Abstract
A deflector element 3,13 is provided, in order to improve temperature interface control with respect to directional solidification of a component casting. This deflector element 3,13 is formed during the mould making process and is arranged to be positioned with respect to a part 6 of a principal mould formation 2,12 within which the final cast component is produced. The deflector element 3,13 ensures a uniform temperature throughout the component cross-section relative to other parts of the component as it is solidified.
Claims21
A method of component casting comprising forming a mould with a displaced deflector element adjacent to a part of a principal mould formation whereby the deflector element controls the rate of heat loss from that part of the principal mould formation.
A method as claimed in any preceding claim wherein the deflector element is coated for improved radiation with a low emission material.
A mould for component casting comprising a principal mould formation and a displaced deflector element immediately adjacent a part of the principal mould formation to control in use the rate of heat loss from that part of the principal mould formation.
A method of component casting substantially as hereinbefore described with reference to the accompanying drawings.
A mould substantially as hereinbefore described with reference to the accompanying drawings.
Any novel subject matter or combination including novel subject matter disclosed herein, whether or not within the scope of or relating to the same invention as an˜ of the preceding claims.
