  • Manufacturing method of magnesium-aluminium spinel brick and magnesium-aluminium spinel brick manufactured by the method
    Patent number: 11299433
    Abstract: A manufacturing method of a low heat-conducting magnesium-aluminium spinel brick includes: (1) evenly mixing sintered magnesia, fused magnesia, magnesium-aluminium spinel and corundum to prepare flame retardant coating raw material mixed powder, adding naphthalene binder to the flame retardant coating raw material mixed powder to prepare the flame retardant coating raw materials after evenly mixing; (2) evenly mixing forsterite, fayalite and magnesia, adding the naphthalene binder to the mixed powder, moulding, drying, and then burning to obtain aggregate composite hortonolite raw materials; adding the naphthalene binder to the aggregate composite hortonolite having granularity ?5 mm to prepare the thermal insulating layer raw materials after evenly mixing; (3) spacing and loading the flame retardant coating raw materials and the thermal insulating layer raw materials in a mold, pressing into green bricks, keeping the green bricks at a temperature of 110° C.
