Embodiment Construction

[0010] Exemplary embodiments according to the present invention will be described in detail below.

[0011] The refractory castable according to the present invention is mainly formed of coarse aggregate, fine aggregate and a binder formed of fine powder of ferrovanadium slag.

[0012] The ferrovanadium slag used in the present invention comprises 78%~83% Al by weight percentage 2 o 3 , 10% to 17% of CaO, 1.0% to 2.5% of MgO, 0.2% to 0.8% of FeO, 0.6% to 0.8% of SiO 2 And 1.3% to 4.0% of vanadium oxide. In addition, ferrovanadium slag is mainly composed of 35% to 40% calcium aluminate phase, 45% to 55% monocalcium dialuminate phase, 4% to 7% α-Al 2 o 3 phase, 7%-8% glassy phase, 1%-3% metal phase and 3%-5% spinel phase.

[0013] Coarse aggregate, fine aggregate and binder will be described in detail below.

[0014] The refractory castable according to the present invention comprises 30%-50% of coarse aggregate, 20%-40% of fine aggregate and 10%-30% of binder formed of va...

Abstract

The invention provides a refractory castable material containing ferrovanadium dregs. The refractory castable material containing the ferrovanadium dregs comprises coarse aggregate, fine aggregate and a bonding agent formed by fine powder of the ferrovanadium dregs. The refractory castable material has excellent fireproof performance. A great amount of ferrovanadium dregs can be recycled.

Description

technical field [0001] The invention relates to a refractory castable, in particular to a refractory castable containing ferrovanadium slag. Background technique [0002] At present, with the rapid development of my country's metallurgical industry, the consumption of refractory materials is increasing, but the resources available for refractory materials are relatively small. Therefore, scientific and technical personnel have been working hard to develop resources that can be used as refractory materials. [0003] In addition, when using vanadium-titanium magnetite to smelt ferrovanadium, a large amount of ferrovanadium slag will be produced. A large amount of ferrovanadium slag is piled up and cannot be recycled, which not only causes environmental pollution, but also causes waste of resources. Contents of the invention [0004] The object of the present invention is to overcome the above and / or other deficiencies, and provide a novel refractory castable containing fer...
