Njerwa ya Checker ndi mtundu wa sing'anga yotengera kutentha, yomwe imagwiritsidwa ntchito makamaka kumtunda wapakatikati wachipinda chowongolera mu chitofu choyaka moto chosungirako kutentha panthawi yoyaka. Checker firebrick imagwira ntchito yofunika kwambiri pakuwotha mphepo yozizira mpaka mphepo yotentha kudzera pakusinthana kwa kutentha kwa convective ndi kutengera kutentha kwa radiation munthawi ya kuphulika. Checker fire block imagwiritsidwa ntchito kwambiri mumakampani osungunula chitsulo ngati mtundu wa chonyamulira chotenthetsera chomwe chimakhala ndi luso lamphamvu la kutentha kwamphamvu, malo akulu osungiramo matenthedwe, mpweya wabwino komanso kukana kochepa. Checker refractory block imagwiritsidwa ntchito makamaka mu chitofu choyaka moto.
Njerwa zamoto za Checker ndi sing'anga yotengera kutentha, zimagwira ntchito munthawi yosungirako kutentha kwa ng'anjo, mumlengalenga ndi kusinthanitsa kutentha kwa convection ndi kusinthanitsa kutentha kwa radiation, mpweya wozizira umatenthedwa ndi mphepo yotentha. zomwe zimagwiritsidwa ntchito mu chipinda chosungiramo kutentha kwa ng'anjo yotentha, nthawi zambiri zimakonzedwa mwadongosolo m'chipinda chosungiramo zinthu.
njerwa zomangira zokhala ndi dzenje lowoneka bwino komanso kuchuluka kwa zinthu zam'mbali zomwe zimayenderana, ndipo njerwa zowoneka bwino zili munjira ziwiri zofananira pamwamba pa chotupa choyikapo ndi poyambira. ma checker fire blocks ali ndi kukhazikika kwa voliyumu yabwino komanso magwiridwe antchito apamwamba kwambiri ndiabwino kwambiri, kachulukidwe kwambiri komanso kutsika kochepa.
Zotchingira moto za Checker zimakhala ndi mphamvu yosinthira kutentha kwambiri, malo akulu osungiramo matenthedwe, mpweya wabwino komanso kukana kochepa. ma checker blocks ndi mtundu wa njerwa zotengera kutentha kwapakati. zotchingira zimayikidwa m'chipinda chosungiramo kutentha cha ng'anjo yophulika ndi chitofu choyaka moto.

Njerwa yoyaka moto imagwiritsidwa ntchito makamaka muchipinda chosinthira cha chitofu choyaka moto. Ikani njerwa yoyang'ana ndi mawonekedwe enaake ndi mabowo mu dongosolo ndipo mpweya ukhoza kudutsa m'mabowo okwera ndi pansi. komanso njerwa yowunikira imagwiritsidwa ntchito mu Iron ndi Steel Industry populumutsa mphamvu yokhala ndi mawonekedwe abwino kwambiri otentha monga kusinthana kwamphamvu kwa kutentha, malo akulu osungira kutentha, mpweya wabwino, kukana pang'ono ndi zina.
RS refractory fakitale monga katswiri wopanga njerwa zamoto ku China, ali ndi zabwino zambiri zopikisana pamsika. ngati muli ndi zofuna za checker fire block, kapena muli ndi mafunso pa checker firbrick zokhudzana ndi zizindikiro za thupi ndi mankhwala, chonde titumizireni kwaulere, tidzakupatsirani njerwa zapamwamba za efractory.
