依据化学成份,废钢中除 Fe 和 C、Si、Mn、P、S 五大元素外,尚有一种或多种其它合金元素的废钢叫做合金废钢。废钢中 Mn、Si 的含量超过一定量时也叫合金废钢。在合金废钢中,合金元素的总含量<5%的,谓之低合金废钢;合金元素总合量为5～10%的,谓之中合金废钢;合金元素总含量在10%以上的,谓之高合金废钢。合金废钢中一般含有的合金元素有Cr、Ni、W、V、Ti、B、Nb、Co等。这些合金元素来源于炼钢和铸钢中的
According to the chemical composition, in addition to the scrap of Fe and C, Si, Mn, P, S five elements, there are one or more other alloying elements of scrap steel called alloy scrap. Scrap in the Mn, Si content exceeds a certain amount also called alloy scrap. In the alloy scrap, the total content of alloying elements <5% of the low alloy scrap; the total amount of alloying elements 5 to 10%, that the alloy scrap; the total content of alloying elements in 10% or more, that The high alloy scrap. Alloy scrap generally contain alloying elements Cr, Ni, W, V, Ti, B, Nb, Co and so on. These alloying elements come from steelmaking and cast steel
