Water penetration device capable of controlling temperature of steel head

Abstract

The invention discloses a steel head temperature-controllable water penetration device. A steel head penetrating through the water penetration device is not subjected to water treatment or is subjected to less water treatment, so that enough steel head temperature is ensured. Comprising a water tank, a mounting support and a cooler are arranged above the water tank, the cooler is fixed to a supporting beam, the two ends of the supporting beam are fixedly supported on the mounting support, the cooler comprises a water penetrating guide pipe with a through steel running hole, a water filling cavity is formed in the front end of the water penetrating guide pipe, and a first cooling groove is formed in the position, at the rear end of the water filling cavity, in the steel running hole; a second cooling tank provided with a water blocking nozzle is arranged at the rear end of the water penetrating guide pipe, a water inlet guide pipe is arranged at the front end of the water penetrating guide pipe, a first electric control valve is arranged on the water inlet guide pipe, and a water outlet guide pipe is arranged at the rear end of the water penetrating guide pipe; and a hot metal detection device with the detection direction pointing to the axis of the steel running hole is arranged at the front end of the water tank in front of the cooler.

Description

technical field [0001] The invention relates to a water penetration device, in particular to a water penetration device with a controllable steel head temperature. Background technique [0002] The second bar line of our steel rolling division is a full continuous rolling bar hot rolling production line with an annual designed capacity of 800,000 tons. The main products are construction bars (steel) with a diameter of 18-25MM. Since it was completed and put into use in 2006, the production capacity has increased year by year. By 2019, the production capacity of the rolling line will reach 1 million tons, and the load will exceed the design capacity by 25%. The equipment in the middle and finishing rolling areas of the main rolling line frequently causes equipment accidents due to overload. In March 2020, in order to reduce the accident rate, the equipment was upgraded to reduce the failure rate. [0003] Since it was upgraded and put into use in May 2020, the steel head fro...

Problems solved by technology

[0003] Since it was upgraded and put into use in May 2020, the steel head at the exit of No. 16 rolling mill has passed through the 38-meter-long water-running trough to the steel head at the entrance of No. 17 rolling mill. After process verification, the reason for the steel punching is: steel head steel The temperature is too low, resulting in relatively high hardness of the steel head. When entering the rolls of the No. 17 rolling mill, the steel head slips and cannot enter the rolls of the stand smoothly, resulting in steel punching.
