FURNACE MATERIAL AND MANUFACTURING METHOD OF FURNACE MATERIAL

摘要

PURPOSE: A furnace refractory material with the excellent in lithium reactivity, and a producing method thereof are provided to prevent the generation of a bonding layer of glass materials for effectively controlling the damage on the furnace refractory material. CONSTITUTION: A furnace refractory material contains 95~99.9mass% of mixture including MgO and Al2O3. The specific gravity of the furnace refractory material is 1~2.5. the producing method of the furnace refractory material comprises a step of mixing all materials including a pore forming agent, and a step of plasticizing the mixture at 1,400~1,700deg C. The furnace refractory material uses periclase or spinel with the average particle diameter of 0.8~2mm as an aggregate material.
