Spent Magnesia-Carbon Refractory Bricks from Steel

Spent Magnesia-Carbon Refractory Bricks from Steel

The sinter magnesia (min. 98 wt.% MgO; = 0 – 5 mm) is the base of the MC 98/10 brick. Magnesia is combined with the organic bond which after burning creates approx. 9.5 wt.% of C. The tests were implemented with new and spent MC 98/10 refractory bricks coming from the lining of the steel ladle (after 95 runs of the casting)

Magnesia carbon bricks (Mag carbon bricks) are made from high melting point basic magnesium oxide, high melting carbon which is difficult to be embellish by the slag and a variety of non oxide additives, making non carbonaceous composite magnesia carbon refractory bricks by combining with carbonaceous binder. As composite refractories, magnesia (mag) carbon bricks effectively make the

Jan 20, 2020 Jan 20, 2020 It can be assumed that this material is representative of scrap magnesia-carbon materials from other steelworks. To produce a recycled material from the spent bricks, the penetrated layers were cut and the unreacted parts were crushed; due to the presence of carbon in these spent bricks, the material was subjected to additional thermal treatment

The periclase-carbon bricks are produced from fused magnesia or clinker, containing about 98 wt. % of MgO. To achieve a high density of the MC material, the mass is combined from several size fractions of MgO, mostly under 5 mm. The MgO particles are bound with carbon which is formed during the carbonisation of pitch with graphite
