Forced convection flat tempering furnace, steel furnace, steel furnace Landglass provided by Randy machines. We are Luoyang Randy Glass Machinery Co., Ltd. (www.landglass.com) in: Luoyang specializes in: steel furnace, glass tempering furnace, forced convection tempering furnace, convection oven, dual-chamber furnace glass deformation mainly from two aspects First issue is the precision roller, the second is the problem of uneven stress. 1.2 due to the heating caused by the thermal deformation temperature unevenness exists 1.2.1 glass surface temperature difference during the heating up and down, when the glass is delivered to the heated rollers, the lower surface of the glass in contact with the roller, the heating roller directly conducting manner glass by heat exchange, on the surface of the glass on the surface of the glass is heated by way of heat radiation, the heat transfer rate is higher than the upper surface of the lower surface of the heat transfer rate, when the thermal equilibrium is not taken when the auxiliary heating, the surface temperature of the glass lower than the temperature of the lower surface, and at the start of heating the glass is a typical elastomer, the thermal expansion coefficient and relatively high glass (linear expansion coefficient of the glass was 9 × 10 / .C), since the surface temperature is higher than the temperature of the upper surface , the expansion rate is higher than the upper surface of the lower surface of the glass that is bent upward from the glass surrounding Alice roller to form an intermediate glass is heated, and is only the middle roller support, when the glass is further heated in contact with the roller position First to reach the softening temperature and subjected to the full weight of the glass, the middle of the glass will occur "floating" deformed, resulting in thinning of the site and asked the roller prints and even optical distortion. On the other hand when all the glass is heated to the softening temperature of the glass flattened, but the temperature difference did not disappear with the temperature difference between the glass is uniformly cooled to room temperature, the contraction is greater than the cold surface of the glass heat shrinkage to form the heat curved surface. After the recognition, a warm and cheerful dance song "dance Tage" opened the curtain of the variety show, colorful program dizzying. The party wrote and performed all the employees, a clear theme, content rich, diverse, and many creative programs are derived from the employee's daily work and life, so live performances abnormal warm atmosphere, applause and cheers come and go, a wave high wave, which Pieces "new mom and Yangbailao", "News Network", "one thousand sad reasons" and other classic songs medley, men and women comic dialogue "open sesame" dance "Nobody", "injury can not afford adaptation Edition, "" New Love Song of Kangding>, the song "Thank you for your love," "my good man," "New Drunken Beauty", etc., set off waves of performances climax, enjoy showing people Randy versatile, affectionate to eulogize a man sailing Randy lofty aspiration, vigorously carry forward the spirit of innovation Randy people, art reproduction of a new climate Randy cultural construction; theme poetry recitation "sail 2012" is a poetic language depicting more Randy better tomorrow, resonates powerfully of all employees; in the chorus "love each other family" sensational singing, the annual awards ceremony Landglass cum New Year party draw a satisfactory conclusion.
