Q370qC steel plate implementation standards

Q370qC expression: Q370qC steel plate is a kind of bridge steel with high strength, high toughness and corrosion resistance. In the name of this steel, "Q" represents the first letter of the Chinese pinyin of "Qu" in bridge steel, "370" represents the yield point value in MPa, and "q" represents the Chinese pinyin of "bridge" in bridge steel. The first letter of Pinyin, "C" represents the quality level of C level.

Q370qC steel plate smelting process:

The Q370qC steel plate is smelted in a 150t top-bottom double-blown converter, using a weak deoxidation process. The LF-RH refining process reduces the refining requirements for the converter tapping temperature and reduces converter point blowing. At the same time, low superheat pouring is used to obtain continuous casting slabs with good surface and internal quality. The upper limit of the casting speed is strictly limited, constant speed pouring, and fully protected pouring are used to reduce contamination of molten steel during the pouring process.

Outstanding features of Q370qC steel plate:

Q370qC steel plate has good corrosion resistance and uses special anti-corrosion treatment technology to effectively resist chemical corrosion and atmospheric corrosion. This characteristic allows the steel plate to maintain its structural and performance stability for a long time under harsh environmental conditions.

Q370qC steel development and prospects:

Q370qC steel plate has wide application prospects in the field of bridge construction due to its excellent properties such as high strength, high toughness and corrosion resistance.

Q370qC steel plates are mainly used to make road bridges and railway bridges (including cross-sea bridges) with riveted and bolted structures, which can meet the construction needs of large bridges. Its high strength and toughness enable the bridge to withstand larger loads and improve the safety and durability of the bridge. At the same time, this kind of steel has also been widely used in cold areas, which can effectively prevent bridges from brittle fracture in cold environments and extend the service life of bridges.
