Whilst hot charging offers obvious benefits in terms of energy saving, the possibility of coarse inhomogeneous microstructures may lead to lower strength and toughness in the finished product. In order to evaluate the effect of hot charging on properties, this report describes how special moulds were used to simulate continuously cast slab and how a method was established to provide hot connection between the casting bay and the reheating furnace. Steels of CMnAl, CMnAlNb and CMnAlNbTi compositions were rolled after hot clamping and soaking at various temperatures; their properties are compared with those of conventionally processed steels. The results indicate that CMnAl steels do not suffer marked property deterioration when charged within the transformation range.
