Summer solstice, the country generally enters the hot season, high temperature, sufficient light at the same time. The production site temperature of special industries such as metal smelting is higher, so how to do a good job of high temperature and high heat protection has become the most important. Before the high temperature converter, the flying steel flowers are like a tornado spraying fierce fire from time to time. Under the conditions of high temperature and high heat, the cables and hoses near the high temperature areas such as converter and continuous casting are aging rapidly and need to be replaced frequently to ensure the normal operation of the equipment. Beijing Great Pack Brand heat-resistant and heat-insulating fire proof sleeve perfectly solves this problem and ensures the smooth operation of iron and steel smelting and other safety production. At the same time, a variety of practical materials, high-temperature sleeve, high-temperature blanket, anti-thermal radiation materials and other products are introduced, which can effectively prevent heat radiation and heat transfer, corrosion resistance, high-temperature physical and chemical stability, simple, economical and practical. They are the remarkable characteristics of Beijing Great Pack high-temperature fire-resistant materials. It is not easy to think about material resources and feel the difficulties of crops. Beijing Great Pack will spare no effort to provide more high temperature and heat protection solutions for iron and steel smelting and other industries.
