Static (dynamic) slag breaking frame bridge problem
Thread Content
It is said that the formation of a bridge corresponds to an increase in the length of the downcomer, which increases the disturbance of the water at the bottom of the quench chamber and raises its temperature, thereby causing an increase in the temperature of the lock hopper or exceeding its optimal temperature. Not quite in agreement with the idea that it’s equivalent to increasing the length of the downcomer? Please let fellow sailors discuss
Bridge construction should not involve increasing the length of the downcomer; expert guidance is needed to resolve this issue.
Could you mention the views you disagree with?
The slag breaking frame bridge does not have the side effect of increasing the length of the downcomer; it does affect the slag in the quenching chamber, allowing it to enter the slag breaker and be crushed. It raises the temperature at the upper part of the lock hopper, but lowers the temperature at the lower part.
What causes the temperature at the upper part of the lock barrel to rise while the temperature at the bottom decreases?
The slag bridging can be detected from the circulation flow rate of the hopper circulation pump, and bridging does not cause an increase in temperature at the upper part of the hopper.
It is easy to understand that a decrease in the circulation rate tends to support conditions that do not cause an increase in the temperature at the upper part of the lock hopper
Are there any users who agree that it serves to extend the downcomer? Exchange with each other
If it affects the circulating water flow, then it’s likely not just a bridge formation there but the passage is almost completely blocked
That’s right! But this is not the place to discuss that
