Our company's normalized CCS grade E bulk vessels steel power boilers, heating furnaces of double bars, double high lines and medium and thick plates all adopt heat storage technology, which can fully use blast furnace gas; the ladle baking, Maerz active lime kiln and medium and thick plate heat treatment furnace all burn converter gas, which can improve the normalized CCS grade E bulk vessels steel utilization rate of secondary energy and realize negative energy steelmaking in steelmaking process.
CortenB vs 45#: Corten B medium-carbon quenched and tempered steel has higher strength, toughness and hardenability than 45# steel. Corten B steel can obtain better comprehensive mechanical properties after quenching and tempering. The cutting performance is still good, but the welding performance is poor, the cold deformation plasticity is low, and the temper brittleness tendency. It is generally used in quenched and tempered state, and can also be used in quenched, tempered or normalized state.
Q215 steel has good plasticity and weldability. Q235 steel has certain strength, plasticity, toughness and weldability. Q235 steel is easy to punch and can meet the use of steel structure. Q255 steel has high strength, good plasticity and weldability, and its application is not as extensive as Q235 steel. Q275 steel has high strength, poor plasticity and weldability. Q275 steel is used for shafts, connecting rods, gears, keys and metal components with high strength requirements.
The cold bending method is mainly used to produce cold-formed section steel and welded pipe. The cold bending method is to bend the steel strip or steel plate into various cross-section shapes by the cold bending machine in the cold state. If the normalized CCS grade E bulk vessels steel steel pipe is bent into a circular, square or other hollow shape and welded by a proper welding method, it is a welded pipe. The advantages of cold bending: first, the cold-formed section steel is light in weight and large in bearing capacity, and it can save metal by replacing the hot-rolled section steel; second, it can produce all kinds of normalized CCS grade E bulk vessels steel extremely thin, extremely wide and complex section steel which can not be produced by hot rolling.
How much is plate normalized CCS grade E bulk vessels steel per ton? FOB Shanghai: 635$/ton q345qd steel is steel for highway bridges, which is a thick steel plate specially used for erecting railway lines or road and highway bridges. It is required to have high compressive strength, ductility and bearing the load and impact of railway vehicles, as well as excellent fatigue relief, certain ultra-low temperature ductility and air corrosion resistance.
First of all, we should establish a correct concept of after-sales service. Service concept is an important part of corporate culture and a long-term enterprise value concept. Our company's after-sales service embodies the concept of "customer first, sincere service for customers". As long as we are in the "sincere service for users" under the guidance of the idea, I believe we will get rich returns.
