company news about HYDBE In-Furnace Refining Equipment

For products such as aerospace aluminum alloy components, aluminum strips, and aluminum foils, performance requirements are becoming increasingly stringent. In addition to ensuring their chemical composition and mechanical properties, defects such as porosity, gas holes, and inclusions are not allowed. Melt purification is a fundamental guarantee for the production of high-performance aluminum alloys, and in-furnace refining is one of the key processes in melt purification. Only by removing most harmful substances in the furnace can the requirements for high-performance aluminum alloy production be met after online processing.

To address the issues existing in current manual nozzle operations, Haide has developed an advanced in-furnace purification device, which can improve the effect of removing hydrogen, slag, and alkali metals from aluminum melt in the furnace. The new in-furnace refining technology and device, in cooperation with well-known aluminum companies, not only improve the quality of aluminum liquid and the efficiency of downstream online refining, further ensuring that the quality needs of end-users are met, but also help them improve the efficiency of in-furnace melt processing, reduce potential safety hazards and environmental pollution.

Advantages

• Bubbles are distributed throughout the melt, increasing the contact area between refining bubbles and the metal melt, prolonging the contact reaction time between gas and harmful substances, and helping to carry the gas, slag, and impurities dissolved in the metal melt out of the melt surface, resulting in high refining efficiency.
• The graphite rotor rotation is made of high-purity graphite. The structure of the rotor not only breaks bubbles but also enables uniform mixing of the aluminum melt with the refining gas sprayed from the rotor, increasing the contact area and time between bubbles and the aluminum alloy liquid, and improving the degassing and purification effect.
• The "gas + flux" combined purification process reduces the consumption of gas and refining agents, reduces smoke emissions, and improves the safety and environmental protection of the operating environment.
