Embodiment

[0011] Take the production of a 120-ton converter and a 250m³ blast furnace as an example:

[0012] 1. The output of each furnace of the converter is 120 tons of steel, the amount of steel slag is 100 kg / ton of steel, and the steel slag produced by each furnace is 12 tons. Converter steel slag is poured into hot stuffy slag pool by slag irrigation;

[0013] 2. According to the standard of balancing 5% free calcium oxide, haul 600 kg of ironmaking slag from the blast furnace to the hot stuffy slag plant;

[0014] 3. Directly use the loader to pour 600 kg of ironmaking slag into the hot stuffy slag pool filled with converter slag, and use the excavator to stir normally, but this process omits the conventional water cooling process, and uses the heat energy of the steel slag to promote the slag and smelting process. Iron slag undergoes slagging reaction;

[0015] 4. After the temperature of the steel slag in the hot stuffy slag pool is reduced to 300-900°C, it is processed acco...

Abstract

The invention discloses a steel slag modification process for producing materials for a road water stabilizing layer. After ironmaking water-quenched slag is subjected to iron separation on a magnetic separation line, the ironmaking water-quenched slag obtained after iron separation is added into a pyrolytic slag pond containing liquid converter slag, the adding amount of the ironmaking water-quenched slag accounts for 3%-7% of the amount of the liquid converter slag, and then converter steel slag to which the ironmaking slag is added is mechanically stirred to be uniform through a conventional pyrolysis process; in the process, a conventional water fetching cooling process is omitted, conventional pyrolysis is carried out after the steel slag is cooled to 300-900 DEG C, pyrolytic slag particles are magnetically separated after pyrolysis is completed, and the magnetically-separated pyrolytic slag particles are directly used as the materials for the road water stabilizing layer.

Description

technical field [0001] The invention relates to a steel slag modification process for producing materials for road water stabilization layers. Background technique [0002] In the iron-making production project, every ton of iron produced produces 200-400 kg of iron-making slag and 80-150 kg of steel-making slag. Iron-making slag is a medium-acid substance, rich in many vitreous phases, low in strength and insufficient in hardness, and cannot be directly used as road materials. Its main lithofacies structure is dicalcium silicate, calcium aluminum feldspar, magnesium Huang feldspar, etc.; steelmaking slag is a mineral structure dominated by high-alkalinity silicate structure, with more free calcium oxide, and the main lithofacies structure in steel slag is also in the process of transformation from tricalcium silicate to dicalcium silicate. Free calcium oxide precipitates out. Although high-basic converter steel slag can be used in road construction, it needs aging treatme...
