Refractories——Corundum

Corundum is one of the most important refractory raw materials, the use of corundum refractory products manufactured in aluminum MgO-C ladle, ladle prefabricated blocks, torpedo and other industries are widely used. Now, with the continuous development of high-temperature industrial technology, constantly upgrading equipment,

innovative theories, especially the application of new technologies in recent years, the metallurgical industry, more to promote the adjustment of product structure refractories, corundum in refractories use the proportion is growing.

In recent years, large and small manufacturers continue to rise corundum, production quality is uneven, use, corundum refractories produced in various industrial applications, there are various problems chalking bursting. The main problem is exposed high levels of impurities corundum, alumina content but related issues.

High impurity content of corundum,products will cave in there, it will affect the quality of subsequent products. The low alumina content intolerance can lead to corrosion of the products. Meanwhile corundum powder particles cause problems exposed cracks in the production of products, the bursting of the situation.

Corundum products because of non-compliance on the one hand a small production companies for lower prices deliberately low-quality goods, on the other hand there are the production and use of business-to-business product parameters sufficient reason Communication Department. Luoyang Yilong Refractory Co.Ltd help customers understand their requirements through the use of sales, specifications, parameters and other conditions, the concept of vague answer your technical staff is also actively through the exchange and technical visits with customers to fully understand customer intent determining product specific parameters. At the same strict quality control in the production process. Produced corundum product quality, stable performance. welcome to consult and order.

Refractories industry must keep pace with the times

This year my Refractory Factory (LuoyangYilong) circumstances, can determine the continuation of the current domestic refractories shipping price trend appeared, although the release of last year's major banks invariably loose interest, but also very difficult budget period a substantial profit. Restructuring of production and sales model, to enhance the industry credit, reduce transaction costs,

have become big businesses refractories, refractory materials prices continue to drop further at present, and slightly expanded, in the absence of sufficient growth in demand, the refractory plant continue to cut prices to sell .

The current situation is, wages rise refractory factory, is the rapid growth of the financial costs, the price index of refractory products continue downward. Also facing a more serious problem is the decline in profits, negative factors such as high-end equipment imported condescending is the most important factor in the refractory industry is facing difficulties. Imbalance between supply and demand, the industry must adjust the strategy, innovation, has become a trend, at this time, online marketing strategy has been quietly probe.

According to the actual circumstances of refractories, network marketing has become a trend, with the maturity of e-commerce models, online trading has become commonplace. E-commerce model system reform is not a cure-all prescription, guide enterprises in the public and individual agency reform, they should based on the principle of "seeking stability, and integrity," according to objective laws, integrity management, establish brand awareness, promote the transformation of the traditional model. Let refractories industry has to keep up with the development of the times. This is the trend, which is profitable. Internet marketing go this route, every industry needs and must be the way to go, just a matter of refractories industry is no exception.

Refractory for electric arc furnace lid

EAF uses A1203 65% -85% alumina brick masonry lid, the special needs of the site is also used tabular alumina brick (with a plate Al20390% -100%), but the price is expensive, silica brick is about 10 times higher 31V or thermal stress relief lid damaging effects of aluminum bricks, high alumina brick firing using phosphate bonded alumina bricks do not burn with white masonry made good use of effects. Some (HP) in high power electric furnace cover, the main use of high alumina bricks (about 80% Al2 03) and chemically bonded magnesia-chrome brick (Mg0> 65%, Cr2 037% _15%) Consolidated masonry furnace cover. High power (UHP) electric cover using mullite corundum brick, the brick main feature is a good thermal stability, resistance to high temperature load-deformation ability, it just to meet the requirements of the lid refractories, MK-80, No. MO corundum bricks,

is fused corundum and fused mullite particles strengthen the structure of products. 50t UHP EAF for cover, stainless steel and bearing steel smelting life increased by 25% -35% higher than magnesia-chrome brick roof.

High alumina brick lid. Alumina brick masonry furnace lid began in the late 1950s. At that time the use of high alumina brick lid (Ak 0365% -80%) increased by 4 times higher than silica brick lid life. Firing alumina bricks (A \ 2 03 80 16) and phosphate binding does not burn alumina brick (Al2 03 80% -85%) and mullite brick firing or not firing phosphate binding mullite brick, they have in common is an excellent thermal shock resistance. The life of the early 1960s, the lid has reached about 200 furnaces.
