The effects of several factors on the setting expansion of a phosphate-bonded investment used in a steel casting ring were studied. The results show that the setting expansion under the conditions analyzed can be characterized only as a most unreliable means to partly compensate for the solid thermal contraction of casting alloys in a precision-requiring technique.
研究了几种因素对用于铸钢圈的磷酸盐粘结包埋材料凝固膨胀的影响。结果表明，在所分析的条件下，凝固膨胀只能被视为一种极不可靠的手段，用于在精密铸造技术中部分补偿铸造合金的固态热收缩。
