Abstract

The invention discloses a solid metal calcium and magnesium-rare earth alloy composite core-spun cable. An outer layer of the core-spun cable is a 0.3-0.5-millimeter-thick ordinary steel belt; a core layer comprises a rare earth-magnesium alloy powder layer, a middle protection layer and a solid core metal calcium wire; the solid core metal calcium wire is wrapped by the middle protection layer; the middle protection layer is wrapped by the rare earth-magnesium alloy powder layer; the mass ratio of the solid core metal calcium wire to the rare earth-magnesium alloy powder layer is 1:(2-5); and the particle size of rare earth-magnesium alloy powder is smaller than 3 mm. The alloy powder is added into micro-alloyed steel by adopting a core-spun cable method, so that the treatment process of calcium and magnesium is stable, and high absorptivity is achieved; and current problems are well solved. Besides, storage time is longer; yield is more stable; and the solid metal calcium and magnesium-rare earth alloy composite core-spun cable has remarkable economic benefits.

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...
