Tempering Furnace | LD-D bending steel furnace | Landglass steel furnace provided by Randy machines. Steel furnace, Landglass steel furnace, gas heating glass tempering furnace temperature is the key to following the issue of asymmetric Randy Luoyang Glass Machinery Co., Ltd. (www.landglass.com) 2014 has been newly upgraded glass is introduced solve Enable furnace nozzle system, is injected into the air resulting in forced convection of heat in the furnace, it will form a forced convection heating, compensate for thermal conduction, so that the furnace temperature distribution is more uniform, thereby improving the coated glass and Low-E glass in the oven The temperature in the heating process is not balanced, improve steel quality coated glass. In actual production, in order to avoid burning the film, the temperature setting on the whole lower than ordinary transparent plate glass steel 5 ~ 10 ℃, but the upper temperature setting 10 ~ 20 ℃ higher than the lower, the heating time longer than ordinary clear sheet glass 50% to 80%. Then by adjusting the nozzle into the air pressure to adjust the degree of forced convection, maximize improved temperature uniformity in the furnace during the heating of the glass, before producing a good quality coated glass. 2.3 Measures for controlling thermal deformation due to uneven cooling caused by the stress generated in the cooling process is uneven, the cooling rate can be adjusted by adjusting the glass surface air pressure gate. If the glass is bent downward, which can be adjusted by increasing the pressure at the bottom of the grille to improve cooling rate of the surface under glass; if the glass bending upward, through the upper portion of the gate to increase the wind pressure on the glass surface to increase the cooling rate regulation.
