Landglass steel furnace, [single] face bending steel furnace, steel furnace provided by Randy machines. Randy Luoyang Glass Machinery Co., Ltd. (www.landglass.com) located in Luoyang City, Henan Luoyang City Road on the 12th king, Contact: Mr. Qin five, coated and tempered coated glass Low-E glass, especially Low-E glass The steel production, is the largest problem, difficult to master the technical parameters of a glass in the presence of steel production. When the coated glass and Low-E glass tempering glass up and down the biggest difficulty is not the same on both sides of the heat absorption rate. Glass surface has a high emissivity (approximately 0.9), the surface temperature rises too fast, but low emissivity coated surface (as low as 0.1 to 0.23), the heating process a large amount of the reflected radiation, by thermal radiation is not easy transmitted to the inner surface of the glass. This asymmetric heat absorption rate, resulting in an asymmetric upper and lower surfaces of the glass sheet temperature, causes bending glass, from a variety of defects fog, falling film, optical distortion, arcuate and the like. 1.2.3 random uneven temperature distribution over two uneven temperature distribution is mainly caused due to improper operation, random uneven temperature distribution may be caused due to poor equipment condition, heating wire steel furnace has damaged local temperature sensor The position changed or distorted, glass in the laying rollers unreasonable, are cause uneven heating glass, this random uneven temperature distribution, will lead to the glass plane direction uneven temperature distribution in the heating, glass in the cooling contraction, different regions occur irregularly and do not shrink law will result in poor glass flatness.
