Abstract

The invention discloses a carbon-iron alloy for vacuum induction furnace smelting testing steel recarburization and a manufacture method thereof, and belongs to the technical field of ferrous metallurgy. The carbon-iron alloy is manufactured by raw materials including high-carbon steel scrap, graphite blocks, SiCa alloy and auxiliary materials. The raw materials are prepared and weighted according to requirements of weight percentage. Firstly, the graphite blocks and the high-carbon steel scrap are placed inside a vacuum intermediate frequency induction furnace crucible to be melted in a vacuum mode. When silicon barium calcium is completely deoxidized, the auxiliary materials and the SiCa alloy which are prepared and weighted according to the requirements of the weight percentage are added into liquid steel inside the crucible. After the SiCa alloy and the auxiliary materials are melted and mixed evenly, the liquid steel is poured into an ingot mold to be completely cooled. After mold sinking and demolding, the carbon-iron alloy ingot is formed. The carbon-iron alloy ingot is quenched and is cut into a carbon-iron alloy block with the size of 10mm*10mm*50mm-300mm through a saw, and the carbon-iron alloy block is used for the vacuum induction furnace smelting testing steel recarburization.

Description

1. Technical field [0001] The invention belongs to the technical field of iron and steel metallurgy, and in particular relates to a carbon-iron alloy used for carburizing experimental steel in vacuum induction furnace smelting and a manufacturing method thereof. 2. Background technology [0002] my country is the largest steel producing country in the world, but there is still a considerable gap between the variety and quality of steel products and the advanced level of foreign countries, and a considerable amount of steel products still needs to be imported. [0003] In the modern steel product research and development process, the research and development personnel expect to replace tens of tons of steel billets with samples weighing hundreds of kilograms, tens of kilograms, or even tens of kilograms. The platform conducts new product research and development, and conducts smelting and rolling pilot experiments simulating industrial conditions with small samples under stri...
