Furthermore, the water-cooling support is formed by welding three seamless steel pipes side by side, each steel pipe is bent at an angle of 120 degrees at the center, and straight pipe parts of the steel pipes are combined together.
Furthermore, the water-cooling support is composed of a stainless steel seamless steel pipe.
Further, the inner ring water-cooling pipe, the outer ring water-cooling pipe and the water through pipe are all made of stainless steel seamless steel pipes.
Furthermore, the water-through furnace cover of the high-temperature resistant submerged arc furnace can be used for production of various submerged arc furnaces.
Furthermore, the high-temperature-resistant submerged arc furnace water-through furnace cover is characterized in that the refractory material building blocks are formed by building refractory bricks and refractory slurry and are built between the two water-cooling blocks.
To sum up, the utility model discloses a following beneficial effect:
1. the utility model relates to a hot stove in ore deposit of high temperature resistance leads to water bell changes circular stainless steel pipeline into through square pipeline before, and then reduces the mobile state in the pipeline when circulating water gets into the pipeline, thereby reduces the phenomenon that the pipeline was corroded to the sticker that produces under the high temperature.
2. The utility model relates to a hot stove in ore deposit of high temperature resistance leads to water bell, through the hot stove in ore deposit that forms with the concatenation of stainless steel pipeline leads to water bell water cooling system of high temperature resistance, has reduced the welding seam of the pipeline that forms by the corrosion resistant plate welding before, great reduction because the welding seam breaks the phenomenon that stops stove and influence production that appears after leaking.
