Analysis of the harm and treatment measures of broken glass residue in the tempering furnace

I. broken glass cannot be left in the tempering furnace

in any case, broken glass cannot be left in the tempering furnace. The furnace should be shut down to cool down and clean up copper materials with more than 1billion yuan in Tongling Economic and Technological Development Zone, and more than 20 broken glass industrial enterprises in the blank field of China's material manufacturing industry should be made up. Because the broken glass will melt when it is left at the bottom of the heating furnace, and it will affect the heat dissipation at the bottom of the furnace when it is deposited on the bottom radiation plate. If the broken glass contacts the furnace wire, it will cause the furnace wire to be grounded or burned out

II. Treatment method of glass sticking to the ceramic roller table

in the process of toughening glass, if the furnace door is not opened in time and heated, when the button on the screw is located in the keyway of the pendulum for a long time, the transmission stops and other equipment failures, the phenomenon of glass sticking to the ceramic roller table may occur. The correct treatment method of this phenomenon is as follows:

1. Stop the equipment, cut off the heating power, open the heat dissipation valve, and raise the front and rear furnace doors, Cool down

2. If the glass sticks to the ceramic roller table in a large area, the main rotation should be stopped to cool naturally. If only a few amplifier units are stuck, is it normal? 1. The ceramic roller table that must be checked can be removed from the drive belt of these roller tables, stop the rotation of these roller tables, and maintain the operation of other roller tables

3. After the furnace body is reduced to room temperature, raise the furnace top and insert the safety pin

4. For single-layer large-area glass adhered to the ceramic roller table, gently pick it with a wooden stick, and the glass can be automatically disengaged and cleared out of the furnace

5. Lift out the roller table, and clean the multi-layer glass adhered to the ceramic roller table with a wooden stick bit by bit until the broken glass is completely stripped from the roller table

6. Grind the roller table with 300 #~600 # water sandpaper until it is smooth and free of foreign matters

7. Do not operate the roller table if it is not completely cool, otherwise the surface of the roller table is easy to stick off and form pits, which will damage the surface quality of the roller table
