冶金部鞍山焦化耐火材料设计院与江都冶金机械厂合作,在消化吸收日本80年代末期6m焦炉先进经验的基础上,创新设计并研制成功一种更为先进而又适合国情的焦炉设备——JN43—90型焦炉炉门、炉框、保护板。目前该产品已在首钢集团公司北京焦化厂正式投入运行。该产品是封闭焦炉炭化室、保护炉体的专用设备。它采用了6m焦炉弹簧门栓的新型结构,使门栓作固定式水平运动,刀边受力更加均匀;另外在炉框上增加了两个支承轮,使炉门在其支承上作滚动运动,避免了
Metallurgical Department Anshan Coking Refractory Design Institute and Jiangdu Metallurgical Machinery Factory, Japan, Japan in the digestion and absorption of 6m coke oven advanced experience based on the innovative design and development of a more successful and more suitable for the national conditions of coke oven equipment - -JN43-90 coke oven door, furnace frame, protection board. At present, the product has been formally put into operation at Shougang Group Beijing Coking Plant. The product is closed coke oven carbonization room, protect the furnace of special equipment. It uses a new structure of 6m coke oven spring bolt, so that the bolt for the fixed horizontal movement, the blade edge force more uniform; addition in the furnace frame added two support wheels, so that the door on its support for rolling Exercise, avoided
