Glass Tempering Furnace, Randy machine glass tempering furnace, glass furnace steel suppliers to display "# Randy Luoyang Glass Machinery Co., Ltd. (www.landglass.com) 2014 has been newly upgraded launched when OP? ### PLC ERROR ", and displayed in the display box value" ##### "instead of the value, this kind of failure is often between the PLC and OP communication caused by the no. 1. Check the adapter and its connection interface (dual OP inspection DP connector); adapter side has two lights are flashing when normal; 2, check the PLC's power supply is normal: Look 24V DC on the cabinet is normal, Please handle the power module failure is not normal according to the circuit diagram. Common reasons are: 1) AC220V power supply is not normal; 2) DC24V line is grounded. 3, check whether the PLC red and yellow light, if there is, please contact with Randy. 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.
