1. The upper plate table of the glass toughening furnace must be cleaned once a shift to prevent dust from entering the toughening furnace and causing contamination of the ceramic roller table (small pitting);

2. When the glass "blast furnace" is found, the ceramic roller must be cooled down and cleaned in time. Do not use glass to wash the ceramic roller.

3. the choice and use of heating temperature should be appropriate, the heating temperature should not be too high, not to improve the yield of products and take high temperature for a long time to heat, the glass surface of the ceramic roller table will form a dense potting, glass surface of the white point is from the surface of the ceramic roller;

4. Once pitting is found on the glass surface (except for reasons such as unclean air grid roller table, excessively high furnace temperature and excessively long time), timely clean the ceramic roller table;

5. When there are protrusions on the surface of the ceramic roller table, the water sand paper over 400 mesh can be used for grinding. After grinding, carbon tetrachloride can be used for cleaning to avoid the powder from being attached to the surface of the ceramic roller table. The white cloth stained with carbon tetrachloride should be made of pure cotton and soft material that does not shed wool. Care must be taken when wiping the ceramic roller table.

6. if the use of distilled water or purified water to clean the toughened furnace ceramic roller table, it must be noted: the water on the surface of the ceramic roller table will not evaporate quickly, it is strictly prohibited to rapidly heat up the surface of the ceramic roller table with water, should avoid the adverse impact on the ceramic roller table.
