Overall Seamless Casting Technology of FurnaceHeart

It is a newtechnology of re-building ceramic cup, which is characterized by setting upmold and casting cling to carbon brick. The casting ceramic cup and carbonbricks will be seamless connectivity, which makes the structure of furnaceheart compactly and tightly. And there is no filling layer between traditionalceramic cup and carbon bricks, which cut down thermal resistance layer,guarantee the overall heat conducting efficiency, protect the safety of furnaceliner and avoid the occurrence of potential risk.
