Abstract

This invention discloses sodium silicate-iron ore powder semiconductor block charging for producing steel in electric furnace. The block charging is poor conductor under normal conditions, and is process-oriented good conductor in working state in electric furnace by cooperation of sodium (with initial conductive effect) and silicon (with resistance at inverse ratio with temperature). The block charging is used for producing high-quality iron or steel in electric furnace. With the block charging, the previous oxidation method of iron production is replaced by one-time energy conversion. The electromagnetic production method has electrofusion effect only on metals, and has such advantages as no electrically synthetic substance generation, little generation and discharge of oxides, high efficiency, low energy consumption and little pollution.

Description

1. Technical field: [0001] The charge belongs to the category of metallurgy, and the charge provides direct raw materials for melting iron and steel in electric furnaces. 2. Technical background: [0002] 1. Today's iron and steel production methods [0003] Today's iron production is an oxidation production method fueled by coal, which produces and emits a large amount of oxides, causing major harm to the earth's ecological environment and life and health. Nowadays, electric furnace steelmaking only uses pig iron, scrap iron and steel and ferroalloy as furnace materials (with a small amount of high-grade massive iron ore as furnace materials), and electric furnace steelmaking is a multiple fuel energy configuration. Iron and steel production is still in the primary production mode stage of high energy consumption, high pollution, and high cost (huge investment in hot blast stoves, repeated energy consumption in electric furnaces).
