摘要： A boron alloying additive for continuous casting of boron steel having the desired hardenability without tundish nozzle blockage. The additive comprises 0.25-3.0% boron, 2.5-40% rare earth metals (RE), 6-60% titanium, and the balance iron. The additive may also contain silicon, calcium, manganese, and zirconium. In the additive the weight ratios of Ti to B and (Ti+RE) to B are 20:1-60:1 and 30:1-90:1, respectively.

摘要： Disclosed is a method of making stainless steel that has remarkable advantages over the electric-furnace practices now used. The method uses an oxygen furnace, yielding large savings in the time, capital investment, and labor required to produce a given quantity of steel. The practical difficulties that attend the use of an oxygen vessel to make stainless steel are overcome, principally by using a slag of high basicity ratio (3.5 minimum) operating the furnace so that the melt stays below 3100* F during most of the refining, and reducing the slag in a separate vessel, the contents of which are returned to the oxygen vessel.

摘要： The present invention provides a method for preparing ferrovanadium alloys based on aluminothermic self-propagating gradient reduction and slag washing refining. The method includes the steps of (1) performing aluminothermic self-propagating gradient reduction; (2) performing heat preserving and smelting to obtain an upper layer alumina-based slag and a lower layer alloy melt; (3) jetting refining slags into the lower layer alloy melt, and performing stirring and slag washing refining; and (4) cooling the refined high-temperature melt to room temperature, and removing an upper layer smelting slag to obtain the ferrovanadium alloys.
