Phosphate refractory bricks yog tsim los ntawm ci ntawm 550-600 degree nrog phosphoric acid los yog lub teeb txhuas phosphate raws li cov binder. Lawv yog unburned refractory cib thiab yog cov khoom alkaline. Lawv feem ntau siv hauv cov cement teb kilns, ncej kilns thiab txiv qaub kilns
Thaum lub sij hawm tsim cov phosphate cib, cov khoom sib xyaw yuav tsum tau daig rau ntau tshaj 16 teev, vim hais tias thaum lub sij hawm cov txheej txheem ntxiab, cov phosphoric acid reacts nrog hlau nyob rau hauv cov av nkos kom tso pa roj, uas tsis yog yooj yim los tsim spalling thaum molding, thiab yuav tsis lo rau pwm, ua rau pitting
Nyob rau hauv cov txheej txheem ci, cov binder ntawm phosphate refractory bricks hardens. Thaum rhuab mus rau qhov kub thiab txias, lub cev qhuav dej polymerization cov tshuaj tiv thaiv yuav tshwm sim, ua kom muaj zog adhesion, ua rau qhov ntom thiab lub zog ntawm cov ntaub ntawv siab dua. Ntawm 1200-1300 degree, qhov hnav tsis kam yog txhim kho ntxiv, thiab lub neej kev pab cuam ntawm lub cub tawg tau nce. Yog li ntawd, phosphate refractory bricks tseem hu ua phosphate hnav resistant bricks.
