Abstract

A method for producing steel used in a titanium master alloy bonding wire by small billet continuous casting belongs to the steelmaking technical field. The process route is as follows: low-sulfur molten iron and scrap steel, converter blowing, slag blocking and tapping, steel ladle deoxidation alloying, secondary refining, complete protection continuous casting by a small billet caster and casting blank inspection. The method is characterized by controlling technical parameters of critical process links, reducing the contents of aluminum and nitrogen in the molten steel, solving the problem of submerged nozzle clogging and crystallizer protecting slag floater easily occurring at the small billet continuous casting of high titanium steel variety, and realizing the smooth production of thesteel used in the titanium master alloy bonding wire by the small billet continuous casting. The method has the advantages of being capable of replacing a production process for producing the steel used in the titanium master alloy bonding wire by continuous casting of die casting and large billets, achieving 0.08-0.17% titanium content of a product and fully meeting the use requirement of the steel used in the bonding wire.

Description

technical field

[0001] The invention belongs to the technical field of steelmaking, and in particular provides a production method of billet continuous casting high-titanium alloy welding wire steel; it is specially used in the production of a type of high-titanium high-strength alloy welding wire steel, which can replace mold Casting and bloom continuous casting production methods. Background technique

[0002] So far, the development of welding technology has been aimed at high energy efficiency and high efficiency. As far as welding materials are concerned, high energy efficiency includes welding materials that can achieve high deposition and high speed, welding materials with excellent all-position weldability, etc.; high efficiency includes welding materials that can omit post-processing processes by reducing spatter, etc. . Welding materials have been developed from electrodes to submerged arc welding wires, and then to solid cored wires and flux cored wires. At pre...
