In the cold repair of the 650t/d float furnace of China Glass Blue Star, a new technology of self-closed mold support was adopted, and the large self-closed construction of the melting part was completed.

In order to reduce the owner's cold repair cost to the greatest extent, the construction technology innovation of the engineering and technical personnel of our company's China Glass Bluestar (Linyi) Project Department adopted the self-closed structure without downward rotation and supported by reusable steel pipes. When making the self-chin, calculate the position of each supporting point to be accurate. When constructing steel pipe support, calculate the height of each support point of the chin in advance, ensure that each support point is in place and strictly confirm the force of the support point. Thanks to the efforts of the on-site engineers and technicians of the project department of our company, the safe and high-quality construction of the large crown of the melting department was successfully completed. Self-closed mold structure without downward rotating steel pipe support, 650t/d float furnace, large self-closed melting part with a self-closed span of 12800mm, saving 150m3 of wood and 6,000 yuan of construction auxiliary materials. Really realize "creating value for customers".
