The хардокс 450 steel wear resistance is rolled into 20mm pipe

Peritectic reaction often occurs in the process of cooling and solidification of wear-resistant steel plate, хардокс 450 steel wear resistance, and accompanied by this reaction, there will be greater volume change and linear shrinkage, which is mainly due to the hot cracking of continuous casting slab in the casting process. In the mold, the heat load transmitted from the billet is too much or uneven around the meniscus of molten steel, resulting in uneven heating, which is more likely to produce longitudinal cracks.

In the second step of hot rolling process, different finished mills are used to roll billets or continuous casting billets into finished steel of proper shape and size. This хардокс 450 steel wear resistance production process is called finished product production, which is generally divided into two stages of rough rolling and finish rolling. In the roughing stage, a large amount of reduction (reduction per pass) is adopted to reduce the number of passes and improve the output; after roughing, the finishing stage is entered, and the finishing is carried out with a small amount of reduction to achieve a good surface and accurate хардокс 450 steel wear resistance size.

The company produces and export steel plates and steel section products of various materials all year round. The width of the хардокс 450 steel wear resistance thin plate is 500 - 1500 mm; the width of the thick plate is 600 - 3000 mm. Steel plates are classified by steel type, including ordinary steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, bearing steel, etc .; according to use, there are shipbuilding plate, pressure vessel plate, wear resistant steel plate, bridge builidng steel, corten steel plate, and pipeline steel plate.

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 хардокс 450 steel wear resistance, hot-rolled seamless steel tube by continuous rolling mill.
