为满足冶金企业用煤的需要,遵照中央关于大力发展煤炭洗选加工的指示,焦作矿务局自1980年11月开始生产新产品一无烟洗精煤.该产品灰分低硫分低、挥发分低、固定碳高,适用于冶金企业炼铁高炉喷吹和矿粉烧结,经南京梅山铁厂和上钢一厂试用,效果较好,颇受欢迎. 使用效果:经梅山铁厂高炉喷吹试验表明,无烟洗精煤与不洗末煤比较,具有下列特点: 1.由于洗精煤灰分低,置换比可提高到0.85～0.90%,节省了焦炭及石灰石,降低了冶炼成本,增加了生铁产量,提高了经济效益. 2.洗精煤硫分低,对减少硫负荷,提
In order to meet the needs of the metallurgical enterprises with coal, in accordance with the central government’s directive on vigorously developing coal washing and processing, the Jiaozuo Mining Bureau started to produce a new product, smokeless clean coal, starting in November 1980. The product has low sulfur content, low volatility Sub-low, fixed carbon high, suitable for metallurgical enterprises blast furnace blasting and slag sintering, the Nanjing Meishan Iron Works and a trial of the steel plant, the effect is good, popular. Effect: The Meishan Iron and Steel blast furnace spray Blowing tests show that, compared with the non-wash coal, the smokeless clean coal has the following characteristics: 1. Since the coal ash content of the washed coal is low, the replacement ratio can be increased to 0.85-0.90%, coke and limestone are saved, the smelting cost is reduced, Increase the production of pig iron, improve economic efficiency. 2. Low sulfur content of coal washing, to reduce the sulfur load, mention
