The controlled cooling process of Q390D carbon steel plate sheet

Steel production and rolling technology and equipment also pursue the continuity between processes, such as the continuous Q390D carbon steel plate sheet process between continuous casting and rolling mills, continuous casting slabs hot transfer hot charging, increased direct rolling, and continuous cold rolling processes. The development of controlled rolling and controlled cooling technology that combines rolling and heat treatment has played a huge role in improving the properties of rolled materials.12Cr1MoV alloy plate is widely used in superheater, header and main steam pipe of high pressure, ultra-high pressure and subcritical power plant boiler. At 580 ℃, 12Cr1MoV alloy plate still has high thermal strength, oxidation resistance and high endurance plasticity. The production process of Q390D carbon steel plate sheet and 12Cr1MoV alloy plate is simple and the welding performance is good, but it is sensitive to the normalizing cooling rate Pearlite spheroidization will occur after long-term use of 12Cr1MoV alloy plate at 580 ℃,Q390D carbon steel plate sheet.In the final analysis, the market competition is the competition for customers Whether selling products or services, the final customer satisfaction is the standard to test the success or failure of marketing work The so-called after-sales service is to fully understand customers, study customer psychology, pay attention to after-sales details, improve work shortcomings, improve service quality, and Exchange customer brand loyalty through the whole process of quality service,Q390D carbon steel plate sheet.Q390D carbon steel plate sheet,Over the years, the company has strived for perfection, being well-received.
