Ukuze uhlawule okanye uphucule ukusebenza kwe-refractory castable, kuyimfuneko yokongeza i-particle refractory okanye i-fine refractory powder (ebizwa ngokuba yizinto ezikhethekileyo ezongezelelweyo okanye i-admixtures) kunye namacandelo ahlukeneyo ahlukeneyo kwizinto eziphathekayo.
Ngokuqhelekileyo, izinto ezidityanisiweyo ngaphantsi kwe-5% (iqhezu lobuninzi) kwaye zikwazi ukuphucula ukusebenza kunye nokusebenza kokwakhiwa kwezinto ezisisiseko ezifunekayo zibizwa ngokuba yi-admixtures;Ukuba umxholo wezinto ezongeziweyo ungaphezulu kwe-5%, kuthiwa yi-additive.Kwisicelo esisebenzayo, izongezo zikwabizwa ngokuba zii-admixtures.I-Admixtures idlala indima enkulu kwii-agent ezibophelelayo kunye nezixhobo ezisisiseko.Kukho iintlobo ezininzi zazo, kwaye uhlobo ngalunye lunomlinganiselo othile wokusetyenziswa.Ngoko ke, izongezo kufuneka zimiselwe kwaye zikhethwe ngokweemfuno zokusebenza kwee-refractory castables.
Umzekelo:
(1) Kwii-refractory castables kunye ne-shrinkage enkulu yokutshisa, ubungakanani obuthile bezinto zokwandisa kwizithako ziya kusetyenziswa ukuhlawulela ukucutha kwayo umthamo, ukuqinisekisa ukuzinza komthamo, kunye nokuthintela ukusabalalisa kunye nomonakalo wesakhiwo.

(3) Xa kuyimfuneko ukuqhubela phambili nokuphucula kunye nokunyusa ukunyanzeliswa kwee-refractory castables, umlinganiselo othile wamacandelo kunye nokunyanzeliswa okuphezulu kunokongezwa kwizithako zokuthintela ukungena kwe-slag ngaphakathi kwayo.
(4) Ukuqhubela phambili ukuphucula ukuxhathisa kwe-corrosion ye-refractory castables, inani elithile lezinto ezinokuphucula ukuxhathisa kwe-corrosion ye-refractory castables okanye izinto ezinokunyusa i-viscosity ye-slag zingongezwa kwizithako.
(5) Ngokubanzi, i-composite refractory castable kufuneka yongezwe kunye ne-antioxidant ukuvimbela umonakalo we-oxidation yezinto kunye nokwandisa ubomi bayo benkonzo.
Ukusebenza okuphezulu kwe-refractory castables ngokuqhelekileyo kusebenzisa i-admixtures edibeneyo, oko kukuthi, ii-admixtures ezininzi zisetyenziselwa kunye ukuqinisekisa isalathisi esiqhelekileyo sokushisa kunye nokusebenza okuphezulu kobushushu bezinto.
