1,good adhesion 2,less rebound 3,easy to repair Gunning refractory for EAF is made of magnesite clinker and synthetic magnesite with special granularity distribution, and manufactured by adding composite binding agent. It has the characteristics of high adhesive rate, less resilence and easy gunning etc.It is mainly used for gunned repair of alkali steelmaking.

Classification of refractory's Magnesite Magnesite refractory's are chemically basic materials, containing at least 85 percent magnesium oxide. They are made from naturally occurring magnesite (MgC03). The properties of magnesite refractories depend on the concentration of silicate bond at the operating temperatures.

Magnesite is magnesium carbonate (MgCOs) and has a theoretical magnesia (MgC) content of 47.6 per cent. Hydromagnasite, or hydrated magnesium carbonate [Mgr(OH)z(COs )3.3H20] may contain UP to 43 per cent magnesia. Brucite, magnesium hydroxide [Mg(OH)z], contains up to about 69 per cent magnesia. Dolomite

Fused magnesite clinker is the main raw material for producing magnesia carbon bricks. Flake graphite: graphite is mainly due to its excellent physical properties: (1) the non wettability of the slag. (2) high thermal conductivity. (3) low thermal expansibility. In addition, graphite won't not fused with refractories at high temperature.

A process for mitigation of fouling deposits within a combustion zone, capturing of toxic metal emissions, and reduction of visible sulfur emissions attributable to sulfuric acid mist during coal combustion. SO 3 formed during coal combustion is reduced by the addition to the coal of raw, unprocessed magnesium-containing minerals such as magnesite ore or brucite ore.

Fused minerals have hundreds of different applications as refractory materials due to their ability to withstand continuous exposure to the combination of heat, corrosion, abrasion and impact. Choosing the proper refractory material for an application is critical because poor quality materials can lead to excessive maintenance and equipment failure – resulting in recurring …
