Refractories Slide Gate Plate

Hom thiab cov qauv kev ua haujlwm ntawm cov zawv zawg zawv zawg: Cov zawv zawg nozzle yog tsim los ntawm sab sauv thiab qis zawv zawg daim hlau ua los ntawm cov ntaub ntawv refractory thiab cov txheej txheem tsav tsheb, thiab raug ntsia sab nraum qab ntawm lub ladle. Sab saum toj zawv zawg phaj yog tsau thiab qis zawv zawg phaj yog txav tau. Raws li hom kev ua haujlwm ntawm refractories swb rooj vag daim hlau, nws tuaj yeem muab faib ua peb pawg: 1) Linear reciprocating type: 2) Linear propelling type: 3) Rotary type. Los ntawm kev tsav lub pas nrig, cov refractories swb rooj vag phaj swb rov qab mus rau hauv txoj kab ncaj nraim. Thaum lub casting qhov nyob rau sab sauv thiab sab refractories swb rooj vag phaj cib yog staggered, lub taub hau lub taub hau yog sau nrog dej xuab zeb, thiab cov hlau ladle yuav loaded nrog hlau; Thaum lub casting qhov sib tshooj, cov dej xuab zeb ntws tawm tuaj yeem, thiab tom qab ntawd Pouring, thiab lub ncuav nrawm tuaj yeem tswj tau los ntawm qib sib tshooj ntawm qhov casting.

Cov phaj zawv zawg yog ib qho tseem ceeb uas txiav txim siab txoj haujlwm ntawm cov zawv zawg nozzle thiab ua lub luag haujlwm hauv kev tswj thiab tswj cov dej ntws ntawm cov hlau molten. Vim yog qhov rov qab sib cuag ntawm lub phaj swb nrog siab - kub molten steel (tshwj xeeb tshaj yog qhov casting qhov), qhov corrosion yog hnyav thiab cov kev siv yog hnyav. Lub refractories swb rooj vag phaj yuav tsum muaj cov khoom zoo xws li lub zog siab, corrosion tsis kam, thiab tev tsis kam. Thaum lub sij hawm pouring txheej txheem, nws yog guaranteed tias molten hlau tsis tuaj yeem los ntawm cov refractories swb rooj vag daim hlau. Lub refractories swb rooj vag phaj yuav tsum muaj cov khoom nram qab no

(1) Sliding nto flatness<0.05mm

(2) Lub zog txhua yam

(3) Muaj zog tiv taus yaig los ntawm molten steel thiab molten slag;

(4) Antioxidant zoo heev

(5) Zoo thermal shock stability.

Lub sealing kev tiv thaiv ntawm lub ladle zawv zawg nozzle yog tsuas yog nyob rau hauv kev sib txuas ntawm lub sab sauv nozzle thiab lub sab sauv swb phaj, thiab lub sab swb phaj thiab qis nozzle. Thaum lub sij hawm pouring txheej txheem, feem ntau tom qab pouring ib los yog ob lub cub tawg ntawm molten steel, lub sab swb phaj thiab ntws qhov hluav taws xob yuav tsum tau hloov thiab reassembled. Kev tiv thaiv sealing siv fiber ntau los yog av nplaum sealing pads los xyuas kom meej lub siab huv ntawm cov hlau molten thiab cov uniformity ntawm sab hauv zoo ntawm cov cam khwb cia slab.

hlawv rau hauv refractories swb rooj vag phaj

Nyob rau hauv qhov raug rho tawm aluminium carbon sliding phaj, tsis tsuas yog cov organic binder yog carbonized thiab coked thaum lub sij hawm firing, tsim ib tug carbon daim ntawv cog lus nyob rau hauv lub cib, tab sis kuj cov additives, xws li hlau silicon, tuaj yeem ua ke nrog cov pa roj carbon monoxide los tsim Sic thaum txo thiab raug rho tawm haujlwm.<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.

Kev ua haujlwm siab refractories swb rooj vag phaj

Nws yog ib qho uas tsis yog - hlawv aluminium carbon refractories swb rooj vag phaj nrog cov txheej txheem yooj yim, tus nqi qis thiab siv tau zoo. Cov khoom xyaw ntawm hom refractories swb rooj vag phaj zoo ib yam li cov refractories raug rho tawm haujlwm swb rooj vag. Nws siv raw cov ntaub ntawv xws li corundum, mullite, corundum, flake graphite, silicon carbide thiab silicon hmoov, thiab ntxiv phenolic resin raws li ib tug binder. Tom qab sib tov, molding, kho cua sov thiab mechanical processing Uas yog cov khoom tiav. Piv nrog rau cov hluav taws kub nyhiab aluminium carbon refractories swb rooj vag daim hlau, unburned refractories swb rooj vag daim hlau tsis tas yuav firing, roj immersion thiab retort tshav kub kev kho mob thaum lub sij hawm tsim, uas yooj yim rau cov txheej txheem ntau lawm, tab sis lub zog yog qis dua thiab lub porosity yog me ntsis siab dua. Kev xyaum tau ua pov thawj tias qhov tsis yog -sliding phaj muaj cov txiaj ntsig zoo thaum siv rau ntawm cov ladles ntawm nruab nrab- cov converters loj thiab hluav taws xob rauv taws, thiab qee qhov tseem tshaj cov roj hlawv- raus zawv zawg phaj.

Yuav ua li cas rau nruab thiab siv refractories swb rooj vag daim hlau

Tus nqi thiab hardness ntawm cov av nplaum hluav taws kub nruab nrab ntawm lub phaj swb thiab lub nozzle yuav tsum tsim nyog los ua kom cov sib koom ua ke thiab lub zog tsim nyog los ua kom tus kheej - qhib tus nqi ntawm lub nozzle, tsis txhob muaj cov pa oxygen hlawv thiab tso dej, txo cov oxidation ntawm cov phaj swb thiab qhov nthuav dav kom tiv thaiv lub nozzle ntawm "tig" thaum cov hlau molten yog nchuav. Qhov tshwm sim ntawm "slagging" tshwm sim yuav tsum tau txo kom txo tau qhov yaig ntawm slag ntawm zawv zawg phaj nto. Thaum tswj kev khiav ntawm nruam nruam steel thiab kaw lub lag luam tom qab pouring, lub stroke 1 yuav tsum tau txais kev cawmdim los ntawm tshuab pa oxygen kom tshem tawm cov seem hlau thiab tiv thaiv cov seem hlau los ntawm kev ua tsis zoo thiab ua rau ntau heev expansion ntawm zawv zawg phaj.
