Why is Column-Type Electrode Paste More Recommended?

When column-type electrode paste is loaded into the electrode shell, its weight is transferred directly to bottom. As a result, the electrode paste sintered under this gravitational force achieves higher density and greater strength compared to oval electrode paste or trapezoid electrode paste. This characteristic of column-type electrode paste perfectly solves the problem of paste hang-up in DC furnaces. Therefore, for DC furnaces, we strongly recommend using column-type electrode paste.

Product Q&A

Q:What electrode paste support does Rongxing provide?

Rongxing provides comprehensive technical support for the electrode paste, including:regular plant visit assessments, operator training,root cause analysis for electrode breakage, on-site resolution of issues

Q:How do you guarantee product quality?

We always provide a pre-production sample before mass production and conduct a final inspection before shipment.

Q:Middle East Customer Case: How to Solve Hearth Carbon Buildup?

Based on our experience, carbon buildup on the furnace hearth in the Middle East is mostly caused by insufficient reactivity of the reducing agent used. *To completely solve this problem, it is necessary to reduce the amount of raw coal and coke while increasing the amount of semi-coke. *Operating with high current and low voltage can temporarily reduce carbon buildup.

Q:How to Deal with the High Magnesium-Aluminum Ratio in African Chrome Ore?

Compared to ferrochrome smelting with similar furnace charge conditions in China, this type of feed material makes the hot metal thinner, resulting in greater scouring and higher oxidation resistance on the electrode. Therefore, the electrode paste formula must be adjusted.

Q:Russia Customer Case: How to Solve the Freezing Problem of Electrode Paste?

The freezing of the Russian column-type electrode paste occurred because the previous manufacturing process used water cooling, allowing moisture to enter the interior of the cylindrical electrode paste during the cooling stage. In contrast, the current process uses natural air drying, so the electrode paste no longer contains moisture.
