Our solution for pressure injection ensures that the pressure is always equal for both material inlet and outlet pipes. Even highly abrasive or materials with high viscosity can be fed with the required precision. The feeding valve which adjusts the material flow is of our own design, the Kopar Cupola Valve.
The pressure lance is designed to last in the most demanding environments. Made from carbon steel, it endures continuous heat and immense pressure.
If the material is molten, the feeding lance will gradually wear out. However, our engineering crew is trained to swap the feeding lance for a new one as smoothly as possible to make the production pause short.
Suitable usage cases for pressure injectors
Our pressure injection solution can be used in metallurgical processes, where sulfidic concentrates must be injected into the molten bath of the electric furnace through a submerged lance. The objective herein is to add sulfur, which decreases viscosity and lowers the liquid’s temperature and, eventually, increases metal recovery.
