Abstract
The invention relates to a trunnion imbedding method of a metallurgical slag pot. A processed trunnion is cast on a slag pot body to complete casting of the trunnion and the slag pot body when the slag pot body is cast. The trunnion imbedding method comprises the following steps of (1) preparing an outer sand mould; namely transversely embedding the processed trunnion in the sand mould, and stretching an inside end of the trunnion into a cavity of the outer sand mould; and (2) enabling the outer sand mould to be sleeved on an inner sand mould, casting molten steel in a cavity between an outer sand mould model and an inner sand mould model, casting the trunnion on the slag pot body, removing the sand moulds after cooling, and completing the casting of the trunnion and the slag pot body. The trunnion imbedding method is simple in operation, high in work efficiency, short in production period and low in production cost.
Description
Technical field
The present invention relates to a kind of field of metallurgy method, relate in particular to a kind of metallurgical slag and fill with the gudgeon embedding method.
Background technology
Slag ladle is the container for the various high-temperature liquid state slags of splendid attire, is the key equipment of metal smelt.Gudgeon is again the key position of slag ladle, is bearing handling and the tilt functions of slag ladle, and is very strict to its reliability requirement, and this just requires the gudgeon structures surrounding fine and close.In addition, in residues processing technique, slag ladle and carriage loading and unloading slag ladle and the slag ladle of tumbling all are automatically to finish by hydraulic drive, so the relative dimensions of gudgeon and the structure of tumbling is had relatively high expectations.
The casting technique that existing gudgeon and slag are filled with body has two kinds: the first is first gudgeon 4 to be processed, and processes hole and the corresponding bolt hole of crossing win with gudgeon at slag ladle body 7 again, and is fixing with bolt 11 again after at last gudgeon 4 being installed.This technique was owing to required to win cooperation, and machining accuracy is high, and processing charges is high, the cycle is long, and bolt is very easily loosening in the use procedure, has larger potential safety hazard (see figure 2).The second is with slag ladle body 7 and gudgeon 4 monoblock casts.This technique is to fill with the radially somatotype of body 7 with the center line of gudgeon at slag, locates to lay the gudgeon 4 that processes at the gudgeon core print (2# core 9,3# core 10) of setting after the molding, then mould assembling cast, and gudgeon 4 tolerances can't guarantee (see figure 1); And after the slag ladle monoblock cast, gudgeon 4 is processed, processing charges is high, the cycle is long again, and gudgeon 4 portion of tissue are fine and close not, have shrinkage porosite 12, therefore has larger potential safety hazard (see figure 3).
No matter adopt what method insert gudgeon, all need gudgeon and slag ladle body are carried out machined, and because the limitation of casting technique, can cause around the gudgeon and the gudgeon institutional framework not fine and close, the more important thing is that the production cycle is long, the production cost height.Therefore, we are in the urgent need to a kind of unique casting technique of slag ladle gudgeon insert, with guarantee around the gudgeon and the gudgeon institutional framework fine and close, and easy and simple to handle, the production efficiency height.
Summary of the invention
Technical problem to be solved by this invention provides a kind of simple to operate, and production efficiency is high, and is with short production cycle, and the metallurgical slag that cost is low is filled with the gudgeon embedding method.
The technical solution adopted in the present invention is: a kind of metallurgical slag is filled with the gudgeon embedding method, and it is when the slag ladle body casting, and the gudgeon that processes is cast on the slag ladle body, finishes the castingin that gudgeon and slag are filled with body.Adopt the precision of the gudgeon of the method casting can satisfy the slag ladle of the Special use working condition requirement such as slag basin transport vehicle.
Press such scheme, it may further comprise the steps:
The step of step (1), the outer sand mold of preparation, it comprises that the gudgeon that will process laterally buries and is placed in the sand mold that the medial extremity of gudgeon stretches in the outer sand mold chamber;
Step (2), outer sand mold is enclosed within on the interior core, molten steel casting outside in the chamber between sand mold and the interior core, is cast in gudgeon on the slag ladle body; After the cooling, remove sand mold, finish the castingin that gudgeon and slag are filled with body.
Press such scheme, step (1) is specially:
Utilize sandbox, the inboard metal pattern in the outside and be enclosed within the outer sand mold of trunnion base wooden model preparation of the medial extremity root of gudgeon, gudgeon and trunnion base wooden model laterally bury in the sand mold that is placed on sandbox and metal pattern, and the medial extremity of the medial extremity of gudgeon and trunnion base wooden model contacts with metal pattern; After the sand mold sclerosis, slough successively metal pattern and trunnion base wooden model, make outer sand mold.
Press such scheme, described metal pattern is provided with the groove for the trunnion pivot inboard, is provided with the support bar for the trunnion pivot downside between described sandbox and the metal pattern;
In the step (1), the end of described gudgeon outboard end is placed on the described support bar, and described gudgeon inboard is placed on the described groove, is filled between sandbox and the metal pattern with molding sand again, gudgeon and trunnion base wooden model is buried be placed in the outer sand mold.
Among the present invention, the slag of the profile of described metal pattern and size and corresponding need casting is filled with the shape and size identical (add casting and stretch chi) of body; Gudgeon and sandbox are reinforced the connection (realizing by welding), can avoid the drift of gudgeon in casting process, guarantee the dimensional accuracy of gudgeon and slag filling body.
The present invention can guarantee gudgeon tolerance and gudgeon position density effectively by optimizing the casting method of castingin gudgeon, and gudgeon and slag are filled with the bound fraction of main body near the fusion state, the use that slag is filled with is guaranteed safely, and simple to operate, production efficiency is high, and is with short production cycle.Owing to only gudgeon and its embedded part are carried out machined, have significantly reduced the machined expense in the slag filling production process.
Beneficial effect of the present invention is:
Gudgeon compact structure and intensity all increased when 1, gudgeon adopted imbedding process, and gudgeon and slag are filled with body and approached fusion, and slag is filled in the use procedure and can become flexible, and has effectively guaranteed use safety;
2, owing to adopted the locate mode of groove and support bar, in the type process processed gudgeon lay simple to operately, the relevant position dimensional accuracy of gudgeon is higher, and has guaranteed not drift in casting process, can reach fully≤tolerance of 2mm, satisfy the instructions for use that slag is filled with;
3, saved slag and filled with the integrated machine manufacturing procedure, reduced the manufacturing cost that slag is filled with, shortened the manufacturing cycle that slag is filled with, improved production efficiency, can fill with manufacturing enterprise to all kinds of slags and be applicable.
