SAEJ2340HR550x

SAEJ2340 HR550x pickling board is a high-quality hot-rolled sheet for raw materials, pickling to remove the oxide layer, after trimming, finishing, surface quality and use requirements (primarily roll forming or stamping performance) between the hot-rolled sheet and intermediate product between cold-rolled plate, hot-rolled sheet and is part of the cold rolled sheet ideal alternative. Compared with hot-rolled plates, pickling board main advantages: 1) good surface quality, hot rolled pickled sheet removes surface oxide scale, improve the surface quality of steel, easy welding, oiled and painted. 2) high dimensional accuracy, after formation, the occurrence of certain changes can plate, thereby reducing the unevenness of bias. 3) improve the surface finish and enhanced appearance. 4) reduce environmental pollution caused by pickling dispersed users. Compared with cold rolled sheet, plate pickling advantage lies in ensuring the surface quality requirements under the premise, allowing users to effectively reduce procurement costs. Currently, many companies high-performance steels, low-cost higher and higher requirements. With rolling technology advances, the positive performance of hot-rolled sheet cold-rolled sheet close, so that the "heat generation of cold" technically be achieved. It can be said, pickled sheet is between the price-performance cold rolled and hot-rolled plate of a product is relatively high, with good market prospects. But for the moment, pickling board in various industries use our just started, professional pickling plate production from September 2001, Baosteel pickling production line begins. Pickling plate market is mainly reflected in the following four areas: Alternative cold-rolled, hot-rolled substitution, import substitution and alternative small pickling. Where import substitution and small pickling actually existing market, limited market can not be completely replaced. With the rapid development of automobile, machinery, light industry, enterprises are facing competition in this market, the enormous pressure on product costs and increasing product quality requirements, pickling board its high cost completely replace part cold plates and hot plates, will gradually accepted by the user. The main processes are pickling hot-rolled plate laser welding, straightening bit stretched, turbulence pickling, smooth line, trimming, online coating oil. Baoshan Iron and Steel Pickling size is generally 1.0-6.1 * 800-1650mm. Products include low and medium and high intensity level of stamping steel, automotive structural steel, mainly in coil form of delivery. Process characteristics with hydrochloric acid on iron oxide skin hot rolled steel sheet obtained after clearing nice, smooth surface. Features 1, reduce costs, instead of the cold-rolled plate pickling plate, cost savings for the enterprise. 2, good surface quality, compared with ordinary hot-rolled plate, hot-rolled pickled sheet removes surface oxide scale, improve the surface quality of steel, easy welding, oiled and painted. 3, high dimensional accuracy, after formation, the occurrence of certain changes can plate, thereby reducing the unevenness of bias. 4, to improve the surface finish and enhanced appearance 0
