The Plant of Graphite electrode has a complete producing line from material-calcining (three set ) to Extrusion (one set 3500 tons pressure, two sets 2500 tons pressure)、Impregnation (two set of vacuum impregnation)、Graphitization (two set LWG Graphitization Furnace) 、the machining process ( computer control). We are supplying Ø100-Ø700mm Graphite Electrode with specification RP, HP, SHP and UHP. Our products have been exported far to America, Japan, Europe, Africa and Southeast Asia.

The Plant of Carbon Additive has 5 set calcining furnace, and we can supply 30000MT/year with 9 of type of Carbon additive (C content from 90% to 99%). Especially our product has advantage of low sulfur、hydrogen oxygen、nitrogen content. Our products have been exported far to Europe, North and South America and Southeast Asia.

The Plant of Pre-melted Calcium Aluminate has 3 of the Gas Melting furnace, they can produce Calcium Aluminate 40000 tons per year. Especially our product has the advantage of content, low Ferro content and low melting point. Our products mainly export to Europe and Middle East.

We have already greatly penetrated in the world market, and are supplying many advantageous materials to the foreign market. We have set up friendly and stable business relation with hundreds of clients from allover the world. We are enjoying reputation with our high quality and competitive price. Honesty and promise-keeping are our religion.
