Process technology of graphite block

1. High temperature resistance: Graphite block is one of the most high temperature resistant materials known at present. Its melting point is 3850℃±50℃, and its boiling point reaches 4250℃. It has the least loss of graphite at 10S under 7000℃ ultra-high temperature arc. Graphite loses 0.8% by weight. It can be seen that the high temperature resistance of graphite is very outstanding.

2. Special thermal shock resistance: Graphite has good thermal shock resistance, that is, when the temperature changes suddenly, the coefficient of thermal expansion is small, so it has good thermal stability, and it will not crack when the temperature changes rapidly. .

3. Thermal conductivity and electrical conductivity: Graphite has good thermal and electrical conductivity. Compared with ordinary materials, its thermal conductivity is quite high. It is 4 times higher than stainless steel and 2 times higher than carbon steel. The general non-metal is 100 times higher.

4. Lubricity: The lubricating performance of graphite is similar to that of molybdenum disulfide, and the friction coefficient is less than 0.1. Its lubricating performance varies with the size of the scales. The larger the scale, the smaller the friction coefficient and the better the lubricity.

5. Chemical stability: Graphite has good chemical stability at room temperature, and is resistant to acids, alkalis, and organic solvents.
