Problems solved by technology

The aluminate cementitious material produced by this method requires a high calcination temperature, so the energy consumption is large and the production cost is high
However, the use of ferrovanadium waste slag to produce aluminate cementitious materials is rarely reported.

Embodiment 1

[0023] Air-cool the 50% ferrovanadium ferrovanadium waste slag just out of the furnace to normal temperature, weigh 10kg, crush it with a jaw crusher, and then crush it with a disc crusher to a size below 3mm, and then grind the crushed slag in a roller ball mill. Use a 0.045mm square hole sieve to sieve the ferrovanadium waste slag to no more than 20% to obtain the aluminate cementitious material. .

Embodiment 2

[0025] Air-cool the 80% ferrovanadium ferrovanadium waste slag just out of the furnace to normal temperature, weigh 15kg, crush it with a jaw crusher, and then crush it with a disc crusher to a size below 3mm, add 0.5kg of gypsum, and mix it in the Grinding in a roller mill, and using a 0.045mm square hole sieve, the residue does not exceed 20%, and then the aluminate gelling material can be obtained.

Embodiment 3

[0027] Air-cool 50% ferrovanadium ferrovanadium waste slag just out of the furnace to normal temperature, weigh 13kg, crush it with a jaw crusher, and then crush it with a disc crusher to a size below 3mm, add 1kg of gypsum, mix it evenly, and put it on the drum Grinding in a ball mill, and using a 0.045mm square hole sieve, the residue does not exceed 20%, and then the aluminate gelling material can be obtained.

Abstract

The invention provides a preparation method for producing aluminate gelled material by ferro vanadium waste, which is characterized in that, after the discharged hot ferro vanadium waste is cooled by wind, the ferro vanadium waste is smashed and milled into powder, wherein the fineness is required to meet the requirement that not more than 20 percent of screen residue is left after going through a 0.045mm square mesh sieve; and then the aluminate gelled material is obtained. The aluminate gelled material is characterized by high fire resistance degree, high compressive strength and rupture strength, good corrosion resistance, etc., which can be widely applied to amorphous refractory products.

Description

technical field [0001] The invention relates to the technical field of aluminate cementitious material preparation, in particular to a preparation method for producing aluminate cementitious material by utilizing vanadium-iron waste slag. Background technique [0002] High vanadium iron, especially 50 vanadium iron or 80 vanadium iron, is a very important alloy additive in steel. At present, the main process for producing ferrovanadium is the aluminothermic reduction method. During the production process of the aluminothermic reduction method, a large amount of ferrovanadium waste slag, also called corundum slag, will be produced. In China, only Panzhihua Iron and Steel produces more than 5,000 tons of ferrovanadium waste slag every year. Now after capacity expansion, the annual output will exceed 10,000 tons. The current utilization method of ferrovanadium waste slag is to further extract the residual vanadium in the ferrovanadium waste slag, so that the residual vanadiu...
