What effect does the quality of the alumina neutral ramming material have on the life of the induction furnace?

Ubora wa nyenzo za kukataa na utendakazi wake huchukua jukumu la msingi katika maisha ya huduma ya tanuru.

(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) Muundo wa vifaa vya kinzani. Uchafu katika vifaa vya kukataa unaweza kuunda misombo yenye pointi za chini za kuyeyuka kwa joto la juu, na hivyo kupunguza refractoriness ya vifaa vya kukataa. Kwa hiyo, maudhui ya quartz katika mchanga wa tanuru ya tanuru lazima ihakikishwe, na utungaji wa uchafu lazima udhibitiwe madhubuti. Utungaji wa mchanga wa tanuru ya tanuru hudhibitiwa kama ifuatavyo: ω (SiO2) ≥ 98.0%; ω (Al2O3) ≤ 0.5%; ω (Fe2O3) ≤ 0.5%; ω (TiO2) ≤ 0.05%; ω (H2O) ≤ 0.5%.

(3) Granularity ratio of refractory materials. The reasonable particle size ratio of refractory materials can easily form a high-density refractory layer during the furnace building process, and defects are not easy to appear during the use process. The following is a set of reasonable ratios: 3.35mm～5mm, 0.85mm～1.70mm, 0.1mm～0.85mm, and the proportions below 0.1mm are 17%, 33%, 20%, and 30% respectively.
