For boiler equipment, in addition to a certain hardness, it also needs a boiler vessel plate with good compressive capacity, so as not to affect the normal use of boiler equipment due to large pressure in use.
The production of boiler and vessel plate is not so simple. After the production, there are also some processing links to process the equipment, which helps to improve the performance of boiler and vessel plate. Let's learn about the production process of boiler vessel plate.
If the type and amount of deoxidizer are controlled to make a certain amount of oxygen remain in the steel, when enough strong oxidants are added to make the steel deoxidize well, the co bubbles will escape during the solidification process and generate boiling phenomenon. When the steel solidifies, there will be no co bubbles, and the steel remains calm is called killed steel. The steel used for boiler vessel plate is killed steel, which is called boiling steel. The steelmaking furnace can only be used as primary refining, and the refining needs to be completed in the refining equipment outside the furnace.
External refining is also called secondary refining. It is mainly through decarburization, desulfurization, denitrification and dephosphorization to improve the cleanness of boiler vessel plate, establish the technology of chromium molybdenum low alloy steel with good oxidation resistance and high temperature strength, remove unwanted harmful impurities from boiler vessel plate, and improve the internal quality of boiler vessel plate. Chromium molybdenum steel is one of the commonly used steel for boiler vessel plate. It is widely used in oil refining, chemical hydrogenation units and hydrogen treatment equipment in reforming units. Therefore, on the basis of common carbon steel, Cr, Mo, V and other alloy elements are added. It has excellent hydrogen corrosion resistance and good high temperature strength. It is the material of high temperature and high pressure vessel shell and head.
In the processing of boiler vessel plate, it is different from ordinary steel plate, so some elements need to be added to improve the performance of steel plate. In fact, for different boiler vessel plate, their materials are also different, so as to better adapt to the use of different boilers. BBN provides a variety of types of boiler vessel plate with reliable quality. No matter in the production or processing of boiler vessel plate, it has strict quality and technical inspection, which is a good choice for you.
