AI Technical Summary

Technical Problem

In existing lifting-type medium-frequency electric furnaces, air bubbles are difficult to effectively remove during the melting process of metal materials, resulting in porosity defects on the surface of castings and affecting production quality.

Method used

By setting up a vibration structure and a filtration structure inside the medium-frequency furnace, the furnace is moved up and down using a lifting structure, and the vibration structure causes the air bubbles inside the crucible to vibrate and be expelled. At the same time, the filtration structure purifies the smoke and dust, reducing the emission of harmful substances.

Benefits of technology

It effectively removes air bubbles from the molten water, reduces the surface tension of the molten metal, reduces porosity defects in castings, and improves the quality of casting production.

Abstract

The utility model relates to the technical field of intermediate frequency electric furnace, concretely relates to a lifting type intermediate frequency electric furnace, including support frame, still including melting mechanism, melting mechanism includes melting structure, lifting structure, melting structure includes the intermediate frequency furnace of up and down removal setting in the upper portion of support frame, is equipped with the crucible in the upper portion of check ring, is equipped with vibration structure between support column and intermediate frequency furnace, is equipped with the filter structure in the upper portion of support frame. Advantageous effects: through melting structure will metal material accelerate melting and form melt water, start lifting structure drive intermediate frequency furnace up and down movement to metal material even heating, and make the crucible produce certain vibration, and then the melt water in the inside of crucible is vibrated, and then the bubble vibration remaining in the inside of melt water is discharged outward, thereby slight vibration can reduce metal liquid surface tension, promote internal bubble to float and discharge, reduce casting air hole defect, improve the casting production quality.
