Abstract

The invention relates to a preparation method of an HRB500E niobium-containing titanium alloy deformed steel bar, and relates to the technical field of alloy steel. The preparation method comprises the following steps: step a, controlling, by a central control module, a molten iron pouring device to add a preset volume of molten iron into a converter; step b, adding waste steel, a niobium-titanium alloy and quick lime into the converter; step c, carrying out first-time converter smelting to generate molten steel; step d, carrying out first detection on the molten steel generated by the first smelting; step e, adding the molten iron into the converter, carrying out secondary smelting, and carrying out secondary detection on molten steel obtained after secondary smelting is completed; step f, controlling, by the central control module, the molten iron pouring device to add the molten iron into the converter for third-time smelting, and detecting the molten steel obtained after third-time smelting for the third time; and step g, carrying out argon blowing, continuous casting, rolling and heat treatment sequentially on the molten steel with the carbon content meeting the requirement after third-time detection. According to the method, the quality of the produced deformed steel bar is effectively improved.

Description

Technical field [0001] The present invention relates to the technical field of alloy steel, and more particularly to a method of preparing a HRB500E containing biothenium-containing titanium alloy. Background technique [0002] Threaded steel is a commonly known as hot rolled ribbon steel bar, and the normal hot rolled steel brands are composed of HRB and grades of yield points. [0003] At present, the alloy strengthening is achieved during the production of HRB500 threaded steel, but the vanadium alloy is a shortage of resources in my country, and the price has been in a high level and has risen sharply with the implementation of the new national standard. However, titanium alloy can replace vanadium alloy Implement alloy enhancements, and my country's titanium resources, mature production technology, and market prices have long stable. [0004] Carbon is a non-metallic element, which is an indispensable component of steelmaking. It is the element that is contained in steel. Th...
