Abstract
The invention relates to a lead-contained anticorrosion soft magnetic alloy which comprises the following components in percentage by weight: not less than 1.2 percent and not more than 2.3 percent of Si, not less than 0.10 percent and not more than 0.50 percent of Ni, not less than 12.0 percent and not more than 15.0 percent of Cr, not less than 0.07 percent and not more than 0.30 percent of Pb, not less than 0.20 percent and not more than 0.60 percent of Mo, not more than 0.025 percent of Al and the balance of Fe. Because medium and small sectional anticorrosion soft magnetic alloys with the diameter of 8-42 mm are produced by adopting horizontal continuous casting and direct continuous casting in the invention, shrinkage exists in the solidifying process, the effective supplementation of an intermediate cladding steel liquid can be obtained, centralized hole shrinkage does not exist, the yield of a continuous casting cast material can be improved by about 10-15 percent by being compared with a traditional molded casting process, not only the production cost is greatly lowered, the quality is similar to that of vacuum furnace smelting, high efficiency and energy saving are achieved, and the selling price can be reduced by about ten thousand Yuan/ton by being compared with a similar material, but also import can be replaced, and the price and the quality of products also have the export competitive advantages superior to similar products in an international market.
Description
Technical field
The present invention relates to the non-retentive alloy in metallurgical material field, particularly a kind of grade of steel is 00Cr13Si
2The lead-free anti-corrosion soft magnetic alloy of MoPb.
Background technology
The existing anticorrosion soft mag standard GB/T 14986-94 alloy designations of China has only 1J36,1J116 and three trade mark products of 1J117.And in recent years, along with the development of automatic control, telemanipulator, with the magnetic valve be representative various controls with the use of setters just more and more widely.For the miniaturization that reaches setter, the purpose of ratio controlization, require also more and more higher to reliability of material.Simultaneously along with the spreading all over of working methods such as high speed cuttingization, high-accuracyization, the diversified direction of forward that requires of material singularity is developed.And above-mentioned three kinds of old-nationals produce the requirement that trade mark product not exclusively is suitable for market, and its market is progressively captured by Japanese trade mark K-M31, K-M35F and German trade mark 4105IL, 4105IA, U.S. 430FR, imported materials and items such as Italian trade mark MG1, MG2.In order to substitute import, quicken the production domesticization of magnetically soft alloy material, domestic " Wuhan Metallurgical Inst. " succeeds in developing a kind of grade of steel in nineteen ninety-five is 00Cr13Si
2The stainless steel soft magnetic alloy, make water control water heater safety valve core of the electromagnetic valve to substitute Japanese imported materials and items, but because its production technique that adopts adds electroslag remelting duplex steelmaking ingot casting for the intermediate frequency furnace melting, again through heat forge, hot rolling, thermal treatment, pickling, draw dial, operation processing such as alignment, polishing, operation is many, lumber recovery is low, and production cost is high and eliminated by market; Daye special steel 1999 was through 40 days meticulous development, and successfully adopting electric arc furnace smelting to go out the first stove grade of steel is 00Cr13Si
2Steel after, also because of this steel grade requires that carbon content is low, silicone content is high, composition narrow range, the difficult control of smelting chemical composition fail to carry out the marketization.
Summary of the invention
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art, and adopt the supporting small-sized horizontal caster of " a kind of stainless steel continuous casting a refining unit " patented technology, directly continuous casting is produced the light-gauge lead-free anti-corrosion soft magnetic alloy of φ 8～φ 42mm.
Technical scheme of the present invention is: a kind of lead-contained anticorrosion soft magnetic alloy, by weight percentage, it contains following composition: 1.2%≤Si≤2.3%, 0.10%≤Ni≤0.50%, 12.0%≤Cr≤15.0%, 0.07%≤Pb≤0.30%, 0.20%≤Mo≤0.60%, Al≤0.025%, surplus are Fe.
Also contain the C that is no more than 0.035% weight in the above-mentioned alloy.
Also contain 0.035% the P that is no more than weight in the above-mentioned alloy.
Also contain in the above-mentioned alloy and be no more than 0.030% S.
Also contain in the above-mentioned alloy and be no more than 0.50% Mn.
The present invention is owing to having saved valuable rare metal Ni and Cr, so low price; The Cr and micro-Mo, the Ni that contain 12-15% belong to the stainless steel category, and its solidity to corrosion is good; Contain the Si more than 1.2%, iron loss is descended, promote grain growth, Hc is descended widely, it is more stable that magnetic property becomes, and increases resistivity, μ improved, thereby have higher Bs under weak magnetic environment; Contain Pb and easily cut element, and reduced Al content, so be difficult for sticking cutter, machinability is good, can be used for the numerically-controlled machine processing of high speed cuttingization, and the production efficiency height is suitable for doing and needs the electromagnetism of excellent cutting performance valve actuation iron core to use.
The present invention is owing to adopt " a kind of stainless steel continuous casting a refining unit " patented technology (patent No.: ZL96249589.1) supporting small-sized horizontal caster, directly continuous casting is produced light section anticorrosion soft mag among φ 8～φ 42mm, production process is simple, the argon gas refining, the sealing casting, contraction in process of setting can access effectively replenishing of tundish molten steel, there is not concentrated shrinkage cavity, the casting material of continuous casting can improve lumber recovery about 10～15% than traditional die casting process, both significantly reduced production cost, quality is similar to vacuum oven again and smelts, energy-efficient, price can reduce nearly ten thousand yuan/ton than same type of material, not only substitutes import, also makes the price of product and quality possess the export competition advantage that is better than the world market like product.
Below in conjunction with embodiment detailed content of the present invention is further described.
