The service life of the ceramic roller table of the tempering furnace is closely related to the use method, maintenance method and application environment of the equipment.

　　Ceramic roller table cleaning steps:

　　1. Clean your hands before touching the ceramic roller table of the tempering furnace. If your hands are oily or dusty, they will contaminate the roller table and increase the difficulty of cleaning. (It is recommended to wear disposable latex gloves to better protect your hands and rollers. Road) Use a fiber towel (car wash towel, no lint) and pure water to wipe the ceramic roller table first to clean the dust on the roller table.

　　2. If there is any attachment on the roller table that can't be wiped off, touch it with your hand to feel whether there is a feeling of unevenness. If it is a raised substance, wipe it back and forth with a scouring pad (dishwashing cloth) and pure water with proper pressure. Note ⚠️: During cleaning, it is forbidden to dry wipe and sand without water. You need to spray water while sanding.) Because the scouring pad is softer than sandpaper, it will not scratch the ceramic roller and has a good effect of removing foreign objects. After cleaning, touch it with your hand again. If there is a bulge on the roller table, you can use sandpaper to polish it at this time. The sandpaper is made of diamond (Diamond Mohs hardness: 10, Fused silica Mohs hardness: 7), which will abrade the surface of the roller table. It is recommended to use 800-2000 grit sandpaper for sanding. The sanding method is still wet sanding and spraying water while sanding. The water not only plays a role of lubrication and protection, but the sanded particles will be taken away with the water. If the attachment is granular, you can directly use 2000 grit sandpaper. If the attachment is large, use 800 grit sandpaper to clean it and then use 2000 grit sandpaper to lightly polish and repair the surface scratches. When using sandpaper, you can use a sandpaper pad to pad on the back of the sandpaper. The sponge on the pad has a buffering effect, cleaning and reducing the scratches on the roller surface.

　　3. If there are stains on the surface of the roller table that cannot be wiped off and touched with your hands without unevenness, you can use a dry eraser. If the eraser can reduce the stain but is not thorough enough, you can wipe the stain with the eraser soaked in alcohol liquid, and clean it with pure water after wiping. Before installing the ceramic roller table into the furnace, make sure that the roller table is dry. If it is wet, you can use a hair dryer to dry it. Note: The ceramic roller table must be cleaned and polished outside the tempering furnace. It cannot be cleaned and polished in the tempering furnace. If the grinding dust in the furnace falls into the furnace, the air circulation will bring the dust to the roller table after the temperature rises, which can only be a large amount. The glass drag furnace can reduce the dust in the furnace, increase the cost and affect the output!

　　The maintenance of the tempering furnace includes heating elements, insulators, insulation layers, thermocouples, element protection covers, etc. The cleaning of the glass heating section furnace is very important, especially the tempering furnace equipped with refractory fiber lining, because the dust of the fiber lining will fall on the surface of the roller table (fused silica has a certain viscosity and electrostatic adsorption at high temperatures). Marks appear on the lower surface of the glass. If the insulation material is damaged, use a vacuum cleaner to remove the loose dust from the damaged location, and repaint the insulation material with silica sol to harden the surface of the insulation material. Use a vacuum cleaner to thoroughly remove the dust in the furnace, including the dust hidden under the thermocouple of the lower furnace body. If the dust is not completely removed, the air will flow in the furnace after the temperature rises, and the dust will be blown away and re-accumulate on the roller table and the glass.

　　A rough surface of the roller table will affect the contact surface between the glass and the roller table, and may also cause defects. Damage to the steel sleeve or loose sleeve is also an important factor affecting the normal operation of the roller table. In order to avoid this possibility, it is necessary to ensure that the furnace cannot be opened at a high temperature to expose the roller steel sleeve to the high temperature.

　　The service life of the ceramic roller table of the tempering furnace depends on the daily cleaning and maintenance of the equipment to a large extent. Therefore, everyone must pay attention to the daily maintenance of the equipment during use.
