Developing basic high-performance products for furnaces in the nonferrous metals industries

Increasingly stringent requirements in the service life of refractory linin gs for furnaces used in the nonferrous metals industry have necessitated th e development of basic high-grade products to meet demands on wear resistan ce. The use of a new generation of high-density brick types has substantial ly enhanced key physical properties, such as erosion and corrosion resistan ce. A practice-oriented testing method has been developed to measure struct ural flexibility, a parameter that plays an important part in many applicat ion. By optimizing these brick properties, products that withstand even hig h thermomechanical stress have been successfully manufactures.
