Description
Technical field
The present invention relates to industrial furnace technical field, more particularly to a kind of vacuum degreasing fritting furnace.
Background technology
Sintered products are generally all located in hopper and formed by what sintering furnace was fired, and hopper (also referred to as Muffle) is by graphite system
Into being very important device in vacuum degreasing sintering furnace.Why product (processed material) is wrapped using hopper, one
It is that its conduction of heat is very good, heat leakage very little, can equably ensures that each local temperature in hopper is consistent, when adds
Hot body heating, temperature is by the way that on conduct radiation to hopper, the temperature of hopper raises, and in hopper temperature conduction to ceramic wafer, then leads to
Cross ceramic wafer to be transmitted on product, the temperature of conduction is highly uniform, makes the temperature of the product in whole hopper ensure certain
In temperature range, the product size of such degreasing and sintering out is easier to control in the margin of tolerance.Second, it have it is certain
Sealing, hopper by furnace atmosphere be divided into hopper and hopper outside two kinds of atmosphere, can guarantee that gas flow, prevent binding agent steam
Run about and pollute heat-insulated material (after the pollution of heat-insulated material, vacuum in stove it is difficult to ensure that, product appearance will be impacted), hopper
One end of degreasing pipe in hopper with connecting, and the other end connects with pipeline vacuum pump, and after vacuum pump operation is evacuated, gas is filled with stove
It is interior, the air-flow to centre by both sides will be formed in hopper, makes hopper is inside and outside to produce pressure differential, and hopper external pressure is more than material
Pressure in case, it is ensured that air-flow will not go to outside hopper the heat-insulated material that depollutes.
The process of traditional vacuum degreasing sintering furnace is：After the built-in product of producing at full capacity of stove, first to being vacuumized in stove (because stove
Interior graphite piece can aoxidize at high temperature, so to be reheated under vacuo under protective atmosphere), make to reach certain negative pressure in stove,
Evacuation process terminates, and degreasing process starts.Then start to warm up, protective gas is vacuumized and be filled with heating, at 200 DEG C
Left and right, the binding agent in product can slowly gasify, pass through degreasing pipe with the gas of current-carrying, enter pipeline and catch in fat device,
Current-carrying gas constantly takes away binding agent steam, waits to be warming up to 600 DEG C or so, after held for some time, and degreasing process terminates, and enters
Sintering process.Heated up when vacuumizing, remaining binder steam in stove is extracted, kept furnace atmosphere clean, wait to be warming up to 850
DEG C or so (now binding agent has substantially all been removed and drained only), start to be filled with the gas of certain flow, make hopper
It is inside and outside to ensure certain pressure difference, continue to be warming up to product sintering temperature, typically at 1300 DEG C or so, held for some time, sinter
Technique terminates, into cooling technique.Cooling starts to naturally cool to 900 DEG C or so from 1300 DEG C, and then blower fan starts, on hopper
Lid is opened, hopper internal and external pressure balance, gas circulating flow, and through subcooler, temperature declines gas, then before being delivered to by impeller
Door, flows through hopper, then flow to cooler, and so constantly circulation carries out heat exchange, to accelerate to cool down, until in-furnace temperature reaches
Room temperature, blower fan stop, and cooling technique terminates, and material box cover is closed, and product can just come out of the stove.
The hopper of traditional vacuum degreasing sintering furnace is integrally fixed in stove, referred to as fixed hopper, during charging, is leaned on
The flitch for filling product is inserted in hopper manually, then closes fire door, the process operations such as degreasing, sintering, cooling is carried out, treats technique knot
Shu Shi, fire door is opened, then artificially the flitch for filling product is taken out manually, remove product.But when cooling down, cooling rate is very
Slowly.It can be seen that the production efficiency of traditional vacuum degreasing sintering furnace is relatively low.
