Process for smelting ferronickel from laterite-nickel ore through submerged arc furnace at high power

The invention provides a process for smelting ferronickel from laterite-nickel ore through a submerged arc furnace at high power. The process comprises the following steps: 1) crushing and screening raw ore, and mixing and burdening the raw ore after the raw ore is screened; 2) carrying out moisture pretreatment on the mixture through a drying kiln, and controlling the moisture of the mixture within a range of 23-26% to obtain dry ore; 3) uniformly mixing and burdening the dry ore through a burdening station, and conveying the dry ore into a rotary kiln to be calcined to obtain calcine; and 4)conveying the calcine into the submerged arc furnace for reduction smelting to obtain nickel-iron water. According to the process, on the premise that furnace body and electrode parameters are not changed, after a large-capacity transformer is replaced, the restriction that the power of the submerged arc furnace cannot be improved in the past is broken through, and therefore the condition for achieving high-power 33000 K
