Placing box between the placing box filled carries out filling lead again, and as shown in Figure 6, to drawing reference numeral, placing box 1., 2. enters successively
Row fills lead;Before filling lead, need first lead to be heated to 360 DEG C, then carry out deslagging process, then come out of the stove at 355 DEG C, then 340
DEG C time carry out fill lead operation;It addition, filling lead process uses from start to end the most progressively slows down filling lead speed;
The casting of B4, lead liquid to composition backing concordant time, stop casting and clear up the scum silica frost of liquid level;
B5, being made the cooling of lead liquid order from lower to upper carry out by insulation, lead liquid temp drops to supplement lead liquid when 310 DEG C to be carried out
Feeding, during supplementing lead liquid, supplements lead liquid and carries out below oxide layer;
B6, filling after lead completes until the one side of Os Draconis segmentation, another side is carried out filling lead by anti-body again, fills lead process and repeats above-mentioned B2-
B5 step.
First, in order to prevent Os Draconis from deforming, need workpiece is preheated before filling lead, after being preheated to about 100 DEG C more right
Keel structure single-frame carries out filling lead, no more than edge on composition backing when filling lead, so that prevent cannot lid side plate;Meanwhile, uniformly
Preheating can avoid the relatively Large deflection that Os Draconis cause during filling lead due to variations in temperature inequality;Should use up during filling lead
Amount avoids lead water temperature to decline too fast and cause filling lead uneven.Second, lead heating fusion temperature arrives about 360 DEG C and arranges
Slag, comes out of the stove for 355 DEG C, and about 340 DEG C carry out filling lead, and casting cycle suitably controls flow, first quick and back slow, the cleaning oxidation of casting limit, limit
Slag and impurity due in lead cooling procedure constriction coefficient bigger, constantly to carry out feeding during filling lead.3rd, lead liquid needs
Carry out being incubated and feeding: when lead liquid casting to composition backing is concordant, stop casting and clear up rapidly the scum silica frost of liquid level.Made by insulation
The cooling of lead liquid order from lower to upper is carried out, and lead liquid temp drops to about 310 DEG C to start to be continuously replenished lead liquid feeding in time;Mend
During filling lead liquid, in order to make the smooth of casting face, the oxide layer that liquid level is formed is not destroyed, and supplements lead liquid under oxide layer
Face is carried out, it is ensured that final lead face is smooth and the degree of compaction of lead body.4th, after the one side of Os Draconis has been cast, anti-body is again to separately
One side is alternately carried out casting to keel structure every one grade again after carrying out being preheated to about 100 DEG C and fills lead.5th, duct keel is tied
Structure fills the deviation with ± 6mm of the overall line style data after lead as standard value, and carries out Os Draconis amount of deflection and remember with centerline deviation data
Record.Thus improve the making precision of Os Draconis and fill lead degree of compaction.
Described Os Draconis manufacture method, when Os Draconis segmentation being closed up mouth and carrying out filling lead, in advance according to the chi closing up mouth
Very little casting makes lead;Until Os Draconis segment folding connect after, then the lead made in advance is put into close up mouth fix.Due to dragon
Bone segment folding is typically all and carries out in factory, and fills lead not in segment folding place, therefore closes up the Os Draconis one at mouth
Duan Wufa casts, so lead need to be first cast into according to the actual size closing up mouth in Foundry Works workshop, is then being transported to now
Field lifting puts in place.The both sides of lead can cast a little hanger more, close up the Os Draconis top board at mouth, weldering first installed by base plate, web
Connecing, lid biside plate again after lead stamp installation, lead stamp is installed and is used baking to be finely adjusted lead stamp when there is deviation to reinvent again
Install.The method can improve the convenience that Os Draconis make, more to adapt to make restriction and the field fabrication demand in place.
