and the final mass of product is had to conclusive effect.At present, the sintering process of carbide alloy has two developing direction, and the one, atmosphere is controlled sintering, and another is pressure sintering.
Wherein, adopt pressurized sintering furnace that carbide alloy blank is fired by many producers and used, because pressurized sintering furnace is when working, internal pressure is very large, temperature is very high, and after often completing a sintering cemented carbide, stove needs cooling.Existing carbide alloy pressurized sintering furnace is only provided with a dewaxing mouthful, and like this, on the one hand, the carbon potential of single dewaxing mouth is denseer; On the other hand, once there is this single dewaxing mouthful obstruction, must close immediately this sintering furnace and keep in repair.
In sum, how to make the sintering furnace dewaxing mouthful uniform problem of carbon potential, become those skilled in the art's problem demanding prompt solution.
Utility model content
The technical problems to be solved in the utility model is for a kind of carbide alloy pressurized sintering furnace is provided, and this carbide alloy pressurized sintering furnace arranges two dewaxings mouthful on body of heater, and the carbon potential while making the dewaxing of this sintering furnace is more even.
For solving the problems of the technologies described above, the utility model provides a kind of carbide alloy pressurized sintering furnace, comprise: body of heater and fire door, described fire door is arranged on the two ends of described body of heater, in the bottom of described body of heater, be provided with symmetrically two dewaxings mouthful, two described dewaxings mouthful connect described body of heater and space outerpace; Distance between two described dewaxings mouthful and separately adjacent described fire door is 1/5～1/3 of described body of heater length.
The beneficial effects of the utility model are:
By the bottom at body of heater, be provided with symmetrically two dewaxings mouthful, on the one hand, make in dewaxing process carbon potential more even; On the other hand, two dewaxings mouthful can be used alternatingly, just in case just occurring in dewaxing process that dewaxing mouth stops up, also do not need to close immediately stove.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, other accompanying drawing can also be provided according to the accompanying drawing providing.
Fig. 1 is the structural representation of carbide alloy pressurized sintering furnace in the utility model embodiment.
The specific embodiment
Core of the present utility model is for a kind of carbide alloy pressurized sintering furnace is provided, and this carbide alloy pressurized sintering furnace arranges two dewaxings mouthful on body of heater, and the carbon potential while making the dewaxing of this sintering furnace is more even.
In order to make those skilled in the art understand better the technical solution of the utility model, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The present embodiment provides a kind of carbide alloy pressurized sintering furnace, please refer to Fig. 1, this carbide alloy pressurized sintering furnace comprises: body of heater 1 and fire door 2, fire door 2 is arranged on the two ends of body of heater 1, in the bottom of body of heater 1, be provided with symmetrically two dewaxings mouthful 11, two dewaxing mouthful 11 perforation body of heater 1 and space outerpaces; Distance between two dewaxings mouthfuls 11 and separately adjacent fire door 2 is 1/5～1/3 of body of heater 1 length.Preferably, two dewaxings mouthfuls 11 and separately the distance between adjacent fire door 2 be 1/4 of body of heater 1 length.
Above a kind of carbide alloy pressurized sintering furnace provided by the utility model is described in detail.Applied specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment is just for helping to understand method of the present utility model and core concept thereof.Should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
Claims (1)
1. a carbide alloy pressurized sintering furnace, comprising: body of heater (1) and fire door (2), and described fire door (2) is arranged on the two ends of described body of heater (1), it is characterized in that,
In the bottom of described body of heater (1), be provided with symmetrically two dewaxings mouthful (11), two described dewaxings mouthful (11) connect described body of heater (1) and space outerpace;
