Abstract
According to another embodiment, a molten metal filter having two opposed plates is provided. At least one hollow elongated member comprised of a porous refractory material is attached at a first end to a first end plate and at a second end to a second end plate. The first end plate has a passage extending through a width of the first end plate and a ledge that receives the first end of the elongated member. The second end plate has an opening receiving the second end of the elongated member. The opening passes through the width of the second end plate and is dimensioned to be larger than a circumference of the elongated member.

A molten metal filter comprising two opposed plates and at least one hollow elongated member comprised of a porous refractory material attached at a first end to a first end plate and at a second end to a second end plate, the first end plate having a passage extending through a width of the end plate that receives the first end of the elongated member, the second end plate having an opening receiving the second end of the elongated member, wherein the second end plate includes an element configured to accommodate thermal expansion of the elongated member.
A molten metal filter comprising two opposed plates and at least one hollow elongated member comprised of a porous refractory material attached at a first end to a first plate and at a second end to a second plate, the first plate having a passage extending through a width of the plate and a ledge in the passage that receives the first end of the elongated member, the second plate having an opening receiving the second end of the elongated member, the opening passing through a width of the second plate, said opening being dimensioned to be larger than a circumference of the elongated member.
A molten metal filter comprising two opposed plates and at least one hollow elongated member extending therebetween, the elongated member and at least a first of the plates being comprised of a porous refractory material, said porous refractory material plate having an opening receiving an end of the elongated member, said opening passing through a width of the plate, wherein an entire surface of the plate facing the elongated member includes a cement coating or wherein a periphery of the surface includes a cement coating and a middle portion of the surface is uncoated.
