Induction furnace refractory manufacturers take you to understand the role of induction furnaces

The induction furnace refractory manufacturer tells you that the induction furnace is to put the scrap steel waiting for the raw material to be melted in the furnace. When the induction coil is energized, it generates a large electromagnetic field and makes the raw material in the induction furnace produce a large pot flow, causing the raw material Heat, heat and melt.

By adding metallurgical auxiliary materials such as ferroalloys, the added raw materials are smelted into steel of the required composition and quality, and cast into castings.
Induction furnace refractory manufacturers tell you that induction furnaces are generally small and are mainly used to smelt castings and steel for some precision castings. In recent years, it has also been used to smelt stainless steel. It uses relatively simple refractory materials, generally knotted materials. For the induction furnace for melting cast iron, quartz ramming material is generally used, and the service life is 20-40 heats.
When smelting the steel of some precision castings, the smelting temperature is high, the smelting conditions are also poor, the service life of the quartz ramming material is greatly reduced, and it can no longer meet the requirements of use. At this time, the magnesium dry ramming material is used. There are also aluminum-silicon series ramming materials, and some induction furnaces use ready-made crucibles. Dry ramming material is compacted, this method is easy to replace and can improve the utilization rate of equipment.
Induction furnace refractory manufacturers tell you that crucibles are generally used for casting of castables with a chemical composition similar to dry-knotted materials, and are hardened and dried, high-quality alkaline dry-type ramming materials or corundum spinel The service life of the ramming material can reach more than 70 heats.
The advantages of dry ramming lining are: low cost, not easy to crack, low accident rate such as steel infiltration and steel breakout, and the sintering is thin, and it is easy to dismantle the furnace. Then there is no sintering of the dry material behind, the density is very low, the thermal insulation effect is low, the thermal insulation effect is good, and it does not contain moisture.
Therefore, it can be used directly without an oven, so it is very advantageous for reducing consumption and improving efficiency.
Induction furnace refractory manufacturers tell you that induction furnaces are divided into core and coreless, coreless intermittent furnaces, and refractory materials are still very harsh.
