Examples
Embodiment 1
[0025] The castable for ladle integral pouring working lining with alumina-spinel composite material as aggregate is made by mixing the following raw materials by weight percentage: 72% alumina-spinel composite phase aggregate, 10% Corundum fine powder, 14% alumina fine powder, 4% binder; plus 1% dispersant, 0.01% explosion-proof agent, 0.1% anti-bleeding agent.
[0026] In this example, the alumina-spinel composite phase aggregate is divided into four grades according to the particle size: 5mm
Embodiment 2
[0028] The castable for ladle integral pouring working lining with alumina-spinel composite material as aggregate is made by mixing the following raw materials by weight percentage: 65% alumina-spinel composite material, 15% corundum Fine powder, 15% alumina fine powder, 5% binder; plus 0.1% dispersant, 0.05% explosion-proof agent, 0.05% anti-bleeding agent.
[0029] In this example, the alumina-spinel composite phase aggregate is divided into four grades according to the particle size: 5mm
Embodiment 3
[0031] The castable for ladle integral pouring working lining with alumina-spinel composite material as aggregate is made by mixing the following raw materials by weight percentage: 68% alumina-spinel composite phase aggregate, 15% Corundum fine powder, 10% alumina fine powder, 7% binder; plus 0.15% dispersant, 0.05% explosion-proof agent, 0.2% anti-bleeding agent.
[0032]In this example, the alumina-spinel composite phase aggregate is divided into four grades according to the particle size: 5mm
