Sintered products collected by Calcinor are distributed worldwide.
Calcinor provides a range of high purity sintered products, obtained through a two-step thermic process; an initial calcination or roasting, followed by briquetting, and later sintering
Ca Mg (CO3)2 + Tª (~1000ºC) → CaO MgO calcined + 2CO2
CaO MgO calcined + Tª (>2000ºC) → CaO MgO sintered
Through this technique, we are able to obtain high purity and excellent refractory products. Following a manufacturing process, the company Refractarios Kelsen, now belongs to Calcinor, preparing sintered products using a great variety of refractory material both shaped and unshaped for use in the steel and iron industry.
Sintered dolomite is a product obtained through high temperatures. The combination of its chemical quality together with the production process used, gives high refractoriness. Thoroughly used in the obtainment of refractory materials in mass and brick form, for its use in the steel and iron industry.
REFRADOL, obtained through the continuous development of activities of R+D, is a sintered dolomite based of high density, which is subjected to an additional industrial process conferring a great hydration resistance, and becomes suitable for its use in gunning plains for ladles and electric arc furnace.
