Production process and wear prevention of alumina ceramic parts
Production process and wear prevention of alumina ceramic parts
alumina ceramic parts are used in many industrial production occasions, which fully shows that ceramic parts have many superior properties compared to other materials, and they will become popular in the industry. At present, alumina ceramics can be mainly used for protection tubes and insulating tubes of temperature measuring instruments, thermocouple thermometers; at the same time, it can also be used in furnace tubes of industrial resistance furnaces, experimental electric furnaces, and heat treatment furnaces.
In addition, the steel chemical analysis carbon tube and sulfur tube, as well as other high temperature, acid and alkali corrosion resistant insulation instrument components, all use ceramic ceramic parts as the basic parts. It seems that alumina ceramics use its strong mechanical strength, thermal shock resistance; good thermal conductivity, insulation; and higher softening temperature and other advantages, which have come in handy in many industries and are of great significance.
The production process of alumina ceramic parts is generally divided into three main steps. In order to ensure its quality, every link must be done well. The first is the preparation of ceramic powder as a raw material. If you are manufacturing general-purpose ceramic parts, there are ready-made spray-dried granulating powders on the market; if you need to control the material formula yourself, you need to buy a ball mill, a ball, and a spray dryer.
After having the raw materials, you can start pressing. For sheet products smaller than 2 mm, you can consider using the method of gelation; and for ceramics larger than 2 mm, you can consider using the method of pressing. It is followed by sintering and processing. If the alumina ceramics are sintered in large quantities, they can be continuously produced in a tunnel kiln; and the processing is mainly determined according to the complexity of the product. Some ceramics do not need to be processed, and the mold can be directly sold.
Alumina ceramic parts are a very versatile product, but in actual use, alumina ceramic parts will inevitably be worn. There are many factors that cause structural parts to wear. These aspects can be used to effectively prevent alumina Wear of ceramic structural parts.
First of all, we should try our best to avoid collision with objects during operation to reduce damage. Alumina ceramic parts will experience a certain degree of wear after being used for a long time, but this is a normal phenomenon and only needs to be replaced after excessive wear.
