The physical and chemical properties of the circular tube.
1. Thermal shock resistance: able to resist rapid temperature change without being destroyed;
2. Thermal conductivity: under the condition of unit temperature gradient, the rate of heat flow through the material unit area is related to porosity;
3. Impact resistance: good impact resistance and long service life;
4. Slag resistance: ability to resist slag erosion at high temperature without damage.
