Abstract

Improvements in the manufacture of cooling members for cooling systems of metallurgical furnaces, intended to prevent the carbonization of the metal tubes during the manufacture of said members, characterized in that they comprise the steps of coating the outer surface of the tubes that are must be used for cooling with a thin layer of a refractory material, placing the coated tubes inside a mold, and casting iron foundry maintained at a temperature within the range of 1180 to 1250ºC inside the mold to form the cooling members, the tubes being carbon-free due to the low casting temperature and the protective refractory material, said refractory material being formed essentially by 72 weight percent quartz sand, 20 weight percent refractory clay, percent by weight of water glass and water in the amount needed to obtain a mixture whose density is within the range of 1.4 to 1.6 g/cm3.
