磐石镍矿冶炼厂采用精矿压团竖炉干燥、电炉熔炼、转炉吹炼流程。电炉的备料流程是结合磐石镍矿的具体建厂条件,经过试验后提出的。该流程利用磐石硫化铜镍精矿较粘、容易成团的特点,精矿在不加粘结剂的条件下,经过一次混碾后在对辊压团机上压团。所得湿团块质量较好,+20毫米块料占80%,抗压强度达20公斤/个,从一米高落到料堆上三次。 Rock nickel ore smelting furnace with fine crushed shaft furnace drying, electric furnace smelting, converter blowing process. EAF preparation process is a combination of rock nickel ores specific construction conditions, after the test made. The process utilizes the characteristics that the rock copper sulphide nickel concentrate is more viscous and easy to agglomerate. The concentrate is crouched on the roller pressing machine after being mixed and grinded without binder. The resulting wet mass is of good quality, with a mass of 20 mm of 80% and a compressive strength of 20 kg / mass, falling from one meter to three on the heap.
