Document Type and Number:
WIPO Patent Application WO/2018/176790
Kind Code:
A1
Abstract:
A high carbon equivalent and high low-temperature toughness pipeline steel plate for an X80 elbow pipe and a manufacturing method therefor. The method has the characteristics of simple process and high yield. The thickness of the steel plate is 18.4-42 mm. The manufacturing process is as follows: preparing materials according to proportions; smelting same by a converter or an electric furnace; refining same outside the converter or furnace; performing continuous casting; reheating a plate blank; performing rolling, and ACC gradient cooling; and straightening. The steel plate has excellent low-temperature toughness; the manufacturing method therefor is simple and easy, and brings high yield.
