Naon pangaruh kualitas bahan ramming nétral alumina dina kahirupan tungku induksi?

Kualitas bahan réfraksi lapisan sareng performa na ngagaduhan peran penting dina kahirupan jasa tungku.

(1) Refractory materials for furnace construction must have a high degree of refractoriness, resist high-temperature heat load, and do not soften or melt. At the same time, it must have high volume stability, resist high temperature heat load, and have no volume shrinkage and only uniform expansion.

(2) Komposisi bahan refractory. Kotoran dina bahan refraktori tiasa ngabentuk sanyawa kalayan titik lebur rendah dina suhu anu luhur, ku kituna ngirangan refractoriness bahan refraktori. Ku alatan éta, eusi quartz dina keusik pinding tungku kudu ensured, sarta komposisi impurity kudu mastikeun dikawasa. Komposisi keusik lapisan tungku dikawasa saperti kieu: ω (SiO2) ≥ 98.0%; ω (Al2O3) ≤ 0.5%; ω (Fe2O3) ≤ 0.5%; ω (TiO2) ≤ 0.05%; ω (H2O) ≤ 0.5%.

(3) babandingan Granularity bahan refractory. Babandingan ukuran partikel lumrah bahan refractory bisa kalayan gampang ngabentuk lapisan refractory dénsitas tinggi salila prosés ngawangun tungku, sarta defects henteu gampang muncul dina mangsa proses pamakéan. Di handap ieu susunan babandingan nu lumrah: 3.35mm～5mm, 0.85mm～1.70mm, 0.1mm～0.85mm, jeung babandingan handap 0.1mm masing-masing 17%, 33%, 20%, jeung 30%.
