Abstract
Provided is a water-through cooling automatic control device. A pneumatic valve is additionally mounted in front of a hand valve of a water-through cooling device, and a control system of the pneumatic valve is in electric connection with a programmable logic controller (PLC) control cabinet on a main motor. The pneumatic valve controls open or close of a valve with current of a main motor of a rolling line tail frame rolling mill as a signal, when steel enters a rolling mill, the control system of the pneumatic valve obtains the signal from the PLC control cabinet on the main motor, the pneumatic valve is started to send water, the starting time of the pneumatic valve is delayed through a PLC of the main motor according to rolling speed and the distance between the rolling mill and the water-through cooling device, with timely adjustment, head portion avoiding length is adjustable in a reasonable range, and tail portion avoiding length is also adjustable. According to the water-through cooling automatic control device, signals of the PLC of a finishing mill is obtained, automatic water feeding and water stoppage of the water-through cooling device are achieved, and the effect that water is fed when steel exists and water is stopped when the steel does not exist is achieved. The phenomena of black head and head bending of the head portion of steel due to uneven cooling are avoided, and the water-through cooling automatic control device can be widely used in rod and wire tandem rolling production lines of various steel and iron enterprises.
Description
Technical field:
The utility model relates to a kind of wire and rod continuous rolling production line and wears the automaton of water-cooled.
Background technology:
Wearing water cooling plant is to establish an adjustable water-cooled section that is comprised of several water cooling boxes behind finishing mill, bar is sharply cooled off, make Surface of Rod Bar form martensitic structure, in temperature recovery process subsequently, the core heat effects on surface martensitic structure that sheds can produce drawing effect, and superficial layer is tempered martensite, and core is particulate pearlite and sorbite tissue, this institutional framework improves bar yield limit and toughness, and has good solderability.At present iron and steel enterprise widely used wear water cooling plant since can not realize automatically to, cut off the water, often cause small dimension steel head to produce blackhead and elbow phenomenon because of inhomogeneous cooling, thereby cause steel scrap.Addressing this problem becomes urgent need.
The utility model content:
Overcome the deficiencies in the prior art, design and a kind ofly realize that excellent wire rod wears water cooling plant hide head and the automaton of tail of hiding.A kind of water-cooled automaton of wearing is to install operated pneumatic valve additional before wearing the water cooling plant manually-operated gate, and the control system of operated pneumatic valve is electrically connected with PLC switch board on the main motor.The course of work of this device is: operated pneumatic valve comes opening or closing of by-pass valve control take roll line end rolling mill Main motor current as signal, when steel are nipped milling train, the control system of operated pneumatic valve PLC switch board from the main motor obtains signal, start operated pneumatic valve and send water, operated pneumatic valve start-up time is according to mill speed, milling train and wear the water-cooled distance by the given time-delay of main motor PLC, adjust in good time, guarantee to hide a length at zone of reasonableness and adjustable, the tail of hiding also is as a same reason.The utility model is realized wearing the self water feeding of water-cooled and cutting off the water by taking from finishing mill PLC signal, realizes having the steel feedwater, cuts off the water without steel.Therefore can avoid the steel head to produce blackhead and elbow phenomenon because of inhomogeneous cooling.
Description of drawings:
Fig. 1 is the utility model front view.
The specific embodiment:
A most preferred embodiment of the present utility model, such as figure, install in front of the door operated pneumatic valve 2 additional wearing water cooling plant hand-operated valve 1, it is that signal comes opening or closing of by-pass valve control that operated pneumatic valve adopts roll line end rolling mill Main motor current, when steel are nipped milling train, the control system of operated pneumatic valve PLC switch board from the main motor obtains signal, start operated pneumatic valve and send water, operated pneumatic valve start-up time is according to mill speed, milling train and wear the water-cooled distance by the given time-delay of main motor PLC, adjust in good time, guarantee to hide a length at zone of reasonableness and adjustable.The tail of hiding also is as a same reason.
Claims (1)
1. wear the water-cooled automaton for one kind, it is characterized in that: install operated pneumatic valve additional before wearing the water cooling plant manually-operated gate, the control system of operated pneumatic valve is electrically connected with PLC switch board on the main motor.
