PVQ P295GH boiler steel plate,Focusing on the energy conservation and emission reduction objectives proposed by the municipal government, the company gives full play to the advantages of circular economy formed after the comprehensive completion and operation, and vigorously promotes the implementation of energy conservation objectives Through measures such as energy saving, technological innovation and management strengthening, the energy saving target of annual reduction of added value energy consumption by 7% It has made great contribution to energy saving of over completion,PVQ P295GH boiler steel plate.

PVQ P295GH boiler steel plate,17MN4 steel plate, , DIN 17135 17MN4 steel plate is a kind of material for boiler and pressure vessel steel. DIN 17135 17MN4 steel plate is characterized by a minimum yield strength of 220 - 295 MPa and by good weldability, so 17MN4 steel is mainly used for manufacturing boilers, pressure vessels and pipes transporting hot liquids.

Difference between Q345R boiler vessel plate and ordinary Q345 plate, :Q345R boiler vessel plate is pressure vessel steel, Q345 plate is low alloy steel.Q345R boiler vessel plate generally requires flaw detection and positive deviation, while Q345 plate generally has lower requirements.In terms of performance, Q345R boiler vessel plate and Q345 plate are of the same level. However, due to high requirements, they can not be mixed in general.Generally, the requirement of Q345R boiler vessel plate is higher than Q345 plate, PVQ P295GH boiler steel plate.

PVQ P295GH boiler steel plate,In the second step of hot rolling process, different finished mills are used to roll billets or continuous casting billets into finished steel of proper shape and size. This production process is called finished product production, which is generally divided into two stages of rough rolling and finish rolling. In the roughing stage, a large amount of reduction (reduction per pass) is adopted to reduce the number of passes and improve the output; after roughing, the finishing stage is entered, and the finishing is carried out with a small amount of reduction to achieve a good surface and accurate size.
