Randy machine glass tempering furnace glass furnace steel _ [price] _ glass tempering furnace is 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 installation and replacement encoder, soft axis and its rotation axis to both ends at the same level, and better concentricity rotation; shaft at both ends of the connection must be tightened and checked regularly, it will affect the normal use of the encoder loose connections; encoder and its bracket must To fixed firmly, not cause encoder and stand shaking and shaking when the motor is rotated, otherwise it will affect the normal use of the encoder; wiring of the encoder must use shielded cable, shielded cable to connect to and PE, can not and equipment enclosures casual connection, the other end of the shield should be connected to the low voltage ground pile cabinet. Glass deformed mainly from two aspects, the 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.
