Description
Technical field
The present invention relates to energy supply for metallurgy recycling and solid waste high value added utilization technical field, specifically a kind of utilizations
The method of molten state blast furnace slag one step forming microcrystal glass plate.
Background technique
Using solid waste such as flyash, metallurgical dust sludge, cullet, metallurgical slags, then pass through composition adjustment appropriate
A large amount of research has been obtained in manufacture devitrified glass.In general, used waste types are different, obtained devitrified glass
Principal crystalline phase it is also different, and then also difference is very big for its physical and chemical performance and mechanical performance.
The main component of blast furnace slag is the oxides such as calcium oxide, silica, aluminium oxide and magnesia, is production crystallite glass
The good raw material of glass.Early in the sixties in last century, steel research association, Britain begins to trial and prepares high slag microcrystallite glass,
The former Soviet Union has also almost started simultaneously at similar research work.The research in this nearest field be concentrated mainly on addition nucleating agent with
Improve crystallization process and the organizational controls of high slag microcrystallite glass.But preparation method used by these work is all tradition
Melting heat treatment method, i.e., first mixed material is melted, then cooling obtain female glass, followed by heating
Heat treatment process is completed, heat treatment process is often all completed in two steps.Obviously, such process is not only without benefit
With the heat of high-temperature liquid state blast furnace slag, but also a large amount of energy is additionally required to carry out at the melting of material and the heat of female glass
Reason.
The sensible heat energy level of blast furnace slag is very high, belongs to high-quality residual heat resources in metallurgy industry.Blast furnace slag is discharged out of blast furnace
Temperature usually at 1450 DEG C or more, a sensible heat contained by blast furnace slag per ton is roughly equivalent to the calorific value of 60kg standard coal.By
In the difficulty in recovery technology, the rate of recovery of blast-furnace cement sensible heat is extremely low at present.The blast furnace slag in China largely uses water quenching legal system
Water intaking slag, then uses as cement raw material.Although some enterprises utilize the waste heat of washing slag water for heating, it is able to solve plant area
Interior section heating or the heat supply in bathroom, but this using only accounting for 10% or so of blast furnace slag complete sensible heat, and by the time and
The limitation of region, in summer or without the southern area of warming installation, this part energy can only also be wasted.Meanwhile it rushing
Grain slag technique also needs to waste the water resource of a large amount of preciousnesses.Therefore, if the sensible heat resource of high-temperature molten-state blast furnace slag can be used for
The preparation process of devitrified glass can not only recycle the sensible heat of blast furnace slag and reduce the cost of devitrified glass preparation, while also aobvious
Write the utility value for improving blast furnace slag.
Currently, thering are some authorizations or invention disclosed patent to be related to blast furnace slag in the utilization of microcrystal glass area, such as send out
Bright patent [patent No.: 200710054035.3] proposing a kind of method for preparing devitrified glass using blast furnace slag, but use
It is still solid-state blast furnace slag after cooling, is then reheated to molten state, does not mention the sensible heat using liquid blast furnace,
There are the wastes of the energy.Patent of invention [application number: 201010274345.8] propose directly made using liquid blast furnace it is micro-
The method of crystal glass, although the sensible heat of liquid blast furnace is utilized, the auxiliary material SiO of addition2It must be molten state, and need
Ingredient stove is preheated in advance to blast furnace tapping temperature, SiO2Melting and ingredient stove be heated to tapping temperature and also need to disappear
Consume a large amount of energy.
The application has the characteristics that high heating value for molten state blast furnace slag, proposes a kind of utilization one step of molten state blast furnace slag
The method for shaping microcrystal glass plate, that is, be introduced directly into high-temperature liquid state blast furnace slag to ingredient and homogenize in stove, can greatly save
The high-temperature fusant to homogenize, is then poured into constant temperature mold by the consumption of outside resources needed for constant temperature stove, and a step is completed solidifying
Gu, forming core and crystallization and last cooling, shorten the manufacturing cycle, reduce production cost and energy consumption.
