原理用于冶炼生铁的高炉和重熔生铁、废钢的冲天炉结构极其相似。但由于其用途不同,所需的燃烧条件也不同。高炉用于铁矿石还原。它所用的焦碳应具有较高的反应能力,一般采用冶金焦。鼓风量应予严格控制,以限制燃烧释放的热量和火焰温度。冲天炉用于重熔废钢、旧铁及新生铁,并过热铁水。它所用的焦 Principle Used for smelting pig iron blast furnace and remelting pig iron, scrap steel cupola structure is very similar. However, due to their different uses, the required combustion conditions are also different. Blast furnace for iron ore reduction. It uses coke should have a higher response capacity, the general use of metallurgical coke. The blast volume should be tightly controlled to limit the amount of heat and flame released by the combustion. Cupola used to re-melt scrap, old iron and new-born iron, and overheated hot metal. It used the coke
