Embodiment Construction

[0010] The refractory clay containing vanadium iron slag according to the present invention will be described in detail below with reference to exemplary embodiments.

[0011] The refractory clay according to the present invention contains fine aggregate and a gel material formed from fine powder of vanadium iron slag. Specifically, the refractory clay according to the present invention contains 50%-80% by weight of fine aggregate and 20%-50% by weight of a gel material formed from vanadium iron slag fine powder.

[0012] Here, the vanadium iron slag contains 78% to 83% by weight of Al 2 O 3 , 10%-17% CaO, 1.0%-2.5% MgO, 0.2%-0.8% FeO, 0.6%-0.8% SiO 2 and 1.3% to 4.0% of vanadium oxide. The vanadium iron slag contains 35% to 40% of calcium aluminate phase, 45% to 55% of monocalcium dialuminate phase, 4% to 7% of α-Al by volume percentage 2 O 3 phase, 7% to 8% of vitreous phase, 1% to 3% of metallic phase and 3% to 5% of spinel phase.

Abstract

The invention discloses fireproof fire clay with vanadium iron slag. The fireproof fire clay contains fine aggregate and gel material formed by vanadium iron slag fine powder. The fireproof fire clay with vanadium iron slag has excellent performance; and by adopting the fireproof fire clay, the overall performance and service life of the brick lining refractory material can be increased.

Description

technical field [0001] The invention relates to a refractory material, in particular to a refractory mud. Background technique [0002] In recent years, with the rapid development of metallurgical industry, the demand and consumption of refractory materials are increasing. However, the resources available for refractory materials are becoming less and less, so scientific and technological personnel have been working on the development of secondary resources that can be used for refractory materials. [0003] In addition, a large amount of ferrovanadium slag will be produced in the process of smelting ferrovanadium. At present, there is no good method for utilizing ferrovanadium slag, which leads to the accumulation of a large amount of ferrovanadium and causes environmental pollution. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to overcome the above-mentioned and / or other deficiencies, and provide a kind of refractory mud containing vanadium...
