Patent attributes
Disclosed is a method for using cold rolling magnetic filtration waste, comprising using the cold rolling magnetic filtration waste as a fluxing agent for a high-ash-fusion coal so as to achieve the technical requirements of a high melting point coal in dry coal powder gasification and liquid slagging. The cold rolling magnetic filtration waste contains solid particulates with very fine particles (iron-containing particles mainly produced by friction), and the surface thereof has a cold rolling oil attached thereto, and same reacts with other aluminosilicates in coal ash at a high temperature to produce low temperature eutectic compounds such as fayalite (Fe2SiO4) and hercynite (Fe2Al2O4). The fluxing agent has characteristics such as having fine particles, being free of inorganic mineral substances, having an effective ingredient in a high content, operation thereof being simple, and being free of pollution.
