Abstract

The invention provides special steel used for manufacturing an environment-friendly dustproof bag cage to meet the requirement for steel of the environment-friendly dustproof bag cage and also provides a production process used for manufacturing the environment-friendly dustproof bag cage. The special steel comprises, by mass, 90.5%-95.5% of scrap steel, 1.35%-2.65% of pig iron, 0.82%-1.85% of nickel, 1.43%-2.85% of chromium, 0.25%-0.52% of molybdenum, 0.58%-1.55% of manganese and 0.07%-0.21% of silicon. The high-performance dustproof bag cage can be obtained through the special steel.

Description

technical field [0001] The invention relates to the field of special-purpose steel preparation, in particular to a special steel for making an environment-friendly dust removal bag cage and a preparation method thereof. Background technique [0002] Electric arc furnace steelmaking is a steelmaking method that uses electric energy as the heat source and scrap steel as the main raw material. Relying on the electric arc generated by the discharge between the electrode and the charge, the electric energy is converted into heat energy, and the metal charge is heated and melted by the direct action of the arc radiation and the arc, and smelted into steel. Electric arc furnace steelmaking is one of the most advanced steelmaking technologies at present. It can smelt steels with strict requirements on mechanical properties and chemical composition. Through the adjustment of formula technology, it can fully meet the needs of smelting steels for environmental protection dust removal b...
