Embodiment 1

[0044] For 70kg of sintered material, add calcium permanganate aqueous solution (calcium permanganate 350g, the mass percentage of water is 7.5%±0.2% of the mass of the mixture) in two parts, the first mixing time is 4min, and the second mixing time is 4min. After mixing evenly, ignite for 2 minutes. The ignition temperature is 1050±50°C. When the exhaust gas temperature reaches the maximum value and starts to decrease after sintering, stop sintering to obtain sintered ore.

Embodiment 2

[0046] For 70kg of sintered material, add calcium permanganate aqueous solution (calcium permanganate 700g, the mass percentage of water is 7.5%±0.2% of the mass of the mixture) in two times, wherein the first mixing time is 4min, and the second mixing time is 4min. After mixing evenly, ignite for 2 minutes. The ignition temperature is 1050±50°C. When the exhaust gas temperature reaches the maximum value and starts to decrease after sintering, stop sintering to obtain sintered ore.

Abstract

The invention belongs to the field of metal smelting, and particularly relates to a sintering method for sea sand vanadium-titanium-iron concentrate. The technical problems that the sea sand vanadium-titanium-iron concentrate belongs to high titanium type schreyerite, the sintering performance is poor, the yield of sinter, the utilization coefficient and indexes like the drum index are poor compared with indexes of common ore are solved. According to the scheme, the sintering method of the sea sand vanadium-titanium-iron concentrate comprises the following steps that firstly, in the even mixing process before sintering, a calcium manganate aqueous solution is added into the sinter, and a mixture is prepared; and b, ignition is carried out, the mixture is sintered to obtain the sinter. The method is easy and convenient to operate, practical and suitable for industrialized production.

Description

technical field [0001] The invention belongs to the field of metal smelting, and in particular relates to a sintering method of sea sand vanadium-titanium iron concentrate. Background technique [0002] Sea sand vanadium-titanium iron ore concentrate belongs to high-titanium vanadium-titanium ore, which has poor sintering performance, and its sintered ore yield, utilization coefficient, drum index and other indicators are worse than ordinary ore. [0003] At present, the sintering cup method is commonly used. The experimental conditions are as follows: the amount of sintered new material is 70kg, and water is mixed in two times. The first mixing time is 4 minutes, and the second mixing time is 4 minutes. The mass percentage of water in the mixture is 7.5% ± 0.2 %; When sintering, the thickness of the material layer is 700mm, the ignition time is 2min, and the ignition temperature is 1050±50°C. [0004] The experimental steps of the sintering cup are: 1) Weigh the materials ...
