Abstract
The utility model discloses a centrifugally cast and molded centrifuge drum, which comprises a drum body. The drum body is integrally cast and molded by adopting a centrifugal casting technique and a static molding technique. The inner chamber of the drum body is conical. The drum is made of stainless steel. Compared with the existing drum, by adopting the centrifugal casting technique and the static molding technique to integrally cast and mold the drum, the conical inner chamber of the drum is conical and is not welded, the defects of air hole sand inclusion, slag inclusion, cracks and the like can be effectively eliminated, the potential safety hazards brought to equipment are avoided, the service life of the equipment is prolonged, the production cycle is short and the finished product rate is high.
Description
Technical field
The utility model relates to a kind of rotary drum, relates in particular to a kind of bowl of centrifugal casting forming.
Background technology
What existing domestic centrifugal reel adopted basically is stainless steel-like forging or stainless steel-like roll bending weldment, and the forging complex structure, the manufacturing cycle is long, manufacturing cost is very high.Therefore, domestic rotary drum is more with weldment especially, but because the weld seam of weldment becomes the source point of crackle and corrosion easily; Bring device security hidden danger; Cause service life of equipment to decline to a great extent, centrifuge is abroad made the field, has banned use of the bowl of welding at present.
Compared to the traditional vertical spun casting, straight in can only outer cone, realize inner tapered reliable machining; Cause processing cost very high, and lumber recovery is very low, finished product rate even less than 30%; To some special-shaped rotary drums, same manufacturing issue is arranged also.
The utility model content
To the problem that above-mentioned prior art exists, the utility model purpose is to provide the integrated poured moulding that combines of a kind of centrifugal casting technology and static foundry engieering, and surperficial and inner chamber all is the bowl of taper.
The technical scheme of the utility model is: a kind of bowl of centrifugal casting forming; Comprise the rotary drum body; Said rotary drum body adopts centrifugal casting technology and the integrated poured moulding of static foundry engieering, and said rotary drum chamber body is taper, and said rotary drum adopts stainless steel material to process.
As preferably, said rotary drum adopts super-low carbon stainless steel.
The beneficial effect of the utility model is:
1. compare with rolled steel coiled sheet weldering awl section, spun casting awl section rotary drum does not have the welding defective.(weld seam of weldment becomes the source point of crackle and corrosion easily, brings device security hidden danger, or causes service life of equipment to descend significantly).
2. compare with forging, the single-piece steel ingot of forging is difficult in steel mill customized in batches, even steel ingot is arranged, the forging die input amount of forging is big; Manufacturer is difficult to drop into, even drop into, the forging processing capacity that obtains is big, and recovery rate is very low; Manufacturer is difficult to bear, and the utility model convenience customized, less investment, processing capacity is little; Recovery rate is high, can promote finished product rate more than 20%, significantly reduces machining time, and integrated cost can reduce more than 30%.
3. compare with the product of static state casting, the product of the utility model has effectively been eliminated defectives such as pore burning into sand, slag inclusion, crackle, and mechanical property is also fine.
4. the utility model had both guaranteed the chemical composition of product, had also reached the basic mechanical performance of product.From the liquid steel refining to the centrifugal casting moulding, be linked to be a line production, quality, duration, cost can both satisfy customer requirements.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Among the figure: 1. rotary drum body.
The specific embodiment
Embodiment: as shown in Figure 1 as a kind of embodiment of the utility model, a kind of bowl of centrifugal casting forming; Comprise rotary drum body 1, said rotary drum body 1 adopts centrifugal casting technology and the integrated poured moulding of static foundry engieering, and said rotary drum chamber body is taper; Said rotary drum body 1 adopts stainless steel material to process, short, low cost of manufacture of manufacturing cycle, and integrated poured forming do not have pad; Do not have to cause in the use source point of crackle and corrosion, improve device security, service life of equipment is significantly risen; Said rotary drum body adopts low carbon stainless steel; The stainless steel material of perhaps having relatively high expectations through the material rate of AOD stove refining is processed, and has not only realized small lot, many variety production economically, the service life of also having improved rotary drum greatly; The vertical centrifugal machine awl section rotary drum pouring into a mould out particularly, processing capacity is few, yield rate is high, the inherent quality of product meets the requirements.
Technological process is following:
1. by requirement of client or technical protocol, adopt the means of refining, smelt qualified molten steel.
2. press the mechanical dimension of product drawing, design mould (type tube) and static sand casting mould.
3. by the vertical centrifugal casting requirement, design centrifugal casting pouring technology and sand casting process.
4. heat treatment: solution treatment.
5. check: chemical composition, mechanical property, carrying out flaw detection.
6. machining is the finished product workpiece.
7. check physical dimension.
8. pack.
Claims (2)
1. the bowl of a centrifugal casting forming; Comprise rotary drum body (1); It is characterized in that: said rotary drum body (1) adopts centrifugal casting technology and the integrated poured moulding of static foundry engieering, and said rotary drum body (1) inner chamber is taper, and said rotary drum adopts stainless steel material to process.
2. according to the bowl of the said a kind of centrifugal casting forming of claim 1, it is characterized in that: said rotary drum body (1) adopts super-low carbon stainless steel.
