Abstract
A refractory article having a support structure including a first plurality of posts coupled by a first member; and a second plurality of posts substantially parallel with the first plurality of posts, the second plurality of posts coupled by a second member, wherein the support structure has a height, H, and wherein the first and second members are positioned between 0.3H and 0.7H. In another aspect, the support structure has a height to width ratio of at least 1.5, a stiffness factor of no greater than 100 mm, and a solid to open volume ratio of no greater than 5%. In another aspect, the support structure has a weight of no greater than 1200 kg, a stiffness factor of no greater than 100 mm, and a solid to open volume ratio of no greater than 5%.
Claims19
A refractory article, comprising:
- a support structure comprising:
- a height, H;
- a first plurality of posts coupled by a single first member positioned between 0.3H and 0.7H, wherein the first member is disposed within an aperture of each of the first plurality of posts and in direct contact with a portion of one or more posts of the first plurality of posts;
- and
- a second plurality of posts substantially parallel with the first plurality of posts, the second plurality of posts coupled by a single second member positioned between 0.3H and 0.7H, wherein the second member is disposed within an aperture of each of the second plurality of posts and in direct contact with a portion of one or more posts of the second plurality of posts,
- wherein at least one of the first member or second member is not secured to the apertures but instead permitted to move therein, and
- wherein each of the first and second plurality of posts consists of a monolithic piece.
A refractory article, comprising a support structure comprising:
- a height, H;
- a first plurality of posts coupled by a first member positioned between 0.3H and 0.7H, wherein the first member is disposed within an aperture of each of the first plurality of posts;
- a second plurality of posts substantially parallel with the first plurality of posts, the second plurality of posts coupled by a second member positioned between 0.3H and 0.7H, wherein the second member is disposed within an aperture of each of the second plurality of posts, wherein at least one of the first member or second member is not secured to the apertures but instead permitted to move therein;
- a plurality of third members positioned at a relative height from 0.7H to 1H, wherein each third member couples a post of the first plurality of posts and a corresponding opposite post of the second plurality of posts,
- wherein:
- the first plurality of posts are devoid of another member spanning there between at a height between the first member and the plurality of the third members;
- and
- the second plurality of posts are devoid of another member spanning there between at a height between the second member and the plurality of the third members.
