Refractories

Find refractory materials solutions for fireplaces, kilns, electrical furnaces and foundries
By Robert Hill Some refractory companies specialize in niche areas while others carry a wide variety of refractories. These products, made for fireplaces, blast and electrical furnaces, kilns and other foundry essentials like roofs and ladles, provide protection from extremely high temperatures.

Refractory material comes in many forms, such as fire bricks designed for specific metals and temperatures, mortars and coatings offering resistance to slag and liquid metal penetration. When looking for refractory materials consider the following:

1. Select industrial refractories from a company with a wide selection of material, customer support and one-stop shopping.

2. Buy refractory material based on function and form, with discounts on large orders.

3. Work with refractory construction companies to design, build or provide work crews to get the job done.
