Abstract
A vanadium-containing hot-rolled pickling plate and its pickling method, its chemical composition and mass percentage are: C: 0.180-0.250%, Mn: 0.150-0.250%, Si≤0.10%, P≤0.025%, S≤0.015%, V: 0.035~0.060%, N≤0.0060%, Cr≤0.30%, Ni≤0.30%, Cu≤0.30%, the balance is Fe and unavoidable impurities. Pickling methods include welding, scale breaking, pickling, rinsing, drying, smoothing, oiling, and coiling. The invention adopts reasonable composition design and efficient pickling process, and the obtained hot-rolled pickling plate has high strength and good welding performance, and is suitable for girders, seat slide rails, structural parts, etc. of new energy vehicles, and is ideal for lightweight vehicles Material.
Description
Technical field [0001] The present invention belongs to the technical field of metallurgy, in particular to a pickling hot-rolled sheet and vanadium-containing pickling. Background technique [0002] Pickling hot-rolled sheet is increasingly recognized by the market, not only because the cost of production is lower than cold-rolled sheet, but also because of its mechanical properties and surface quality in the continuous development of technology, has been effectively protected under production control capabilities continue to improve the background, so pickling the hot rolled sheet in some areas of buildings, appliances, cars, etc. can completely replace cold-rolled sheet. Vanadium-containing hot-rolled sheet has two advantages: First, effectively enhance the strength of steel, and second, to enhance the weldability of products, it can be used as the material of choice for new energy lightweight vehicles. [0003] Vanadium-containing acid in the production process of different p...
