Embodiment 1

[0056] A cooling method for stainless steel slag, comprising the steps of:

[0057] (1) After the stainless steel slag from the steel plant is finished, pour it into 11m 3 The slag tank, the slag tank containing stainless steel slag was continuously transported to the dumping area of ​​the slag yard by train, and a total of 8 tanks of steel slag were poured into the pool;

[0058] (2) Use the W1002 type electric crane to break the hard shell formed on the surface of the steel slag, so as to avoid the steel slag falling down as a whole when it is tipped over, which will cause the liquid slag to splash and hurt people;

[0059] (3) Connect the tilting device on the pot stand to the power supply, start the device to make the slag pot tip over, and cooperate with the pot pounder to beat the edge of the pot to pour all the steel slag in the pot into the storage space, and then use the gun hammer to break the large pieces of steel slag. Visually check that there is no steel slag la...

Abstract

The invention discloses a method for cooling stainless steel slag, which comprises the steps as follows: (1) a step of preparing steel slag: after deslagging, the stainless steel slag is shifted to a stainless steel processing station, the steel slag is broken to pieces below 500 mm, and the steel slag is poured into a hot braised pool; (2), a step of open water-cooling: spray interval water-cooling is performed on the steel slag in the hot braised pool in step (1); and (3), a step of hot braised water-cooling: closed water-cooling is performed on the steel slag after the step (2), and hot braise and cooling are performed until total water consumption amount of steel slag per ton ranges from 0.4 ton to 0.6 ton. The method for cooling the stainless steel slag shortens the cooling processing period of the stainless steel slag, restrains dust raising pollution in a dusting cooling process, and reduces purchasing quantity of slag pots and places occupied by cooling.

Description

technical field [0001] The invention relates to the field of metallurgy, in particular to the technical field of processing stainless steel red slag. Background technique [0002] Steel slag is a major companion in the production process of iron and steel enterprises. Due to the entrainment of metals, steel slag treatment is an indispensable and important process in the production process of iron and steel enterprises. [0003] The steel slag must be cooled before being processed. Due to the variety of steel slag produced in the stainless steel production process, the composition and properties are different, and it has the characteristics of high alkalinity and easy pulverization during the cooling process. The dust pollution during the cooling process belongs to the iron and steel field. problem. Traditional cooling methods are mainly hot splash method and cooling method with canned water. Although the hot-splashing method can effectively cool down the steel slag, the du...
