Multicomponent adjuvant for combustion

Abstract

The invention relates to multicomponent adjuvant for combustion, which comprises the following constituents (by weight portions): industrial sodium carbonate 40-360, industrial sodium carbonate 40-400 parts, industrial sodium sulphate 5-30 parts, industrial boric acid 5-30 parts, industrial barium sulphate 5-50 parts, industrial ammonium fluoride 1-10 parts, industrial aluminun fluoride 1-10 parts, these constituents are dissolved into 900-1100 parts of water having temperature of 20-65 deg C to obtain the liquid state multicomponent burnt adjuvant.

Description

Technical field: [0001] The invention relates to a multi-element sintering aid, in particular to a multi-element sintering aid which can be blended with middle and low-grade aluminum-containing ores to sinter calcium aluminate, and belongs to the field of inorganic non-metallic materials in the metallurgical industry. Background technique: [0002] In my country's bauxite resources or waste resources, low- and medium-grade aluminum-containing ores such as high-silicon, high-iron, low-aluminum or low-aluminum-silicon ratio tailings, abandoned ore, industrial solid waste such as fly ash, slag, coal gangue, Bauxite, kyanite, andalusite, sillimanite, nepheline, kappa nepheline, muscovite, leucite, albite, analcite, sericite, kaolinite, alunite, etc., among these resources AL 2 o 3 The bauxite content is only 15-50%, which accounts for a considerable proportion in our country, and these resources have not been fully utilized so far. The development and utilization of such low-gra...

[0002] In my country's bauxite resources or waste resources, low- and medium-grade aluminum-containing ores such as high-silicon, high-iron, low-aluminum or low-aluminum-silicon ratio tailings, abandoned ore, industrial solid waste such as fly ash, slag, coal gangue, Bauxite, kyanite, andalusite, sillimanite, nepheline, kappa nepheline, muscovite, leucite, albite, analcite, sericite, kaolinite, alunite, etc., among these resources AL 2 o 3 The bauxite content is only 15-50%, which accounts for a considerable proportion in our country, and these resources have not been fully utilized so far. The development and utilization of such low-grade bauxite resources has important social significance for the rational use of national resources. Economic and practical significance; on the other hand, with the development of my country's industry, the demand for bauxite has increased sharply, making the supply of bauxite increasingly tight, especially the supply of high-quality bauxite will not be able to meet the needs of alumina or hydrogen. The need for alumina production has caused the production cost of alumina and aluminum hydroxide to rise, and ore resources have become more and more restrictive factors for the development of the aluminum industry
