This technology, unlike conventional gas, does not require the use of explosive cylinders. Unlike laser-plasma welding constructions can be done without even machining and thus receive a good quality of the edges, which naturally lowers the cost of production. Machining. When you want to cut small amounts of special steel, and no significant quality requirements for nesting, are still using mechanical cutting. For her, as a rule, standard power tools – Circulation Saw, Bulgarian, shears, rotating grinding wheels and more. Circulation saw used for cutting profiled metal small size. With it you can get even a qualitative slice with minimal tolerances.
For special steel sheet is usually applied cutting (cutting) the guillotine. This is a fairly accurate view of cutting. Methods to improve the quality of steel processing to improve the properties of steels for special purposes, you can use modern technology of rolling. So, on the line DeadFlat (correcting rolling) finished sheets are processed in the cold state. This process allows you to remove the residual stress of the metal and improve its junction characteristics: the reduction of surface roughness and increase its flatness. DeadFlat lines in the world yet limited: one of them is installed at the factory in Finland. Several years ago, the company invested 20 million euros in the construction service metal center (SMC) in St. Petersburg, where implemented almost all the most popular operations with steel.
Late last year, has launched a new line in the smc cross cutting fagor, allowing cut material to a working thickness of 3 mm (this is at 1,5 mm more than in used previously), the maximum width of the sheets -1600 mm (today – 1250 mm) maximum sheet length – 6000 mm (at today’s 2500 mm). On the line is set Unwinder to 16 tons (the maximum weight a roll today -12 tons). Modern equipment smc allows you to produce a final product that can withstand all the European standards. So, on the cutting line is set in 1921 right spindle, so that the flatness of sheets twice the requirements of standards din. The line is fully automated and equipped with modern means of control, so the operator can at any moment to make adjustments in the manufacturing process. Steel for special purposes – rather demanded product, even in times of crisis and decline in production volumes. Obviously, the quality of the products of such a rental should be provided with modern productive technologies. Only such an approach would economically and efficiently handle the valuable material and give a real competitive advantage in the difficult economic situation.
