Cast Basalt

Cast Basalt

Cast Basalt is a mineral of exceptionally high abrasion resistance, unlimited resistance to moisture, high compressive strength and resistance to virtually all acids and alkalis and is completely corrosion free. Cast basalt is produced by melting selected natural-broken into sizes of 20-50 mm in shaft furnaces at temperatures around 1300º C followed by casting at which the melted basalt forms uniform, pherolithic crystals, hence producing its typical physical properties in particular its exceptional hardness and wear-resistance. Cast basalt reaches a value of hardness of 8 (min) on the Moh’s hardness scale.

Cast Basalt is the wear-protective material most frequently used, Offering an outstanding price/efficiency ratio and allowing a very economical preventive wear protection. Due to its extreme hardness. Cast  basalt is used for components subject to high abrasion or scuffing.However, it is marked by a certain sensitivity to impacts. Under normal service conditions, cast basalt withstand temperatures up to approx. +350º C or – 40º C.

Cast basalt products are manufacturedas tiles, formpieces, pipes and segments. Straight pipes are spun-cast available for nominal bores of 32 to 600mm with the wall thickness ranging from 20 to 30m and a standard length of 500 mm. Smaller nominal bores of straight pipes, pipe segments for radii of 400 to 3000 mm of various angles as well as special formpiece linings are predominantly sand-cast.

Cast basalt lined piping is exceptionally wear-resistant and is applied whenever highly abrasive materials are to be conveyed pneumatically or hydraulically through pipelines, such as compound material, coal, coal dust, coke, fly-ash, furnace dust, cement, lime, fine ores, slag, sand and other coarse or fine-granulated abrasive material.
