What is the effect of the brick joints between izitena ezikhanyelayo?

Izitena ezidibeneyo phakathi kwezitena eziphikisayo aziboneleli nje kuphela umjelo wokungena kunye nokukhukuliseka kwe-slag etyhidiweyo ephezulu yobushushu ekusebenzeni, kodwa ukutshatyalaliswa kwe-slag ngokwayo kukhuthaza ukwanda okuqhubekayo kwezitena. Ezi ziphumo zimbini zonyusa indawo yokunxibelelana phakathi kwe-slag kunye necala lesitena esichasayo, ukwenzela ukuba icala lesitena esichasayo lithwale uxinzelelo olugqithisileyo ngexesha lokunciphisa kunye nokwandiswa komjikelo obangelwa ukushisa. I-slag yonakalisa izitena zesithando somlilo kungekhona nje kuphela kwi-radial direction of the refractory brick in the cracks, kodwa kunye nomjikelezo wayo. Ngokukodwa xa kukho ukuqhekeka kweendandatho kwicala lesitena esichasayo, isantya sokukhukuliseka kwendandatho sikhawuleza, sibangela ukuba umphezulu wesitena esichasayo ukhuphe njengebhloko. Ngako oko, ukuchithwa okujikelezayo kwezitena eziphikisayo kunempembelelo enkulu kubomi bezitena eziphikisayo kunezitena ze-radial.
