Q345RZ35 Vessel plate thickness direction performance and Wugang production and supply
1, Q345RZ35 steel plate introduction:
Q345R is a common grade of boiler and pressure vessel steel plate, Q345RZ35 is the steel plate with additional thickness direction performance Z35.
2. Q345RZ35 container board implementation standard: GB/T713-2014.
3. Q345RZ35 the size, shape, weight and allowable deviation of the steel plate a, the size, shape and allowable deviation of the steel plate shall comply with the provisions
of GB/T709 b, the thickness deviation of the steel plate shall meet the requirements of GB/T709 class B deviation, according to the requirements of the buyer, it can also be delivered according to the class C deviation
of GB/T709 c, and the steel plate shall be delivered
according to the theoretical weight. The density of the steel plate used for the calculation is 7.85t/m³.
3. Q345RZ35 steel plate delivery status: hot rolling, controlled rolling, normalizing.
a. Normalizing: After heating above the phase change temperature, it will be cooled normally (in air).
b. Controlled rolling: By controlling the process parameters such as heating temperature, rolling temperature, and deformation system, the change law of austenite structure and the microstructure of phase transformation products are controlled, so as to achieve the purpose of refining the structure and improving the strength and toughness.
