本溪钢铁公司5号高炉(2000m~3)从第二代开始,由于使用的国产大炭块质量较差,加上大炭块自身固有的缺陷,投产后侵蚀严重,炉缸冷却壁水温差超标,不能适应高炉强化冶炼的需要,被迫靠钒钛矿护炉和降低冶炼强度维持生产,每隔三年左右即大修一次,为扭转被动局面,决定在第四代大修设计中将炉缸与炉底交接处3.2m高靠近冷却壁的环砌炭砖,选用美国联合炭化有限公司生
Benxi Iron and Steel Company No. 5 blast furnace (2000m ~ 3) from the second generation, due to the poor quality of the large domestic carbon block, coupled with the inherent shortcomings of large carbon block, serious erosion after commissioning, hearth cooling wall water temperature exceeds the standard , Can not meet the needs of the blast furnace to strengthen smelting, was forced to rely on vanadium-titanium ore furnace and reduce the intensity of smelting to maintain production, every three years or overhaul, in order to reverse the passive situation, decided to design the fourth generation of overhaul will hearth and Bottom of the junction 3.2m high near the cooling wall of the brick wall, the United States selected carbonization Co., Ltd.
