A few days ago, an invention patent of the company was authorized by the State Intellectual Property Office. The patent name is "a silicon nitride composite ceramic sintering furnace", and the patent number is cn210892651u.
The invention discloses a silicon nitride composite ceramic sintering furnace, which comprises a kiln car, a furnace body is movably installed on the kiln car, the furnace body and the kiln car form a relatively sealed hexahedral space, a furnace door is hinged on the furnace body, a combustion nozzle is installed on the inner wall of the furnace body, the kiln car also comprises a nitriding box, the nitriding box is arranged inside the furnace body, and a combustion nozzle is arranged at the bottom of the nitriding box The nitriding box is also provided with a plurality of support columns, and a sagger is arranged above the support columns. The utility model can avoid the influence of other harmful gases on the sintering quality, monitor the temperature and nitrogen pressure in the nitriding box through the monitoring hole, and control the temperature and speed of the reaction, which can effectively avoid the silicon flowing phenomenon of the products caused by too fast temperature rise, judge the nitriding degree through the pressure in the nitriding box, adjust the air intake, and keep the pressure in the nitriding box at a stable level all the time The temperature is controlled according to the change of pressure, so that the nitriding reaction can be fully carried out.
