[0004] In addition, in the prior art, the cooling water in the cooler remains at the bottom of the cooler under the action of gravity. After the rolled piece enters the cooler, the surface of the rolled piece facing the bottom of the cooler is subjected to excessive cooling, which leads to uneven cooling of the rolled piece. Affect the metallographic structure of the rolled piece itself

The invention provides a steel rolling water-cooling control box. The box comprises a box body, wherein a water-cooling line is arranged between an inlet and an outlet of the box body, the water-cooling line comprises a cooler used for cooling a rolled piece and a reverse dehydrator used for purging water attached to the rolled piece which are sequentially arranged, a first air passing pipe used for draining water is arranged between the cooler and the inlet of the box body, a second air passing pipe used for draining water is arranged between the cooler and the reverse dehydrator, and a thirdair passing pipe used for draining water is arranged between the reverse dehydrator and the outlet of the box body. Cooling water of the rolled piece can be completely sealed in the water-cooling box, and the rolled piece is prevented from bringing out residual water to subsequent procedure equipment.
Description
technical field [0001] The invention relates to the technical field of steel rolling water cooling, in particular to a steel rolling water cooling control box. Background technique [0002] After the hot-rolled steel is rolled out of the rolling mill, it needs to be cooled by a water-cooled control box to reach the required temperature and obtain the corresponding metallographic structure. Usually, multiple coolers connected in series are installed in the water-cooled control box to cool the rolled piece. [0003] In the prior art, when the rolled piece is cooled and output from the end of the water-cooled box, a large amount of water is carried out from the rolled piece, and a large amount of residual water is brought into the post-processing equipment along with the rolled piece, which brings inconvenience to the operation of the subsequent equipment. In the actual rolling process, the rolled piece is not allowed to bring residual water from the water cooling box. [000...
