The uneven heating problem in tubular furnaces was addressed through innovative design modifications, primarily by incorporating both radiation and convection chambers. This dual-chamber approach, inspired by box furnace designs, creates more uniform heat distribution. Additionally, advancements in high temperature heating element materials like Kanthal and silicon carbide improved heat transfer efficiency. The solution also involved optimizing furnace configurations (horizontal, vertical, split) for specific applications, ensuring better thermal management based on material movement and process requirements.
