结合CO_2“七○”砂的使用情况,提出了新型有机酯水玻璃砂代替CO_2水玻璃“七○”砂的初步方案,着重研究有机酯水玻璃砂在电炉车间使用的可行性,以及工艺、性能等对铸件质量成本的影响。
Combined with the use of CO 2 “70” sands, a new scheme of replacing the “70” sands with CO.sub.2 water glass was proposed, and the feasibility of using the organic ester water glass sands in the electric furnace workshop was also studied. Performance and other effects on the quality and cost of castings.
