      As an influential and responsible supplier, we are able to provide our customers with more thoughtful services and technical support. Our carbon block products have strong presence in world market, which enjoys very good reputation.

【Carbon Block】

     Carbon block is a kind of carbonaceous refractory material made from coke, anthracite or graphite and tar as raw materials after being mixed and shaped, and burned to 1450℃ in reducing flame. The carbon mass fraction is 88% to 90%. It can resist the erosion of molten metal and various slag, but it is easy to be oxidized. It’s used for masonry bottom and hearth of blast furnace.

【Application Field of Carbon Block】

     Carbon blocks are not only widely used in the metallurgical industry, but also in aluminum electrolytic cells. In addition, it is widely used in pickling tanks and electroplating tanks in the electroplating industry, dissolution tanks in the paper industry, reaction tanks and storage tanks in the chemical industry, furnaces (or equipment lining) in the ferroalloy industry, and smelting non-ferrous metals (such as aluminum and lead) , Tin, etc.).

【Semi-graphite Carbon Block Specification】

    Bulk Density:                ≥1.50 g/cm3
    Apparent Porosity:           ≤18%
    Compressive Strength:        ≥30Mpa
    Bending Strength:            ≥7.8Mpa
    Ash:                         ≥8%
    Thermal Conductivity(800 ℃) ≥7w/(m-k)

【Our Advantages of Rongxing Carbon Block】

    1, Can be customized according to customer needs.

    2, Strong thermal conductivity and electrical conductivity; high temperature resistance, good wear resistance;

    3, The introduction of the German automatic vibration forming machine which is the world's professional blast furnace carbon brick production equipment.

    4, Having full range of carbon block products with sufficient inventory.


【Special Note for Carbon Block】

     Carbon block has good thermal stability, small coefficient of thermal expansion, high temperature resistance, resistance to various acids, alkalis, salts and organic solvents, but it is easily oxidized in an oxidizing atmosphere.

Rongxing holds itself to the highest quality standards that control everything from incoming raw materials to final factory production. At Rongxing, all materials are tested to ensure they meet industry standards before entering the manufacturing phase.

Our graphite electrode products have strict consumption control, low resistivity, low ash content, high temperature strength, low thermal expansion coefficient, good thermal conductivity and electrical conductivity, compact structure, high oxidation resistance, high mechanical stability and other significant advantages. Its content of UHP needle coke is up to 80%. The UHP graphite electrodes suit the operating conditions of modern arc furnaces and those main properties are of decisive importance for obtaining economical consumption rates.

Our experienced engineers offer an all-round support to the customers for taking our UHP electrodes into operation.They check and analyse the customers’ furnace conditions in order to achieve an optimal performance of the graphite electrodes and a decrease of the specific electrode consumption. Beyond the standard procedure of selling electrodes, such as signing contracts, providing third-party testing and regular after-sales service, we support customer in many ways. This includes signing warranty agreement, ensuring the product using effect, identifying a problem before it happens and solving the problem to relieve customers of worries.

Beyond the standard procedure of selling products, we help the customer in many ways. Depending on customer requirements, the company offers services including: application-engineering consulting, selection of materials, field supervisors, and much more. This includes identifying a problem before it happens, increasing productivity, training employees on the job, and solving any problems the customer may have at that time. We offer many services including performance analysis, storage in our warehouses, inspection of accessories, and monitoring the furnace.

Rongxing Group to establish overseas offices and establish overseas warehousing; Providing warehousing, distribution and after-sales services to local customers. The scope of distribution can cover multiple countries and neighboring countries without any restrictions.
