Glass defects in the process of glass mirror and the solutio

  Tempered glass mirror will encounter the process of bending down the glass, resulting in the problem and the reasons for the solution:

  1.When observing the sight glass away from the steel furnace, the glass surface temperature on the top of the mirror is below the bottom temperature; the solution is to reduce the temperature at the bottom of the furnace.
  2.The hardened surface of the cooling surface has a hardening strength higher than that of the bottom surface; the solution is to increase the hardening pressure of the cooling air at the bottom.
  3.The upper air door is too low, the head pressure is too large; the reverse damper, reducing the top of the glass blowing pressure.
 
  If the toughened glass mirrors downward, that is, the glass mirrors are placed horizontally, the middle part of the glass sight glass is convex.
