摘要
选用酸式磷酸盐为粘结剂,炼钢还原碱性渣为促凝剂,用正交试验方法确定了磷酸盐自硬砂的最佳工艺配方,并进行了性能测试及初步的生产实验,表明具有一定的经济效益。
The optimum composition of the selfhardened phosphate sand has been determined through the orthogonal experiments utilizing the acid phosphate as cohering agent and the alkaline slag as solidifying accelerant.The product features\+′ tests and the small quantity productoin show that this product is of great economic significance.
