It has been difficult to get an analytical solution for temperature distribution in a solidifying and cooling process in a mold of continuous casting machine, because of multi-layered heat resistance between solidification front and water cooling surface of a mold ; solidified shell/ melt or solidified powder/ air gap/ mold coating/ mold metal and cooling water. Numerical methods, which are inconvenient to get a perspective of the total system, have been the only measure to analyse processes. The object of this research is to present a new general method to analyse a mold cooling system. The authors proposed a new concept "quasi-steady state", and defined a new standard function "cast function" as a solution of a linear heat flow model. They established a new precise general method to analyse a mold cooling system. As a result it has become possible to express explicitly temperature at arbitary location and time in the casting and cooling system. They also made a comparison among this method and other model methods.
