Focusing on the energy conservation and emission reduction objectives proposed by the municipal government, the company gives full play to the advantages of A514 grade P QT steel plate 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 A514 grade P QT steel plate 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.
12CrMoV pressure vessel steel is a kind of pearlite heat-resistant steel, which has high structural stability and thermal strength when used for a long time at high temperature. It has low overheating sensitivity during heat treatment and no tendency of temper brittleness; A514 grade P QT steel plate steel has high plasticity and machinability during cold deformation.
Because A514 grade P QT steel plate, boiler steel plate is a product of important use, the safety and reliability requirements are strict, and the manufacturing technology is difficult. The boiler steel plate material must have the following main characteristics:The boiler steel plate has high yield strength performance in a certain temperature range (medium temperature and high temperature);The boiler steel plate has sufficient toughness, no brittle failure accident will occur during manufacturing or use.
The fake and inferior A514 grade P QT steel plate, steel plates have no metallic luster and are light red or similar to pig iron for two reasons. 1. Its blank is adobe. 2. The rolling temperature of counterfeit and inferior materials is not standard, and their steel temperature is visually inspected. In this way, rolling cannot be carried out in the specified austenite area, and the performance of the steel plate will naturally not meet the standard.
