Our products
Six refractory systems for the induction furnace.
German refractory technology, made for Indian foundries and steel plants — from neutral lining mass to ladle castables, coil grout and lining tools.
DFP India manufactures a complete range of refractory materials for coreless induction furnaces, foundries and steel plants: neutral ramming mass, fused and natural silica ramming mass, ladle lining castables, coil grout, insulation and lining tools. As the official channel partner of Dörentrup Feuerfestprodukte — the German firm that pioneered neutral lining and liquid sintering for induction furnaces in 1901 — DFP India was the first to bring Alumina Spinel neutral ramming mass and liquid sintering to India. Every product is ISO 9001:2015 certified and validated batch-by-batch in an in-house QC lab.
