摘　　要：对四种不同配方的天然粘土砂,分别进行了型砂的成型性试验和对HT150的浇注试验。首先,用这四种天然粘土砂分别进行了手工造型,通过工人的经验和造型结果的综合评定,找出最易成型的配方。其次,对造型良好的铸型进行浇注试验,通过分析铸件的表面质量(粘砂和粗糙度)和型砂烧结壳,得出最佳的铸造工艺,最后获得天然粘土砂铸造工艺的壁厚适应范围。Tests of moldability and pouring of HT150 cast iron were carried out on natural clay-bonded sand with four different formulas. Firstly, the formula of natural clay bonded sand with the best moldability was selected according to the former＇s experience and the results of molding. Then, the best casting process was achieved by analyzing iron casting＇s surface quality （sand burn on and roughness） and the sintering shell of the molding sand. Finally, the proper thickness range of iron casting adapt for natural clay bonded sand casting process was obtained.
