我厂22米~3高炉生产磷肥,以往是使用焦炭作为燃料,为了改变与钢铁争焦的局面,寻求新的燃料路线,生产更多的磷肥,支援农业,我们利用现有设备,以上海煤炭供应公司龙华煤场生产的“冷压焦结煤球”(以下简称球焦)代替焦炭生产磷肥。从78年5月开始至6月底止进行了35天的生产试验,取得了较好的效果。100％球焦代替焦炭生产磷肥,其平均日产量为:136吨,平均标准焦比363公斤/吨肥(最低标准焦比266公斤/吨肥),磷的转化率98.48％,成本每吨肥可下降6元左右。基本上对球焦在生产中
In order to change the focus of the situation with iron and steel, seek new fuel routes, produce more phosphate fertilizer and support agriculture, we use existing equipment and use the coal from Shanghai Coal Supply company Longhua coal production “cold pressure coke briquettes” (hereinafter referred to as the ball coke) instead of coke to produce phosphate fertilizer. From May 1978 to the end of June only 35 days of production test, and achieved good results. The average daily coke production was 136 tonnes with an average daily coke yield of 363 kg / t (minimum standard coke ratio of 266 kg / t), phosphorus conversion rate of 98.48% and cost per tonne of fertilizer Can be reduced about 6 yuan. Basically focus on the ball in the production
