Product Description
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.
