Description
Technical field
The present invention relates to the method for the big crystallization fused magnesite of One-step production, belong to technical field of refractory materials.
Background technology
Then existing big crystallization fused magnesite passes through phase in the preparation, it is necessary to first carried out to high-quality giobertite light-burned
Answer kiln to carry out secondary clacining, finally can just produce big crystallization fused magnesite.There is energy resource consumption using above-mentioned preparation method
The deficiency such as height, production procedure length, input cost height.
The content of the invention
The method that the present invention provides a kind of big crystallization fused magnesite of One-step production, it is therefore an objective to reduce technological process, is reduced
Energy resource consumption.
The concrete technical scheme of the present invention is as follows：The method of the big crystallization fused magnesite of One-step production, including in detail below
Step：
（1）Magnesite is selected：Select MgCO3Middle content of MgO is 45% -47.81% giobertite；
（2）Milling：Granularity is made for 3 mesh --- the powder of 3500 mesh in giobertite；
（3）Pressure ball：By step（2）Obtained powder adds agglutinant and added water and stirs, and pellet is pressed into ball press,
Sphere diameter 3mm-200mm；
（4）Sintering：Finally by pellet input mineral hot furnace roasting, you can produce big crystallization fused magnesite.
The agglutinant is the one or more in magnesia, borax, carbon.Adding magnesia and borax agglutinant can be with
Accelerate to smelt speed, rapid condensation prevents from spraying stove；Interior energy can be increased by adding carbon, and in the case of a high temperature, carbon is in ball internal combustion
Heat release is burnt, accelerates the reaction of ball internal chemical, improves product quality.
The present invention can be according to MgCO in giobertite3And the difference of content of MgO produces the big crystallization magnesia of different class,
Respectively 99% big crystallization magnesia, 98.5% big crystallization magnesia, 98% big crystallization magnesia 97% crystallization magnesia etc. greatly.
Beneficial effects of the present invention：The present invention can produce big crystallization fused magnesite using one-step method, relative to existing
Technology, not only reduces technological process, reduction energy resource consumption, and ensure that big crystallization fused magnesite has preferable quality.
