Lintlha tse ka sehloohong tsa li-castable tse phahameng tsa aluminium

1. Likahare tse tlaase tsa samente ka har’a li-castable, ke hore, li-calcium oxide tse tlaase, li tla fokotsa tlhahiso ea lihlahisoa tse tlaase le tse bohareng, kahoo li eketsa ho hanyetsa mollo, matla a mocheso o phahameng le ho hanyetsa slag ea sehlahisoa.

2. Ts’ebeliso ea metsi e kopanyang ea castable ke metsotso e ka bang 2 feela ea ho lahla ho tloaelehileng, ‘me boima le porosity ea castable li ntlafalitsoe.

3. Ka mor’a ho bōptjoa le ho folisa, ho hlahisoa hydrate e fokolang ea samente. Nakong ea ho futhumatsa le ho baka, ha ho na palo e kholo ea tahlehelo ea metsi, ‘me matla a mocheso oa mocheso a fokotseha, empa ha mocheso o ntse o phahama, butle-butle o etsa li-sinters’ me matla a ntse a eketseha.
