本文首先论述了水玻璃砂在我国铸钢件生产中的地位及再生的必要性,简要地介绍了近期诸发达工业国家,再生设备的种类和性能,然后论述了由沈阳铸造研究所开发我厂生产的S544—Ⅱ型干法强力水玻璃砂再生机的再生原理及其它特点,并围绕水玻璃砂再生工艺的要求、就S544—Ⅱ型干式再生机的再生效果,再生后再生砂与新砂在生产中的比较试验进行生产验证结果,进行了论述并得出了水玻璃砂可以采用干法再生的结论。
This paper first discusses the status of sodium silicate sand in the production of steel castings in our country and the necessity of regeneration. It briefly introduces the types and properties of recently developed industrial countries and regenerative equipment, and then discusses the development and application of sodium silicate sand produced by Shenyang Foundry Research Institute Production of S544-Ⅱ-type dry power sodium silicate regenerator regeneration principle and other characteristics, and around the water glass sand regeneration process requirements, on the S544-Ⅱ-type dry-regeneration machine regeneration effect, regeneration of recycled sand and new sand In the production of comparative test production verification results were discussed and concluded that the sodium silicate sand can be used dry regeneration conclusion.
