Description

Technical Field

[0001] The utility model relates to the field of heating furnaces, in particular to a heating furnace cover. Background Art

[0002] A heating furnace refers to a device in the metallurgical industry that heats materials or workpieces to the rolling or forging temperature. Heating furnaces are used in many industries such as petroleum, chemical industry, metallurgy, machinery, heat treatment, surface treatment, building materials, electronics, materials, light industry, daily chemicals and pharmaceuticals.

[0003] The heating furnace includes a furnace body and a furnace cover arranged on the furnace body. The furnace in the furnace body burns the fuel, and the furnace cover seals the furnace mouth of the furnace body. However, when the furnace cover is currently installed above the furnace body, it is usually installed with hinges and then opened and closed manually. It does not have a structure for automatic opening and closing. Manual opening and closing of the furnace cover is prone to burns caused by the high-temperature gas inside the furnace body, which then poses a safety hazard. To this end, we propose a heating furnace cover to solve the above problem. Utility Model Content
