Embodiment 1

[0012] In this embodiment, the crack repair at the junction of the furnace nozzle and the furnace body of a 50kg vacuum induction furnace crucible is taken as an example:

[0013] A vacuum induction furnace crucible repair method, the specific steps are as follows:

[0014] 1. Remove the steel slag inside the crack and clean the scum.

[0015] 2. Spread the water glass evenly on the cracks, pay attention to the cold state of the crucible, and do not apply too much.

[0016] 3. For the furnace nozzle material ratio repair material, use 40-70 mesh magnesia and ≥80 mesh magnesia powder in a ratio of 1:2, and mix evenly with water glass cold binder.

[0017] 4. Knead the prepared magnesia into a ball. The diameter of the ball is 1.2 times the depth of the crack. Evenly stick the magnesia ball on the repaired place, smash it with a hammer and level it. The magnesia material should be repaired in time to avoid repairing. material dry.

[0018] 5. Finally, clean up the excess magn...

Abstract

The invention relates to a vacuum induction furnace crucible repair method, and belongs to the technical field of vacuum induction furnace crucible preparation. The vacuum induction furnace crucible repair method comprises the concrete steps of firstly carrying out crack analysis, and then carrying out crack cleaning; then uniformly applying sodium silicate onto cracks under the cold state of a crucible; during the preparation of a repair material, matching magnesia with different granularity according to the proportion, and uniformly stirring through a sodium silicate cold-binder; and finallykneading the prepared magnesia into a spherical shape, uniformly pasting onto the repair part, and leveling, wherein the diameter of the spherical shape is 1.2 to 1.3 times of the crack depth. The vacuum induction furnace crucible repair method has the advantages that the service life of the crucible can be prolonged, and the occurrence of a steel leakage accident during smelting is avoided.

Description

technical field [0001] The invention belongs to the technical field of vacuum induction furnace crucible preparation, and in particular relates to a vacuum induction furnace crucible repair method. In particular, it relates to a crucible repair method for knotting electric fused magnesia in a vacuum induction furnace. Background technique [0002] In the small furnace smelting test process, due to the discontinuous test, cracks of different degrees appear after the crucible cools down. When the smelting reaches the middle and late stages, the crucible cracks are obvious and begin to fall off. If it is not repaired in time, it will easily leak steel during the smelting process. And the induction coil is broken down, causing a steel leakage accident. Contents of the invention [0003] The purpose of the present invention is to provide a method for repairing the crucible of a vacuum induction furnace, which solves the problem of steel breakout accidents during the smelting p...
