| titleOfInvention | A Method for Manufacturing Continuously Cast Strands from Bi-S Free-Cutting Steel |
| abstract | The present invention relates to a method for producing a cast steel of Bi-S free-cutting steel, the object of which is to add the appropriate amount of boron to the steel during the production of the cast steel of Bi-S free-cutting steel, and to control the casting speed, Bi-S free-cutting steel that minimizes, reduces pin hole and blow hole in cast state, improves center segregation, and reduces surface burst in billet state. It is to provide a method for manufacturing a cast.n n n The present invention for achieving the above object by weight, carbon: 0.036-0.084%, silicon: 0.5% or less, manganese: 1.20-1.40%, phosphorus: 0.07-0.09%, sulfur: 0.270-0.330%, bismuth: 0.08 Using Bi-S free cutting steel containing -0.16%, nitrogen: 70 ppm or less, boron: 80-150 ppm, remaining Fe and other unavoidable impurities, the F [O] (free oxygen concentration) in the tundish is 25-100 ppm The present invention relates to a method for producing a cast steel piece of bismuth-sulfur free-cutting steel, which is controlled so as to perform continuous casting at a casting speed of 0.60-0.70 m / min. |
