Metallurgical Diversion Chute: A Flow-Guiding Steel Structure for Continuous Casting
Category: Industry News
Time: 2026-09-28
Diversion chute is a core supporting steel structural component used in continuous casting processes for steelmaking and foundry operations. It is mainly applied to receive and evenly distribute molten steel and molten iron during production. Fabricated by welding heavy steel plates, the equipment features a robust and stable structure. As essential infrastructure, it ensures regular and stable casting operations. With reliable structural design and rigorous manufacturing processes, diversion chutes are suitable for harsh working conditions in the metallurgy industry characterized by high temperature and heavy scouring, and are widely used in various continuous molten metal casting production lines.
I. Product Structural Features
The diversion chute adopts a simple and practical overall structure, mainly consisting of an integrated steel trough body and built-in flow guide plates, featuring high rigidity and good deformation resistance. The trough body is fabricated from thickened steel plates with strong load-bearing capacity. It provides stable support for the internal refractory protective layer and effectively extends the service life of the equipment.
The fixed V-shaped triangular flow guide plates installed inside the chute serve as the core functional structure. With precise angles and high symmetry, these plates can evenly distribute concentrated high-temperature molten metal and optimize fluid flow path. They prevent flow deflection, flow accumulation and turbulent flow during casting, and ensure consistent flow rate for multi-strand casting. Standard space is reserved inside the trough for laying refractory materials. Refractory bricks or castable refractories can be installed subsequently to achieve excellent high-temperature resistance, scour resistance and corrosion resistance, fully meeting the high-temperature working requirements of metallurgical operations.
II. Core Manufacturing Processes
The diversion chute is a non-standard custom steel structural product without fixed standard specifications. It is tailor-made according to the customer’s production line layout, casting flow rate and number of casting strands. High requirements are imposed on machining accuracy and welding technology. All manufacturing procedures comply strictly with heavy industry steel structure production standards to guarantee regular structure and stable performance of finished products.
Strict dimensional control is implemented during plate cutting to ensure tight fitting and high joint accuracy of components. Bending and forming are performed in standardized procedures to guarantee flatness and regular shape of the trough body. In the assembly stage, the installation angle, symmetry and overall geometric dimension of flow guide plates are calibrated emphatically to guarantee diversion performance from the source. Full penetration welding is adopted for fabrication, delivering dense and uniform welds free of pores, slag inclusions and other process defects. It greatly improves the structural strength of the equipment and avoids cracking and deformation caused by long-term high-temperature thermal stress. Finished products undergo comprehensive dimensional inspection and weld dressing before delivery to ensure compliance with quality standards.
III. Practical Application Performance
The structural accuracy and fabrication quality of diversion chutes directly affect the stability of continuous casting and the quality of finished castings. Well-made diversion chutes can distribute high-temperature molten metal in a steady and regular manner, stabilize casting flow velocity and direction, greatly reduce casting defects and improve overall production efficiency.
Compared with ordinary steel structural parts, metallurgy-specific diversion chutes feature higher structural strength, better high-temperature resistance and superior scour resistance, adapting to high-intensity and heavy-load working conditions in the metallurgy industry. The equipment has a solid structure, low failure rate and wide adaptability, and can meet customized demands of steelmaking and foundry production lines of various specifications. As an indispensable supporting equipment in continuous casting processes, diversion chutes rely on solid structural quality to provide reliable support for safe, stable and efficient metallurgical production.
