Steel furnace, Landglass steel furnace, gas heating glass tempering furnace is provided by Randy machines. Steel furnace, Landglass steel furnace, gas heating glass tempering furnace is Randy Luoyang Glass Machinery Co., Ltd. (www.landglass.com) 2014 has been newly upgraded launched to clean up the most as a preventive maintenance measure roller roller ideal. Periodic cleaning depends on glass quality requirements, glass thickness and the amount of SO2. Usually 4 weeks to eight weeks or six months range. Do often require heavy construction glass furnace maintenance, roller cleaning and excessive application of SO2, in steel furnaces and when the normal use of production. Ceramic rollers can be cleaned with water, demineralized water priority. Absolutely no detergent. Detergents may react chemically with the roller, resulting in crystallization and scrap roller. Because of its very low thermal expansion coefficient of the material, so the roller can be washed in hot conditions. Glass chips roller surface can be due to the cold water hit the hot thermal shock resistance after peeling off roller. Throughout the cleaning process, it should pay attention to protect the shaft head to prevent overheating. Roller at the room temperature can be well cleaned. Soft linen towel as 3M's Scotch Brite very effective. After clean-up roller to be dried. If the roller is flooding over, and is heated too quickly, the roller surface will form a vapor leaving the roller damage. In the roller surface sediments generally sodium sulfate, may also contain other elements from the glass or from the dust and debris of glass, lined furnace or other sources of material. The key to solving the problem of asymmetric glass temperature below is to enable the furnace nozzle system, sprayed into the air, causing the forced convection 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 temperature in the furnace 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.
