摘要
铸铁湿型砂中煤粉的主要功能之一是形成光亮碳。测定光亮碳要求使用专门仪器设备和按照严格的测试技术。介绍了国际铸造学会规定的光亮碳测定方法。在实际生产中，形成光亮碳并不是防止铸铁件表面粘砂唯一的措施，有些不生成光亮碳的材料也具有类似功能。
Forming lustrous carbon is one of the main functions of coal dust in cast iron green sand. In order to get precise result of lustrous carbon determination, specialized apparatus and consummate test skill are indispensable condition. The testing method provided by CIATF is presented. In Practice, the forming of lustrous carbon of green sand is not the only way to prevent sand burn-on of iron castings, several non-lustrous carbon materials have the similar function as well.
