Abstract
At present, the silicon carbide ceramic reaction sintering process is widely used in high-temperature sintering furnaces, the bottom of which is made and the conditions of use vary with the use of alkaline refractory materials. It includes furnace body, furnace cover, holding tank, hot pressing device, heat generator and power supply, vacuum system, water cooling system and temperature measurement system. The following with zhongyi high temperature sintering furnace manufacturers say at this stage of the two basic cooling methods.
1, can be cooled directly with water.
Installed in the conductive electrode drilled tube, between the conductive electrode and copper busbar water, so that it is cooled. This direct cooling method is simple, trouble-free, and the cooling effect is very good. The disadvantage is that the cooling water splash, easy to cause the furnace body seepage. Moreover, this method also requires the installation of a water drain sink, which is easy to be clogged, and if it is not handled well, the water in the sink can easily seep into the furnace chamber, and the sprayed water can easily seep into the furnace chamber, which shortens the service life of the furnace, and it is also easy to oxidise. In addition, it is easy to freeze near the sink in northern winter, which is not easy to handle.
2. Internal cooling:
Conductive electrode after drilling, can be directly plugged with wire, and then connect two long and short water pipe, so that the water can flow directly into the electrode's round hole. High-temperature sintering furnace fixed side walls are generally made of refractory bricks, every certain distance should be left a discharge holes to ensure that the smoke in the core of the furnace in the process of power supply can be discharged smoothly. With refractory bricks as side walls, good thermal insulation, long life, but high cost.
3. Gas-fan cooling, the former procedure with the gas cooling. The difference is that when the inert gas is passed into the high-temperature sintering furnace vacuum pressure reaches 300 torr, vacuum sealing fan motor rotation; stirring airflow, accelerating the cycle to improve the cooling rate of less than 30rc 3 when the vacuum chamber pressure reaches 650 torr, the check valve automatically closes to stop the ventilation, cooling to below 65P until.
