LDAL continuous flat tempering furnace, steel furnace Figure Landglass, LDE hyperboloid bending steel furnace

Landglass selected OMRON photoelectric switch is the company's products, the model is E3S-5DE4; the products are divided into two parts, transmitting and receiving, respectively, ↑ (emission) and ↓ (receive) flag. There are green (STABILITY) and red (LIGHT) and a sensitivity adjustment knob on top of the receiving part. Photoelectric switch adjustment method is as follows: 1, with a 50 × 400mm size of 4mm glass on the rollers, adjust the height of the photoelectric switch, the glass just in photoelectric switch (receive and transmit the same) in an intermediate position; 2, adjust the photoelectric switch the receiving end and the transmitting end, it ends just opposite, not about dislocation, and at the same level; 3, adjust the receiver sensitivity knobs to have the green light when the glass between photoelectric switches, red light off; when no glass green light and the red light at the same time; 4, glass photoelectric switch positions by the release of the adjustment, and the glass in any position between the photoelectric switches, photoelectric switches are in line with the reaction described in 3; 5, to meet the above conditions are normal when the transmitter red light on or off are considered normal. Fifth, coating and steel coated glass Low-E glass, especially steel production Low-E glass is the most problems, the most difficult to master the technical parameters of the presence of a glass and steel production. When the coated glass and Low-E glass tempering glass up and down the biggest difficulty is not the same on both sides of the heat absorption rate. Glass surface has a high emissivity (approximately 0.9), the surface temperature rises too fast, but low emissivity coated surface (as low as 0.1 to 0.23), the heating process a large amount of the reflected radiation, by thermal radiation is not easy transmitted to the inner surface of the glass. This asymmetric heat absorption rate, resulting in an asymmetric upper and lower surfaces of the glass sheet temperature, causes bending glass, from a variety of defects fog, falling film, optical distortion, arcuate and the like.
