Embodiment Construction
[0019] First of all, the original design intention of the present invention is explained. Electroslag furnace is an indispensable production equipment in special steel mills. At present, coaxial electroslag furnaces at home and abroad have no protective cover device, and some equipment have protective cover device. Most of the protective cover devices are two-door or four-door protective cover devices, and the overall airtight effect is not so good, so that the quality of the smelted steel ingots is not good, and the yield rate is also greatly reduced. In addition, during the smelting process, many The enterprise reduces the oxygen content in the smelting space by increasing the gas supply of argon gas. This method increases the production cost and also increases the safety risk. Therefore, the present invention designs a new airtight protective cover device for the electroslag furnace.
[0020] The present invention is specifically described below in conjunction with accompany...
