Casting forming method of cooling wall of kiln furnace body of metallurgical furnace

The invention relates to a casting forming method of a cooling wall of a kiln furnace body of a metallurgical furnace. The casting forming process of the invention comprises the steps of fixing metal pipes in the center of sand molds and casting metal liquid into the sand molds for forming. The invention is characterized in that when the metal liquid is cast into the sand molds, high-temperature water vapor is introduced in the metal pipes. When the casting forming method of the cooling wall of the kiln furnace body of the metallurgical furnace of the invention is adopted, cooling water passages of the cooling wall can not deform and can not be burnt through in the casting process, in addition, higher casting temperature can be adopted, good fusion effect of the metal pipes and the casting metal liquid is ensured, and the invention is favorable for the gas exhaust of molding cavities and the metal liquid to form compact castings. Through the detection, the fusion rate reaches more than 95 percent, and the gas
