球化剂的种类和性质 可以或成能发生球化作用的元素据现在所知有镁、钙、铈、锶、钡、锂、钠、钾、碲、硫等。 铈是一种稀有金属,1947年以前是以铈乍球化齐,其球化效能很低,且价钱昂贵,同时还要受到碳分矽分的限制,因此铈在球化剂中的地位较低。 锶是一种碱土金属。 钡有毒。据 Types and Properties of Nodulizer The elements that can or may undergo spheroidisation are now known as magnesium, calcium, cerium, strontium, barium, lithium, sodium, potassium, tellurium, sulfur and the like. Cerium is a rare metal, before 1947 is cerium first ball Qi Qi, the ball of its very low efficiency, and expensive, but also subject to the carbon divider limit, so the status of cerium in the nodularizer low. Strontium is an alkaline earth metal. Barium is toxic. according to
