Full-truck delivery is recommended.

Double-layer or multi-layer packaging helps prevent package damage during transportation.

Six key factors: competitive price, high quality, good payment terms, short delivery time, fast communication, and professional service.

Lower resistance may affect strength. Volatile matter that is too high can cause under-baking, while too low can cause over-baking. Low ash may also affect resistance heat. Electrode paste parameters must be matched to actual furnace conditions; good performance depends on the engineering capability of the manufacturer.

Caking does not affect the final using effect, but it increases the difficulty of feeding electrode paste. Therefore, caking should be avoided as much as possible during storage and handling.

Cylindrical paste transfers its own weight fully to the bottom of the electrode shell, unlike small blocks or egg-shaped paste. This helps form higher density and strength after baking. It also solves paste-hanging problems in DC furnaces, so cylindrical electrode paste is strongly recommended for DC furnaces.

Frequent shutdowns require electrode paste with better thermal shock resistance. Poor thermal shock resistance can cause electrode tip loss or breakage during heating. Peak-shaving production requires higher-quality electrode paste than continuous operation, including larger residual anode blocks, more electrically calcined coal, and more graphite powder.

Freezing of cylindrical electrode paste in Russia was mainly related to the old water-cooling process, where moisture entered the cylinder during cooling. Our current process uses natural drying, so the electrode paste no longer contains water.

Compared with domestic chrome ore smelting, this type of burden makes the molten iron more fluid and increases electrode erosion. Therefore, the electrode needs better oxidation resistance, and the electrode paste formula should be adjusted accordingly.
