Cast Basalt is a mineral of exceptionally high abrasion resistance, unlimted 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 basalt broken into sizes of 20-50 mm in shaft furnaces at tempreatures around 1,300C, following by casting at which the metled basalt forms uniforms pherolithic crystals hence producing its typical physical propertics, in particular its exceptional hardness and wear-resitance.
Cast basalt reaches a value of hardness of 8( min ) on the Moh’s hardness scale. for comparision : the highest value10is only attained by dimonds. by virtue of these properties,the silicate cast basalt provides outstanding protection against abrasion and scrubbing.
however, it is marked by asertain sensitivity ti impacts.Under Normal services conditions, cast basalt withstands tempratures up to approx.+ 350C or-40C. However Cast basalt sholud not be subjected ti temprature shocks.
Sizes: Cast basalt produces are manufactured as tiles, from pieces and segments. straight pipes are spun-cast, available for nominal bores of 32 to 600 mm with the wall thickness ranging from 20 to 30mm and a standard lenght of 500mm. Samller nominal bores of straight pipes, a pipe segment for radill of 40 to 3,000mm of vatrious angles, as well as special formpiece linings are pre dominately sand-cast. The standard wall-thickness is 20mm. depending on the respective quantity, steel moulds can also be used, the wall thickness in those cases usually being 30 to 40mm.
Wear Resistant Fused Cast Basalt Lining Material
Cast Basalt is made from special quality natural basalt. The basalt is melted in shaft furnaces at 1,300°C and then poured into the desired forms. Cast Basalt is produced in form components. Essentially, this means sheets and pipe components.
One of the most important processes in the production of Cast Basalt is the subsequent tempering during which the Cast Basalt forms a uniform crystalline structure that guarantees its high hardness and wear resistance.
Due to its bargain price/performance ratio, Cast Basalt is a material often used in tribology protection. In addition to its wear resistance, Cast Basalt is characterized by its singular resilience with regards to almost all acids and bases.
Cast Basalt surfaces remain permanently smooth and even while in use and thus offer the advantage of little caking.
