Electric arc furnace is a kind of electric furnace that utilizes electric arc energy to smelt metal. Industrial application of electric arc furnace can be divided into three categories: the first category is direct heating type, the arc occurs in the special electrode rod and be melted between the charge, the charge is directly subjected […]

With the development of new dry-process cement production technology, the corresponding refractory materials have also made great progress. In addition to the conventional refractory bricks have a breakthrough, the performance of refractory castables is also more and more perfect, and widely used in the kiln in the amorphous parts. As we all know, refractory castable

The traditional medium frequency furnace lining material has three kinds, one is acidic furnace lining, by quartz sand dry pounding molding, binder for borax or boric acid; another is magnesium sand dry pounding molding, binder is also borax or boric acid. The last one is neutral furnace lining, pounding molding by high alumina bauxite clinker.

As a indispensable refractory material, its strength characteristics are directly related to their quality and use of effectiveness. In many industrial fields, such as metallurgical, cement production, glass manufacturing and chemical industry, pouring materials played a pivotal role. Therefore, the research and development of high -performance watering is particularly important. It is especially worth mentioning

Different recarburizers have different qualities. For example, there are graphite recarburizers and coal-based recarburizers. Although they are all recarburizers, they are different in basic characteristics, absorption coefficients, prices, advantages and disadvantages, etc. It is not very large, but if it is not used properly, it will also affect their recarburization effect. 1.The raw materials of

Common insulation materials for tundish The refractory materials of the tundish include permanent layer castables, working layer dry materials, nozzles and seat bricks, slag retaining wall series and continuous casting. The permanent layer is between the working layer and the tundish shell, and is not in direct contact with the molten steel and slag. It

1.Causes of cracks in high alumina brick molding and improvement measures High-alumina bricks are usually formed by friction presses or automatic brick presses of more than 300T. The biggest feature of cracks caused by reasons such as product brick shape, forming mold, uneven distribution, operation and pressure is strong regularity, and the depth, position and

The masonry of high-temperature industrial kilns is inseparable from refractory bricks. In the actual refractory brick masonry process, it must be operated by experienced and qualified construction personnel to ensure the quality and safety of the masonry. What construction specifications should be followed in the actual construction process to ensure the overall quality requirements? The

Alumina magnesia carbon (AMC) bricks are widely used in various high-temperature applications, such as in the iron and steel industry. Here are some advantages and disadvantages of using AMC bricks. Advantages of alumina magnesia carbon bricks: High Refractoriness: Alumina magnesia carbon (AMC) bricks have excellent refractoriness, which makes them suitable for use in high-temperature applications
