A kind of preparation method of stainless steel slag water seepage expansion cooling column

Abstract

The present invention involves a preparation method of a stainless steel slag seepage and expansion and cooling column. The cooling column is based on lime stones, with water glass as a bonding agent, sodium sodium siliconate, and sodium tritetum phosphate as a hydrophobic agent.Fragmentation, mixing, mixing, cold solid of the mold, vibration molding, and milling of the raw materials are made to make a strong seepage of water inflation and cooling column. Use the same material to make a positioning board, supporting grid board, and the cooling column, positioning board, supporting grid boardThe inlaid device is in the stainless steel dregs tank. After spraying water and cooling, it penetrates into the bottom and surroundings of the residue tank after absorbing, so that the steel slag is fully absorbed, exuded, expands, cools down, and is safe and reliable.The technical cooling efficiency is high and the cooling effect is good. It is an ideal cooling treatment technology of stainless steel residue. This technology can also be used for cooling treatment of other steel slag.

Description

technical field [0001] The invention relates to a preparation method of a stainless steel slag seepage expansion cooling column, which belongs to the technical field of steelmaking waste slag cooling treatment and application. Background technique [0002] Steel slag is the waste slag in the process of steelmaking. It is a solid waste, accounting for about 12-15% of steel production. It is used as an auxiliary material for smelting flux, building aggregate, cement and fertilizer. [0003] The temperature of steelmaking is very high and must be higher than the melting point of the metal. Stainless steel is a special steel containing chromium, nickel, manganese, molybdenum, copper, silicon and other elements. It is lower than the smelting temperature, and its temperature value is 1500°C. Before the steel slag is processed, the stainless steel slag must be cooled before it can be reused industrially. Due to the high temperature and large quantity of stainless steel slag, rapi...

Problems solved by technology

[0004]Currently, the cooling treatment technology of steel slag is still at a relatively low level, for example: the cold disposal method, steel slag is poured into the slag tank for slow cooling and then transported directly to the slag yard Abandoning, polluting the environment, is not conducive to comprehensive utilization; hot stewing method, digging pits to bury slag, spraying water to cool, and subsequent slag screening is cumbersome; hot splashing method, slope dumping, water cooling, land occupation is large; Spray water on the slag tray, but the treatment capacity is small, occupying a lot of water, and the cost is high; there are also open-air water quenching methods, stewed slag water quenching methods, shallow pan water quenching methods, etc., but the water is too much and it is easy to accumulate water, polluting the surrounding environment Seriously, the wet method occupies a large area and consumes water, the dry method is slow, and the processing cost is high. There are some technical deficiencies, and they are not ideal.
