Abstract

A liquid phenolic resin composition for use as a binder for a refractory article, the phenolic resin composition comprising a phenol formaldehyde resin, wherein the phenolic resin composition has a reduced vaporization percentage of phenolic compounds. The phenolic resin composition is used in refractory compositions comprising at least 50 wt. % of one or more refractory aggregate(s), based on a total weight of the refractory composition. There is also disclosed a refractory article, such as a brick, formed into a shape comprising said refractory composition and heating until the phenolic resin composition is at least 20% cured and having a green strength after curing at 170° C. for 5 hours sufficient for handling the solid without falling apart. Ladles for transporting and pouring molten metals can be made with an inner liner formed by stacking at least two bricks along the bottom and sides of a ladle shaped metal outer liner, and then heating the stacked bricks to a temperature sufficient to carbonize the resin thereby forming the inner liner of the ladle.
