摘要
兰炭又称半焦炭,以高挥发分的弱粘结或不粘结性煤为原料,经中、低温干馏炭化制备,是一种廉价碳素原料.在焦炭价格上涨的情况下,建议本来就利薄的电石生产厂掺用兰炭.经在23 MW开放电石炉上试用,掺30%～40%的兰炭,各项操作指标达到最佳.
As new economical carbonic material,semi-coke is produced by carbonization from highly-volatiled and non-binding coal under middle or low temperature. In order to improve product quality and decrease cost,carbide producers are suggested to blend 30%~40% semi-coke in opened carbide furnance with 23 000 KVA.
