摘　　要：选择合适的熔融试剂,使用熔融玻璃片法将试样与熔剂按照一定配比在高温下进行熔融,以消除矿物、粒度效应的影响,应用钴内标法对全铁进行分析。实践证明此方法可行,能够满足生产的需要。After choosing the appropriate melting agent, by using fusedglasspellet method, the sample and melting agent were fluxed according to certain proportion under the high temperature to eliminate the influence of mineral and size effect, and then the total iron was analyzed by using cobalt internal standard method. The practice showed that this method was feasible and could satisfy the production need.
