Description
Technical field
The utility model relates to a kind of composite material, relates in particular to the compound corrosion-resistant steel bar of a kind of stainless steel.
Background technology
Reinforcing bar is the important raw and processed materials that building trade is produced steel concrete, and reinforcing bar adopts carbon steel material production at present, and corrosion of steel bar is the one of the main reasons that causes reinforced concrete structure durability to lose efficacy.In order to improve the decay resistance of building structure, in some important structures, as the bridge on seashore, steel work building, overpass bridge etc., the employing that has stainless steel rebar, having overcome the carbon steel reinforcing bar often uses in the environment of snow melt salt at seawater and needs, chlorion sees through concrete contact reinforcing bar, thereby produces the drawback of corrosion.Simultaneously, also can avoid the calcium hydroxide in carbon dioxide in air and the cement, issue biochemical effect, generate calcium carbonate and water, reduce concrete basicity, weaken protective effect, cause corrosion of steel bar reinforcing bar in the condition that has water to exist.Contain elements such as rare, valuable Cr, Ni in the stainless steel, cost is higher, has limited it and has applied.People have carried out special design in order to improve the decay resistance of carbon steel reinforcing bar to alloying component.As Chinese publication number is the patent " a kind of vanadium high-strength corrosion-resistant steel bar steel and production technology thereof of containing " of CN101144136, its alloying element (%) is by weight percentage counted, 0.17-0.24C, 0.55-0.75Si, 1.35-1.50Mn, 0.04-0.10V, 0.04-0.10Re, all the other are Fe and impurity element.China's publication number is the patent " a kind of steel for niobium-containing high-strength corrosion-resistant steel bar and rolling mill practice thereof " of CN101144137, its alloying element (%) is by weight percentage counted, 0.17-0.24C, 0.55-0.75Si, 1.35-1.50Mn, 0.02-0.04Nb, 0.04-0.10%Re, all the other are Fe and impurity element.The reinforcing bar of above-mentioned two utility models is compared with plain bars, has better decay resistance under environment such as villaumite, industrial atmosphere, and cost of production is low, production technology is simple.By optimizing the alloying component of carbon steel reinforcing bar, though can improve its decay resistance, improve limitedly, be difficult to reach the effect of stainless steel rebar.
Along with the minimizing gradually of resources such as Ni, Cr, stainless cost of production can improve constantly, and therefore seeks both to have the decay resistance of stainless steel rebar, and the material that with low cost again, intensity also is higher than stainless steel rebar is the urgent targets of pursuing of people.The cost of mild steel, low-alloy steel is low, intensity is high, stainless steel has excellent decay resistance, with mild steel or low-alloy steel and the compound stainless steel composite muscle of preparing of stainless steel, significant for the application life of improving construction engineering quality, prolongation building structure.
The utility model content
The utility model is in order to solve the stainless steel rebar good corrosion resistance, but the cost height; Carbon steel reinforcing bar cost is low, but the problem of corrosion-resistant provides a kind of stainless steel compound corrosion-resistant steel bar, and it can obtain corrosion resistance and good, and cost is low, the reinforcing bar that can produce in batches.
For achieving the above object, the utility model adopts following technical scheme:
The compound corrosion-resistant steel bar of a kind of stainless steel, bar diameter are 6mm ~ 40mm, and it mainly is made up of the stainless steel alloy layer that coats along the core metal length direction around core metal and its, metallurgical binding between the two, and the thickness of stainless steel alloy layer is 1mm ~ 10mm.
Described core metal is any one in mild steel, the low-alloy steel.
Described stainless steel alloy layer is existing austenitic stainless steel, martensitic stain less steel, ferritic stainless steel or two phase stainless steel.A kind of in the preferred austenitic stainless steel.
The profile of the utility model reinforcing bar is identical with existing reinforcing bar, promptly is one of plain steel-bar, Ribbed Bar, steel wire, cold-rolled torsion steel bar, preferred Ribbed Bar.
The utility model implements to have following positive effect:
(1) the compound corrosion-resistant steel bar core of stainless steel adopts carbon steel, has guaranteed that reinforcing bar has higher intensity, good toughness and plasticity.
(2) stainless steel layer is preset on the compound corrosion-resistant steel bar of stainless steel surface, make reinforcing bar have excellent decay resistance, can be widely used in the steel work that is exposed under high chloride ion or the corrosivity industrial environment, the road that uses Snow Agent and bridge, ocean enclosure wall or fortification, coastal steel work, underground passage, the steel concrete etc., significantly improve its decay resistance, improve the life-span and the safety of structure.The thickness of stainless steel layer can be at 1mm to adjusting between the 10mm, to satisfy the requirement in different application lifes of different corrosion-resistant operating modes flexibly.
(3) be metallurgical binding between stainless steel and the carbon steel, the bond strength height does not come off, and the life-span is long.
(4) stainless steel layer can be designed to different compositions with the core carbon steel, can be applicable to the various operating modes of different corrosive mediums, different operating temperature, and its applicable surface is wider.
(5) the compound corrosion-resistant steel bar production technology of stainless steel is simple, and equipment investment is few, can produce continuously, and production efficiency is higher.
