一、低碳高强度铸铁的获得高强度铸铁是指其机械性能超过一般的铸铁。为了获得高强度铸铁,最普遍和最好的方法是设法使其获得珠光体基体并减少石墨的数量及改变石墨的分布和形状。为了达到上述的目的,最简单和最有效的方法是获得低碳铸铁。在冲天炉中为 First, the low-carbon high-strength cast iron to obtain high-strength cast iron refers to its mechanical properties than the average cast iron. In order to obtain high-strength cast iron, the most common and the best way is to try to get it pearlite matrix and reduce the number of graphite and graphite to change the distribution and shape. The simplest and most effective way to achieve this is to obtain low-carbon cast iron. In the cupola for
