Resistance of Fused Cast Basalt

The manufacture of the fused cast basalt was pioneered in West Germany about 60 years ago. Fused cast basalt, also known under the registered trademark ABRESIST, is abrasion and corrosion resistant. The material is used worldwide in virtually all industries to protect equipment from the destructive forces of wear. 

The following tests were made to demonstrate the resistance of the fused cast basalt to various bases. The values cited are average values. 

Fused cast basalt tias an established place in the field of chemically resistant masonry. These linings will work particularly well when the chemical attack is combined with the abrasive action of sharp, hard particles. Worldwide, many in-... 

ABRESIST is a mineral material, a silicate with a high compressive strength and a high modulus of elasticity, with extreme resistance to abrasion, whereby a certain sensitivity to impact is also present. In addition to its abrasion resistance, fused cast basalt does not rust and thus always presents a smooth sliding surface. Even after an idle period in a wet transportation system, clogging and plug formation are largely eliminated. 

The foundry technology does not admit the manufacture of dimensionally precise products of complex shapes. For this reason, sintered basalt technology has been developed for the manufacture of nozzles, drawing dies, dies for auger brick machines, etc., where the materials exhibit a resistance to abrasion still higher than that of cast basalt. The fused basalt powder is mixed with a plasticiser and pressed the pressings are sintered in an electric tunnel kiln at 1120 to 1140 C. 

Fusion-cast Basalt. An abrasion-resistant material made by fusing natural basalt and casting the molten material into moulds to form blocks. The hardness is 8-9 Mohs crushing strength, 500 MNm-2. These blocks can be used for industrial flooring and for the lining of bunkers, chutes, and other equipment where abrasion is severe.
