Pudong new district, Shanghai, China.
refractory bricks could be improved by using pitch, tar, flake, and vein graphite minerals [22, 26, 68, and 38]. For example, multi-impregnated pitch-bonded dolomite refractory brick for ladle furnace was described by Rabahand Ewais [39]. Brick samples were prepared from a blend of calcined dolomite mineral and coal tar pitch. The blend was
Calcined dolomite is a material that plays an important role in the steel sector, both for its purifying action and for the protection of refractory linings. Calcium and magnesium oxide or calcined dolomite are obtained from dolomitic minerals such as calcium carbonate and magnesium (Ca Mg (CO3) 2, through the calcination process. Ca Mg (CO3)2 + Heat […]

MAGNA: From the Mine to the Steel Mill for 75 Years. Thursday, February 20, 2020 . As a mining and industrial company, MAGNA is dedicated to the extraction and processing of magnesite from its mines in Spain. Since 1945, MAGNA has been exploiting the magnesium deposit of Eugi (Navarra/ES), and since 2017 in Borobia (Soria/ES).
stone, dolomite, and silica are widespread throughout the world, although there are examples where an adequate flux source was not available and this affected the process selection. Limestone and Dolomite Limestone and dolomite fluxes used for ironmaking and steel- making in the United States originate primarily from Michigan.

Tarred dolomite-magnesite refractories based on preserved dolomite, finely ground magnesite, coal-tar pitch and anthracite oil, are suitable for lining steel converters with top oxygen blast.For the first time in the Soviet Union unfired tarred dolomite converter refractory has been obtained with an addition of magnesite which is not inferior in service to ordinary fired brick PSh used for ...
1. Introduction. Dolomite refractory bricks are alkaline products composed of calcined or sintered dolomite ore [Mg.Ca (CO 3) 2] mixed with resin, peck, or other additives,, .The high percentage of magnesia [40 wt%
The Dolomite sinter or Dead-burned dolomite is generally used in the refractory industry for the refractory made by firing dolomite, with or without additives, at high temperature to produce dense, well-shrunk particles. This refractory is widely used wherever steel is refined using basic slag and can stand temperatures up to 2.300ºC.
The factory also produces a wide assortment of unshaped products like mortars, mixes and fluxing agents: mixes for runners of blast furnaces, gunning mixes, ramming mixes, fireclay and basic mortars, refractory concretes, burnt lime and dolomite clinker. Portrait Dolomitkontor. This enterprise is an Austrian-Polish trading company.
Monolithic refractories. "Monolithic refractories" is a general term for refractories of granular material and clay type. There are castable refractory materials, gunning materials, patching materials, and others which can be used in various ways depending on the particular purpose. Gunning materials are mainly used to make repairs.
Within this investigation, dolomite refractory bricks were prepared by varying different additive with an intention to urge the positive PLC of the brick. It's documented that Iron Oxide could also be an honest additive for dolomite brick sintering. it is also been reported that monoclinic zirconia (m-ZrO2) additive improves the BD, CCS and PLC

In this study, the effect of alumina addition on dolomite refractory (extracted from Konya/Turkey) which has been planned to use in refractory industry was investigated. The aim of the study is to increase the brownmillerite phase which aids the sintering process of dolomite. For that purpose, 0.5 wt-% alumina powder (including 99,5% Al 2 O 3 ) was added to 3 to 6 mm fraction …
The refractory products comprise bricks based on magnesia, alumina with varying contents of silica, with possible additions of carbon or chromium oxide or other additives to create specific properties of the refractory products. Additionally, we offer the whole range of refractory castables for monolithic solutions.
Doloma (sintered dolomite) having a 0.5 wt.-% optimum mill scale content were used to form bricks with addition of resin and graphite, so that the effects of graphite was evaluated.
