我市三三二钢铁厂及干霸子焦化厂利用砚石台肥煤(V~r29.81％,Y45.5毫米)及南桐焦煤(V~r19.16％,Y16.5毫米)分别配入30～70％松藻煤矿无烟煤(V~r9.72％,Y0毫米),在土法炼焦炉中进行试验。试验结果表明:砚石台肥煤配入50％无烟煤时,配煤V~r为19.77％,Y为22毫米,焦炭坠落强度(大于25毫米)占86％,可供中小型高炉使用。无烟煤再增加配比则末能全部融熔。把南桐焦煤配入20％无烟煤时,亦未全部融熔;如再增加无烟煤,则不能粘结。
Three hundred and thirty-two iron and steel plants and dry bully coking plant in the city use Yantai station fat coal (V ~ r29.81%, Y45.5 mm) and Nantong coking coal (V ~ r19.16%, Y16.5 mm) With 30 ~ 70% Songzao coal anthracite coal (V ~ r9.72%, Y0 mm), in the indigenous coke oven test. The test results show that when Yantaitai fat coal is mixed with 50% anthracite, the V r of blending coal is 19.77%, Y is 22mm, and the coke falling strength (more than 25mm) accounts for 86%, which can be used for small and medium-sized blast furnaces. Anthracite and then increase the proportion of all can be melted. Nantong coking coal with 20% anthracite, nor all of the melt; such as the increase of anthracite, you can not bond.
