Nano-material interalloy modifier and preparation method thereof, and alloy preparation method

Abstract

The present invention relates to a nano-material interalloy modifier and a preparation method thereof, and an alloy preparation method. The nano-material interalloy modifier comprises the following components, by mass, 5-15% of nano-powder, 1-3% of magnesium powder, 30-40% of sodium potassium ore powder, 40-50% of iron powder, 3-8% of hydroxypropyl cellulose, and 2-4% of water. The nano-material interalloy modifier is not easily oxidized and polymerized during processes of mixing and preparation, has a sufficient strength, is not easily decomposed during using and transportation, and can be rapidly molten when the nano-material interalloy modifier is added to a liquid steel, hot iron, or a nonferrous alloy liquid.

Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to the technical field of iron and steel and non-ferrous metal alloys, and specifically relates to a nanomaterial master alloy modification agent, a preparation method and an alloy preparation method. Background technique [0002] At present, with the continuous increase of my country's steel production, the problems of high energy consumption and high pollution are becoming more and more serious. Facing this trend, how to improve the performance of steel on the basis of maintaining the existing steel production has become a The direction of current industry research. [0003] In order to improve the performance and strength of metal materials, all countries have carried out the development of a new generation of steel. At present, the ultra-fine grain steel developed at home and abroad has the characteristics of high strength, corrosion resistance, and weldability, but the produc...

Problems solved by technology

But its disadvantages are: nano-materials are easy to float on the surface of steel liquid and mixed with steel slag, the addition amount is difficult to control, and the argon blowing pressure and injection process are not easy to master; The loss of the argon tube is large, which increases the production cost

Because the nanomaterials are very small and have a large surface area, the specific gravity is also very light, but after the nanomaterials are simply mixed, bonded and pressed into products, when this mixed material is added to the steel liquid, it will easily float on the surface. The surface of the liquid will lose its effect when mixed with slag. At the same time, too much nanomaterial addition will not only fail to crystallize to the core and strengthen dispersion, but will cause harmful effects such as slag inclusion in the liquid steel.

In addition, during the heating and pressing process of powder metallurgy, nanomaterials are easily oxidized and polymerized and lose their inherent properties.
