What are the components of induction furnace knotting tools?

The following tools are generally used for forno ad induzione dry knotting: 6 degassing forks (3 long and 3 short), 1 tamping side hammer, 1 handheld vibrator, and 2 pneumatic vibrators, as shown in the figure below.

1. Degassing fork

The tines at the bottom of the degassing fork are arranged side by side, and the front ends of the tines are sharper. They are mainly used to fork the furnace lining material added around the crucible mold evenly and stiffly, and then put the knotted furnace lining on the upper surface of the former layer before adding the latter layer of material. Line loose. In the process of knotting, the air in the lining material is manually removed, so as to achieve the pre-compacting effect of the lining material. The length of the fork teeth should be greater than or equal to the height of the lining material added each time, and in order to achieve the transmission of the impulse of the electric vibrator to the junction of the previous layer and this layer without affecting the efficiency, a tooth length of 100~120mm is more appropriate. Before the furnace is built, the tines must be repeatedly inserted into the molding sand to remove rust to prevent the rust from falling into the furnace lining and affect the quality of the furnace lining.

2. Tamping the side hammer

The shape is similar to the circumference of the crucible and the size is moderate. A special side hammer is prepared to compact on the surface of the furnace lining, which can ensure that the knotted furnace wall has a higher density (above 2.1g/cm3). At the same time, it can be used in conjunction with the Boss vibrator to compact and compact the lining on the slope. .

3. Handheld vibrator

Vibration can be generated when the power is turned on, which is mainly used for compaction and compaction of the furnace lining material at the slope of the furnace lining.

4. Pneumatic furnace building machine

Pneumatic furnace building machine is mainly divided into vibrator for furnace wall and vibrator for furnace bottom. Its main function is to pneumatically vibrate the lining material after the charge is added, which can reduce the lack of tightening of the lining caused by the deviation of the manpower degassing force. Even, to ensure the overall uniformity and compactness of the furnace lining material, so as to ensure the service life of the furnace lining.
