1. Insulation condition; The heat generated only needs to compensate for the heat used by the furnace body due to heat dissiption. The heat dissipation string is set and the change process is slow. The PID adjustment method is used to control, the effect is ideal, and the fumace can be heated easily. The temperature is kept in the range of plus or minus 1

2.Heating conditions: When the glass only enters the body of glass tempering furnace, the original heatequilibrium state suddenly breaks, causing a sharp drop in furnace temperature, which is between 20-100. When the glass temperature increases, the fumace temperature graduallytends to the set value, untill the glass temperature is consistent with the fumace temperature the heating process is also declared over.]]> 2022-04-28 04:53:06 UTC https://padlet.com/nurshuhadaarbaan/er2qnfkoc5ws5b61/wish/2161555817 https://padlet.com/nurshuhadaarbaan/er2qnfkoc5ws5b61/wish/2161555991 1.
