Abstract
A method of lining a cavity, such as, for example, the head box for an ingot mold, comprising applying to the surface to be lined a lining of a self-supporting deformable fibre mat refractory composition and then exerting pressure on that lining so as to deform and conform it to the shape of the cavity.
Claims7
The method of lining an ingot hot top with a preformed liner comprising:
- forming a flexible mat by removing liquid from a slurry of a refractory composition including fibrous material and a suitable binder on a filter screen, removing said mat from said screen, disposing said mat around inside surfaces of said hot top and inserting an expansible deforming means within said mat and expanding said means to press said mat into conformance with the interior surfaces of said hot top, removing said expansible deforming means, leaving said mat adhered within said hot-top thereby forming a lining and allowing said lining to harden in place.
The method of claim 14 wherein the slurry contains a refractory filler.
