Hot-rolled rod wire cooling equipment

Abstract

The invention discloses hot-rolled rod wire cooling equipment. The cooling equipment comprises a cooling tank, wherein a spraying device is arranged in the cooling tank and is used for spraying waterand cooling a rod wire in the cooling tank, the spraying device is connected with a water supply device, the top end of the interior of the cooling tank is provided with a condensation collection device, the condensation collection device communicates with the water supply device, and the condensation collection device is used for reflowing the collected condensed water to the water supply devicefor recycling. The cooling equipment is provided with the relatively closed cooling tank as an execution environment of a cooling process, the condensation collection device is arranged at the top ofthe relatively closed box body environment, cooling water evaporated by the cooling process is collected, the cooling water rises to reach the position where the condensation collection device locatedafter being evaporated to form steam, so that the cooling water is subjected re-condensation and reflux and is effectively collected by the device, the collected cooling water returns to the water supply device again and is resupplied to the spraying device of the equipment through the water supply device, and the collected cooling water is supplied to the cooling equipment to meet the requirement of cooling steel, so that a large amount of water resource waste caused by direct evaporation of cooling water to the atmosphere is avoided.

Description

Technical field [0001] The invention relates to the technical field of steel cooling equipment, and more specifically, to a hot-rolled bar and wire cooling equipment. Background technique [0002] Bar is a simple cross-section profile, generally delivered in strips. The cross-section shapes are round, square and hexagonal, as well as rebar for construction (periodical section). The wire rod is the hot-rolled product with the smallest interrupted surface area and the longest length. Products that are long and delivered in a coiled state have cross-sectional shapes such as round, square, hexagonal and special shapes. [0003] In modern bar and wire rolling production, the rolling speed is very high, and the temperature drop is small or even rises during the rolling process. Therefore, the billet heating temperature is low during the production of bar and wire. When heating, it is necessary to strictly prevent overheating and burning, and minimize the scale. For steel grades that are...
