JSC “Podolsk Refractories” is a leading producer of fused cast products for the glass sector and steel industry in Russia and has more than 100 customers. This strong position covers all segments of the glass industry: besides close contacts with container, medical and float glass producers, JSC “Podolsk Refractories” has excellent experience in the special glass segment.
JSC “Podolsk Refractories” produces refractories mainly for the Russian and CIS glass markets. The site is equipped with two electric arc furnaces, producing alumina-zirconia-silica (AZS) and alumina fused cast products. The main product line consists of fused cast AZS blocks called “BK” (manufactured according to the Russian standard GOST 23053-78). These materials are mostly used by the glass industry to construct side-walls, bottom and superstructure of glass melting furnaces. This product group includes BK-33, BK-37, and BK-41 grades containing 33 wt.%, 37 wt.%, and 41wt.% zirconia, respectively. The second product line are alumina (corundum) fused cast products termed KEL which are used in the glass industry as well as in the ferrous and nonferrous metal sectors. The grade KEL-93 containing 93 wt.% alumina is used as lining of holding zone bottoms of reheating furnaces. The grade KEL-95 containing 95 wt.% alumina is used in glass melting furnaces for lining the working ends and feeder channels. The third product group includes high-temperature mixes: dry zircon-containing concretes of grades “BZ-5” and “BZ-0,5”, refractory AZS mortar “Zirasil”, crushed AZS “KBO-1”.
