Abstract
In the production equipment for a precipitation hardened alloy strip, a solution treatment unit includes a heating chamber provided to heat the material alloy strip having a precipitation hardening alloy composition to a temperature of not lower than a recrystallization temperature but not higher than a melting point, a cooling chamber located adjacent to the heating chamber, and a pair of cooling rolls incorporated in the cooling chamber to hold therebetween and cool down the material alloy strip heated in the heating chamber. This production equipment can quench the material alloy strip to form a solid solution supersaturated with precipitation hardening elements and thereby forming a precipitation hardened alloy strip having a good shape and a favorable surface condition.
