Hot rolled what is Q355GNH steel manufacturer

After heating, a billet is refined for several passes of rolling, then edge cutting and straightening to become a what is Q355GNH steel steel plate, which is called hot rolling. Due to its high strength, good toughness, easy processing, good weldability and other excellent properties, hot rolled steel plate products are widely used in shipbuilding, automobile, bridge, construction, machinery, pressure vessel and other manufacturing industries.

What is what is Q355GNH steel, boiler steel consumption rate? The cost of the boiler, to a large extent, depends on the steel consumption of the boiler. The so-called boiler steel consumption rate refers to the tons of boiler steel used per 1t / h evaporation capacity of the boiler, also known as the boiler steel consumption per unit evaporation. The boiler steel consumption rate of boilers with different parameters, capacities and structures is different.

Advantages of hot rolling: hot rolling can destroy the casting structure of ingot, refine the grain of steel and eliminate the defects of microstructure, so that the steel structure is dense and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that the what is Q355GNH steel steel is no longer isotropic to some extent; the bubbles, cracks and looseness formed during pouring can also be welded under the action of high temperature and pressure.

The company attaches great importance to the cultivation of team spirit. Personal strength is weak. After sales service departments, leaders and subordinates often communicate with each other. Everyone often holds meetings to discuss their problems in after-sales service, discuss technical difficulties, discuss how to improve work efficiency, how to better deal with user complaints, etc.
