Yadda za a zaɓi kayan ƙuntatawa don masu ƙona shara?

Recently, many customers have inquired about refractory materials for waste incinerators. In view of the selection problems faced by customers, the editor has compiled a list of refractory materials for waste incinerators for reference only. Different types of incinerators have different selections according to their types, temperatures, and parts. Please refer to them carefully.

Masu ƙonawa na yau da kullun sun haɗa da ƙona ƙungiyoyi, ƙona ƙoshin wuta, tsarin ƙonawa na CAO, masu ƙona gado mai jujjuyawa, da masu ƙona wutar makera. Kayan ƙyama don masu ƙona shara suna da halaye masu zuwa:

① Good volume stability; ② Good high temperature strength and wear resistance; ③ Good acid resistance; ④ Good seismic stability; ⑤ Good corrosion resistance (CO, Cl2, SO2, HCl, alkali metal vapor, etc.) ⑥Good workability (unshaped); ⑦Good heat and heat insulation.

Abubuwan ƙonawa daban -daban, sassa daban -daban na amfani, da yanayin zafin aiki daban -daban, shawarwarin zaɓin masu zuwa don tunani ne kawai:

Zazzabi mai aiki na rufin, bangon gefen da mai ƙona ɗakin ƙonewa shine 1000-1400 ℃, ana iya amfani da manyan tubalin alumina da tubalin yumɓu tare da raguwar 1750-1790 ℃, kuma robobi tare da raguwar 1750-1790 ℃ iya kuma a yi amfani. .

Ana amfani da babba, tsakiya, da ƙananan ɓangarorin ginshiƙi a zazzabi na 1000-1200 ° C, ana iya amfani da tubalin carbide na silicon ko tubalin yumɓu tare da raguwar 1710-1750 ° C, kuma ana iya amfani da katanga masu jurewa. amfani;

Zazzabin sabis na rufin da bangon gefe na ɗakin konewa na biyu shine 800-1000 ℃, kuma ana iya amfani da tubalin yumɓu ko yumɓun yumɓu tare da ƙanƙantar da kai ƙasa da 1750 ℃;

Ana amfani da bangon saman da gefen ɗakin musayar zafi, kuma saman, bangon gefen, da kasan ɗakin feshin ana amfani da su a zazzabi ƙasa da 600 ° C. Ana iya amfani da tubalin yumɓu ko yumɓun yumɓu tare da ƙanƙantar da kai sama da 1710 ° C;

Daidaita yawan amfani da zazzabi da kumburi zuwa 600 ° C, kuma zaɓi tubalin yumɓu ko ƙwallan yumɓu tare da raguwar ƙasa da 1670 ° C.

Zaɓin kayan ƙyama don masu ƙonawa na sama yakamata ya dogara da takamaiman yanayi. Yakamata a ƙaddara nau’ikan masu ƙonawa ta yanayi mafi tsananin buƙata yayin aikin kayan aiki tare da abubuwa daban -daban.
