Fire goggles are made of blue cobalt glass. They have very good fire protection functions. They are suitable for power plant boilers, cement plant rotary kilns, glass melting kilns and so on. They are also special steel-making goggles for steel mills.
Blue cobalt glass is a kind of traditional fire glasses. Its superior function of filtering and protecting eyes makes it widely used in power plants, steel plants, cement plants, glass factories and other high temperature sintering furnaces. It can filter out ultraviolet radiation, infrared radiation and strong visible light, and effectively protect the eyes of the observer. In power plants, when we burn a boiler, we often need to observe the furnace of the boiler. At this time, we need to wear the blue goggles we have prepared for you. With them, we can clearly see the flame burning in the furnace without being damaged by ultraviolet, infrared and strong visible light.
