Xinmi Zhenfa Refractory Materials Co., Ltd. is located in the Micun Industrial Development Zone in Xinmi City, at the foot of Mount Song, adjacent to the Beijing-Guangzhou and Lanzhou-Lianyungang railways. Its convenient transportation and complete communication facilities, rich in high-quality silica, bauxite, coal and other resources with excellent quality, provide unique conditions for the development of refractories.
Founded in the 1990s, our company mainly produces siliceous refractories. And over the 20 years of development, the company has always adhered to the principle of “Quality First, Customer First”, continuously improving production processes and updating equipment according to market needs, integrating scientific research and development. We have also established long-term and stable technical cooperation relationships with scientific research institutions such as the China Building Materials Academy Co., Ltd., Sinosteel Luoyang Institute of Refractories Research Co., Ltd., and The Chinese Ceramic Society, which enhanced our internal development capabilities.
Our products mainly include high-quality 96# silica brick, high-density and low-porosity silica brick, zero-expansion silica brick, calcium-free silica brick and various amorphous refractories for glass furnace. We mainly serve the glass industry, and the high-density and low-porosity silica bricks developed and produced by us is a solution for oxygen-fuel combustion and petroleum coke furnaces! Our products are best-selling in provinces, cities and autonomous regions across the country, and are exported to the United States, Japan, Russia, Southeast Asia and other countries.
