As shown in fig. 1, the rod hot rolling production system capable of avoiding the steel punching accident of the number 17 rolling mill according to the present invention is shown, and is analyzed by investigation: the water penetration grooves with the length of 38 meters are arranged between the outlet of the No. 16 rolling mill and the inlet of the No. 17 rolling mill (the water penetration grooves are added for the rolled steel which needs to be cooled in order to ensure the metallic phase requirement), the water penetration pressure requirement of the cooling water at the normal temperature state reaches 2.5-2.7MP, and the rolled finished product can not ensure the metallic phase quality when the pressure requirement is lower than the pressure requirement. As the steel head firstly comes out from the outlet of the No. 16 machine and is washed by water pressure through the water running groove with the length of 38 meters, when the steel head reaches the inlet of the No. 17 machine, the temperature is too low, the hardness is too high to smoothly enter the inlet of the No. 17 machine, and the steel impact accident is caused when steel is piled at the inlet.
Through field investigation:
the acquisition personnel measure the steel temperature of the steel head entering the inlet of the stand at the inlet of the No. 17 machine for 100 times, find that 17 times can not enter the inlet of the stand, and measure the temperature of the steel head to be lower than 870 ℃, namely 870 ℃ is the temperature low point of the low-temperature steel head where steel punching occurs, and is the highest temperature to be ensured for ensuring that the steel is qualified in rolling (namely the steel temperature can not exceed 870 ℃). Therefore, the scheme needs to control the temperature of the steel head to be more than 870 ℃ so as to ensure that the steel head can enter the inlet of the No. 17 rolling mill.

The current field setting is that the total length of a water-through running groove of a water-through device is 36 meters, the water-through running groove comprises a plurality of water-through coolers 1, the water-through coolers 1 are correspondingly divided into 3 groups by using switch valves 4, the water supply pressure is controlled by a cooling main station, the pressure is 25-27KP, and the temperature of steel output by a No. 16 rolling mill is rapidly reduced from 930 ℃ to 870 ℃ below the water-through distance of 38 meters before the steel enters a No. 17 rolling mill, so that the temperature meeting the steel rolling requirement reaches the inlet of the No. 17 rolling mill. The cage cover of wearing the water tank can play the effect of certain isolation operational environment and vapor, can slow down the quick diffusion of vapor, improves the working space environment, plays the safety isolation guard action simultaneously.
And a steel head identification device 5 is arranged between the water passing tank and the No. 16 rolling mill, and the position of the steel head in the water passing device is calculated and judged according to the steel head identification time and the steel head moving speed. Further, steel head detection device is provided with the support cover including being used for the fixed mount pad of installation on the mount pad, support the cover rear side be provided with mount pad fixed connection's the mouth of blowing, it is provided with hot metal detector to blow on one side of the back side of chewing, pass support cover and blow off through the mouth of blowing blowout high-pressure draught from 16 steel of rolling mill output after the surperficial dregs through hot metal detector and get into and wear the water installation, hot metal detector is used for detecting and discerning the steel head. In order to facilitate the passing of the steel head, the end of the support sleeve close to the No. 16 rolling mill is provided with a horn-shaped guide part.
Furthermore, a breaking and shearing device is installed at the rear part of the No. 3 shear, and when a steel punching accident occurs, the breaking and shearing device executes a breaking and shearing instruction.
Further, the water passing device stops water cooling treatment on the steel output from the No. 16 rolling mill when the breaking and shearing instruction works.
The No. 3 shears are used for shearing a steel head which comes out from an outlet of a No. 16 rolling mill and passes through 3 groups of water-through coolers, so that the steel head is free from defects such as blooming head and the like, the temperature is not lower than 870 ℃ so as to smoothly enter an inlet of a No. 17 machine frame, and the breaking shears are used for starting a breaking and steel shearing function when a steel punching accident occurs and the like. Through field verification, the temperature of the steel head is stabilized above 900 ℃ before entering a No. 17 rolling mill.
The control method is characterized in that a switch valve is controlled by a PLC (programmable logic controller) unit, the PLC unit is connected with a breaking and shearing device at the rear part of a No. 3 shear so as to send a breaking and shearing signal to the breaking and shearing device to execute a breaking and shearing instruction, a monitoring device close to a No. 16 rolling mill is connected with the PLC unit so as to feed back a detection result to the PLC unit, an operating unit capable of manually executing and controlling the PLC unit is led to be operated, the whole-line control operation is facilitated, and meanwhile, a safety monitoring worker can quickly execute the breaking and shearing signal through the operating unit when recognizing a steel punching accident.
And calculating and programming a PLC control system to execute a valve opening and closing action command when the steel head passes through by matching the speed of the production line through the detection device. It is worth noting that the switch valves are grouped, rather than being individually controlled one by one, compared with the switch valves being individually controlled one by one, the grouping has the advantages of saving the output interface of the PLC, reducing the memory of the PLC program, and improving the stability of the system while ensuring the use effect.
