I-Checker Brick luhlobo lwesixhobo sokudlulisa ubushushu, esisetyenziswa ikakhulu kwindawo ephakathi ephezulu yegumbi lokuhlaziya kwisitovu esitshisayo sokugcina ubushushu ngexesha lokutshisa. I-checker firebrick idlala umsebenzi obaluleke kakhulu kwinkqubo yokufudumeza umoya opholileyo ukuya kumoya oshushu ngokutshintshiselana kobushushu obuguqukayo kunye nokudluliselwa kobushushu bemitha ngexesha loqhushumbo. ibhlokhi yomlilo we-checker isetyenziswa kakhulu kwishishini lokunyibilikisa isinyithi njengohlobo lokuthwala ubushushu kunye nokusebenza okugqwesileyo kobunjineli be-thermal obunamandla okutshintsha ubushushu, indawo enkulu yokugcina i-thermal, umoya opholileyo kunye nokuchasana okuphantsi. ibhloko ye-checker refractory isetyenziswa ikakhulu kwisitovu esiqhumayo.
Izitena zomlilo ze-Checker ziyindawo yokudlulisa ubushushu, zidlala indima kwixesha elitshisayo lokugcina ubushushu, emoyeni yi-convection yokutshintshwa kobushushu kunye nokutshintshwa kobushushu bemitha, umoya obandayo ufudunyezwa kumoya oshushu. esetyenziswa kwindawo yokugcina ubushushu bomlilo wesithando somlilo, ngokuqhelekileyo ihlelwe ngokucwangcisiweyo kwindawo yokugcina.
Izitena zokujonga ezinomngxuma ocacileyo kunye nobuninzi bemigangatho yecala ehambelanayo enye kwenye, kunye nezitena ze-checker refractory zifumaneka kwi-parallel ezimbini kumphezulu we-bulge yokumisa kunye ne-groove yokumisa. Iibhloko zomlilo zokutshekisha zinozinzo lwevolyum elungileyo kunye nokusebenza komthwalo ophezulu wokuhamba kuhle kakhulu, ukuxinana okuphezulu kunye ne-porosity ephantsi.
Iibhloko zomlilo ze-Checker zinamandla okutshintshana kobushushu, indawo enkulu yokugcina i-thermal, umoya opholileyo kunye nokuchasana okuphantsi. iibhloko zokujonga luhlobo lwezitena ezidlulisa ubushushu eziphakathi. iibhloko zokutshekisha zisetyenziswa kwigumbi lokugcina ubushushu lesithando somlilo kunye nesitovu esitshisayo.

Izitena zokujonga umlilo zisetyenziswa ikakhulu kwigumbi elihlaziyayo lesitovu esiqhumayo. Beka isitena sokukhangela kunye nesakhiwo esithile kunye nemingxuma ngokulandelelana kwaye irhasi inokudlula kwimingxuma ephezulu nasezantsi. kwakhona isitena sokukhangela sisetyenziswa kwi-Iron kunye ne-Steel Industry ukonga amandla kunye neempawu ezininzi ezibalaseleyo ze-thermal ezifana nokutshintshiselana kobushushu obuqinileyo, indawo enkulu yokugcina ubushushu, umoya opholileyo, ukuxhathisa okuphantsi kunye nokunye.
Umzi-mveliso we-RS refractory njengomenzi wobuchwephesha wezitena zomlilo e-china, uneenzuzo ezininzi zokukhuphisana kwimarike. ukuba unemfuno ye-checker fire block, okanye unemibuzo ethile kwi-checker firbrick malunga nezibonakaliso zomzimba kunye neekhemikhali, nceda uqhagamshelane nathi mahhala, siya kukubonelela ngezitena eziphezulu ze-checker efractory.
