Abstract

The invention belongs to the technical field of metal material manufacturing, and particularly relates to a production method of an X80 pipeline steel strip with the thickness of 10-16 mm. The production method comprises the following steps: (1) smelting, (2) continuous casting, (3) casting blank cold transferring, (4) casting blank reheating, (5) rough rolling, (6) finish rolling, (7) laminar cooling and reeling, and (8) storing and sampling. The production method can save investment and reduce the occupied land area and energy consumption, and moreover has the advantages of thick and thin slab hot continuous rolling technologies.

Description

technical field

[0001] The invention belongs to the technical field of metal material manufacturing, and in particular relates to a production method of a 10-16mm X80 pipeline steel strip. Background technique

[0002] Among the current production technologies of X80 pipeline steel strip, the most mature technology is the development and production of X80 grade pipeline steel strip using 2050-2300 traditional thick slab hot continuous rolling line. Thin slab continuous casting and rolling generally cannot produce X80 pipeline steel strip . In the current mature production technology (1) 200-250 mm thick slabs are used, which must be equipped with electromagnetic stirring, light reduction and other equipment to ensure the internal quality of the slab, otherwise there will be internal looseness, center segregation, etc., and the thickness of the slab The proportion of fine-grained areas on the surface of the direction is small, and the columnar grains are well developed; (2) ...
