     Refractory castables and other refractories can not combine very well with the metal shell of equipment in many working conditions. Due to the inconsistency of linear change and expansion coefficient, the refractory attached to the metal shell crack or fall off, so the high temperature equipment can not run normally.
     We focus on this situation and successfully develope nanoscale heat insulated wear sesistant coating, This coating has a great affinity for the metal shell, instread of attaching to the metal surface by physical combination, penetrates into the metal shell through chemical reaction with metal. It can change the metal permeable zone structure with Si-Al crystal phase and achieve heat insulation and wear resistance effect.
     Even more amazing, after using this coating, the linear change and expansion coefficient of the metal permeable zone will be changed, the metal will get closer to the high temperature characteristic of refractory, has stronger affinity for the attached castables, avoiding refractory cracking or falling off.
