我厂自3月底起推广了鞍钢先进的出铁大沟配料比,经过试用效果很大。其优点是:1.换一次能用5—6天;2.不挂铁水;3.节省材料;4.减轻工人的高温操作,铺好就能使用。现将配料比及使用方法介绍如下:(1)配料比:细焦末80%,沥青粉10%,以上两种粒度是:1/(16)″耐火土10%,每100公斤另加水分9—10公斤。(2)混合方法:把以上三种料准确过磅混匀,过1/4″筛子一次后,再把水均匀喷入用碾子轧一遍 Since the end of March I plant since the promotion of Anshan Iron and Steel advanced ditch ingredients ratio, after a great trial. Its advantages are: 1. For a 5-6 days; 2. Do not hang hot metal; 3. Save material; 4. To reduce the high-temperature operation of workers, paved can be used. Now the ingredients ratio and the use of methods are described below: (1) ingredients ratio: fine coke at the end of 80%, 10% asphalt, the above two kinds of particle size is: 1 / (16) “refractory soil 10% 9-10 kg. (2) Mixing method: The above three kinds of materials accurately weighed mix, after 1/4 ”sieve once, then the water evenly sprayed with a roller rolling again
