2. The physical and chemical index for the ceramic sprue tube
Item | Al2O3 Content % | Refractoriness ℃ | 0.2Mpa start point temper of refractoriness under load ℃ | Reheating linear change (1400℃.2h) | Apparent porosity % | Cold crushing strength.Mpa |
Standard | ≥45 | ＞1700 | ≥1280 | +0.2 -1.5 | ≤28 | ≥30 |
Paper tube for casting is Eco-friendly,cost-effective and an ideal replacement of ceramic tube.It can improve casting quality,reduce scrap,improve the quality of reclaimed sand,reduce work intensity.
The high efficient exothermic insulation riser has low density,high strength and good toughness, which suit for all kinds of black and non-ferrous casting.
