1. the thickness of furnace wall can be reduced by half according to the traditional refractory materials, and the weight of furnace wall can be reduced by one fifth and one tenth.

2. because the fiber has small heat storage, it can greatly improve the heating rate and cooling rate of the furnace.

3. convenient construction, time-saving and labor-saving

4. prefabricated parts and integrated blocks can be used to assemble the furnace

5. shorten construction period

6. resistant to rapid cooling and heating

7. the fiber has low thermal conductivity, good thermal insulation performance, less heat absorption, and saves raw materials

8. suitable for computer process control with strong applicability
