Blast Furnace Burden: Fix Slips, Bridges & Channeling

Ajouté : 2026-05-16

[00:00:00]Burden descent by gravity alone. Three things fight against it. Wall friction, internal friction, and upward gas pressure. Remember, moving burden has only 40 to 45% of its static weight. So, movement actually helps to prevent the scaffolding on the wall to keep the burden moving as smoothly. Coming to the uh watch for the blast furnace volume rising, pressure dropping, and top temperature spiking in one direction. To fix it, reduce blast briefly, then adjust burden distribution. Ignore channeling lead to slip and bridges to act fast.

[00:00:36]Burden drops suddenly over a half a meter breeze. Burden stops moving for over a minute. So, prevention good coke quality, match blast permeability, and keep the hearth active. If breeze happens, ensure enough heat, add blast gradually, and don't charge too fast after a sleep. So, stop sleep, stop breeze.
