复合预还原球团矿的试验研究［印度］Ｔ．Ｓｈａｒｍａ１前言预还原球团矿是电炉中代替废钢的良好原料。尽管应用预还原球团矿具有一系列优点，但由于其热耗大和耐风雨侵蚀能力差，它们还没有广泛应用于炼钢。复合预还原球团矿的开发克服了这些问题，只通过焙烧一步就生产... Experimental study of composite prereduction pellets [India] T. Sharma1 Foreword Pre-reduced pellets are a good source of scrap in electric furnaces. Although the application of prereduction pellets has a number of advantages, it has not been widely used in steelmaking due to its high heat loss and weather-resistance. The development of composite pre-reduced pellets overcomes these problems by producing only one step of roasting ...
