Present status of refractories for ferro-alloy industry

Abstract

With the growth of steel plant and increased production of alloy and special steels, the demand for ferro-alloys has increased. The present paper describes the refractory practices for producing ferro-alloys. In the production of low carbon ferro chrome products in the reaction ladles very high temps. are involved. The refractories used in these furnaces are severely eroded and life of the refractories is much low. The paper discusses the typical reasons of refractory wear patterns in these furnaces. The paper suggests suitable refractories for the produc-tion of ferro-alloys like ferrochrome, ferro manganese, ferrosilicon and also low carbon ferro chrome products.
