Mumamiriro eindasitiri ematanho ekupisa uye pombi dzemapaipi, tembiricha yakakwira yakaita se "gomo remoto" - zvinhu zvemidziyo zvinoda kumira kugocha kwenguva refu pamusoro pe800 ℃, ukuwo ichiramba kukukurwa kwemagasi ane oxidizing uye kunyange gasi ane acidic. Zvigadzirwa zvesimbi zvechinyakare zvinowanzopfava uye deformation munzvimbo ino, zvichikonzera kudzikira kamwe kamwe kwehupenyu. Zvisinei,iyo square beam roller tsvimbo yakagadzirwa nesilicon carbide (SiC)zvinhu zvakaita se "high-temperature fighter", ichitsamira pane yayo yekuzvarwa kupisa gene, ichiva "sea anchor" yekushanda kwakadzikama kweakanyanya kupisa.
Chikonzero nei silicon carbide square beam rollers inogona kuve "ace player" mumunda wekupisa wepamusoro imhaka yezvakasarudzika zvinhu:
1. Gadzira wega "thermal barrier"
Kana tembiricha yadarika 1200 ℃, dense silicon dioxide (SiO ₂) oxide firimu inongoerekana yaumba pamusoro pesilicon carbide. Iyi dhizaini ye "transparent nhumbi dzokurwa" haingogone chete kusiyanisa yakananga tembiricha yakakwira pane substrate, asi zvakare kuramba kupinda kwemagasi ane acidic, kuwana "dziviriro mbiri kubva kune yakanyanya kupisa ngura".
2. Kupisa kunowedzera, kunowedzera kusimba
Kupesana nehunhu hwezvinhu zvesimbi zvinova zvakapfava kana zvave kupiswa, silicon carbide haingochengetedze simba rayo rekukotama mutembiricha yepamusoro ye800 ℃ -1350 ℃, asi inoratidzawo kumwe kukwidziridzwa. Izvi "zvichipesana nemaitiro" maitiro emuviri anobvumira roller bar kuti irambe yakasimba munzvimbo dzekupisa, kudzivirira kuparara kwechimiro kunokonzerwa nekupfava.
3. Thermal "teleportation master"
Thermal conductivity yesilicon carbide yakapetwa kana yesimbi, iyo inogona kukurumidza uye zvakaenzana kuparadzira kupisa kwenzvimbo se "thermal highway", kudzivirira kuunganidza "nzvimbo dzinopisa" muchoto. Ichi chimiro hachingodziviriri roller pachayo, asi zvakare inochengetedza kugadzikana kweiyo desulfurization reaction tembiricha, kuvandudza kushanda kwese.
Akazvarirwa maindasitiri epamusoro-tembiricha mamiriro
Iyo yakanyanya kupisa tembiricha yesilicon carbide square beam rollers inoita kuti ive yakanyanya kunaka mumamiriro ekupisa-kupisa desulfurization senge thermal power boilers, simbi sintering, uye kuputika kwemakemikari. Mushure mekutora chikamu ichi, mabhizinesi anogona kudzikisa zvakanyanya kuwanda kwekudzika-tembiricha kudzima uye kugadzirisa, uku achiwedzera hupenyu hwesevhisi yemidziyo kusvika kanoverengeka iyo yezvigadzirwa zvechinyakare, zvechokwadi kuwana "tembiricha yepamusoro pasina kudzima, kuchengetedza kwezvakatipoteredza pasina kutonhora pasi".
Sebhizimusi rekutanga rinonyanya kutsvagisa nekuvandudzwa kwesilicon carbide ceramic zvinhu, isu tinonyatsoziva marwadzo emidziyo pasi pemamiriro ekushanda akanyanya. Yese silicon carbide square beam roller inomiririra yekupedzisira kuongororwa kwesainzi yemidziyo. Mune ramangwana, isu ticharamba takatarisa pane "yepamusoro tembiricha kuramba" seyakanyanya kutungamira nzira, uye kushandisa simba retekinoroji kuchengetedza tambo yekudzivirira yakasvibira yekugadzirwa kwemaindasitiri.
