Hole can reveal liquid slag）.Lower outside, which is provided with, turns over tank hanging scroll.In order to reduce the idle space between autoclave pressure and slag ladle
（Reduce steam pressure loss）, slag ladle do not set hanging axis.When lifting, the upper edge of slag ladle is caught on using extraordinary electric lifting tool.
Cooling tube can have at least two modes：The heat resisting pipe A of reuse and disposable prefabricated slag pipe B.
A:Cooling tube is made of heat resisting pipe, fixed plate and lifting lug.More steel pipes are arranged in parallel.Steel pipe lower end is sealing
Tip, side-wall hole（10 ~ 15mm of diameter）.Steel pipe upper end opening.It is welded by steel plate between pipe, is fixed into an entirety.Lifting lug
It is welded on the center on top.Steel pipe material is preferably 310S or higher level, 76 ~ 159mm of diameter, depth of the length more than slag.
300 ~ 600mm of tube spacing.Since the heat conduction of slag is poor, heavy wall cooling tube can keep certain intensity within a certain period of time.It is cold
But pipe is inserted into liquid slag and does not exceed 5 minutes to the time between shower water.After slag cools down, due to the coefficient of expansion ratio of steel pipe
Slag is order of magnitude greater, and gap is will appear between steel pipe and slag, and cooling tube can be extracted out integrally.Cooling tube can also use solid
Reticular structure is placed in slag ladle in advance, then, liquid slag is added by funnel.The every cooling tube placed in advance makes folder
Layer structure, makes internal layer have certain intensity.Even interlayer（Heat-barrier material can be set between interlayer）Cooling tube is being added
Liquid slag did not exceeded 20 minutes to the time between shower water.
B:Disposably cooling tube is added concrete prefabricated using steel slag, can not be limited by heating time, even if there is breakage
Do not influence using effect.Before use, being first slowly preheating to 650 DEG C, heat preservation 15-40 minutes prevents wherein prefabricated cooling tube
The crystallization water explode.Prefabricated cooling tube intensity need not be too high, to reduce the broken difficulty in later stage.Prefabricated cooling tube
Endoporus can be small（More than 10mm）, appearance can be at tooth form, and increase film-cooled heat, wall thickness is not less than 40mm.The effect of cooling tube
It is the cooling velocity for making slag form more crackles, increase slag, shortens the processing time per tank slag, reduces autoclave pressure and slag ladle
Configure quantity；Slag intensity after cooling is reduced, reduces and is crushed power consumption.Solid slag is not required to setting cooling tube.For example, broken through overheating
Broken steel, scum.
