Description

Technical Field

[0001] The utility model belongs to the technical field of high-carbon steel wire cooling, and particularly relates to a device for improving the cooling uniformity of high-carbon steel wire rods. Background Art

[0002] When producing high-carbon steel, if the controlled cooling process is improper, abnormal structures will occur in the wire rods. Especially for large-sized wire rods, when the cooling rate is too slow, the sorbite rate is low, and the tensile strength is low, which cannot meet the strength requirements of users for processing prestressed steel strands; when the cooling rate is too fast, abnormal harmful structures such as martensite and bainite will be generated.

[0003] In the actual production process, the wire is in a coiled shape, and the coils are cooled on the air-cooling roller table in a loose coil form. There are two states between the coils: overlapping and non-overlapping. There are gaps in the non-overlapping position of the coils and the cooling is fast, while the coils overlap in the overlapping position and the cooling is slow, resulting in a temperature difference of more than 50°C between the overlapping and non-overlapping positions, and the tensile performance fluctuation at different positions of the same coil exceeding 60 MPa.

[0004] Currently, the wire rods on the air-cooling roller table are usually cooled by the cooperation of a fan, a temperature monitoring device and a Jialing device. However, at present, the temperature measurement on the air-cooling roller table usually only measures the overlapping position, and it is impossible to effectively distinguish the temperature difference at different positions of the wire rod, adjust the Jialing device and the air volume distribution, and accurately control the temperature change specifically.
