Adjustment of the coke oven exhaust rod
Thread Content
The pull rods for coke oven exhaust gases tend to break easily, and the heights of these pull rods differ after two direction changes. I would appreciate some advice from those with more experience!
The adjustment of the coke oven exhaust pull rod is one of the key factors in ensuring a reasonable and stable level of coke oven exhaust emissions. To address the issues of easy breakage of the tie rods and inconsistent heights of the reversing tie rods, the following points should be considered: 1. Material selection: Choose materials with high strength, wear resistance, and corrosion resistance to manufacture the tie rods, in order to extend their service life. 2. Regular inspection and maintenance: Regularly check the wear of the exhaust rod in the coke oven, and replace or repair it promptly if any issues are found. At the same time, lubricate and maintain the tie rods to ensure their smooth movement. 3. Set the height of the tie rod reasonably: During the operation of the coke oven, adjust the height of the tie rod according to actual needs to ensure stable exhaust gas emissions. During the commutation process, the position of the tie rod should be adjusted to meet the requirements of coke oven operation. 4. Install protective measures: Add some protective devices to the pull rod, such as measures to prevent it from being too long or the installation of protective covers, in order to reduce damage to the pull rod caused by external factors. 5. Monitoring system optimization: By integrating modern monitoring systems, automated control is implemented for the exhaust rod of the coke oven, thereby reducing the impact of manual operations on the rod and enhancing stability. In summary, the adjustment of the pull rods for coke oven exhaust gases requires comprehensive consideration of factors such as material quality, regular maintenance, proper height setting, installation of protective measures, and optimization of the monitoring system, in order to ensure their proper operation and enhance stability. .
It must be a round steel tie rod, not a flat steel tie rod. The actual stroke of the exchange system exceeds its theoretical stroke; only when there is a stroke margin do variations in height occur. In my opinion, the fundamental reason for broken exchange rods or uneven heights is excessive stroke resistance. The high resistance during the gas stroke or during the discharge of exhaust gases is the root cause.
It breaks easily due to obstruction; the high resistance causes it to break at the weld site. Additionally, the quality of the weld is poor, so it is necessary to reinforce the weld area by adding welding reinforcement bars.
