| titleOfInvention | The chrome molybdenum series circular pipe blank slab quality control method of φ 280mm |
| abstract | Disclosed by the invention is a kind of internal quality control method for producing the chrome molybdenum series pipe steel strand that cross dimensions is φ 280mm of field of metallurgy.This method includes converter smelting, LF stove refined molten steels, RH is refined and continuous casting steel, first, in the smelting molten steel stage according to rational state modulator, improve the degree of purity of molten steel, and by carrying out Trace Titanium Treatment to molten steel, improve its high-temp plastic, reduce steel grade crack sensitivity, then during pouring molten steel, using M-EMS in a manner that solidification end electromagnetic agitation is combined, so that molten steel component and equalizing temperature, green shell homoepitaxial, casting blank solidification tissue is effectively improved, loose grading improves, equiax crystal region area expands, round billet central area compactness effectively improves, strand crack defect is effectively controlled, surface is improved improvement without cleaning rate, mill bar quality control is good and stablizes. |
