A285 Grade C plates rolling process: rolling system: finishing rolling reduction system: the total reduction rate of the last three passes ≥ 40%, the reduction rate of the finished product pass ≥ 10% (steel width ≥ 2200 mm or thickness ≥ 40 mm or later roll production, Allow the reduction rate of finished products to be reduced by 2.0%).
The advantages of Katalor Steel A285 Grade C steel products:1. Steel is pure. A285 Grade C steel has ultra-high power electric furnace training and perfect outside furnace technology. The extraction rate outside the molten steel furnace reaches 92%, and the vacuum degassing extraction reaches 90%.
2. The function is uniform and excellent. A285 Grade C steel plate rolling is carried out on a 4200mm wide and heavy plate rolling mill equipped with hydraulic AGC automatic thickness control and laser thickness measurement system, using super large ingots and thick slabs, controlled rolling, and low-speed and large reduction The rolling process ensures a satisfactory compression ratio, the steel plate is completely deformed and saturated, the vertical and horizontal functions are uniform, and the internal structure is dense.
3. A285 Grade C steel plate has excellent internal quality and strong ability to ensure qualified flaw detection.
The A285 Grade C steel plate is suitable for medium and low tensile strength carbon steel plates for melt welding pressure vessels.
