Abstract

The invention discloses a technological method of disposing iron making slag without water. The technological process lies in that the slag fused during iron making is first led into the heat preserving furnace, cushioned, tempered, and put into a mould for cooling, and then the slag is cut and made into standard slag bricks or slag plates. With the special technological process of disposing the slag without water, the invention can greatly save water, reduce necessary large equipments, reduce the manufacturing cost, and the produced building materials and products have heat preserving, sound-absorbing and energy saving functions.

Description

A kind of processing method of disposing iron making slag without water
Technical field: the processing method that the present invention relates to a kind of disposing iron making slag without water.
Background technology: along with the fast development of industry, various novel process for smelting novel methods also enter fast-developing track.But present traditional blast furnace slag treatment process, employed or old treatment process.The main component of blast furnace slag is Calucium Silicate powder Cosio 3, proportion is 2.2-2.5 gram/cubic centimetre when liquid, proportion is 2.3-2.7 gram/cubic centimetre during solid, every kilogram of heat content 400-460 kilocalorie.Temperature is at 1400 ℃-1550 ℃, mostly adopts water quenching during former processing slag, and water loss is huge, and the slag utility value is low, and needs large-scale flushing cinder and overhead traveling crane marine salvage equipment, should not store, and has increased production cost.
Summary of the invention: the present invention has changed the drawback that former blast furnace slag treatment process exists, and provides slag utility value height, the processing method of a kind of disposing iron making slag without water that reduces production costs.Its processing method is earlier slag fused during iron making to be imported in the holding furnace, cushion with modified after, put into pattern and cool off, cut then, make the cinder brick or the slag plate of standard.Because the present invention has adopted the special process method of no water treatment slag, utilization of waste material meets the recycling economy that country promotes, and the building material made of producing has insulation, sound insulation and energy-conservation effect.Its concrete advantage is: 1, water not, can alleviate the water pressure of using of iron work greatly, and significantly reduce production costs.
2, can cancel flushing cinder, processing apparatus such as overhead traveling crane salvaging have reduced facility investment.
3, improved the added value of slag, slag is appreciated for per ton more than 100 yuan by original 20-30 per ton unit, and enterprise profit is risen.
4, multi-usage, because in cinder brick and the slag plate numerous apertures is arranged, especially the goods of handling through foaming have the effect of insulation, sound insulation, can be applicable to body of wall, roof and tabernacular dividing plate.
5, this project investment is little, has reduced environmental pollution, can replace existing clay brick and concrete brick, meets the water saving of country's popularization and the policy of recycling economy.
Embodiment: its processing method is earlier slag fused during iron making to be imported in the holding furnace, cushion with modified after, put into pattern and cool off, cut then, make the cinder brick or the slag plate of standard.Also can import slag fused during iron making in the holding furnace, cushion, add the 1-2% whipping agent, put into pattern again and cool off, cut then, make the foamed heat insulating building materials of standard with modified.

Claims (2)

1. the processing method of a disposing iron making slag without water, it is characterized in that its processing method for earlier slag fused during iron making being imported in the holding furnace, cushion with modified after, putting into pattern cools off, cut then, make the cinder brick or the slag plate of standard.
2. the processing method of a kind of disposing iron making slag without water according to claim 1, it is characterized in that also can importing slag fused during iron making in the holding furnace, cushion with modified, add the 1-2% whipping agent, putting into pattern again cools off, cut then, make the foamed heat insulating building materials of standard.
