FAQS about Electrical heat storage material magnesia iron brick

What are magnesia bricks?

Magnesia bricks refer to the basic refractories product with magnesia (MgO) as the main component (more than 90%) and periclase as the main mineral phase. According to production process, the magnesia bricks can be classified into fired magnesite brick and unfired magnesia brick.

What is high-fired Magnesia-chrome brick?

Where greater wear resistance is needed, high-fired magnesia-chrome brick, re-bonded fused magnesia-chrome grain brick can be used. These products are composed of a synthetic grain made by melting magnesia and chrome ore in an electric furnace. Then milling the cooled fused ingot into brickmaking sizes.

Why are magnesia bricks a good choice?

Magnesia bricks have relatively high refractoriness over 2000 °C, higher refractoriness under load (shown in the Table 1), excellent resistance to the chemical erosion of alkaline slag containing iron oxide, and poor thermal stability.

What are the raw materials for magnesia bricks?

The main raw materials for magnesia bricks are sintered magnesia and fused magnesia. The magnesia content of the former is 83–98%, the latter 96–99%. The magnesia with MgO content of 98–99% is high-purity magnesia. In addition to minimizing low melting point impurities, the high-purity magnesia must have higher bulk density.

What is a magnesia-carbon brick?

Mag-carbon products are designed with improved corrosion and slag resistance through the addition of graphite. When a magnesia-carbon brick is bonded with an organic resin, it is also known as resin-bonded magnesia-carbon brick. Mag-carbon bricks are used in basic oxygen converters, electric furnaces, and steel ladles.

What is magnesite-chrome & Magnesia-spine L Brick?

Magnesite-chrome and magnesite-spine l brick are blends of dead-burned magnesite with chrome ore and magnesia-alumina spinel, respectively. Dead-burned magnesite is sintered in a rotary or vertical shaft kiln. Fused Magnesia is normally manufactured in an electric arc furnace by melting at 5000°F.
