Abstract
The invention relates to a method for providing a starting signal for a mill loop. The method comprises the following steps of: inputting a triggering signal for starting the loop in a control part, wherein the detected rising edge of a rolled piece at the outlet of an upstream rack of the loop serves as the triggering signal; computing the time for the rolled piece to reach the inlet part of a downstream rack by the control part after the control part receives the triggering signal; and then sending the starting signal for driving the loop to act to a drive device from the control part. According to the method, a measuring instrument is only used for detecting the rising edge of the rolled piece in the upstream rack, which serves as the triggering signal, and the starting signal is generated by computing the outlet speed of the rolled piece at the upstream rack and the distance between the upstream and downstream racks in real time, so that steel is prevented from piling when the starting signal is adopted to drive the loop to act.
Description
Technical field
the present invention relates to a kind of method that enabling signal is provided for the milling train kink.
Background technology
existing rod-rolling mill; Quite fast because of the speed of its rolled wire, in order to guarantee the dimensional accuracy of rolled piece,, high-precision main transmission automatic control system realizes the dynamic adjustments of roll rotational speed except that must being set; Also need on rolling line, to be provided with several kinks; So that the wire rod that is rolled can be rolling in tension-free condition, this shows that kink is to guarantee rolling automated production and the indispensable visual plant of quality.In the process of high-speed rolling wire rod, kink adjustment tension force is to realize through the height that changes kink, and the adjustment of looper height is to send the enabling signal that drives the kink action to drive unit after receiving enabling signal through control assembly, so that the kink action.
existing milling train all adopts the rolling mode rolled wire of two-wire; And, cause adjacent two milling trains longer at interval between middle milling train group and the pre-finishing mill group, respectively be provided with the flying shearing machine that the wire rod that is rolled is cut off between pre-finishing mill group and the mm finishing mill unit.Because the purpose of kink is set on the milling train is in order to alleviate the tension force of rolled piece, so only kink lifts and could solve strain problem the wire rod that is rolled belongs to frame entering downstream, the upper reaches frame at position from this kink after.For this reason; Kink between the unit rises and falls and stings the completion of steel signal according to the upstream and downstream frame; And measuring instrument is divided into the roll shop building that both direction directly detects upper reaches frame and downstream frame whether rolled piece is arranged, if the roll shop building of upper reaches frame and downstream frame all has rolled piece, just stings the steel signal to produce; And will sting the steel signal and be input in the control assembly, control assembly receive the upstream and downstream frame sting behind the steel signal at once to drive unit send drive the kink action enabling signal to drive the kink action.Yet, because after rolled piece cut off by flying shearing machine, also will be through could from roll, exporting after a while; And during this period of time, the upstream and downstream frame is produced stings the steel signal and also can exist, and does not also walk out the downstream frame such as a last rolled piece and can exist and sting the steel signal; And next rolled piece has got into upper reaches frame and also can exist and sting the steel signal, in this case, can be satisfied with the condition of kink action fully; Cause kink to produce action for the second time, when kink is lifted, be easy to next rolled piece passed from the kink bottom by the termination of next rolled piece bump; And then can cause rolled piece heap steel, production heat is stopped.
Summary of the invention
task of the present invention provide a kind of utilize that the mode of calculating enabling signal interval time solves heap steel problem the method for enabling signal is provided for the milling train kink.
What
were proposed by the invention may further comprise the steps for the milling train kink provides the method for enabling signal: at first with the rising edge of detected kink upper reaches frame outlet rolled piece as the trigger pip that starts kink and be entered in the control assembly; Control assembly calculates the time that this rolled piece arrives frame inlet portion position, downstream after receiving trigger pip, control assembly sends the enabling signal that drives the kink action to drive unit more then.
said control assembly receives that trigger pip adopts distance between upper reaches frame and the downstream frame divided by the income value of the rolled piece velocity of discharge of upper reaches frame to sending enabling signal institute interlude.
What
were proposed by the invention provides in the method for enabling signal for the milling train kink; Measuring instrument detects the rising edge of rolled piece in the frame of the upper reaches as trigger pip, and enabling signal is to be calculated in real time by the velocity of discharge of upper reaches frame rolled piece and the distance between the upstream and downstream frame, so; Adopt this kind enabling signal to drive the kink action and steel can not occur piling; Just not can not produce heat and stop and do not pile steel, can improve wire rod rolling rhythm, improve output and reduce the rolled wire cost.
Embodiment:
fall behind under kink, earlier kink are blocked.When measuring instrument detects the rising edge of upper reaches frame outlet rolled piece at position, kink place; This signal that measures is input in the control assembly as trigger pip, and control assembly just sends the enabling signal that drives the kink action to drive unit after after receiving trigger pip, postponing a period of time.The time that control assembly postpones after receiving trigger pip calculates in the following manner: at first kink is belonged to the upper reaches frame at position and the distance between the frame of downstream is input in the control assembly; When mill milling wire rod rolled piece; Measuring instrument detects the rolled piece velocity of discharge and is input in the control assembly again; When control assembly calculates distance between upper reaches frame and the downstream frame divided by rolled piece velocity of discharge institute value; Be control assembly and receiving trigger pip institute interlude, send the enabling signal that drives the kink action to drive unit again after the time that control assembly is calculated at interval, so that the kink action.
Claims (2)
1. the method for enabling signal is provided for the milling train kink; It is characterized in that may further comprise the steps: at first with the rising edge of detected kink upper reaches frame outlet rolled piece as the trigger pip that starts kink and be entered in the control assembly; Control assembly calculates the time that this rolled piece arrives frame inlet portion position, downstream after receiving trigger pip, control assembly sends the enabling signal that drives the kink action to drive unit more then.
2. method according to claim 1 is characterized in that: said control assembly receives that trigger pip adopts distance between upper reaches frame and the downstream frame divided by the income value of the rolled piece velocity of discharge of upper reaches frame to sending enabling signal institute interlude.
