Efficient recarburization accelerant

Abstract

The invention provides an efficient recarburization accelerant. The efficient recarburization accelerant is characterized in that the efficient recarburization accelerant is composed of metal powder,a carbon material and a binding agent. The binding agent is composed of an organic binder body and an inorganic binder body. The inorganic binder body is at least one of orthosilicic acid, silicate and clay. The organic binder body comprises the following components of, by weight, 10-16 parts of sodium carboxymethylcellulose, 10-16 parts of cellulose acetate butyrate, 0.5-3 parts of starch, 1-3 parts of poval, 2-5 parts of borax and 3-6 parts of paraffin. The efficient recarburization accelerant is wide in application, can be used for recarburization in the smelting process of carbon steel, plain carbon steel, alloy steel, special steel, gray pig iron, nodular cast iron and the like, synergistic effects occur among the components, the absorption rate of recarburization can be sharply improved, the particle sizes are even, the quality is stable, using is convenient, no flying dust is generated, safety and environmental protection are achieved, and the recarburization effect is excellent.

Description

technical field [0001] The invention relates to a high-efficiency carburizing accelerator. Background technique [0002] In the steelmaking production process, it is necessary to add carbon to the molten steel in the ladle to meet the carbon content requirements of various specifications of steel, so some special carburizers are needed. The existing types of recarburizer include pig iron, forged coal recarburizer, coke powder recarburizer, coke recarburizer, pitch coke recarburizer, graphite electrode recarburizer, petroleum coke recarburizer, carbon powder core These existing carburizers have many defects, such as many types of impurities, high impurity content, relatively low fixed carbon content, and relatively high water content. The recarburizer has defects such as poor melting during the steelmaking carburization process, unsatisfactory carbon absorption rate or carbon recovery rate, or high price and complicated preparation process.
