CS-POTS
We manufacture small fireproof pots, used in analyzers, precisely measuring the contents of carbon and sulphur in various materials, of ceramic material, containing 80% of SiO2.
MULLITE SIEVES
The ceramic sieves are used for removing larger impurities in melted materials at the temperatures up to 1700O C. Their forms and dimensions meet the customers' requirements. We can achieve medium tolerances according to DIN 40680.
FOAMED CERAMIC FILTERS
The foamed ceramic filters are manufactured on the basis of SiC. They are used in metallurgy for removing nonmetallic inclusions, which are the most frequent cause of faults on castings. The characteristic meshed structure provides a large specific surface and high open porosity, allowing high filtering effect. The melted metal, when passing through the filter, flows in a characteristic meandering pattern, enabling excellent filling of moulds, and elimination of even the smallest inclusions that are absorbed by the inner surface of ceramic pores.
Temperature tests with melt: T = 1420 ─ 1450oC min. 30s
T = 1450 ─ 1500oC min. 45s
Filters’ dimensions and throughput depend on the quantity of the filtered melt. Standard shapes are square, rectangular and round, whereas their dimensions range from 40mm to 100mm, with heights of 15mm and 22mm.
