Abstract

The invention relates to an alloy powder cored wire, in particular to a composite cored wire of solid metal calcium and magnesium-rare earth alloy containing various elements. An outer layer of the cored wire is an ordinary steel strip with a thickness of 0.3-0.5 millimeter; a core layer comprises a rare-earth magnesium alloy powder layer, an intermediate protective layer and a solid metal calcium wire; the solid metal calcium wire is wrapped with the intermediate protective layer; the rare-earth magnesium alloy powder layer wraps the intermediate protective layer; the mass ratio of the solid metal calcium wire to the rare-earth magnesium alloy powder layer is 1:(2-5); the particle size of the rare-earth magnesium alloy powder layer is less than or equal to 3 mm. Calcium and magnesium processing processes can be stabilized through adding into micro-alloyed steel by adopting a cored wire method, and the higher absorption rate is obtained, so that the currently-confronted problem is better solved. The storage time is longer, the yield is more stable, and the economic benefits are significant.

Description

technical field [0001] The invention relates to an alloy powder cored wire. Background technique [0002] my country's steel industry is at its peak in history. In the next few years, it is estimated that my country's annual steel output will reach 1.8 billion tons, and the cored wire market will reach more than 5 billion yuan. According to the statistics of the World Iron and Steel Association, in 2011, the total steel output of all countries in the world reached 1.6 billion tons, an increase of 15%; while China ranked first in the world with an output of 700 million tons. In addition, with the continuous advancement of science and technology, various projects Structural design tends to be high-parameter, lightweight and large-scale. The performance of steel materials requires higher strength and better toughness. Core-spun wire feeding processing technology plays an indispensable and important role in this. [0003] Obtaining products with higher purity and higher uniform...
