The first part Liquid Material Quality-1.pdf
Glass with stones or bubbles (concentrated in the pick-up pool)
|There are many small round bubbles in the product, blanket thickness||The temperature in the furnace is too low||If the furnace temperature is too low will lead to liquid material clarification is not good, no melt good material once it reaches the flow hole, clarification is too late||Increase the temperature in the furnace. Accelerate the liquid melt process, reduce the amount of material at the same time improve power.|
|Small stones or round bubbles||The actual production capacity of more than the furnace design tonnage||The batch / feedstock is not fully clarified||The output must be below the maximum designed tonnage|
|Small stones or round bubbles||Clarifying agent with the material is not sufficient||A small amount of clarifying agent is not conducive to the gas discharge glass liquid.||Increase the content of clarifier|
|Small stones and larger round bubbles||Clarifier content is too high||High content of clarifier will produce a lot of bubbles, too high sulfate content will produce bubbles||Reduce the content of clarifier, until the feed liquid turn well to determine the proportion of clarifier in the feed side|
|Small stones or large round bubbles||Electrode cooling water jacket leakage||Water vapor causes stones or bubbles||Turn off the cooling water or replace the electrode cooling water jacket|
There are stones in only one course
|There are crag stone fragments in the course||The product supplied by this channel contains air bubbles. Cristobal element has been broken down||Rinse the material to remove impurities|
|There are metal fragments inside or near the chute||Big bubble||Remove metal debris|
|Big long bubble||Involved in the air||Blender rotation or air entrained by the feeder||Adjust the rotation speed of the stirrer so that it can be continuously changed|
|Stones / long bubbles||Electrolysis||All the inside of the material is occurring||Disconnect the ground electrode or T / C|
|Glass with stones or bubbles (concentrated in the pick-up pool)||Large bubbles with metallic luster ||Electrolysis||A galvanic cell is formed between the electrodes due to the potential difference||Under the guidance of technicians DC plating suspicious electrodes|
