Casting Rise Pipe Block for Coke Oven with Integral Structure developed by YDRM is mainly made of cordierite-mullite-fused-quartz composite material, which overcomes the performance limitation of traditional products. It has the characteristics of excellent thermal shock stability, high strength, small thermal conductivity, good permeability resistance and corrosion resistance. The advantages of the products are as follows:
The product adopts integral casting production, and is directly installed by several annular parts in the later stage, which greatly reduces the difficulty of installation, avoids the structural instability defects of traditional products and improves the engineering efficiency.
High temperature ceramic glaze is applied on the working face, and tar and graphite are not easy to adhere, which greatly reduces the daily maintenance workload of industry customers.
Due to the characteristics of the new material, the outer wall temperature of the rise pipe is greatly reduced and the energy consumption is reduced. At the same time, due to the stable performance of the product, the service life is extended, and the economic benefits are prominent.
