Refractories Slide Gate Plak

Kalite ak prensip k ap travay nan plak glisman: Aparèy bouch glisman an konpoze de plak anwo ak pi ba glisman ki fèt ak materyèl refractory ak yon estrikti kondwi mekanik, epi li enstale deyò anba a nan louch la. Plak glisman anwo a fiks epi plak glisman pi ba a se mobil. Dapre mòd nan aksyon nan plak refractories glise pòtay, li ka divize an twa kategori: 1) kalite lineyè resipwòk: 2) kalite propelle lineyè: 3) kalite Rotary. Lè w kondwi baton an rale, plak pòtay glise refractories yo glise retounen ak lide nan yon liy dwat. Lè twou yo Distribisyon sou anwo ak pi ba refractories glise plak pòtay brik yo dekale, twou bouch anwo a plen ak sab drenaj, ak louch an asye ka chaje ak asye; lè twou yo Distribisyon sipèpoze, sab la drenaj koule soti otomatikman, ak Lè sa a, Vide, ak vitès la vide ka kontwole pa degre nan sipèpoze nan twou yo Distribisyon.

Plak la glisman se yon eleman kle ki detèmine fonksyon an nan bouch la glisman epi li jwe yon wòl nan kontwole ak reglemante koule nan asye fonn. Akòz kontak repete plak la glise ak segondè -tanperati asye fonn (espesyalman pati nan twou Distribisyon), korozyon an grav ak kondisyon yo itilize yo se piman bouk. Plak pòtay glise refractories yo oblije gen bon pwopriyete tankou gwo fòs, rezistans korozyon, ak rezistans penti kap dekale. Pandan pwosesis la vide, li asire ke asye fonn pa ka koule ant plak pòtay glise refractories yo. Plak pòtay glise refractories yo dwe gen pwopriyete sa yo

(1) glisman sifas plat<0.05mm

(2) Segondè fòs mekanik

(3) Bonjan rezistans nan ewozyon pa asye fonn ak salop fonn;

(4) Ekselan pwopriyete antioksidan

(5) Bon estabilite chòk tèmik.

Pwoteksyon an sele nan bouch la glisman louch se sitou nan koneksyon ki genyen ant bouch la anwo ak plak la glise anwo, ak plak la glise pi ba ak bouch la pi ba. Pandan pwosesis la vide, jeneralman apre yo fin vide youn oubyen de founo asye fonn, yo dwe ranplase plak glise ki pi ba a ak priz drenaj la ak reasanble. Pwoteksyon sele a sèvi ak kousinen sele fib oswa ajil pou asire gwo pwòpte asye fonn lan ak inifòmite bon jan kalite entèn plak jete a.

boule nan refractories plak pòtay glise

Nan plak la glisman kabòn aliminyòm tire, se pa sèlman lyan òganik la karbonize ak coked pandan tire a, fòme yon kosyon kabòn nan brik la, men tou, aditif yo, tankou Silisyòm metalik, ka konbine avèk kabòn nan fòme Sic lè redwi ak tire nan.<1300°C. , and a ceramic bond is formed within the brick body. Therefore, there is a dual bonding system of ceramic bonding and carbon bonding in the fired aluminum carbon sliding plate. It significantly improves the strength of the refractories slide gate plate, and even after the carbon is burned out during use, it can maintain sufficient residual strength because it is a ceramic bonding system. After the refractories slide gate plate is burned, it is usually soaked in oil. Vertical or horizontal vacuum-pressurized oil immersion devices are generally used in oil immersion. After the slide is preheated, put it into the oil immersion tank, and evacuate it to a vacuum℃of 650mmHg or above, introduce heated tar or asphalt, and pressurize the oil to 8~16kgf/cm2 or higher to make the tar or asphalt Being sucked into the open air holes of the refractories slide gate plate. The cast holes in the refractories slide gate plate can be made during molding, or they can be formed into a whole plate without holes and then drilled later. Most people think that drilling is beneficial to improve the quality of the refractories slide gate plate. In addition, wrapping and hooping the refractories slide gate plate with thin iron sheets is considered an important measure to ensure the safe use of the refractories slide gate plate. It can prevent the refractories slide gate plate from breaking during use, and because this metal hoop is wrapped very tightly, it has limitations. The propagation of cracks in materials, especially the effect of crack opening.

Segondè pèfòmans refractories plak pòtay glise

Li se yon plak ki pa -boule aliminyòm kabòn refractories glise pòtay ak pwosesis relativman senp, pri ki ba ak bon efè itilizasyon. Engredyan yo nan sa a kalite refractories plak pòtay glise yo sanble ak sa yo ki te tire refractories plak pòtay glise. Li itilize matyè premyè tankou korundon, mullite, korundon, grafit flake, karbid Silisyòm ak poud Silisyòm, epi li ajoute résine fenolik kòm yon lyan. Apre melanje, bòdi, tretman chalè ak pwosesis mekanik Sa se pwodwi a fini. Konpare ak refractories aliminyòm kabòn glise plak pòtay, plak pòtay ki pa boule refractories glise pa mande pou tire, imèsyon lwil oliv ak tretman chalè retort pandan fabrikasyon, ki senplifye pwosesis pwodiksyon an, men fòs la pi ba ak porosite a se yon ti kras pi wo. Pratike te pwouve ke plak ki pa -boule glisman an gen bon efè lè yo itilize sou louch yo nan konvètisè mwayen-gwosè ak fou elektrik, ak kèk menm depase lwil la boule-plak glisman plonje.

Ki jan yo enstale epi sèvi ak refractories plak pòtay glise

Kantite ak dite ajil dife ki genyen ant plak la glise ak bouch la ta dwe apwopriye pou fè inifòm jwenti a ak nan fòs apwopriye pou ogmante pousantaj ouvèti pwòp tèt ou -bouch la, evite boule oksijèn ak drenaj, diminye oksidasyon plak la glise ak ekspansyon twou a pou anpeche bouch la soti nan "vire" lè yo vide asye a fonn. Ensidan an nan "slagging" fenomèn yo ta dwe redwi diminye ewozyon nan salop sou sifas la glisman plak. Lè w kontwole koule asye depoze kontinyèl ak fèmen operasyon an apre vide, konjesyon serebral 1 la ta dwe sove pa mouche oksijèn pou retire asye rezidyèl la epi anpeche asye rezidyèl la pa mal opere epi sa ki lakòz twòp ekspansyon plak la glisman.
