我們車間学习了兄弟厂的經驗,同时在生产上不断加以改进和提高,目前很大一部分中大型鑄件都采用了泥型鑄造,这样不但大大提高了单位面积产量,同时解决了烘窑、吊車和砂箱不足的困难。泥型材料 1.造型材料的配合成分:造型材料是由缸砂、紫泥、老煤粉、白铅粉、黑铅粉等組成。其中除缸砂需自己加工(軋破后,用每吋6眼篩子过篩,再除去缸砂中的細末)外,其余在市上都可以买到。
Our workshop has learned the experience of brother factory, at the same time in the continuous improvement and improvement of production, a large part of the large castings are used mud casting, it will not only greatly improve the yield per unit area, at the same time solve the drying kiln, crane and The problem of insufficient sand box. Mud material 1. With the molding material composition: molding material is cylinder sand, purple clay, the old pulverized coal, white lead powder, black lead powder and other components. In addition to the cylinder to be processed by their own (after crushing, with 6 screens per inch sieve, and then remove the fine sand cylinder), the rest are available in the market.
