Hot rolled hardox 400 welding carbon structural
Our company's HARDOX 400 welding 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 HARDOX 400 welding utilization rate of secondary energy and realize negative energy steelmaking in steelmaking process.
The selection principle of steel plate for high-rise building is: it can not only make the structure safe and reliable, but also can save steel and reduce the cost. Different use conditions should have different quality requirements. In terms of the mechanical properties of steel such as HARDOX 400 welding, yield point, tensile strength, elongation, cold bending property, impact toughness etc. are the indicators to measure the quality of steel. In the design of steel structure, the appropriate steel should be selected according to the characteristics of the structure. The selection of steel is not only an economic problem, but also related to the safety and service life of the structure.
