Abstract
A process for the desulfurization or nodularization of a ferrous melt which comprises introducing into the melt at least one reducing composition formed between an element of one of the groups I, II and III of the Periodic Table of elements (except for hydrogen and boron) and at least one element selected from the group which consists of hydrogen, boron, carbon, silicon, nitrogen and phosphate or a combination of one of them with sulfur, and at least one composition reducible by the reducing composition of at least one metal selected from the group which consists of the alkaline metals and the metals of groups II and III of the Periodic Table. The mixture is of a composition within the portion of the phase diagram of the mixture corresponding to a single homogeneous liquid phase in the region of temperatures above the melting point of the alloy to be treated. The treating composition is used in the form of a homogeneous liquid or a substantially homogeneous solid which melts at contact with the alloy.
