9. aluminium alloy as claimed in any one of claims 1 to 8 concentrates the installation and debugging method of melting furnace liquid outlet limiting device,
It is characterized by: the installation and debugging method the following steps are included:
Step 1: the concrete structure of pedestal (3) is poured
Aluminium alloy is concentrated after melting furnace (1) position installs, dug out below liquid outlet (2) length, width and height be respectively 2 meters × 4 meters ×
3 meters of cube library pours out the concrete structure with a thickness of 0.2 meter based on described cube of library, solidifying to the concrete structure
Gu after, the formwork for placing of pedestal (3) is built on the basis of the concrete structure, is poured in the formwork for placing later strong
The strong concrete that grade is C60~C90 is spent, removes cast template after strong concrete solidification；
Step 2: debugging and mounting and fixing support (6)
Substrate (61) U-shaped on the fixed frame (6) is steadily buckled on relatively narrow one section of pedestal (3)；Asbestos plug is covered described
It on the conehead (41) of mandril (4) and blocks up tight liquid outlet (2), mandril (4) tail portion is fallen in into the first groove (68) in the middle part of fixed frame (6)
It is interior；It is that reference moves fixed frame (6) position in pedestal (3) length direction with mandril (4) upper limit position block (44), so that U-shaped substrate
(61) side is adjacent to limited block (44), and the fixed frame (6) is located between limited block (44) and threaded portion (43)；It hereafter will be U-shaped
Substrate (61) is bolted on relatively narrow one section of pedestal (3) of two sides；
Step 3: the limit effect of debugging mandril (4)
S1, the conehead (41) being placed on asbestos plug on the mandril (4) are blocked up asbestos plug in the aluminium by mandril (4)
Alloy concentrates the liquid outlet (2) of melting furnace (1), puts down the first groove (68) on mandril (4) to fixed frame (6)；
S2, rotation simultaneously adjust the limiter (5) compressed spring (53) contraction on the position on mandril (4) to limiter (5)
Outside elastic force is formed, so that fixed frame (6) is clamped between limited block (44) and limiter (5)；
S3, the rotating closed limit plate (63) to the opening (64) are placed on shape of a hoof lock pillar (66), and leak out the shape of a hoof
Wave pin is inserted into lock pillar (66) middle and upper part aperture in the opening, i.e. locking mandril (4) position；
S4, when needing to release molten aluminum, first S3 Wave pin is extracted out, rotates and opens limit plate (63) to described limit plate
(63) permanent magnet (69) is adsorbed on the vertical edge of L-type lock pillar (62)；
S5, be that fulcrum is lifted mandril (4) upwards with conehead (41) on the mandril (4), after be quickly drawn out mandril (4) and take cone out of
The asbestos plug of head (41) end.
