Cooling board for the metallurgical furnace

FIELD: metallurgy industry; production of the cooling devices of the metallurgical furnaces. SUBSTANCE: the invention is pertaining to the field of metallurgy, in particular, to the cooling devices of the metallurgical furnaces. The cooling board consists of copper or of the low copper alloy for the metallurgical furnaces supplied with the exterior facing made out of the steel sheet predominantly with two channels passing inside the cooling board and used for the cooling liquid. The fitting pipes used for the cooling liquid are brought outside through the facing from the steel sheet. On the cooling board fastening tubes are installed. The cooling board is fixed in the direction to the internal cavity of the furnace. The fastening tubes from an outer side of the facing made out of the steel sheet are supplied with the bracketry. The fastening tubes and the bracketry are manufactured mainly out of the steel.

Thermal protection of shaft furnace walls in smelting - using metal plates attached to cooled tubes

Metal plates having a height to width ratio of 2 to 3:1, which are used for thermal protection of the shells of shaft furnaces for smelting, are made up of individual bars, of which the width exceeds the height. The surfaces of the bars facing the furnace shell are provided with recesses into which U-shaped coolant-conveying tubes are fitted. A thermally conductive material is placed in the recesses to improve heat transfer from the plates to the coolant flowing inside the tubes. Elements are located between the recesses for attaching the bars to the tubes. Further elements are welded to the tubes so that they can be secured to the furnace shell. Differential thermal expansion in the vertical direction can be taken up without developing the material stresses which occur in one-piece plates. The life of the plates is increased and the time between repairs is extended. The probability of dangerous situations arising is reduced.
