preparation example Construction

[0041] The invention provides a method for preparing titanium-alloyed molten steel, which comprises: feeding the titanium-magnesium composite cored wire described in the invention into molten steel to be titanium-alloyed for titanium alloying.

[0042] According to the preparation method of the present invention, preferably, the molten steel to be alloyed with titanium is molten steel that has been alloyed with carbon, silicon and manganese, and the temperature of the molten steel to be alloyed with titanium is 1550-1600°C.

[0043] According to the preparation method of the present invention, in order to facilitate the rapid feeding of the cored wire into molten steel, and at the same time in order to improve the yield strength and tensile strength of the titanium alloy steel, titanium alloying is preferably carried out under dynamic conditions. Shaking or turning can be realized, for example, the steel ladle can be shaken while the cored wire is fed into the molten steel in t...

Abstract

The invention provides a titanium-magnesium composite core-spun yarn which comprises a core layer and an outer layer wrapped outside the core layer, wherein the core layer contains titanium-iron powder and magnesium powder. The invention provides application of the titanium-magnesium composite core-spun yarn in preparing titanium alloying molten steel. The invention provides a preparation method of the titanium alloying molten steel, which comprises the following steps: feeding the titanium-magnesium composite core-spun yarn into molten steel to be subjected to titanium alloying, and carrying out titanium alloying. The invention provides a titanium alloying molten steel prepared by the method. The invention provides a titanium-containing alloy steel which is prepared by casting the titanium alloying molten steel. In the preferable embodiment, the core-spun yarn is used for implementing titanium alloying of molten steel, and the titanium recovery rate is high and stable (80-85%), thereby effectively enhancing the quality of the molten steel.

Description

technical field [0001] The invention relates to a titanium-magnesium composite cored wire and its application in titanium alloying of molten steel, a titanium alloyed molten steel and a preparation method thereof, and a titanium-containing alloy steel. Background technique [0002] In order to ensure the various physical and chemical properties of steel, it is necessary to add alloy additives to the steel to adjust its composition to the specified range. Elements (C, Si, Mn, S or P) that are not present in ordinary steel or have a small content are all alloying elements. Alloy additives can be pure materials (nickel, copper, aluminum, graphite powder, etc.), ferroalloys (ferromanganese, ferrosilicon, ferrovanadium, ferrotitanium, etc.), or compounds of alloying elements (oxides, carbides, etc.) substances, nitrides, etc.). [0003] Ni, Mo, Cu, Co and other elements have low affinity with oxygen, so they can be added together with the charge or during the smelting process; ...
