How to adjust the exchange gas and exhaust gas stroke? answer: (1) Adjust the large stroke according to seasonal temperature changes. Use a tensioner to adjust the stroke according to temperature changes and the lifting height of the thallium rod of the whole furnace so that the difference from the specified standard does not exceed ±5mm. (2) Regularly comprehensively inspect the gas system and exhaust gas system equipment, including the four-corner pulleys, and lubricate them. (3) Check the tightness of the exchange braces and chains of the gas system and exhaust gas system every day for cracks, the lubrication and cleanliness of each part, and whether there is any wear or jamming during the exchange, and solve any problems in a timely manner. (4) When the lifting height of individual thallium rods exceeds the specified range, the small thallium rod chain can be adjusted, the washer of the clamp sleeve can be added or subtracted, or the small stroke can be adjusted. After adjustment, it is ensured that each thallium rod is dropped tightly, and the lifting height of the exhaust gas does not exceed ±5mm, and the gas gas does not exceed ±1mm. (5) Check the exchange of cocks every day. Check whether the switch position is correct and the deviation does not exceed ±3mm. Check whether the lever is flexible and whether it is over-tightened, jammed, or fallen off. 6. How to deal with the waste gas from the gas exhaust panel? answer: The following measures should be taken to treat and remove thallium from the exhaust gas from the gas exhaust panel.: (1) Turn off the gas control during downdraft.
