Abstract

The invention relates to the technical field of controlled rolling, and discloses a round steel controlled rolling and controlled cooling integrated device. The device comprises an outer furnace and an inner furnace, the two sides of the outer furnace are symmetrically provided with through outlets, the outer sides of the outlets are both provided with cold control chambers correspondingly, fixedbases are arranged in the cold control chambers, adjusting bases are hinged to the fixed bases, the upper parts of the adjusting bases are provided with sealing parts, and the lower parts of the adjusting bases are provided with cooling parts; and each sealing part is composed of a fixing block and a partition plate, the partition plates are positioned on the outer sides of the fixing blocks, thepartition plates are attached to the outlets formed in the outer furnace, through holes are formed in the cooling parts, and spray heads are arranged in the through holes. According to the device, theproblems that round steel controlled rolling and controlled cooling are carried out separately, the manufacturing process of the round steel is incomplete, and the product performance is poor are solved, the controlled rolling and controlled cooling are both convenient to implement, the production scheme is optimized, the product quality is greatly guaranteed, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of controlled rolling, in particular to an integrated device for controlled rolling and cooling of round steel. Background technique [0002] 20G is the high-pressure steel pipe for boilers with the steel grade in GB5310. This type of steel pipe is a special steel for blanks such as high-pressure seamless steel pipes. The steel has good strength and plasticity, excellent welding performance and process performance, and is widely used. [0003] The core of the controlled rolling and controlled cooling process technology of round steel is to improve the strength, toughness and welding performance of the steel by controlling the heating temperature, rolling process, cooling conditions and other process parameters during the rolling process. The controlled cooling process is generally carried out according to the process steps, and the segmented implementation of controlled rolling and controlled cooling will le...
