摘要

Two custom-built Carbolite furnaces with provision for protective atmospheres are providing Howmet Exeter Castings with precisely controlled facilities for heat-treating industrial gas turbine blades. The company is one of the world's leading producers of complex investment-cast turbine airfoils. The components, usually produced from nickel-based super alloys, range in size from around 25mm to over 800mm in length and require heat-treatment in order to optimise their mechanical performance. Heat-treatment equipment is required to take account of the wide variety of component casting morphology now found in industrial gas turbines, with accurately controlled ramping, heating and cooling cycles a priority in order to ensure dimensional stability. The increasing use of more sophisticated alloys has also produced a need for tighter thermal tolerances during heat-treatment.
