Definitions
- the invention relates to a method and a processing system for treating high temperature solid steel slag. Background technique
- Steel slag is an inevitable by-product of the steelmaking process, accounting for about 10% to 15% of steel production. Therefore, the rapid and effective treatment of steel slag, especially high-temperature steel slag, directly affects the normal operation of the steelmaking process and the sustainable development of steel companies. Due to the differences in steelmaking processes in different steel mills, the composition and temperature of the steel slag produced during the smelting process are not the same: some high-temperature steel slags have good fluidity and can pour like water; some have poor fluidity and are difficult to remove from slag.
- the tank (container that holds and transports high-temperature steel slag, also known as the slag pack) is conveniently poured out, and must be poured out of the slag pot by means of mechanical external force or by inverting the slag pot.
- the existing hot steel slag treatment process is typically hot, wind quenched, shallow pan, hot stuffing, drum process and so on.
- Hot pouring is a relatively primitive treatment process.
- the high-temperature steel slag is poured on a designated site.
- the heat of the steel slag is lost by air cooling or spraying a small amount of water.
- it is necessary to continuously use the excavator or The forklift is turned over; the hot-treated steel slag can not be directly used, and it needs to be piled up for several months and then crushed and sorted again for users to use.
- the whole process is not only long in process, large in area, but also in harsh operating environment and serious pollution, and there is a tendency to be replaced by other processes.
- the air quenching process represented by the disclosures of JP24238276 and CN88211276 better realizes the rapid granulation treatment of liquid steel slag.
- the quenched slag has fine and uniform particle size and stable performance, and can be directly utilized.
- the disadvantage is that the processing object of the process is strictly limited, and only the steel slag with good fluidity can be treated, and the steel slag with high viscosity and poor fluidity cannot be treated.
- the shallow-disc steel slag treatment process improves the production efficiency on the basis of the hot-spraying process, but there are still shortcomings such as long treatment cycle, high pollution, high operating cost, and aging of steel slag.
- the hot slag hot slag process represented by CN02157162.7 and CN200410096981.0 realizes the rapid pulverization treatment of steel slag. After about 12 hours, the steel slag of about 800 °C is pulverized into millimeters by the thermal stress and chemical stress of the steel slag itself.
- the fine slag powder of the grade can be directly used as clinker for cement production after sorting.
- the process is relatively simple and can also achieve full quantitative treatment of steel slag; but the shortcomings are also very obvious: In view of safety considerations, the process can only process block steel slag below 800 °C, high temperature steel slag must be hot first Cooling outside the pool, during the period to improve production efficiency, it is inevitable to repeatedly turn over, dust and heat pollution is serious.
- the roller slag treatment process represented by CN99127012.6 and CN200410054165.3 has realized the concept of rapid treatment of high-temperature steel slag in a closed container for the first time. It can be rotated around a closed container within 1500 °C within a few minutes.
- the high-temperature liquid slag is dynamically, continuously and rapidly cooled and broken into granular commercial slags below 100 ° C for direct use by users.
- the large amount of dust-containing vapor generated during the treatment process is discharged by the chimney after being purified, which eliminates the drawbacks of steam and dust flying in the traditional slag treatment process.
- the treatment of high-viscosity slag caused by the slag splashing furnace can also be realized by means of a dedicated skimmer.
- the disadvantage is that the existing drum unit cannot achieve the cleaning treatment of the bottom slag. Due to the large degree of slag at the bottom of the tank and the lack of fluidity, it cannot be directly poured into the existing drum unit. It also needs to be equipped with a special slag slag yard to dump the bottom slag and some of the high slag remaining in the slag residue. The field is traditionally cooled and broken, so the efficiency is affected and dust is generated.
- Another object of the present invention is to provide a treatment system for high temperature solid steel slag to achieve high efficiency treatment of high temperature steel slag.
- the main idea of the invention is to carry out the slag into the high-temperature solid steel slag and gradually process it in the closed container, and the processing device is the feeding cylinder and the working cylinder double-chamber series drum, thereby realizing the cleaning and high-efficiency treatment of the high-temperature steel slag. .
