Thermal Wet Spraying Lining Technology for Blast Furnace Lining
Blast furnace is the main equipment for continuous high-temperature operation of ironmaking, its lining due to long-term impact, erosion, melting loss and local or large area of shedding, resulting in a large change in the operating furnace type of the blast furnace, and then the furnace condition appears repeatedly abnormal. Extending the service life of blast furnace lining is a subject that smelting engineering and technical personnel have been concerned about. At present, the dry spraying lining technology has been used at home and abroad, which has the characteristics of convenient construction, less time-consuming and fast production compared with the traditional shutdown bricklaying maintenance. However, due to the uneven mixing of water materials (adding water at the muzzle), dry spraying has the following disadvantages: high rebound rate, loose spraying layer structure, short service life, serious environmental pollution and so on. Hebi Zhongsheng Metallurgical Engineering Co., Ltd. combined with the actual after long-term research and development, the use of wet conveying and remote spraying combined with wet spraying technology, a good solution to the above problems, has been generally welcomed by users.
