Classification and production methods of ama-refractories angasindi

Kulesi sihloko, abakhiqizi bezitini ze-Henan bafuna ukukhuluma nawe mayelana nokuhlukaniswa nezindlela zokukhiqiza ama-refractories angasindi. Lightweight refractories refer to refractories with high porosity, low bulk density and low thermal conductivity. Lightweight refractories have a porous structure (the porosity is generally 40-85%) and high thermal insulation.

Ziningi izindlela zokuhlukanisa ama-refractories angasindi

1. Classified by volume density. Lightweight bricks with a bulk density of 0.4~1.3g/cm~2 and ultralight bricks with a bulk density of less than 0.4g/cm~2.

2. Ihlukaniswa ngokwezinga lokushisa lokusebenza. Ukushisa kwesicelo 600～900℃ kuyimpahla yokushisa ephansi yokushisa; I-900～1200℃ iyimpahla yokushisa ephakathi nendawo; ngaphezu kwe-1200 ℃ yimpahla yokushisa ephezulu yokushisa.

3. Ihlukaniswa ngokuma komkhiqizo. Enye yakha izitini eziphikisayo ezingasindi, okuhlanganisa ubumba, i-alumina ephezulu, i-silica nezinye izitini ezihlanzekile ze-oxide ezingasindi; enye iyinto engabunjiwe ye-lightweight refractory, njengokhonkolo okhanyelayo ongasindi.

The heat storage loss and heat dissipation loss on the surface of the industrial kiln body generally account for 24 to 45% of the fuel consumption. The use of lightweight bricks with low thermal conductivity and small heat capacity as the structural material of the furnace body can save fuel consumption; at the same time, due to the furnace It can be heated and cooled quickly, improves the production efficiency of the equipment, reduces the weight of the furnace body, simplifies the structure of the kiln body, improves the product quality, reduces the environmental temperature, and improves the working conditions.

Ukungalungi kwama-refractories angasindi yi-porosity enkulu, isakhiwo esixekethile kanye nokumelana ne-slag embi. I-slag ingena ngokushesha kuma-pores esitini, ibangele ukubola, futhi ayikwazi ukusetshenziswa ngokuqondile ngokuthintana ne-slag encibilikisiwe kanye nensimbi ewuketshezi; inamandla aphansi emishini, ukumelana nokungagugi kahle, kanye nokungaqini kahle kokushisa. Ayikwazi ukusetshenziselwa izakhiwo ezithwala imithwalo, futhi ayikwazi ukusetshenziselwa ukuthintana nezinto zomlilo kanye nokugqoka okunzima. Yendawo.

Ngenxa yokushiyeka okukhulunywe ngenhla kwezinto eziphikisayo ezingasindi, izingxenye zeziko lezezimboni ezixhumene nokushajwa, umoya oshisayo uthwala i-slag, ukugeleza okukhulu, nezingxenye ezinokudlidliza komshini okuphezulu ngokuvamile azisetshenziswa. Ama-refractories angasindi avame ukusetshenziswa njengokugcina ukushisa noma izinto zokulondoloza ukushisa eziko.
