Quality Management

ZHENJIN REFRACTORIES has two lines of burnt basic bricks, one line of alumina-silica shaped refractory, as well as one line of unshaped refractory production. There are three super-high temperature tunnel kilns up to 1850℃, with the total capacity of about 100,000 tons/annual of various type refractories. ZHENJIN REFRACTORIES has long focused on technological innovation and modern equipment investment, automatic production of programming dosage, two hydraulic presses of 2500-ton. All the cement bricks have to pass the multi-functional finishing line, imported from Europe, in order to sort bricks beyond the tolerance, to stick card board and to mark brand.
