Whether nm450 plate impact resistance need preheating

The advantages of NM450 plate impact resistance, steel plate produced from coil: price is cheap and length can be freely determined; transportation is convenient, no need to consider according to the size of steel plate; cutting is convenient, according to the actual needs of steel plate size cutting, and finally can effectively save materials. The disadvantage of steel plate produced from coil: there will be great welding deformation during welding, which is difficult to adjust. Therefore, the steel plate produced from coil can not be used for parts with high requirements on appearance quality.

The company has allocated special environmental protection facilities for all NM450 plate impact resistance pollution sources, strengthened the recycling of waste resources and improved the efficiency of resource utilization. At present, the recovery and utilization rate of solid wastes such as iron slag, steel slag, iron bearing dust, NM450 plate impact resistance steel mill scale, environmental protection dust has reached 100%.

BBN Group's first blast furnace blast dehumidification system: The project started construction on May 2 and began trial operation on August 28. All data are balanced and stable, blast furnace output indicators have improved significantly, and the daily dehydration capacity of the two blast furnaces is as high as 124 tons, with a daily increase of about 200 tons NM450 plate impact resistance, and the blast furnace is running smoothly.

Boiler steel plate mainly refers to the hot-rolled medium and thick plate materials used to manufacture superheater, main steam pipe and heating surface of boiler fire chamber. The commonly used NM450 plate impact resistance, boiler steel is low carbon killed steel smelted in open furnace or low carbon steel smelted in electric furnace, with carbon content in the range of 0.16% - 0.26%.

Relying on the background of high-quality steel resources and its own strong steel machining capabilities, BBN comany can not only supply various steel material products, such as steel coils, steel plates, NM450 plate impact resistance sheet, steel pipes, and shaped steels, but also provide a variety of steel deep processing services like cutting, welding and grinding. Through continuous technological innovation and after-sales service optimization, the company has its own world on the domestic and international steel industry stage!
