Features

Kaolin ulu, Ya sanya daga tsaurin alumina, wanda dogara ne a kan ma'adini yashi. A wani musamman tama-smelting makera ne narke a zazzabi na 1800 digiri. A narkewa zone gabatar uku wayoyin, yayin da a shafin na tsara su ne kawai biyu. hurawa dabara da ake amfani da dab littattafai, shi dogara ne a kan tasiri na musamman tururi bayar da wani matsin lamba daga game da 0.7 MPa. Ejection bututun ƙarfe damar da nassi daga duk hurawa tsari. Kamar yadda binders iya aiki ruwa da gilashi, lãka ko sumunti.

Vata kaolin sayar a Rolls daga sama zuwa mita 10 a tsawon, kauri da nisa daga 2 cm da 60 cm, bi da bi. Shi ne m, game da shi, samar da wani snug Fit ga wani zane. Yau, masana'antun na kokarin inganta kayan da Bugu da kari na ƙarin aka gyara, misali yttria. Wannan inganta zaman lafiyar na zaruruwa da kuma fadada yin amfani da yiwuwa.

Materials resistant fire

Tsaurin kayan sanya daga ma'adinai da kwasfansu, kuma suna resistant zuwa high yanayin zafi, kuma su halaye kasance canzawa. Su ne ba makawa a karfe masana'antu domin barasan, maras tabbas, kuma sauran matakai, halittar sunadaran da high-zazzabi (Motors, reactors) da aka gyara domin su. Bayan yin amfani da refractories aka aiko domin sake amfani.

Mafi sau da yawa, irin wannan samfurin yana da wani rectangular siffar da kuma low nauyi, yin su manufa domin daban-daban rufi. A halin yanzu, akwai wani sauki raguwa a samar da refractories, kamar yadda mafi hankali ne ya biya zuwa samar da musamman rokoki da kuma concretes, resistant zuwa high yanayin zafi.

Tsaurin kayan: Manufacturing hanyoyin

kayan Bã su da wani yumbu matrix sanya na tsaurin borides, nitrides, oxides kuma suna da wani babban matakin da sunadarai inertness da karko. Kuma sau da yawa amfani da carbon fili.
