E le ho lefella kapa ho ntlafatsa ts'ebetso ea refractory castable, hoa hlokahala ho eketsa likaroloana tsa refractory kapa phofo e ntle ea refractory (eo ho thoeng ke lisebelisoa tse khethehileng tsa tlatsetso kapa li-admixtures) tse nang le likarolo tse fapaneng tse ka sehloohong ho thepa.
Ka kakaretso, lisebelisoa tse kenyellelitsoeng ka tlase ho 5% (karolo ea bongata) mme li khona ho ntlafatsa ts'ebetso le ts'ebetso ea kaho ea lisebelisoa tsa mantlha tse hlokahalang li bitsoa li-admixtures;Haeba litaba tsa lintho tse ekelitsoeng li phahame ho feta 5%, li bitsoa additive.Ts'ebetsong e sebetsang, li-admixtures li boetse li tsejoa e le li-admixtures.Li-admixtures li bapala karolo ea bohlokoa ho li-agent tse tlamang le lisebelisoa tsa mantlha.Ho na le mefuta e mengata ea tsona, 'me mofuta o mong le o mong o na le sebaka se itseng sa tšebeliso.Ka hona, li-additives li lokela ho khethoa le ho khethoa ho latela litlhoko tsa ts'ebetso ea li-castable tse refractory.
Ka mohlala:
(1) Bakeng sa li-castable tse refractory tse nang le shrinkage e kholo ea ho chesa, palo e itseng ea lisebelisoa tse atolositsoeng ka har'a metsoako e tla sebelisoa ho lefella ho fokotseha ha molumo oa eona, ho netefatsa botsitso ba molumo, le ho thibela ho phatloha le ho senyeha ha mohaho.
(2) Ha ho hlokahala ho tsoela pele ho ntlafatsa kapa ho matlafatsa ho hanyetsa mocheso oa li-refractory castables, palo e loketseng ea lisebelisoa tse thata li lokela ho eketsoa ho metsoako ho ba fa ts'ebetso e sa tšoaneng le ho ntlafatsa botsitso ba bona ba mocheso.
(3) Ha ho hlokahala ho ntlafatsa ka ho eketsehileng le ho ntlafatsa ho se tsitse ha li-castables tse hanyetsang, palo e itseng ea likarolo tse nang le ho se lekane ho phahameng li ka eketsoa ho metsoako ho thibela ho kenella ha slag ka hare ho eona.
(4) Ho tsoela pele ho ntlafatsa ho hanyetsa ha kutu ea li-castable tse refractory, lisebelisoa tse itseng tse ka ntlafatsang ho hanyetsa ha kutu ea li-castable tse hanyetsanang kapa lisebelisoa tse ka eketsang viscosity ea slag li ka eketsoa ho metsoako.
(5) Ka kakaretso, composite refractory castable e lokela ho eketsoa ka antioxidant ho thibela tšenyo ea oxidation ea thepa le ho lelefatsa bophelo ba eona ba ts'ebeletso.
Li-castable tse phahameng tsa ts'ebetso e phahameng hangata li sebelisa li-admixtures tse kopaneng, ke hore, li-admixtures tse 'maloa li sebelisoa hammoho ho netefatsa index ea mocheso e tloaelehileng le ts'ebetso e phahameng ea mocheso oa thepa.
