Technology for producing building material from vanadium-titanium technology blast furnace dry slag

Abstract

The invention relates to the technical field of blast furnace dry slag, and discloses a technology for producing a building material from vanadium-titanium technology blast furnace dry slag. The technology comprises the following steps: 1) collecting the blast furnace slag generated in a furnace body by using a professional device, placing the collected blast furnace slag in a processing device bya conveying machine, processing the blast furnace through a hot splashing process by using the processing device, and carrying out air cooling treatment on the processed blast furnace slag; and 2) maximally processing dry slag by using an existing slag bath, controlling the formation of the crystalline phase microstructure of slag blocks to make the dry slag reach the strength of different ores,rapidly solidifying the blast furnace slag by using a water spraying process until the blast furnace slag is cooled in order to make the blast furnace slag meet transshipment conditions, and filling atransporting device with the cooled and solidified blast furnace slag. The technology for producing the building material from vanadium-titanium technology blast furnace dry slag can produce constructional slag broken stone and slag sands, and can massively and comprehensively utilize the blast furnace slag to solve the present situation of waste stockpiling.

Description

technical field [0001] The invention relates to the technical field of blast furnace dry slag, in particular to the technical research on the production of building materials from blast furnace dry slag of vanadium-titanium technology. Background technique [0002] Vanadium is known as "the monosodium glutamate of modern industry". It is widely used in the fields of steel, chemical industry and aerospace. It is a rare metal with a wide range of uses. It is understood that vanadium is mainly used in alloys to improve the properties of steel [0003] At present, the domestic blast furnace slag smelted by ordinary mines is basically used in industries such as cement and slag powder, and is basically not stockpiled. The high-titanium blast furnace slag smelted by vanadium-titanium ore is very low in activity, and its comprehensive utilization is severely limited. According to the current annual 5 million tons of iron will be produced, and the annual output of blast furnace slag...
