红土镍矿冶炼镍硬铸铁试验

LATERITE NICKEL ORE SMELTING HARD CAST IRON TEST

为实现最终产品工艺的节能减排,在150 kW单相矿热炉中进行红土镍矿和铬矿直接生产镍硬Ⅳ型铸铁,产品含Ni 5.89%和Cr 8.96%,符合镍硬Ⅳ型铸铁的成分要求,可达到试验预期效果。因此,利用红土镍矿、铬矿通过矿热炉冶炼一步法生产镍硬Ⅳ型铸铁在技术上是可行的。

In order to achieve the energy saving and emission reduction of the final product process, Ⅳ Ni-hard cast iron is produced with lateritic nickel ore and chrome ore in 150 kW single phase submerged arc furnace and gets a Ni 5.89%and Cr 8.96% product, which fulfills the request of composition and can achieve the desired effect. It is feasible in technic of producingⅣNi-hard cast iron with lateritic nickel ore and chrome ore by one-step method.
