The invention provides a high-carbon ferrochrome smelting method and a product. According to the high-carbon ferrochrome smelting method, a magnesium-containing aid is used; a Mg component is added to raw materials and serves as a slag forming constituent; more importantly, the Mg component can adjust the proportions of Mg and Al (chrome iron ores contain Al) in the raw materials, effectively improves the reduction effect in a smelting process and can improve the quality and performances of the obtained product. The high-carbon ferrochrome smelting method has the beneficial effects that the process is simple, the manual labor intensity and the loss are low, little smoke is generated and is easy to collect and treat, and the environmental protection requirements can be satisfied. The high-carbon ferrochrome product is low in cost and easy to obtain and has excellent quality and performances.
