摘要
湿型铸造因其生产方式简单、成本低、效率高,铸铁件生产占有率达80%左右。据统计,约80%的铸造缺陷源于型砂因素。随着环保法规的颁布和自动化、高密度造型线的广泛应用,对造型材料的综合性能提出了更高的要求。含煤粉的粘土砂因其有害排放超标,环境污染大,无法满足新形势下铸铁件的生产需求。企业急需打破常规,寻找一种可替代煤粉砂的新型环保造型材料,以期最大限度地提升我国铸铁件的生产技术水平和产品质量。“铸元素”作为一种新型环保造型材料,具有优异的综合性能,在铸铁件生产领域有着广阔的应用前景。
Because of its simple production mode,low cost and high efficiency,the production share of cast iron reaches about 80%.According to statistics,about 80%of casting defects are due to molding sand factors.With the promulgation of environmental laws and regulations and the wide application of automation and high density molding lines,higher requirements have been put forward for the comprehensive performance of molding materials.Clay sand containing pulverized coal can not meet the demand of cast iron production under the new situation because of its harmful discharge exceeding standard and environmental pollution.The enterprise urgently needs to break the routine and find a new environment-friendly molding material which can replace pulverized coal sand,in order to maximize the improvement of the production technology level and product quality of cast iron in China.As a new environment-friendly molding material,‘cast element’has excellent comprehensive properties and has a broad application prospect in the field of cast iron production.
