我们于1965年1月开始在武汉柴油机厂试验推广硅素发热自硬芯砂,做195型柴油机汽缸体型芯等,特别在该年11月至1966年2月,在武汉可鍜铸铁厂代替马铁铸件:套筒板手、铡刀架、千斤顶等以及部分灰铸铁件:轧花机、三通阀等,从几克到1～2公斤的小型芯的桐油砂,满足工艺技术要求,保证质量,经济效果很显著,除了提高劳动生产率,减少运输周转,不要型芯烘房,节省燃料,特别是较每吨桐油芯砂的成本降低45～66%,很值得推广。国内已有工厂试验推广。要保证推广必须解决下述几个生产关键问题。下面就我们的工作谈谈初步的体会,供大家参考。
We started in January 1965 in Wuhan Diesel Engine Factory trial promotion of silicon-heating self-hardening core sand, making 195-type diesel engine cylinder core, etc., especially in November of that year to February 1966 in Wuhan, : Sleeve wrench, trowel, jack and some gray cast iron: ginning machine, three-way valve, from a few grams to 1 to 2 kg of small core tung oil sands, to meet the technical requirements, quality assurance, economic effect is very Significantly, in addition to raising labor productivity, reducing transport turnover, not core drying room, fuel savings, in particular, the cost per ton of tung sand core reduced by 45 ~ 66%, it is worth promoting. Domestic factory test promotion. To ensure that promotion must address the following key production issues. Here to talk about our preliminary experience of work for your reference.
