DEVICE FOR COOLING METALLURGICAL UNIT WALLS Russian patent published in 1998 - IPC

FIELD: device for protection of metallurgical unit jackets. SUBSTANCE: device includes metallurgical unit jacket on which refractory layer accommodating cooling clamps made of thick-walled pipes is installed. In this case, pipes are installed so that distance from furnace jacket to axis of clamp vertical section equals 2.5-4.0 its of its outer diameters and protection screen is additionally provided with compensation device made of multilayer plates and rigidly fastened to jacket to form sections with plate width equalling the thickness of refractory layer equalling 4-6.5 clamp outer diameters. Clamp horizontal section-vertical section ratio is 1/14-1/10. Upper curved section of clamp along upper generating line has rid. EFFECT: higher operating reliability of metallurgical unit.
