[0002] Fused magnesia is a general term for the products of magnesia raw materials such as magnesia that have been sintered after high-temperature treatment. The magnesia made from natural magnesia as raw material by a single calcination or two-step calcination process using high-temperature equipment such as vertical kilns and rotary kilns is called sintered magnesia; the magnesia made from magnesia ore and other raw materials that has been smelted in an electric arc furnace to a molten state and then cooled is called fused magnesia.

[0003] When the electric fused magnesia furnace is in use, a furnace cover is required. However, the furnace cover does not have wear resistance and heat insulation when in use, which leads to damage to the furnace cover and inability to use normally after long-term use. In addition, the poor heat insulation effect causes the electric fused magnesia furnace to have poor performance. Utility Model Content

[0013] 1. The utility model cooperates with the first wear-resistant layer, the base layer and the second wear-resistant layer to play a wear-resistant role for the furnace cover body when it is in use, thereby avoiding the poor wear-resistant effect of the furnace cover body, which leads to damage to the furnace cover body and the inability to use the furnace cover normally.
