硅砂在冶金、铸造行业中,作为耐火材料及造型材料中的主要原料占有重要的地位,它与铸件的质量、成本、生产效率和劳动条件都有着密切的关系。 我省部份地区轻工、化工、冶金及机械制造业中使用的硅砂不少是从外省运来的,其运输费用比原砂成本往往高3～4倍,直接影响到产品的成本。地质勘探部门于1982年底在赣州市郊峰山地区发现了以二氧化硅为主的大型硅石矿,硅石平均品位达96.886％,可作硅砖硅铁等陶瓷、冶炼工业原料,现已
In the metallurgical and foundry industries, silica sand plays an important role as the main raw material in refractory materials and modeling materials. It has a close relationship with the quality, cost, production efficiency and working conditions of castings. In some areas of our province, many of the silica sand used in light industry, chemical industry, metallurgy and machinery manufacturing are shipped from other provinces. The transportation cost is 3 to 4 times higher than the cost of raw sand, which directly affects the product cost. At the end of 1982, the geological prospecting department found a large-scale silica ore mainly composed of silica in the Fengshan area on the outskirts of Ganzhou. The average grade of silica reached 96.886%. It can be used as raw material for ceramics and smelting of ferrosilicon,
