    A cooling element for use in metallurgical furnaces, such as blast furnaces, and a method of making the same. The cooling element is composed of a cast-steel body having a surface which in use faces the interior of the respective furnace and which is provided with elements of refractory material. Embedded in the cast-steel body are steel tubes through which cooling medium is to be circulated when the element is in use. Embedded between the respective tubes are heat-absorbing members which are preferably of the same or an analogous material as the cast-steel body itself and which have the purpose of absorbing the temperature differential between the liquidous point of the steel melt and the superheated temperature at which the melt is cast.

    The invention relates to metallurgy, and in particular to methods for manufacturing the cooling elements of metallurgical furnaces.
    The closest to the proposed technical essence is the method of fabrication and cooling of one of the elements of a metallurgical furnace, the installation of cooling pipes in forms, coating of pipes with carbon coating, installation of internal reinforcing inserts, filling of internal cavities of cooling pipes with granular material, pouring metal; as well as a device for manufacturing a cooling element of a metallurgical furnace comprising a housing, cooling pipes with a protective coating, internal reinforcing inserts C13.
    The lack of a known method and device is that the durability of the cooling element is lowered due to the melting of the cooling tubes, the destruction of the cooling of even the element facing the interior of the metallurgical furnace.
    The purpose of the invention: - increase the durability of the cooling element with thermal effects.
    The goal is achieved in that according to the method of manufacturing a cooling element of a metallurgical furnace, including installation of cooling tubes in the molds, coating the pipes with an installation of internal reinforcing inserts, filling the internal cavities of the cooling tubes with granular material, pouring formulas with metal, before pouring the cooling tubes are filled with dioxide zirconium, chromium dioxide or a mixture containing at least 20% of these materials, and the form is poured with liquid steel. with a temperature of 30-90 ° higher than eratury liquidus for 3 min.
    A mold device for fabricating a cooling element of a metallurgical furnace, including a housing, cooling pipes with a protective coating, and internal reinforcing inserts, is characterized in that reinforcing inserts are placed parallel to the cooling tubes with a gap relative to them with respect to the volume of reinforcing inserts to the volume of the mold in within 1 / 10-1 / 20 ..
    If the volume is less than 1/20 of the casting mold, then when the steel is poured with liquid superheated melt, the coolant pipes will be attacked and partially destroyed. If the volume is greater than 1/10, then when the mold is cooled after pouring due to different temperature reduction of the foundry
     and nested or suspended reinforcing inserts, cracks from thermal stresses occur in the mold, which make it possible to use a fabricated cooling element.
    Pour steel melt of the following composition, wt.%: With 0.15-0.50; Sl 0.30-0.80-, MP 0.50-2.0; Mr max. 1,00; Ct-max 2.50 A1 max. 0.1, the rest is iron and inevitable impurities.
    For embedded elements rec-. it is recommended to use the same co. steel melt is a material in which carbon content is no more than 0.2, manganese is no more than 0.5, and silicon is no more than 0.50% of the composition of steel melt or steel melt. Preferably the content of C, Mn and Zi in the found elements is less than the content of C, Mn and Zi in the melt for casting.
    In addition, it is more efficient if 5 cooling tubes are filled with a refractory material with a high thermal conductivity of the front material before pouring around them; 0 CIR dioxide is used as the i oToporo. CONTENT I, chromium dioxide or a mixture containing more than 20% of these oxides. The solidification of the solid melt this granular material is removed from the steel tubes.
    The advantage of the proposed cooling is that it can be made in a simple way, without the need for large costs, f. In addition, the proposed cooling element has a longer service life than the known, decarburization of the surface, cracks and flashing, does not occur in it. five
