Abstract

PURPOSE:To utilize slag effectively for aggregate for construction work after seasoning the converter slag utilizing a vegetable cultivation plant and washing the seasoned slag discharged from the plant. CONSTITUTION:The slag discharged from a converter plant 12 is crushed to grain size suitable to the earth for a vegetable cultivation plant 14 by a crusher 13. The crushed slag is laid evenly for a cultivating bed of the vegetable cultivation plant 14. Caustic lime in the crushed slag reacts with sprayed water to form slaked lime and the slag is seasoned. After seasoning is completed, the slag is discharged and washed by a washing device 15 to remove roots of the vegetables or impurities such as fertilizer, to provide aggregate 16. By this process, seasoning is performed completely in a short time, and slag is converted to stabilized aggregate.

The slag lump discharged from the converter contains granular quicklime in a dispersed state. Therefore, there is water in the slag mass.
Then, the quicklime contained reacts with water and becomes slaked lime, which expands and breaks up the slag mass. The slag discharged from the converter has the property of expanding and collapsing.

Hot metal produced in a blast furnace (shown in the diagram) is injected into a converter (1), and pure oxygen is blown into it from an oxygen injection lance (0]).
(hereinafter referred to as blowing) to decarburize and produce steel. At this time, the converter (

A large amount of slag floats on the surface of the hot metal poured into the tank. On the other hand, during blowing, pure oxygen and carbon in the hot metal combine to generate a large amount of CO gas.

First, in the initial stage of blowing, outside air is sucked in from the gap between the converter (11) and the cooler (2) (hood), and CO gas is combusted to produce a CO gas layer. (2)
Since the space between the holder and the holder (6) is filled with outside air,
This is to prevent the cooled CO gas from reacting with the above-mentioned filled outside air and causing an explosion.

That is, the CO gas is isolated from the outside air while being sandwiched between the Co gas layer and the CO gas layer, and is recovered while being prevented from exploding. The above CO gas layer is usually called a tampon gas layer. This tampon gas layer is dissipated into the atmosphere from the exhaust tower (5) by switching the damper (7). In this way, a large amount of heat and a large amount of CO and gas are obtained from the converter factory.

Now, in the past, the large amount of slag discharged from converter factories amounted to to-ioθkg per ton of crude steel produced.
In order to season them, they were piled up on a large site and exposed to the natural wind and rain. However, it takes 6 months to 1 year to perform seasoning, and the RM balance between the amount of slag discharged from the converter factory and the seasoning cannot be maintained, and the slag continues to accumulate. Furthermore, even if the material is seasoned for several months to a year, it cannot be guaranteed to be perfect, and there is a technical problem in that it is unreliable as a construction aggregate.
