Abstract
The technique that a kind of shaft furnace burns magnesium iron spinel sand is related to magnesium iron spinel sand field.A kind of shaft furnace burns the technique of magnesium iron spinel sand, includes the following steps；1, special B magnesites are crushed to less than 200 cm, are put into light baking kiln gas station；By 1200 degree or more of high temperature sintering, the pure Qing Shao Magnesium powder of Gao is sintered into.2, di-iron trioxide will be added in light-burning magnesium powder, 350 mesh or more is crushed to by Raymond machine device.3, it is rolled 1 hour or more by high temperature, output Qing Shao Magnesium balls.4, in coal and Qing Shao Magnesium balls mixing input shaft furnace, the method being combined using open fire and dying fire, temperature is at 1800 degree or more.The present invention greatly increases production efficiency and reduces cost.
Description
Technical field
The present invention relates to the techniques that magnesium iron spinel sand is burnt in magnesium iron spinel sand field more particularly to a kind of shaft furnace.
Background technology
Magnesium iron spinel sand is also known as high ferro magnesia, is mainly used for basic refractory, for beating mafic spinel brick.It is existing
The technique of the magnesium iron spinel sand used in technology is generally used following methods.1, capacitance is sintered：It is sintered using capacitance
, it is to be bound directly with Qing Shao Magnesium powder and brown iron oxide, not by rolling, is not sufficiently stirred, finished product is unstable.2, capacitance
Kiln：The problem of using electric melting furnace sintering, it is high that there are power consumption, waste national resources.Also, product list kiln is on daily 10 tons of left sides
The right side, yield are relatively low.
Invention content
For the drawbacks described above of the prior art, it is brilliant that shaft furnace a kind of at low cost and efficient provided by the invention burns magnesium iron point
The technique of stone sand.
In order to achieve the above object, the present invention provides the following technical solutions：
A kind of technique that shaft furnace burns magnesium iron spinel sand, it is characterised in that：Include the following steps；
1, special B magnesites are crushed to less than 200 cm, are put into light baking kiln gas station；It is burnt by 1200 degree or more of high temperature
Knot, sinters the pure Qing Shao Magnesium powder of Gao into.
2, di-iron trioxide will be added in light-burning magnesium powder, 350 mesh or more is crushed to by Raymond machine device.
3, it is rolled 1 hour or more by high temperature, output Qing Shao Magnesium balls.
4, it puts into shaft furnace, in coal and Qing Shao Magnesium balls mixing input shaft furnace, the method being combined using open fire and dying fire, temperature
It is more stable to burn the product come at 1800 degree or more in this way for degree.
As a preferred embodiment, in the step 3, the Qing Shao Magnesium balls will be dried 24 hours or more.
As another preferred embodiment, in the step 4, the coal is anthracite.
Compared with the prior art, the invention has the advantages that：
The present invention solves in the prior art by shaft furnace sintering, the unstable problem of the finished product that capacitance is susceptible to when being sintered.
Also, output per day compares 10 tons of the daily output of electric melting furnace at 100 tons or so.Greatly increase production efficiency.In addition, electric smelting
Kiln electricity consumption is big, we are sintered using anthracite, greatly reduce cost.
Specific implementation mode
Further to illustrate the technological means and its effect of the invention taken, below in conjunction with the preferred implementation of the present invention
Example is described in detail.
A kind of technique that shaft furnace burns magnesium iron spinel sand, it is characterised in that：Include the following steps；
1, special B magnesites are crushed to less than 200 cm, are put into light baking kiln gas station；It is burnt by 1200 degree or more of high temperature
Knot, sinters the pure Qing Shao Magnesium powder of Gao into.
2, di-iron trioxide will be added in light-burning magnesium powder, 350 mesh or more is crushed to by Raymond machine device.
3, it is rolled 1 hour or more by high temperature, output Qing Shao Magnesium balls.Qing Shao Magnesium balls will be dried 24 hours or more.
4, it puts into shaft furnace, coal（Anthracite）It mixes in input shaft furnace with Qing Shao Magnesium balls, is combined using open fire and dying fire
Method,（Be exactly the flame of coal combustion outside and the inside）It is more stable to burn the product come at 1800 degree or more in this way for temperature.
The Magnesium iron spinel sand furnace life that we give birth to production can guarantee at 1 year or more, more preferable with kliner coating is hung on cement kiln,
It preferably ensure that the production needs of cement kiln.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
Those familiar with the art in the technical scope disclosed by the present invention, can easily think of the change or the replacement, and should all contain
Lid is within protection scope of the present invention.Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
