BBN STEEL exported S690QL quenched and tempered material to Mongolia

The advantages of S690QL quenched and tempered material, medium and thick boiling steel plate: The surface is relatively smooth, the quality is good, and it is easy to process. Because medium and thick boiling steel plate does not have concentrated shrinkage holes, the amount of deoxidizer is small, and boiling steel plate price is lower than other steel plates. Disadvantages of medium and thick boiling steel plate: it has a lot of gas content and impurities, it is not easy to weld, and its bearing capacity is worse than other steel plates, so it is not suitable for parts that need to bear gravity.

Low welding crack sensitivity high-strength steel plate, today mainly introduces Q620CF, with three grades C, D, E. The grades of low-welding crack sensitivity high-strength steel plate: Q460CFC, Q460CFD, Q460CFE, Q500CFC, Q500CFD, Q500CFE, Q550CFC, Q550CFD , Q550CFE, Q620CFC, Q620CFD, Q620CFE, Q690CFC, Q690CFD, Q690CFE, S690QL quenched and tempered material, Q800CFE. It is mainly used for the production of hydropower penstocks, construction machinery, railway vehicles, bridges, high-rise and large-span buildings that require high weldability.

S690QL quenched and tempered material, Hot-rolled steel coils are made of steel billets, which are made into strip steel by the rough rolling mill and the finishing mill after heating. The hr steel strip from the rolling mill behind the finishing rolling is cooled to a set temperature by laminar flow, and then coiled into a steel coil by the coiler. The cooled steel coil will undergo different processes according to the different needs of users, and is processed into steel plates, flat coils and slit steel strip products.

During the steel plate cutting, the special-shaped steel plate cutting process is often carried out. In this operation process, some cutting curves will be generated. Therefore, there should be relatively high precision standards during the processing of S690QL quenched and tempered material. The operators need to have rich experience, and they also need to be proficient in the operation methods and working skills of the equipment, so as to ensure that the steel plate can meet the shape requirements after processing.
