Abstract

The invention relates to a preparation method of HRB500E niobium-titanium alloy threaded steel, and relates to the technical field of alloy steel. Add scrap steel, niobium-titanium alloy and quicklime; step c, carry out first converter smelting and generate molten steel; step d, first detect the molten steel generated by first smelting; step e, add molten iron to the converter, and carry out second smelting, The molten steel that has been smelted for the second time is detected for the second time; in step f, the central control module controls the molten iron pouring device to add molten iron to the converter, and the third smelting is performed. Carry out the third detection; step g, sequentially perform argon blowing, continuous casting, rolling and heat treatment on the molten steel whose carbon content meets the requirements after the third detection. The method of the invention effectively improves the quality of the rebar produced.

Description

technical field [0001] The invention relates to the technical field of alloy steel, in particular to a preparation method of HRB500E niobium-titanium alloy threaded steel. Background technique [0002] Rebar is a common name for hot-rolled ribbed steel bar. The grade of ordinary hot-rolled steel bar is composed of HRB and the minimum yield point of the grade. [0003] At present, the HRB500 rebar is produced by adding vanadium alloy to achieve alloy strengthening, but vanadium alloy is a scarce resource in my country, and the price has been at a high level and has risen sharply with the implementation of the new national standard. However, titanium-niobium alloy can replace vanadium alloy. Alloy strengthening is achieved, and my country is rich in titanium resources, mature in production technology, and stable in market prices for a long time. [0004] Carbon is a non-metallic element and an indispensable component of steelmaking. It is an element that coexists with iron dur...
