| description | The utility model improves a small furnace cover of an electric furnace. The characteristics of the small furnace cover are as follows: layers (upper and lower) of ring-shaped channels with differentradial size are reserved on the thickness face of the furnace cover and at the periphery of an electrode hole, and each ring-shaped channel is provided with an outer connecting pipe which is stretchedout of the furnace cover. When in use, cooling air continuously enters the channels, so as to not only reduce the temperature of the furnace cover, but also be beneficial for forming a continuous high-viscosity dregs-adhering protective layer on the working surface in the furnace cover; the temperature reduction lessens damage to the furnace cover due to hot and structural stripping caused by large temperature difference when the small furnace cover is moved out; compared with the channels without ventilating and cooling, the service life of the furnace cover made of the same materials at least can be prolonged more t |
