Kodi mungasankhe bwanji zinthu zopangira zida zowotchera zinyalala?

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.

Zowotchera moto wamba zimaphatikizapo zida zowotchera moto, zotenthetsera kabati, makina oyatsa moto a CAO, oyatsira mabedi amadzimadzi, ndi oyatsira moto oyatsira moto. Zida zopangira zida zowotchera zinyalala zili ndi izi:

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.

Zowotchera mosiyanasiyana, magawo osiyanasiyana ogwiritsira ntchito, ndi kutentha kosiyanasiyana kwa magwiridwe antchito, malingaliro otsatirawa ndi oti angotchulidwa kokha:

Kutentha kogwira ntchito padenga, pamakoma ammbali ndi chowotchera chipinda choyaka moto ndi 1000-1400 ℃, njerwa zapamwamba za alumina ndi njerwa zadothi zokhala ndi mawonekedwe a 1750-1790 ℃ atha kugwiritsidwa ntchito, ndipo mapulasitiki okhala ndi Refractoriness wa 1750-1790 ℃ amatha kugwiritsanso ntchito. ；

Mbali zakumtunda, zapakatikati, ndi zotsika za kabati zimagwiritsidwa ntchito pamoto wa 1000-1200 ° C, njerwa za silicon carbide kapena njerwa zadothi zokhala ndi mawonekedwe a 1710-1750 ° C atha kugwiritsidwa ntchito, komanso zida zosavala kugwiritsidwa ntchito;

Kutentha kwantchito padenga ndi pamakoma am’mbali mwa chipinda chachiwiri choyaka moto ndi 800-1000 ℃, ndipo njerwa zadongo kapena zida zadothi zokhala ndi zotsika zotsika kuposa 1750 ℃ ​​zitha kugwiritsidwa ntchito;

Khoma lakumtunda ndi kumtunda kwa chipinda chosinthira kutentha, ndipo pamwamba, pamakoma ammbali, ndi pansi pa chipinda chopopera chimagwiritsidwa ntchito pamlingo wotsika kuposa 600 ° C. Njerwa zadothi kapena zomata zadothi zokhala ndi mawonekedwe obwezeretsa pansi kuposa 1710 ° C zitha kugwiritsidwa ntchito;

Sinthani kutentha kwa flue ndi flue mpaka 600 ° C, ndikusankha njerwa zadothi kapena zomata zadothi zosanja poyerekeza ndi 1670 ° C.

Kusankhidwa kwa zida zotsukira kwa omwe ali pamwambapa kuyenera kutengera zochitika zina. Mitundu yosayatsa moto iyenera kutsimikizika ndi mikhalidwe yovuta kwambiri pazida za zida kuphatikiza zinthu zosiyanasiyana.
