Good quality nm450 wear-resistance steel plate export to world

Our company mainly produce automobile steel plates, ordinary carbon low-alloy steel, container plates, ship plates, container plates, weathering steel, petroleum pipes, pipeline steel, NM450 wear-resistance steel plate cold-rolled silicon steel, etc., which are widely used in various fields of the national economy.The BEBON brand is not only a symbol of strength, but also an embodiment of wisdom.Since it was established in 2000. Based on the domestic rich NM450 wear-resistance steel plate product resources and the great steel demand of the international market, our NM450 wear-resistance steel plate service has already spread many countries in Europe , America, Southeast Asia, Middle East, South America, Africa, etc, and we have won an outstanding reputation for its professional exporting steel productsS355J2 steel plate rolling process is controlled rolling process. In the rolling process, the ingot rolling temperature is 1000-1050℃; in the first stage, the low-speed and large reduction rolling process is adopted, the high-temperature stage is 950-1000℃, the NM450 wear-resistance steel plate rolling speed is 1.6-2.0m/s, the single reduction rate is 15-20%, and the cumulative reduction rate is 40-45%, so as to ensure sufficient deformation of ingot. In the first stage, the start rolling temperature is 910-930℃, and the finish rolling temperature is ≤ 870℃.As a basic building material, steel plates are currently widely used in automobiles, shipbuilding, chemical industry, aerospace and other fields. Reasonable selection of flaw detection methods to ensure the quality of NM450 wear-resistance steel plate steel plates is of great significance to safe production. Common defects of steel plates are folding, inclusion, shrinkage, air bubbles, delamination and cracks. These problems can be discovered in time through flaw detection.Under the action of the roller and the plug, a cavity is formed in the blank, which is called the blank. Then send it to the automatic tube rolling machine to continue rolling. Finally, the wall thickness of the whole machine is equalized and the diameter is calibrated by the sizing machine to meet the specification requirements. It is an advanced method to produce NM450 wear-resistance steel plate, hot-rolled seamless steel tube by continuous rolling mill.The after-sales service department will pay return visit to each customer by call or email, report problems found during the return visit in time, and discuss with the production and quality inspection center to propose effective solutions and follow up in a timely manner, so as to ensure the benefits each customer are fully guaranteed, and to provide customers with more value-added services.
