Khoom Description

phom lojtseem hu ua gunning mix. Nws muaj npe nyob rau hauv txoj kev installation. Cov phom txau yog siv thaum lub sijhawm teeb tsa. Thickness ntawm cov khoom rau lub cub tawg sab phab ntsa yog feem ntau tshaj 5 hli.

Khoom siv: Siv siab purity Magnesite ua cov khoom tseem ceeb, khi tus neeg sawv cev, dej txo tus neeg sawv cev thiab lwm yam ntxiv. Rau reheating rauv, siab alumina phom loj yog thov nrog siab alumina bauxite li raw khoom.

Daim Ntawv Thov: Kho rau tundish ua hauj lwm hauv ob sab phlu; kho loj rau oxygen converter, Hluav taws xob Arc rauv thiab refining rauv; sab phab ntsa ntawm reheating rauv

Phom phom lojCov khoom

Zoo tsis kam mus rau hlau nkag thiab tawm tsam los ntawm yooj yim slag

Tsawg rebound rau gunning kub kho los ntawm pneumatic conveying khoom

High refractoriness, ruaj khov ntim, abrasive kuj thiab siab thermal conductivity

Monolithic refractories yog hais txog unshaped refractories. Nws tuaj yeem ua molded lossis tuaj yeem muab cov duab raws li qhov xav tau.

Monolithics muaj graded refractory aggregates, binding tus neeg sawv cev, fillers & tshwj xeeb additives rau kev hloov kho cov khoom.

Aggregates ntawm monolithic refractories feem ntau muaj xws li kaolin flint, siab alumina bauxite, tabular alumina, dawb fused alumina, ntom mullite, tuag burnt magnesite thiab lwm yam. Aggregates yog cov ntsiab lus tseem ceeb ntawm monolithic, lawv yog tov raws li tej proportions nyob rau hauv txawv particle loj.

Properties of monolithic refractories generally including chemical composition, bulk density, cold crushing strength after 110℃drying and hot crushing strength, cold rupture strength after drying and hot rupture strength, refractoriness under load 0.2 MPa etc.

Cov Khoom Zoo

Cov phom loj muaj ntau yam ntxwv thiab qhov zoo uas cov khoom siv refractory tsis muaj. Ua ntej tshaj plaws, cov khoom siv refractory no tuaj yeem txau rau saum npoo ntawm cov khoom uas xav tau kev saib xyuas lossis kev tiv thaiv, kom ua tiav lub hom phiaj ntawm kev saib xyuas sai thiab kev tiv thaiv, thiab muaj qhov zoo ntawm kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig. Thib ob, cov khoom siv phom phom refractory muaj qhov zoo ntawm lub zog siab, kub tsis kam, kab tsis kam, corrosion kuj, thiab lwm yam tom qab tsim, thiab muaj lub neej ua haujlwm ntev.
