Matters needing attention in the use of intermediate frequency furnace charge (1)

Improving the service life of the charge of the induction intermediate frequency furnace is the policy that every foundry worker seeks, and it will also be of great significance to the enterprise. So what special attention should we pay when using the charge of the intermediate frequency furnace? You can follow the editor below. Find out.

1. The quality of the furnace lining refractory and its function have a fundamental effect on the service life of the furnace.

2. The electric furnace charge must have good performance, and it is required that the material has a suitable high refractoriness, resists high temperature heat load effect, does not core soft, does not melt, has high volume stability, resists high temperature heat load effect, and does not shorten the volume. And only uniform expansion, with moderately high normal temperature strength and high temperature thermal strength, high load softening temperature, under the combined effect of high temperature thermal load and heavy load, does not lose strength, does not occur creep and collapse, has good Thermal shock resistance, resistance to rapid changes in temperature, no cracking, no falling off, and good slag resistance.

3. Due to the moderately fast heating rate of the intermediate frequency furnace, when the smelter does not pay attention, the electric furnace charge presents a "bridging" phenomenon and the furnace lining material exhibits a local high temperature or even exceeds the refractoriness of the furnace lining, which may cause the furnace lining to be melted and corroded; Or when the furnace worker does not pay attention, when the melting temperature is too high, the furnace lining may be melted and corroded; this will greatly reduce the service life of the furnace lining. Therefore, attention must be paid at any time during the melting process. , The furnace worker can grasp the temperature of the molten iron at any time according to the color of the molten iron to ensure the safety of the furnace lining.
