Machining technology for metal ceramic flange

Abstract

The invention relates to a machining technology for a metal ceramic flange. The machining technology is characterized by comprising the steps that firstly, powdery raw materials are added into a container according to the weight ratio and are evenly stirred, and then a proper amount of water is added for even stirring; secondly, the surface of the inner wall of a die is coated with a layer of release agent, the die is filled with the raw materials, and the raw materials in the die are pressed through a pressing plate; thirdly, the die is heated to evaporate water in the flange, and then the flange in the die is pressed after evaporation; fourthly, die releasing is conducted on the formed flange, and then some burrs are cut; fifthly, the flange obtained after die releasing is put into a combustion furnace to be heated for 15 min to 25 min at the temperature ranging from 600 DEG C to 800 DEG C, and then sintering is conducted for 10 min to 20 min at the temperature ranging from 1200 DEG C to 1300 DEG C; sixthly, after sintering forming is conducted, the temperature is gradually reduced to 200 DEG C, and the flange is taken out and cooled to the room temperature; and seventhly, the cooled flange is checked, and some burrs are ground. According to the machining technology, the steps are simple, operation is easy, the produced flange is high in hardness and small in weight, and the production cost is saved.

Description

technical field [0001] The invention relates to a processing technology of a flange, in particular to a processing technology of a flange made of cermet material. Background technique [0002] Existing flanges are generally made of stainless steel or carbon steel. These flanges generally have high hardness and are not easy to rust, but their high density will greatly increase the overall weight, which will cause a burden both in transportation and in subsequent use. , and the cost is high, the processing and production time is long, and the flange needs to be polished during production. The dust after grinding will explode in case of fire, which is very unsafe. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the invention provides a processing technology for a cermet flange. [0004] In order to achieve the above object, the present invention is achieved through the following technical solutions: [0005] A processing technique for a cerme...
