Problems solved by technology

[0002] At present, high-alumina refractory balls are used in hot air production. It has many disadvantages, mainly in that due to its low refractoriness, it is easy to deform when used in high-temperature areas, and it will cause blockage and agglomeration due to bursting and sticking. It is troublesome to replace the sub-field. It also results in a short service life and increases cost input at the same time

Embodiment 1

[0015] A kind of production technique of producing zirconium corundum ball with capacitance method, described production technique comprises the steps:

[0016] Step 1: batching, select alumina powder, zirconia and silicon dioxide as raw materials, and mix them evenly according to a certain weight ratio;

[0017] Step 2: melting in an electric furnace, fully melting the mixed raw materials obtained in step 1 into a liquid in an electric melting furnace, wherein the melting temperature in the electric melting furnace is 2000°C;

[0018] Step 3: pouring the mold, pouring the liquid obtained in step 2 into the mold;

[0019] Step 4: insulation, the cast mold in step 3 is insulated in a sandbox;

[0020] Step 5: Out of the box, heat the mold in step 4 for 8-10 days and then out of the box to obtain semi-finished zirconium corundum balls;

[0021] Step 6: grinding, grinding the semi-finished zirconium corundum ball obtained in step 5 to obtain a finished zirconium corundum ball. ...

Abstract

The invention relates to a production process of a zirconia corundum ball through a capacitance method. The production process includes the steps of burdening, melting with an electric furnace, mold casting, heat preservation, discharging and grinding. The production process has the advantages that the service life of the zirconia corundum ball is long, energy is saved, resources are saved, environmental protection is achieved, the process is simple, the refractoriness is high, and deformation does not easily occur.

Description

technical field [0001] The invention belongs to the technical field of production of zirconium corundum balls, and in particular relates to a production process for producing zirconium corundum balls by a capacitor method. Background technique [0002] At present, high-alumina refractory balls are used in hot air production. It has many disadvantages, mainly in that due to its low refractoriness, it is easy to deform when used in high-temperature areas, and it will cause blockage and agglomeration due to bursting and sticking. It is troublesome to replace the sub-field. It also causes a short service life and increases cost input. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a production process for producing zirconium corundum balls by capacitance method, which has the advantages of long service life, energy saving, resource saving, environmental protection, simple process, high refrac...
