[0002] In the metallurgical industry, water-cooled furnace covers are commonly used equipment, mainly used to protect the furnace body and control the temperature inside the furnace. Traditional water-cooled furnace covers cool the furnace covers through a cooling water circulation system, thereby protecting the furnace covers from erosion by high-temperature slag. However, during long-term use of existing water-cooled furnace covers, due to the chemical substances contained in the cooling water and the thermal stress of metal materials in high-temperature environments, metal parts are prone to corrosion and aging, which in turn leads to cooling water leakage.

[0003] At present, the water-cooled furnace cover in the prior art usually includes a furnace cover body, a metal hose, an inlet and return water distributor and other components. The cooling water circulates through the metal hose to achieve the cooling effect of the furnace cover. However, at the connection parts of the metal hose, especially the connection parts with the inlet and return water distributor, flange and other components, cracks or welding point failures caused by metal corrosion and thermal stress often lead to cooling water leakage. This not only affects the cooling effect of the furnace cover, but also may cause serious damage to the furnace cover, increase repair costs, and even affect production safety. Utility Model Content

[0007] Furthermore, the furnace door is connected to the furnace door frame through a hinge for opening and closing the furnace door.

[0008] Furthermore, the flange is connected to the furnace body by bolts to fix the furnace cover body.
