Our products

Product category: Grey cast iron

Gas Calcined anthracite ( carbon additive )

Carbon Additive/Carbon Raiser is also called "Calcined Anthracite Coal",or "Gas Calcined Anthracite Coal".

The main raw material is Ningxia unique high quality anthracite, with characteristic of low ash and low sulfur. Carbon additive has two main uses, namely as the fuel and additive. When being used as the carbon additive of steel-smelting, and casting, the fixed carbon may achieve above 95%.

Best quality Anthracite as raw materials through high temperature calcined at over 2000  by the DC electric calciner with results in eliminating the moisture and volatile matter from Anthracite efficiently, improving the density and the electric conductivity and strengthening the mechanical strength and anti-oxidation, It has good characteristics with low ash, low resistivity, low carbon and high density. It is the best material for high quality carbon products, it is used as carbon additive in steel industry or fuel.


Calcined Anthracite Coal/Carbon Additive may substitute massively refinery coke or the stone grinds. Meanwhile its cost is much less than the refinery coke and the stone grinds. Carbon Additive may also use as the fuel It may substitute burnt carbon massively.  

Calcined Anthracite is produced when Anthracite is calcined under the temperature of 1240  in vertical shaft furnaces.Calcined Anthracite is mainly used in electric steel ovens, water filtering, rust removal in shipbuilding and production of carbon material

Calcium aluminate

A key feature for successful ladle metallurgy is slag control. 
The Calcium Aluminate has good sulphur retention and performs effectively as a desulpheric slag.
Calcium Aluminate contains no fluorine compounds, thus avoiding refractory attack and atmospheric pollution. Calcium Aluminate is the best substitute for Calcium Fluoride.
Calcium Aluminate is an excellent cover slag for the prevention of gaseous pick-up from the atmosphere and is an effective fluid sink that absorbs inclusions from steel.

About us

Company portrait

UNITED CO., LTD is a joint-stock business establishment integrated with producting, marking, technical services and information services with eligibility for conducting import and export business independently.

We are in production of Graphite electrodes (30000MT per Year), Carbon Additive(30000MT per Year), Calcium Aluminate(40000MT per Year).

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 supplying100-700mm 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.

It has UNITED’s target “to attach great importance to product quality and to creating a renowned enterprise”. We extend the warm welcome to both the home and the overseas counterparts to visit and to conduct business talks with us, seeking the possibility for cooperation for mutual development.
