PANELED FURNACE ARCH WITH SPRINKLING COOLING Russian patent published in 2001 - IPC

FIELD: arch with sprinkling cooling, in particular, for metallurgical furnace with a sunk arc designed for reduction of metal-containing oxide ores. SUBSTANCE: the metallurgical furnace arch is made in the form of separate detachable hollow metal sections snugged against one another, forming an internal hole for passing the electrode. It is provided with a means for feeding of liquid refrigerant directly and independently to the hollow metal section and the manifold pipe from the source of liquid refrigerant located outside the closed space, supporting member for the detachable joint with the annular peripheral wall secured in the lower part of the hollow metal section, means for holding the metal section in vertical. The detachable hollow metal section has an internal base component converged upwards, and an external metal covering component located at a distance from and in parallel with the internal metal base component. EFFECT: simplified design of metallurgical furnace arch and reduced overall dimensions of it. 6 cl, 7 dwg
