Hva er kvaliteten på mørtel i kjerneløs induksjonsovn?

En god spolesement har:

1) God isolasjonsytelse – på grunn av den kjerneløse induksjonsovnens spoledesign, er det et visst gap mellom svingene på spolen, og nå er den gode fyllingen mellom svingene denne typen materiale. Vi har brukt shakeren til å være 1 talent under tilstanden 10000 volt tåler spenning. Tykkelsen på spolesementprøveblokken har en meget høy isolasjonsmotstand.

2) High refractoriness—Generally, the refractoriness of this high alumina-based coil cement can reach 1760C. Therefore, in the range of our molten cast iron 1530-1580C and molten cast steel 1650-1720C, the coil cement is sufficient to resist The molten metal penetrates into the coil paste, and the induction coil is protected.

Here are some technical indicators of a classic CA340 coil glue made by Saint-Gobain, which can be provided for reference:

Coil paste application (use): some coil paste is applied to the induction coil, or it can be poured into a certain thickness of insulation and heat insulation protection layer according to the design requirements of the internal test of the coil through the method of casting in the manufacturing mold. This method is generally adopted in the homes of electric furnace manufacturers. Recently, we have poured a 50-ton coreless induction furnace. In addition, I have a customer who used coil cement to repair the nozzle of an induction electric furnace. I heard that the repaired nozzle is still more durable. Of course, coil mortar is actually a type of castable for our professional refractory materials, but its aggregate is fine. It can be used to repair the erosion and cracks of some ladle and other lining materials. .
