APPARATUS FOR COOLING SHAFTS OF METALLURGICAL FURNACES

摘要

FIELD: metallurgy, namely apparatuses for cooling shafts of metallurgical furnaces. ^ SUBSTANCE: cooling apparatus includes plate having protrusions on its working surface and cooling system. Distance from working surface plate till nearest surface of duct of cooling system consists of 0.07 - 0.60 of plate thickness. Total surface area of bases of all protrusions consists of no more than 0.95 of surface area of working surface with protrusions. Lateral walls of protrusions are inclined by angle 10 - 170° relative to working surface of plate. ^ EFFECT: improved exploitation stability of plate type cooling apparatus. ^ 6 cl, 2 dwg, 1 ex
