Precautions for safe use of ceramic roller table of glass toughening furnace

As the key component of the toughening furnace, the quality of the product and the quality of the installation directly affect the quality of the toughened glass. According to the on-site experience, in view of the matters needing attention in the transportation, installation, maintenance and production process of the ceramic roller table of the glass toughening furnace, the following points are summarized for the reference of relevant personnel:

In the process of installing ceramic roller table, it is necessary to handle and put it gently, especially when it is temporarily placed on the ground support, it must be fixed to prevent the roller from rolling to the ground and causing damage.

Ceramic roller is installed into the furnace, the roll must be put in furnace heat preservation material on both sides round hole in the middle of the, if not in a central location for heat preservation material processing, appropriate furnace press on at the same time to ensure that the appropriate position, on preventing furnace excessive press, the heat preservation material round hole extrusion deformation, cause the roller card lag rotation is not flexible, wobbles, until the roll fracture.

In the process of installation, appropriate protective measures should be taken to prevent roller damage and affect product quality.

For the maintenance of ceramic roller, the following points should be emphasized:

Strict inspection of the upper plate, it is strictly prohibited not to clean, grinding edge of the original piece and glass into the furnace with edge defects, but also to prevent toughened glass into the furnace for the second time, to prevent the explosion of glass in the furnace caused by scratches on the rollers and other damage.

Emphasis on users and make the system: the temperature over 300 ℃ above, the equipment must be have staff on duty, regularly check the main drive and each roll is stalling, found that the problem should be dealt with in a timely manner.

For users who have first contact with the toughening process, it should be emphasized that one person should operate and set the process parameters and the other person should confirm and check to prevent the phenomenon of thin glass sticking to the furnace and thick glass blasting furnace caused by improper setting of the process parameters.

It is emphasized that the back door can not be opened due to air compressor problems and other faults should be quickly climbed to the top of the furnace, with the manpower to open the back door of the furnace, so that the glass quickly discharged, prevent sticking to the furnace.

In order to avoid unnecessary loss caused by wrong rolling direction, it is necessary to carry out field exercises on the treatment methods for possible sticking and blasting furnace faults, so as to be able to operate skillfully in emergency treatment. It is necessary to pay attention to the reliability of the hand mechanism and the shaking direction of the hand mechanism.

Should emphasize especially, once occurrence blackout, operator must not panic, should be under the unified command of the monitor, open the back door of the furnace, shake furnace main drive (had better be before and after end shakes together). At the same time, make the wind grid shake synchronously to prevent the glass from remaining in the furnace and causing adhesion to the furnace, or the glass accumulation in the furnace door can not come out, causing adhesion to roll or roll scratches.

If sticky roll glass cannot be shaken out of the oven, wood rods can be used to lift up. It is strictly prohibited to use metal rods to row or knock on ceramic rollers. Stick roll glass is not allowed to carry hard carry, wait for the temperature-natural cooling to room temperature of the temperature-steel furnace, tapping with rubber bar, glass and ceramic rollers will naturally peel off.
