Abstract
The utility model discloses a vacuum sintering furnace which can fast cool the furnace temperature. A furnace door (2) of the vacuum sintering furnace is provided with a blower fan (8), and the other furnace door (1) is provided with a cooling coil pipe (5).The proper inert gases such as argon gas or nitrogen gas in the furnace fast flow in cycle which are driven by the blower fan through a heating device, a cooling coil pipe gap and a gap between the heating device and the furnace body; the heat of the heating device is fast transmitted to the cooling coiled pipe and cooling water in a water jacket, thus fast reducing the furnace temperature, shortening the production cycle, enhancing the production efficiency and reducing the production cost.
Description
The utility model relates to a kind of sintering equipment, particularly relates to a kind of vacuum sintering furnace that can cool off fast.
The hard alloy vacuum sintering furnace of present similar graphite heater behind the intact stove carbide alloy of sintering, is taked to feed inert gas such as a large amount of argon gas or nitrogen and water jacket and is fed cooling water and reduce furnace temperature in stove.The vacuum sintering furnace poor radiation of this structure, the furnace temperature decrease speed is slow, and the production cycle is long, and production efficiency is low, and the time of sintering one stove needs 24 hours, and will consume inert gases such as a large amount of argon gas or nitrogen, production cost height.
The purpose of this utility model provides a kind of vacuum sintering furnace, and it can not only reduce furnace temperature fast, and can also reduce production costs.
The purpose of this utility model is achieved in that on a fire door of vacuum sintering furnace a typhoon machine is installed, and the motor of blower fan is installed in outside the fire door, and impeller is installed in the fire door, and the motor of blower fan is equipped with water jacket, and this water jacket links to each other with water jacket on the body of heater.On another fire door, cooling coil is installed, the external cooling water of cooling coil.The external cooling water of this cooling coil.After sintering circuit is finished, in stove, feed inert gases such as an amount of argon gas or nitrogen by the wireway on the body of heater, open throttle setting and air door, start blower fan, make inert gas gap between electro-heat equipment, cooling coil gap, electro-heat equipment and body of heater in burner hearth, circulate fast, with the quick cooling water of giving in cooling coil and the water jacket that conducts of the heat of electro-heat equipment, by cooling water heat is taken out of outside the body of heater, thereby reached the purpose of quick reduction furnace temperature.
Because vacuum sintering furnace has adopted such scheme, can fast furnace heat be taken out of outside the body of heater, furnace temperature is descended fast, and only need small amounts of inert gas, thereby shorten the production cycle, improved production efficiency, reduced production cost.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the longitudinal sectional view of vacuum sintering furnace.
Fig. 2 is the transverse sectional view of vacuum sintering furnace.
Fig. 3 is a spiral of Archimedes coil pipe schematic diagram.
Among Fig. 1, on a fire door 2 of vacuum sintering furnace, one typhoon machine 8 is installed, the motor of blower fan 8 is installed in outside the fire door 2, impeller is installed in the fire door 2, the motor of blower fan 8 is covered with water jacket 7, on another fire door 1, cooling coil 5. is installed according to technological requirement, toward water jacket 4,7, feed cooling water in the cooling coil 5, after sintering circuit is finished, simultaneously in burner hearth, feed inert gases such as an amount of argon gas or nitrogen by the wireway on the body of heater 3 11, open throttle setting 9 and air door 6, start blower fan 8, make inert gas in burner hearth, pass through electro-heat equipment 10, the gap of cooling coil 5, gap between electro-heat equipment 10 and the body of heater 3, circulate fast, the heat of electro-heat equipment 10 is conducted the cooling water of giving in cooling coil 5 and the water jacket 4 fast, by cooling water heat is taken out of outside the body of heater, thereby can be reduced furnace temperature fast.
In above-mentioned vacuum sintering furnace, cooling coil 5 is pressed spiral of Archimedes dish system, and cooling effect is best, can make the production cycle shorten to 4～5 hours.
This vacuum sintering furnace is mainly used in sintered hard alloy, also can be applicable to stainless steel, magnetic material sintering.
Cooling coil in the utility model can be structures such as circular, snakelike, Archimedian screw.
