Magnesia carbon brick has excellent slag corrosion resistance, spalling resistance, high temperature strength higher characteristic, can greatly improve the service life of converter, electric furnace and ladle. It is widely used in the converter, electric furnace, refining ladle metallurgy equipment, etc.
making process. MgO-C refractories are used in slag line of L.D. converter, electric arc furnace. secondary refining furnace and ladle for pouring. Zr02-C has its limited use only in tundish, shroud and stopper for continuous casting of steel. In different processes, different atmospheres varying in partial gaseous pressures prevail thereby

Ladle refractories are divided into working lining and insulating lining, ladle refractories can be chosen according to different steel smelting process and composition of steel slag, such as use integrally casting for normal steel ladle; use MgO - C brick for refining ladle; use carbon-free ladle brick for low-carbon steel smelting.
EAF linings that are in direct contact with the molten metal and slag. Mag-carbon EAF brick are selected based on the design of the furnace, their place of use in the furnace, and the operating condi. EAF Ladle Converter MgO C Brick Magnesia Carbon Brick AMC Brick
Magnesia carbon brick has excellent corrosion resistance together with good thermal shock properties. Magnesia carbon brick offers good oxidation resistance due to use of high purity flake graphite. Application: Magnesia carbon brick is widely used in Electric Arc Furnace sidewalls, converters, hotspots and coldspots, and ladle furnace slag lines.
The influence of V 2 O 3, FeO, TiO 2, MnO and MgO in vanadium slag on the corrosion mechanism of MgO-C bricks was studied by stationary immersion tests at vanadium-extracting temperature. Experimental results show that FeO, TiO 2, and MnO could enhance the corrosion rate and V 2 O 3 and MgO could decrease it.
Magnesia Carbon Brick for Converter. Magnesia carbon brick for convertor is made adopting fused magnesite, high carbon graphite as principal raw material, mixed with antioxidant, use phenolic resin as binding agent, pressed with high pressure.
DEVELOPMENT OF HIGH FRACTURE ENERGY MgO-C BRICKS AND APPLICATIONS TO SCRAP IMPACT ZONE AND BOTTOM TUYERE OF CONVERTER* Ryoma Fujiyoshi1 Masakazu Iida2 Atsuhisa Iida3 Atushi Torigoe4 Abstract In this article, the technologies of highly durable MgO-C bricks for the scrap impact zone and bottom blowing tuyere of converters are demonstrated.
Quality Steel Plants Refractory manufacturers & exporter - buy Mgo-C Magnesite Carbon Brick, High Temperature Refractory Fire Bricks Anti Oxidant from China manufacturer.
The invention discloses a method for manufacturing slagging pellets by using waste magnesia carbon brick hot end. The method is implemented by smashing waste magnesia carbon brick hot end to prepare waste magnesia carbon brick powder, taking 55-75 parts of waste magnesia carbon brick powder, 8-20 parts of light roasting magnesium oxide powder, 3-15 parts of graphite and 7-15 parts of bonding
Aug 08, 2017 · Follow. What is magnesia carbon bricks manufacturing process Magnesia carbon brick is a high melting point of basic oxide oxide (melting point 2800 ℃) and difficult to be slag invasion of high
The MgO-C bricks are extensively used as lining work on different steel containers. Due to the high temperatures of the process, these refractories are subjected to severe wear and corrosion processes, principally in the area of contact with the slag.
The price of magnesia carbon brick is widely used in 1970s, and on the basis of adding MgO slag making slag making slag and slag retaining furnace in the slag, using oxygen lance to spray high pressure nitrogen, the residual slag in the furnace is spatter on the surface of the inner lining of the converter in 2 to 4min, and form the protection
A wide variety of magnesite uses options are available to you, There are 392 magnesite uses suppliers, mainly located in Asia. The top supplying countries or regions are China, India, and Vietnam, which supply 99%, 1%, and 1% of magnesite uses respectively. Magnesite uses products are most popular in Malaysia, Pakistan, and Vietnam.
(2) Orientation of future development of converter refractories The orientation of future development of converter refractories is outlined here in consideration of the business environment of the steel industry and the requirement for longer service life. Presently, most of the MgO-C bricks for converters in Japan are imported from China.
causes such as thermal loads, special attention was paid to the brick-laying work to select a brick having exactly the correct taper for Fig. 4 Automatic shotcreting apparatus Fig. 6 Change of operation, lining and repair and trend of lining life Fig. 8 MgO-C brick with metal case Fig. 7 Brick-fixing structure in the cone of BOF
It is widely used in 1970s, on the basis of adding MgO slag making slag and slag making slag in slag, using oxygen lance to spray high pressure nitrogen and splash the residual slag in the furnace on the surface of the whole converter inside the furnace in 2 - 4min, and form the furnace technology of slag protection layer.
furnace Chemical slag corrosion Thermo-mechanical stress on lining. In the early stage of the stabilization of this shop, the proposed working lining pattern of 150T steel ladles was 70% alumina (HA) bricks for the metal zone and magnesia carbon (MgO-C) in slag zone, as suggested by the technology supplier.
The excellent performance of mgo-c brick depends on the existence of carbon in the brick. In the process of use, the oxidation of carbon is easy to cause the deterioration of the product structure, so that the slag invades into the brick along the gap, corrodes MgO particles, and reduces the service life of mgo-c brick.
