Metal secondary oxidation protection system
SME Vulkan-TM suggests using the principle of gas dynamic protection of metal against secondary oxidation, offering broad technical capabilities, as an alternative method of metal jet secondary oxidation protection.
SME Vulkan-TM Metal Secondary Oxidation Protection System
The metal secondary oxidation protection system is suitable both for slide gate casting (when mounted on a slide gate using a bayonet nut during inter-melting service of a steel casting ladle), and for bottom-pour ladle casting (when mounted using a special fastening ring). The system can be a part of steel continuous casting systems and can be installed on a tundish (under development).
Major advantages:
- Continuing protection during casting;
- Durability – 5-7 melts;
- Forging regrinding cost improvement by 1.25 times;
- Rejection rate down by 2.3 times;
- Defect rate down by 1.25 times;
- Patent-protected design.
