调查研究某铸造作业和采石作业生产性粉尘成分的元素含量。用扫描电子显微镜和X射线能量色散仪测定某铸造作业翻砂车间、造型车间、清砂车间和某采石作业生产性粉尘粒子的结构及各元素的百分含量。随着铸造用的砂粒结构向多面结构改变,其粉尘中各元素的百分含量也随浇铸、高温发生改变,氧、硅、硫逐渐减少,铝、钙、铁逐渐增多,生产性粉尘的粒子结构和元素成分发生变化。
Investigate the elemental content of a productive dust component of a foundry job and quarry job. The structures and contents of various elements of dust particles in a casting workshop, a modeling workshop, a cleaning workshop and a quarrying operation were determined by scanning electron microscopy and X-ray energy dispersive spectrometry. As the casting sand structure changes to multi-faceted structure, the percentage of each element in the dust also changes with the casting and high temperature, the oxygen, silicon and sulfur decrease, the aluminum, calcium and iron increase gradually, and the dust particles Structural and elemental composition changes.
