preparation example Construction

[0026] Correspondingly, the present invention also provides a preparation method of the above vanadium extracting coolant, the preparation method comprising the following steps: 40-82 parts by weight of vanadium extraction and dedusting ash, 12-52 parts of iron oxide scale and 6-8 1 part of binder is mixed for batching; mix the prepared material, add water while mixing, the weight ratio of water to material is 3:50~5:50; briquetting the mixed material, pressing The vanadium-extracting coolant is obtained after the good block is dried. Among them, the proportion of each component in the vanadium extraction coolant is mainly set in consideration of the cooling effect and the use effect, because the particle size of the vanadium extraction dust removal ash is small, if the proportion of the vanadium extraction dust removal ash is too much or too little, it will affect the cost. Block rate, and the proportion of iron oxide scale must also be appropriate, otherwise the TFe content ...

Embodiment 1

[0032] Mix 5 tons of vanadium-extracting primary dedusting ash, vanadium-extracting secondary dedusting ash, hot-rolled iron oxide scale, and binder in a mass ratio of 32:50:12:6, and mix them in a mixer. During the stirring process, evenly add 300kg Water, after stirring evenly, the raw materials are sent to the briquetting machine for pressing, and the raw materials that are not agglomerated are returned to the briquetting machine hopper, and the pressed wet material blocks are transported by a chain grate machine, and are dried with hot air at 200°C during the transport process. The finished product of vanadium extraction coolant has a one-time block rate of 93%, uniform shape, good strength, and will not break when dropped from a height of 2m; among them, the content of TFe is 61.39%, the content of P is 0.067%, the content of S is 0.06%, and the content of The water content is 1.8%, which fully meets the requirement of being used as a coolant for vanadium extraction.

Embodiment 2

[0034] Mix 10 tons of vanadium-extracting primary dedusting ash, vanadium-extracting secondary dedusting ash, hot-rolled iron scale, and binder in a mass ratio of 10:30:52:8, and mix them in a mixer. During the stirring process, evenly add 600kg Water, after stirring evenly, the raw materials are sent to the briquetting machine for pressing, and the raw materials that are not agglomerated are returned to the briquetting machine hopper, and the pressed wet material blocks are transported by a chain grate machine, and are dried with hot air at 200°C during the transport process. The finished product of vanadium extraction coolant has a one-time block rate of 92.4%, uniform shape, good strength, and will not break when dropped from a height of 2m; among them, the content of TFe is 60.00%, the content of P is 0.071%, the content of S is 0.08%, and the content of The water content is 2.2%, fully meeting the requirement of being used as a coolant for vanadium extraction.

Abstract

The invention discloses a vanadium extraction cooling agent, which comprises the following components in percentage by weight: 40-82 percent of vanadium extraction dust removing ash, 12-52 percent of oxide iron scale and 6-8 percent of binding agent. The invention also discloses a preparation method of the vanadium extraction cooling agent. The preparation method comprises the following steps of: proportioning 40-82 percent of vanadium extraction dust removing ash, 12-52 percent of oxide iron scale and 6-8 percent of binding agent by weight; mixing the proportioned materials; adding water while mixing, wherein the mass ratio of the water to the materials is 3:50-5:50; briquetting the uniformly mixed materials; and drying the pressed blocks to obtain the vanadium extraction cooling agent. According to the vanadium extraction cooling agent and the preparation method thereof, the one-time block forming rate of the vanadium extraction cooling agent is over 92 percent, the TFe content reaches over 60 percent, less P, S, water and the like are included, the requirements on use as the vanadium extraction cooling agent are fully met, the dust removing ash produced by the vanadium extraction of a converter can be completely and effectively utilized, the cost is saved, the requirements on vanadium extraction production of the converter can be completely met, and the maximum utilization of a vanadium resource is facilitated.

Description

technical field [0001] The invention relates to a coolant for vanadium extraction in a converter and a preparation method thereof, more specifically, to a vanadium extraction coolant and a preparation method thereof using vanadium extraction and dust removal ash as a raw material. Background technique [0002] my country is a big country of vanadium-titanium magnetite. Compared with ordinary molten iron, the molten iron smelted from vanadium-titanium magnetite has higher vanadium content, and vanadium is an important resource. Therefore, it is necessary to extract vanadium and make Take the vanadium slag. At present, there are many production methods for producing vanadium slag at home and abroad, mainly including the ladle blowing vanadium process in New Zealand, the vanadium extraction process in South Africa, and the converter vanadium extraction process in Russia and China. Other vanadium extraction processes include vanadium-containing steel slag extraction process. Van...
