Abstract
An apparatus for moving a stream of molten metal comprising a pumping member, a housing at least partially enclosing the pumping member, a power device seated on a support, a shaft connecting the power device and the pumping member. At least one post is disposed between the support and the housing. The post includes an elongated rod surrounded by a heat resistant outer member. The rod includes a first end connected to the support and a second end secured within a cavity in the housing.
Claims15
An apparatus for moving a stream of molten metal comprising:
- a rotatable pumping member;
- a housing at least partially enclosing the pumping member;
- a power device seated on a support;
- a shaft connecting the power device and the pumping member;
- and
- at least one post disposed between said support and said housing, said post comprising an elongated alloy rod surrounded by a heat resistant outer member, said rod having a first end connected to said support and a second end including a shoulder secured within a cavity in said housing.
An apparatus for moving a stream of molten metal comprising:
- a rotatable pumping member;
- a housing at least partially enclosing the pumping member,
- a power device seated on a support;
- a shaft connecting the power device and the pumping member;
- and
- at least one post disposed between said support and said housing, said post comprising an elongated alloy rod surrounded by a heat resistant outer member, said rod having a first end connected to said support and a second end secured within a cavity in said housing, wherein said second end of said rod extends partially through said cavity and is threadedly attached to a graphite, refractory or ceramic cap to secure said post to said housing.
A molten metal post comprised of an elongated graphite, refractory or ceramic member including an end having multiple, axially non-aligned, circular sections formed to create a cam lock arrangement within a bore of a housing.
A molten metal shaft and impeller combination, said shaft comprising a cylindrical body having an end with a plurality of axially, non-aligned circular sections, said circular sections wedged into a plurality of connecting circular bore openings in said impeller.
