Technical key points for the production of S690QL steel welding

The BBNSTEEL company has the first-class qualification for steel structure professional contracting, integrating production, design and installation, and can undertake various steel structure projects. The product has a wide surface, flat and smooth surface, and neat trimming. It has users in more than 10 provinces and cities in China and is exported to the United States, Canada, Japan, Europe, Southeast Asia and other countries and regions.

The main applications of S690QL steel welding, wear plates: 1. Mining machinery and equipment. 2. Construction machinery and equipment, such as excavators, shovel, sand making machines, etc.. 3. Laying on the ground, wear-resistant plates will be laid on the roads of some construction sites. 4. Construction equipment, excavation machinery, earth moving machinery, compaction machinery, engineering lifting machinery, piling machinery, etc. are all in contact with various kinds of sediment for a long time, and need the support of wear-resistant plates. There are also many equipment that runs repeatedly and frequently, and wear plates are needed.

Ordinary carbon structural steel S690QL steel welding has many impurities and low price. The ordinary carbon structural steel is used in places with low performance requirements and low strength, but it has good plasticity, toughness and cold deformation performance. High quality carbon structural steel has less harmful impurities, and its strength, plasticity and toughness are better than those of ordinary carbon structural steel. High quality carbon structural steel is mainly used to manufacture important mechanical parts.

Weathering steel generally adopts the process route of fine material into the furnace-smelting (converter, electric furnace-microalloying treatment-argon blowing-LF refining-low superheat continuous casting (feeding rare earth wire)-controlled rolling and cooling. The scrap steel is added into the furnace together with the charge, and smelted according to the conventional process. After the S690QL steel welding steel is tapped, deoxidizers and alloys are added. After the molten steel is treated with argon blowing, the molten steel is cast. By adding rare earth elements to the steel, the S690QL steel welding weathering steel is purified and the content of inclusions is greatly reduced.
