Description
Introduction
ZHENJIN REFRACTORIES founded in 1985. It is a manufacturing enterprise integrating research and development, productions, sales, international trade and technical services. Refractory products and services for cement, lime, non-ferrous, glass, building materials and metallurgical industries.
Directly bonded magnesia-chrome bricks are refractory materials manufactured by special processes such as high-grade magnesia, chrome concentrate, and increased firing temperature. Due to the small number of silicate phases and the large number of secondary spinels, the silicate phases become islands, and there are "direct bonds" between periclase-perclase and periclase-chromite. Direct bonded magnesia-chrome bricks are made of high-purity magnesia, chrome ore, and chrome concentrate, which are formed by high pressure, dried and fired at high temperature.
Directly bonded magnesia-chrome bricks have low impurity content, high bulk density, good slag resistance, strong corrosion resistance, refractoriness under load high, and good thermal shock resistance against rapid cooling and rapid heating.
Direct bonded magnesia-chrome brick is a refractory product made of high-purity magensia and chrome concentrate as the main raw materials.
