Description for Magnesia Carbon Bricks. Magnesia Carbon Bricks as a kind of composite refractory material can take advantage of magnesite''s feature of strong resistance to slag erosion and carbon''s high thermal conductivity and low expansibility efficiently, which give a solution to handle magnesite''s weak of spalling resistance.
Description for Magnesia Carbon Bricks. Magnesia Carbon Brick, a kind of unburned carbon composite refractory, are manufactured with magnesium oxide of alkaline oxide with highmeltingpoint (2800℃) and carbon material with high melting point that is difficult to be eroded by furnace slag as the raw materials, and added all kinds of nonoxides additive and carbon binding agent.

Refractory recycling outlook There is no doubt that refractory recycling is going to see an increase in attention and activity. Owing to the potential large volumes of refractories for recycling and the fact that end users and refractory manufacturers are unlikely to invest in z Fig. 2: Refractory .
Magnesiacarbon (MgOC) refractories are used in the steel industry, where, after their life cycle, they are replaced by new ones. Consequently, a large amount of spent MgOC is p
MgOC (magnesiacarbon) refractory bricks are widely used in steel industry, the primary consumer of refractory linings, such as basic oxygen furnaces, electric arc furnaces, and ladle furnaces. The steelmaking requires extreme chemical, thermal and mechanical conditions that demand a high performance of materials, able to withstand the action ...
lack of understanding of the economics associated with refractory recycling in the nonferrous industry contributes to most users landfilling rather than recycling because recycling processes are not perceived as adding economic benefit. The factors impacting refractory recycling are .

spent refractory applications may require a strong technical background, a team approach and company commitments. This paper will emphasize the importance of a technical background and a team approach to recycling. MgO+C and MgO are widely used refractory materials in the EAF. The low value of the spent refractories makes them difficult to recycle.

Apr 11, 2017· The goal of the project was to recycle 50% of the residual waste generated (approximately 2,700 tons out of a yearly new consumption of 10,000 tons). This residual waste mainly consists of bricks from the demolition of Ladles, Furnaces and Tundishes. These wastes were classified into 3 groups: MagnesiaCarbon, High Alumina and Other Grades.
Magnesiacarbon (MgOC) bricks have been among the first refractory bricks to be recycled since the mid90s (Arlt and König, 1998). The working lining of EAF are almost entirely composed of MgOC bricks, with only a small quantity of AluminaMgOC (AMC) bricks present at the bottom. ... Other threats to refractory recycling are lack of clarity ...
