Normally, artillery piece of hydraulic pressure mud and opportunity of hydraulic pressure mouth are provided in the meeting before blast furnace, iron mouth and the operation that open iron mouth are blocked up when using taphole of the smelt that finish respectively. After finishing the mouth that block iron up to work, can appear sometimes the hand of system of circumgyrate of artillery piece of hydraulic pressure mud moves reversal valve malfunction, hydraulic pressure mud prepares Chinese medicine by roasting it in a pan cannot seasonable go back, bring about burn prepare Chinese medicine by roasting it in a panbig gun, then blast furnace rests the accident of wind, need changes artillery piece of hydraulic pressure mud and maintenance of 5h left and right sides will resume blast furnace production.

The analysis thinks, the whirl that can prepare Chinese medicine by roasting it in a pan hydraulic pressure mud of loop and mouth machine auger cut installation connects loop aside between loop,

Fine melt into: On machinery, in hydraulic pressure mud prepare Chinese medicine by roasting it in a panbig gun rotates the antrum having lever of loop and mouth machine get those who cut motor 3mm of φ 16mm × is using between oil path coming back without seam a canal to undertake a butt joint, the antrum do not have lever that loop rotates artillery piece of hydraulic pressure mud in the meantime and mouth machine get those who cut motor to go against what 3mm of φ 16mm × also uses between oil path coming back to not have seam a canal to undertake a butt joint, argon arc solder is used when soldering. Leave in what the high-pressured shut-off valve that 16mm of a φ installs respectively among two pipeline will control oil path, shut. When blast furnace is normal, these two shut-off valve are closed.

When the hand stirs reversal valve occurrence trouble, shut mouth engine quickly get two shut-off valve that cut return, open two bypass shut-off valve, lubricating oil pump of the mouth that start, achieve return of artillery piece of hydraulic pressure mud. Should change after ace moves reversal valve, close bypass shut-off valve, open mouth opportunity auger cut oil path shut-off valve, use hydraulic pressure mud to prepare Chinese medicine by roasting it in a pan the system undertakes the mouth works blocking iron up afresh.

Above transforms an operation to install steel ironworks in home get applied on blast furnace of two 2000 class, look from the feedback of professional, after transforming, the accident of burned-out barrel is not recurrent, and the amount of labor that maintains labour and jockey is reduced greatly, the effect is very good.
