The Spring Festival is the most solemn traditional festival of the Chinese nation, with a hundred festival years as the first and four seasons spring as the first. Influenced by Chinese culture, some countries and regions around the world also have customs to celebrate the New Year. According to incomplete statistics, nearly 20 countries and regions have designated the Chinese New Year as a legal holiday for the whole or some cities under their jurisdiction. The holiday period is 7 days.

As a widely used material in ceramics, alumina ceramics presents the following development trends along with the development of the entire industry: (1) The level of technical equipment will be rapidly improved: the development of computer technology and digital control technology has promoted the technological progress and rapid development of the ceramic material industry, such as automatic control of continuous sintering kilns, high-power and large-capacity grinding equipment, and high-performance powder manufacturing Complete sets of equipment such as granular equipment and other net pressure forming equipment have beneficially promoted the improvement of the overall level of the industry, and at the same time, the production efficiency and product quality have also been significantly improved;

Jinzhou Yunxing Industrial Ceramics Co., Ltd. National Day holiday time: October 1st to October 7th. We normally accept order consultation during the holidays and arrange production after the holiday.

Jinzhou Yunxing Industrial Ceramics Co., Ltd. Due to the increase in business volume and product categories, the company built a new factory. Now the appearance of the office building of the new factory has been completed.

The ceramic material developed earlier is alumina ceramics. This material is resistant to high temperature and corrosion. It is an excellent and commonly used material. The material can be used to replace metal substances and extend the service life of the equipment. Increase the use of power.

Alumina ceramic tube sintering is a key stage of ceramic preparation, and the sintering atmosphere has a great influence on the preparation of ceramic materials. Too high sintering temperature or too long holding time will promote crystal growth, so that the fine raw materials will develop into coarse grains at high temperature, and the amount of liquid phase will increase. This will not only decrease the strength, but also weaken the wear resistance. Of course, if the temperature is too low, the sintered body will not be dense, and the wear resistance of the product will not be good.

Production practice and a large number of studies show that: low porosity, high density alumina ceramics have excellent structural properties. High density means that the crystal grains in the ceramic body are tightly arranged, and it is not easy to form destructive breakthrough points when subjected to external loads or corrosive substances.

In order to obtain alumina ceramic materials with high wear resistance, not only should it be considered to have high density, flexural and compressive strength, but also to increase its hardness and fracture toughness, and these properties are in line with the obvious characteristics of alumina ceramics. The microstructure (closed porosity, grain size, distribution of glass phase, etc.) and its wear mechanism are closely related.

In order to prolong the service life of high purity alumina furnace tubes and reduce the losses caused by damages due to improper use, the following suggestions are hereby put forward for users' reference

Alumina ceramicsare divided into two types: high-purity and ordinary.
