General Information
As the main refractories for coke oven, the quality is the key of energy saving, high efficiency, environmental and time of usage on coke oven. Over the years, We has been provided high-quality silica bricks for steel plants at Nagoya, Muroran and Oita of Nippon Steel and the products quality have been proved world-class products.The excellent performance silica brick has the following characteristics. The low creep, high refractories under load and low residual quartz contents, silicon bricks for hot stove of our company has been successfully applied to various types of hot stoves of major steel companies at home and abroad and the quality has been recognized by the clients. The silica bricks are the main fire-resistant material of coke oven. In order to keep its high quality, we take the best silica as raw material from Liaoning Shimen, Shanxi Wutaimountain, Henan Tiemen. With the multistage batching and best grain matching, our semi-manufactured goods are produced by the 300tons bricks pressing machine. The bottom,
Wall and top bricks are produced by 500tons bricks pressing machine. Every semi-manufactured and finished product-s are examined according to the national standard and marked it according to the tolerance.
Feature
Superior resistance to acids (including oxidizing)
Resistance to chlorine
Resistance to thermal shock and pressure changes
Low thermal and chemical expansion
