product details

Production technology

Hot-rolled H-beams are manufactured through a continuous hot-rolling process. The steel billet is heated above the recrystallization temperature and successively passes through multiple sets of rolling mills, gradually deforming into the final "H"-shaped cross-section. This process achieves synchronous formation of the web and flanges, ensuring dimensional accuracy and uniform mechanical properties of the product.

Detailed explanations for each step

Frontend: Steelmaking & Casting

1. Hot metal pretreatment – Remove sulfur, phosphorus, and other impurities.

2. Converter/EAF steelmaking – Smelt molten iron/scrap into steel and adjust chemical composition.

3. Secondary refining (LF/VD) – Further deoxidize, desulfurize, precisely control alloys (V, Nb, Cr, etc.), and remove inclusions to improve purity.

4. Shaped casting – Cast steel into a beam blank approximating the final H-shape to improve rolling efficiency.

Backend: Rolling & Finishing

5. Billet heating – Heat the beam blank in a walking-beam furnace to 1180–1300°C for uniform austenitization.

6. Breakdown rolling (BD mill) – Roll the heated billet through multiple passes to form a "dog-bone" intermediate blank (total reduction ≥50%).

7. Universal finishing (CCS mill) – Core forming step using horizontal rolls to control web thickness and vertical rolls to control flange dimensions with high precision.

8. Sawing and cooling – Cut head and tail with a hot saw, then cool naturally on a cooling bed (upright position to prevent deformation).

Q: What is hot-rolled H-beam?

A: Hot-rolled H-beam is an H-shaped cross-section steel formed in a single pass through a universal mill at high temperatures, featuring parallel inner and outer flanges and right-angled ends.

Q: What is the difference between hot-rolled and welded H-beams?

A: Hot-rolled beams are formed in one pass with low residual stress, stable performance, and lower cost; welded beams are made by welding steel plates, offering flexible specifications and customizable non-standard sizes.
