bata refraktori mlengkung ngandhut Al2O3 babagan 30% ~ 45%, lan isi silika luwih murah tinimbang 78%. bata refraktori mlengkung kalebu bahan refraktori asam lemah. pemblokiran refractory sudhut mlengkung tahan kanggo slag asam lan erosi saka gas asam, nanging kemampuan resistance alkali punika dicokot miskin. pamblokiran refractory sudhut mlengkung duwe karakter kinerja termal apik lan resistance kejut termal apik.
