The naturally silica-feldepar sand found at XiChang is graing and open -air sand source Which is first found since the foundation of our republic in 1949.Itd's fine sand for cast iron. It may be used to replace both expeneive silica and low grade bonded sand. The test proves that this sand may meet the high gualified silica-feldepar sand for machine standard ( JB 435-68 ) 2S

西昌天然石英—长石砂是我省建国37年来第一次发现的颗粒状露天砂源,是一种优良的铸铁用砂,既可取代高昂的石英砂,又可取代低品位的粘土砂,经过鉴定,符合机标(JB435—68)2SC级石英—长石砂标准。

本文对我国西北地区新近发现的铸造原砂——宁夏青铜峡市广武乡的石英长石砂的资源情况、性能指标、初步应用情况做了简要的介绍。

There is a open sand mine with large recoverable reserves discovered in Xichang,Sichuan Province. It is demonstrated that the Xichang sand has a quartz - feldspar mineral composition,□-○ shape,Low mud ingredient,converged grain demension,and satisfactory technical properties in foundry production. Each index meets the national standard, JB435 -63/2SC,Exploitaltion of the sand mine will greatly benefit the foundry industry in Sichuan province.

西昌砂的矿物组成为石英—长石砂、形貌如□○砂。原砂含泥量低,粒度集中,各项指标达到JB435—63的2SC标准。该砂经生产性试验证实具有良好的铸造工艺性能,是我省较理想的铸铁生产用砂。该砂砂源为露天砂矿,储量大,它的开发对改善我省铸铁用砂,提高铸铁件质量有重要的现实意义。
