Main business: carbon steel plate cutting, round steel cutting, stainless steel cutting, round pipe cutting, A588 grade A heavy plate, steel structure welding. It can also cut various machine tool side plates, special-shaped parts, flanges, bearing seats, bearing supporting bases, embedded parts, counterweights, rolling stands, cutting squares, cutting circles, etc. according to customer drawings. BBNsteel company has good business channels with major steel mills, and undertakes all kinds of steel plate processing services.
Our company has A588 grade A heavy plate strong technical force, complete production equipment, advanced production technology, perfect testing methods, and high quality. It has a Class D (Class I and Class II pressure vessel) manufacturing license, and has passed the China Beijing Quality Center GB/T19001-2000 -ISO9001: 2000 quality certification. We can also supply A588 grade A heavy plate deep processing service for products A588 grade A heavy plate like cutting, drilling, bending, welding and grinding.
The hot rolling method is to heat the A588 grade A heavy plate steel material to about 1000 ℃ ~ 1250 ℃ and use the rolling mill to roll it. The traditional hot rolling process is generally divided into the following two steps: the first step is to use the primary rolling mill or billet rolling mill to roll the ingot, billet or continuous casting billet into a certain shape and size of billet. This kind of A588 grade A heavy plate rolling process is usually called semi-finished product production, also called blank production.
Temperature has a great influence on the strength of the material, A588 grade A heavy plate. When the temperature exceeds a certain value, the strength limit of the steel will be reduced. The higher the temperature, the lower the strength. In addition, the longer the steel is used at high temperature, the lower the strength. Therefore, if the steel works at high temperature for a long time, the instantaneous strength of the steel can not be used as its performance index, nor can the room temperature performance replace the high temperature performance.
Our company will accept the product quality objection registration record, pass it to the A588 grade A heavy plate production unit and relevant departments, and timely coordinate the supervision of product A588 grade A heavy plate quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
