Abstract
The utility model relates to a composite stainless steel. The utility model is characterized in that the external surface of round or square or flat normal carbon steel (2) is compounded with a stainless steer layer (1) in order to constitute a round or square or flat composite stainless steel. The composite stainless steel can replace a plurality of stainless steels, saves a plurality of stainless steel resources, reduces production cost to great extent, and enlarges the applicable range of stainless steel. Furthermore, the product has the advantages and effects of stable quality, being suitable for large-scale production, simple operation, and small fixed investment.
Description
Technical field
The utility model relates to a kind of composite stainless steel, belongs to the metallurgical processing technical field.
Background of invention
Stainless steel is a human being's production, the indispensable commodity of living, along with the development speed acceleration of society, the stainless steel demand is increasing, but because stainless price is more expensive, the chromium of needed raw material, nickel all are that rare metal is limited by reserves again, and therefore stainless output and demand also are restricted.
Summary of the invention
The purpose of this utility model is to understand the contradiction of stainless output and demand of soaking through just, and designs a kind of composite stainless steel, thereby can replace a large amount of stainless steels and save the stainless steel resource, satisfies the needs of human being's production, life.
The purpose of this utility model realizes by following technical proposal:
Composite stainless steel is characterized in that forming at circular or the square or compound one deck stainless steel layer of outer surface flat straight carbon steel (2) (1) composite stainless steel of circular or square or flat.
The circular straight carbon steel diameter of described circular composite stainless steel is 5-30mm, and stainless steel layer thickness is the 10-30% of straight carbon steel diameter length; The square straight carbon steel cross section length of side of described square composite stainless steel is 10-30mm, and stainless steel layer thickness is the 10-30% of the square straight carbon steel cross section length of side; The flat straight carbon steel section thickness of described flat composite stainless steel is 2-10mm, and width is 15-300mm, and stainless steel layer thickness is the 10-30% of flat straight carbon steel section thickness.
Can replace a large amount of stainless steels owing to take technique scheme that compared with the prior art the utility model is had, save a large amount of stainless steel resources, reduce production costs significantly, enlarge the stainless scope of application, constant product quality, wide in variety, be fit to large-scale production, simple to operate, processing charges is low, advantage that investment in fixed assets is few and effect.
Description of drawings
Fig. 1 is the circular composite stainless steel structural representation of the utility model,
Fig. 2 is the square composite stainless steel structural representation of the utility model,
Fig. 3 is the utility model flat composite stainless steel structural representation.
The specific embodiment
Composite stainless steel, by Fig. 1, Fig. 2, shown in Figure 3, the composite stainless steel of forming circular or square or flat at circular or square or the compound one deck stainless steel layer of outer surface flat straight carbon steel (2) (1), its circular composite stainless steel, by shown in Figure 1, its circular straight carbon steel diameter is 5-30mm, and stainless steel layer thickness is the 10-30% of circular straight carbon steel diameter length; Its square composite stainless steel, by shown in Figure 2, its square straight carbon steel cross section edge lengths is 10-30mm, stainless steel layer thickness is the 10-30% of square straight carbon steel cross section edge lengths; Its flat composite stainless steel, by shown in Figure 3, its flat straight carbon steel section thickness is 2-10mm, and width is 15-300mm, and stainless steel layer thickness is the 10-30% of flat straight carbon steel section thickness.
When making composite stainless steel, stainless steel water with the 1650-1750 degree injects in the type tube of centrifugal casting machine earlier, form circular stainless steel crystallizing layer immediately, and then the straight carbon steel water of 1500-1600 degree high melt injected circular stainless steel crystallizing layer inside, stainless steel water and straight carbon steel water at high temperature are combined into one, with the straight carbon steel and the compound stainless steel base of stainless steel of circle, demoulding is rolled into circular composite stainless steel through the 1150-1200 degree more after cooling.Be rolled into square more circular composite stainless steel base or the flat composite stainless steel.
