In slab moulds the cooling water flows in notches which are machined into the copper body. Therefore, the heat transfer from the hot side of the copper body to the cooling water is two‐ or three‐dimensional. But usually the heat transport is taken to be one‐dimensional and is computed using an average value for the copper wall with the water flowing in a slit parallel to the wall. This simplification is not very satisfactory. In the present study the three‐dimensional heat flow in a slab mould has been computed with an exact numerical model and the resulting heat transfer coefficient for heat flow from the hot copper side to the bulk of the cooling water is compared with that of three simple engineering equations.
