Double-layer cooling pipe balanced forced cooling water cooling furnace mouth

Abstract

The invention relates to a double-layer cooling pipe balanced forced cooling water cooling furnace mouth. The double-layer cooling pipe balanced forced cooling water cooling furnace mouth comprises a furnace mouth body and cooling pipes, wherein the upper layer cooling pipe and the lower layer cooling pipe are arranged in the furnace mouth body in a staggered and crossed mode and are the first cooling pipe and the second cooling pipe correspondingly; the first cooling pipe is arranged in a snakelike bend shape, and in the bend arrangement of the pipe, the first cooling pipe forms an upper peak part and a lower peak part when the pipe is bent; the second cooling pipe is also arranged in a snakelike bend shape, and in the bend arrangement of the pipe, the second cooling pipe also forms an upper peak part and a lower peak part when the pipe is bent; and the outer edge part of the furnace mouth body is provided with a plurality of mounting holes at intervals, and the furnace mouth body is internally provided with a plurality of hoisting holes which are distributed in a dispersed mode. According to the double-layer cooling pipe balanced forced cooling water cooling furnace mouth, the double-layer cooling pipes are arranged in a staggered mode to manufacture the water cooling furnace mouth, so that the cooling balance of the water cooling furnace mouth is improved, the water passing amount of the water cooling furnace mouth is increased, the using effect of the water- cooling furnace mouth is effectively improved, and the service life of the water cooling furnace mouth is effectively prolonged.

Description

technical field [0001] The invention belongs to the metallurgical casting industry, in particular to a dual-layer cooling pipe balanced forced cooling water-cooled furnace mouth of a cast iron furnace. Background technique [0002] In order to increase the service life of the furnace mouth of the converter, the cast iron furnace mouth is generally cast with cooling pipes inside, and some strong cooling water-cooled furnace mouths also use double-layer cooling pipes, and water is passed through during use to reduce the body temperature of the furnace mouth, so as to obtain Better use effect and service life. [0003] Generally, the cooling tubes of the water-cooled furnace mouth with strong cooling double-layer cooling tubes are designed side by side, which can meet the working needs of the water-cooled furnace mouth under normal circumstances, but in some converters with poor working conditions or expanded converters, The distance between the molten steel and the water-cool...

AI Technical Summary

Problems solved by technology

[0005] The task of the present invention is to provide a double-layer cooling pipe balanced strong cooling water-cooled furnace mouth, using double-layer cooling pipes to make a water-cooled furnace mouth, which not only increases the water flow through the water-cooled furnace mouth, but also improves the cooling balance of the water-cooled furnace mouth It solves the problem in the above-mentioned prior art that the body of the furnace mouth cannot meet the cooling requirements due to the two cooling pipes being arranged side by side in the water-cooled furnace mouth but unevenly distributed.
