Rolling of steel plates is the core of the entire steel rolling production process. The billet is deformed by rolling. The rolling process plays a decisive role in product quality. The quality requirements of rolled A709 grade HPS50W bridge steel plate products include the three aspects of product geometry and dimensional accuracy, internal organization and performance, and product finish. Finishing: It is the last process in the A709 grade HPS50W bridge steel plate rolling process, and it is also a more complicated process. It plays a final role in guaranteeing the quality of the product.
If a destructive accident occurs during the use of the boiler, it will cause serious losses. Therefore, other than some common strengths with A709 grade HPS50W bridge steel plate, the boiler steel plate must have good physical properties, mechanical properties and workability, and be strictly specified in the technical terms of the material standard to meet its safety in use. High temperature (above creep temperature) boiler steel plates are generally low-alloy heat-resistant steels, such as chromium molybdenum steel, chromium molybdenum vanadium steel, chromium molybdenum tungsten steel, etc.
