The results indicated that increase of load inclination causes increase of plate sinkage and a decrease of sand bearing capacity.
结果表明，随着载荷倾角的增大，平板沉陷量增加，沙土承载能力降低。

The growing thermal load of green sand, the quicker recirculation times and the increased requirements on the quality of molding material make new demands on the molding sand preparation.
潮模砂日益增长的热负荷，更快的循环时间以及对造型材料质量要求的提高，对型砂制备提出了更高的要求。
