Abstract
本发明属于热浸镀镀层钢板技术领域，具体涉及一种超深冲用热浸镀锌铝镁合金镀层钢板及其制备方法。现有热浸镀Zn‑Al‑Mg合金镀层钢板不能完全满足深冲零部件的使用要求的问题，本发明提供了一种超深冲用热浸镀锌铝镁合金镀层钢板，由钢基和镀层组成，镀层的主要成分为：按重量百分比计，铝0.8～2.5％，镁0.8～2.0％，微量合金元素0.02～0.20％，其余为锌及不可避免的杂质，其中的微量合金中包含≥0.02％的钒。本发明通过钢基严格控制C、S、P等杂质元素和Ti、Nb元素的添加，Ti与Nb固溶杂质元素，避免了钢基表面杂质元素促进镀层中脆相ζ相的生长，提高了镀层的成形性，进而提高了钢的深冲性能，具有很好的实用价值。The invention belongs to the technical field of hot-dip galvanized coated steel sheets, in particular to a hot-dip galvanized aluminum-magnesium alloy coated steel sheet for ultra-deep drawing and a preparation method thereof. The existing hot-dip galvanized Zn-Al-Mg alloy-coated steel sheet cannot fully meet the use requirements of deep-drawing parts. The composition of the coating, the main components of the coating are: by weight percentage, aluminum 0.8-2.5%, magnesium 0.8-2.0%, trace alloying elements 0.02-0.20%, the rest are zinc and inevitable impurities, and the trace alloy contains ≥ 0.02% vanadium. The invention strictly controls the addition of C, S, P and other impurity elements and Ti, Nb elements through the steel base, and the solid solution impurity elements of Ti and Nb avoids the impurity elements on the surface of the steel base to promote the growth of the brittle phase ζ phase in the coating, and improves the The formability of the coating layer, thereby improving the deep drawing performance of the steel, has good practical value.
Description
Technical Field
The invention belongs to the technical field of hot-dip coated steel plates, and particularly relates to a hot-dip zinc-aluminum-magnesium alloy coated steel plate for ultra-deep drawing and a preparation method thereof.
Background
The Zn-Al-Mg alloy coating has attracted wide attention abroad in the 80 s of the 20 th century, and becomes a research focus in the professional field of hot dip galvanizing and zinc alloy coating. From the research results of the same lines at home and abroad, the hot-dip galvanized Zn-Al-Mg alloy coated steel plate added with Mg has better corrosion resistance under the condition that the contents of Zn and Al of the coatings are at the same level, and the processing application performance (formability, weldability and paintability) of the material is excellent, so that the hot-dip galvanized Zn-Al-Mg alloy coated steel plate can replace the existing corresponding hot-dip galvanized or zinc alloy coated steel plate, and has very wide market demand prospect.
The hot dip Zn-Al-Mg alloy coated steel plate is mainly applied to the building industry at present, and is gradually popularized and applied to the industries of household appliances, automobile manufacturing and the like. The research on the Zn-Al-Mg alloy coating in China is late, and only enterprises such as Bao steel, saddle steel, wine steel and Shandongkui at present put forward the hot dip Zn-Al-Mg alloy coating steel plate.
The existing hot dip Zn-Al-Mg alloy coated steel plate can be divided into three types of low aluminum (W Al is less than 5 percent), medium aluminum (W Al is more than or equal to 5 percent and less than 13 percent) and high aluminum (W Al is more than or equal to 47 percent and less than or equal to 57 percent). For different varieties of Zn-Al-Mg alloy coating steel plates, the contents of Al and Mg in the coatings are different, and the organizational structure and the quality performance of the coatings are different, so the application fields are different. As the content of Al and Mg increases, the corrosion resistance of the plating layer increases, but the formability and weldability decrease. In the field of household appliance and automobile application, in order to ensure that a Zn-Al-Mg alloy coating steel plate meets the punch forming requirement of a user, a low-aluminum component system is required to have good formability. However, after the low-aluminum Zn-Al-Mg alloy coating steel plate is bent and formed, macroscopic microcracks still exist, and in order to meet the deep drawing requirements of users, the forming performance of the coating needs to be further improved.
Patent CN111519117A provides a high surface quality zinc-aluminum-magnesium steel plate with excellent blackening resistance and a production method thereof, the plating solution comprises the following components: 1.0-3.0% of Al, 1.0-3.0% of Mg1.0, 0.005-0.055% of Cu, 0.005-0.035% of Ti, 0.05-1.0% of Si, and the balance of Zn and inevitable impurities. The temperature of the plating solution is 410-460 ℃, and the temperature of the strip steel entering the pot is 400-480 ℃. Cooling at the speed of 10-30 ℃/s after plating, and cooling the plate to be not higher than 200 ℃; the temperature of the front plate is not higher than 80 ℃ before entering the quenching tank, and the front plate enters the quenching tank to be cooled to be not higher than 40 ℃.
