Abstract: The explicit finite difference method is used to the quenching of CrNi steel, the relationship between surface heat transfer coefficients and temperature is determinated by means of solving the inverse problem of heat conduct equation.

Key words: finite difference method, quenching, surface heat-transfer coefficient, non-linear estimate method
