Tempering Furnace | Landglass steel furnaces | Continuous Steel forced convection furnace is provided by Randy machines. Randy Luoyang Glass Machinery Co., Ltd. (www.landglass.com) located in Luoyang City, Henan Luoyang City Road on the 12th king, Contact: Mr. Qin 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. 1.3 Cooling thermal deformation caused by uneven known that glass is heated to the softening point after being cooled rapidly at the surface of the glass to generate sufficient compressive stress, tensile stress and compressive stress equilibrium process is tempered glass in the interior of the glass, glass and steel when subjected to an external force after the first release of stress, and then produce tensile stress in the glass surface so that the strength of the glass is higher than that of ordinary glass. Tempered glass is glass in the permanent stress, will produce stress in the glass when unbalanced deformation: When compressive stress on the surface is greater than the lower surface tensile stress, in order to balance the stress in the glass is bent downward, and similarly, the current surface compressive stress bending compressive stress than the surface stress in the glass up to the balance, the glass in the cooling process due to both the upper and lower surfaces of the cooling rate is uneven, the cooling speed of the surface stress is greater than the slow cooling surface.
