| titleOfInvention | METHOD FOR PRODUCING A FORMATABLE AUTOMATIC STEEL WITH DEFINED FUELS |
| abstract | The invention relates to a method for producing a convertible free-cutting steel with a defined structure, which combines good formability with good machining properties. It is the object of the invention to produce a deformable free-cutting steel of defined structure which is capable of discharging both the material-economically unfavorable Al and Si-killed automatic insertion machine steels as well as the working productivity in the machining of formed parts compared to conventional machining Increase construction dysfunctions. The essence of the invention is that a molten steel after refining has an active oxygen content of 600 to 850 ppm at a temperature of 1943 to 1973 K, which after addition of at most 24 kg of ferromanganese, 2.5 kg of sulfur, 0, 4 kg of ferroboron and 1.0 kg of a low-calcium silicon alloy per ton of steel and inert gas flushing is set to at most 100 ppm. After heating at a rate of 200 to 500 K / h, holding at 1 613 to 1 653 K, the crude steel is rolled at a temperature of 1 373 to 1 443 K. |
