Chilled cast iron roll cutter

The chilled cast iron roll has a high hardness, a hard skin on the surface, and often accompanied by hard spots and cracks, which is very difficult to process. If cubic boron nitride and ceramic tools are used, they are more expensive and not resistant to impact. To this end, we use YG6A and YT726 fine-grained hard alloys with high flexural strength and good wear resistance, and adopt the machine clamp form to achieve better results.

Pipeline Insulation Rock Wool Pipes

Yu Ou Nuo rock wool pipe is a kind of rock wool insulation material which is mainly used in pipeline. It is made of natural basalt as the main raw material. After high temperature melting, it is made into artificial inorganic fiber by high-speed centrifugal equipment. At the same time, it is added with special binder and dust-proof oil, and then heated and solidified to make rock wool insulation pipes of various specifications and requirements. Rock wool pipe shell is a kind of resin rock wool insulation pipe shell and waterproof rock wool insulation pipe shell, which are made of selected diabase and basalt slag as the main raw materials, melted at high temperature and sprayed with special adhesive and waterproof agent in the process of high-speed centrifugation.
