Chiedza Huremu Silica Brick 1.2

Zvidhinha zvesilika zvakapfava zvinoshandisa silika yakatsetseka seyakagadzirwa, uye saizi yavo yakakosha kazhinji haipfuure 1mm, uye zvimedu zvisingasviki 0.5mm hazvisi pasi pe90%. Zvinhu zvinopisa zvinowedzerwa kune zvigadzirwa kana gasi chizvarwa nzira inoshandiswa kugadzira porous structure, iyo inobva yadzingwa. Inogonawo kugadzirwa muzvigadzirwa zvisina kupisa. Inonyanya kushandiswa munzvimbo dzakasiyana-siyana dzehuni dzinoda kudzikamisa kana kuzvidzikisira uremu pasina kusangana zvakananga nekunyunguduka, pasina mhedzisiro yemagasi anoparadza, uye pasina kushanduka kwekushisa kamwe kamwe. Inoshandiswa pakupisa kwakanyanya uye haigone kusangana nealkaline refractory zvinhu. Zvichienderana nechinhu, tembiricha yekushandisa iri pakati pe1200 ne1550 ℃.

Zvidhinha zvesilika zvakareruka chinhu chakanyanya kukosha, chinonyanya kushandiswa muindasitiri yegirazi uye indasitiri yesimbi. Muzviitiko zvakawanda, zvidhinha zvesilika zvakareruka uye zvidhinha zvakaomeswa zvesilica zvinoshandiswa sezvikamu zvekuumbwa. Inowanzo shandiswa muindasitiri yegirazi yekubikira, kunyanya kuvharidzira kwevhavha yemoto, nekudaro kuderedza kurasikirwa kwekupisa uye kuwedzera kugona kwekunyungudika. Muindasitiri yekugadzira simbi, zvidhinha zvakareruka zvesilica zvinoshandiswa kurerusa kweanopisa kuputika madziro evira uye domes.

1. Zvidhinha zvisingaremi zvesilica zvinoshandiswa muindasitiri yegirazi - thermal insulation yevira remoto.

Mukuita kwegirazi kunyunguduka, tembiricha yakakwirira inosvika munzvimbo yakasimudzwa yakaderera yevhavha. Zvichienderana nemhando yegirazi, tembiricha inotenderera 1600 ° C. Iyo lightweight layer inowanzogadzirwa sematanho maviri kana anopfuura.

Zvidhinha zvesilika zvakareruka zvinonyanya kuoneswa kune iyi mitoro yekupisa. Zvinotarisirwa kuti iyo imwechete layer yevault (chimiro uye lightweight layer) ine yakafanana kana yakafanana yekuwedzera zvivakwa. Silika zvidhinha zvine huwandu hwakawanda hwe1250kg · m-3 kana 1000kg · m-3 inogona kusangana nezvinodiwa zvedense layer. Chikamu chinotevera chinoshandisa silica zvidhinha zvine huwandu hwakawanda hwe800Kg · m-3 kana 600kg · m-3.

Zvidhinha zvesilika zvakareruka zvinogona kuiswa zvakasununguka pavhavha yechoto kana kusungirirwa ne silica moto ivhu. Iko hakuna kemikari mutoro panguva yehupenyu hwebasa revira (makore akawanda). Zvidhinha zvesilika zvisinganzwisisiki zvinonyanya kushandiswa nokuti kemikari nemaminerari ekugadzirwa kwechigadziro chekushanda kwakafanana neiyo dense silica zvidhinha zvinoshandiswa.

2. Zvidhinha zvidhinha zvesilika zvinoshandiswa muindasitiri yesimbi - hot blast furnaces

Mafuro ekupisa anopisa anowanzo shandiswa kumhepo inopisa (inonzi blast furnace blast), iyo yakabatana nemhepo yekupisa yemoto unoputika. Zvichienderana nechimiro uye nzvimbo yevira rinopisa, tembiricha iri pakati pe1000 ne1300 ° C, uye mhepo inopisa iri pakati pe2300 kusvika 6500 m3 · min-1.

Izvi zvinoda kuverenga kuenzanisa pakati pehuni inopisa inopisa (yakasiyana-siyana yezvikamu uye nzvimbo dzekushandisa) uye girazi remoto dome pamatanho akasiyana uye mitoro yakasiyana-siyana, inotarisa pane thermomechanical properties. Kune iyo lightweight layer, vhoriyamu density inoshandiswa ndeye 1250kg·m-3 kana 1050kg·m-3 (kunyanya nekuda kwesimba radzo repamusoro)
