摘要
研制了测定铸铁凝固期间电阻率变化的系统,测定电阻率的变化值,可以判断铸铁凝固期间新相的形成。实践表明该系统可以用来判定球墨铸铁的球化等级。
A system measuring the change of resistivity of cast iron during solidification was developed. The new phases formed during solidification can be judged by measuring the change of resistivity. The practice proved that nodular class of nodular cast iron can be determined by means of the system.
