Detailed description of the invention
Technical scheme in the present invention is understood better in order to make those skilled in the art person, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, should belong to the scope of protection of the invention.
The milling method of wire rod comprises following step: the high temperature billet steel through heating furnace heating is rolled into wire rod in the equipment such as roughing mill 1, finishing mill 2, the wire rod of roll forming is exported by Laying head 6 and spues, and transferred to collection reel 8 entrance by air-cooled roller-way 7, be collected on the plug 11 below collection reel 8 eventually through collection reel 8, wherein, air-cooled roller-way 7 is made up of multistage roller-way, be arranged between Laying head outlet and collection reel entrance, each section of roller-way is driven by an independent driving arrangement, and driving arrangement can control the running speed of roller-way belonging to it.
A kind of high-speed wire rolling control method that the embodiment of the present invention provides collect reel 8 break down normally can not collect the coil of wire 12 time, (position in production line between heating furnace to Laying head 6) in rolling line is made just temporarily to be collected on air-cooled roller-way 7 at rolled steel by the operation reserve changing air-cooled roller-way 7, recover normally until collection reel 8, again the coil of wire 12 on air-cooled roller-way 7 is collected into collection reel 8, just carry out enforceable broken section of operation at rolled steel in rolling line when avoiding collection reel 8 to break down, thus improve the recovery rate of metal.
A kind of high-speed wire rolling control method schematic flow sheet that Fig. 2 provides for the embodiment of the present invention, it comprises the steps:
Step S100: the duty of detected set reel, sends collection reel fault-signal or collection reel normal signal according to the duty of collection reel;
Collection reel 8 is end-equipments in high-speed wire production line, for collecting the coil of wire 12 on air-cooled roller-way 7, but causes collection reel 8 may occur various fault because the plant equipment complex structure, the action that collect reel 8 place are loaded down with trivial details and can not normally collect the coil of wire 12.In order to avoid causing the coil of wire 12 to cause upstream equipment to damage at mounded upstream due to collection reel 8 fault, the duty of the real-time detected set reel 8 of the embodiment of the present invention, the duty of detected set reel 8 comprises manual detection and/or electronic equipment detects automatically.
Wherein, manual detection comprises: operating personnel are by relevant device or the duty only according to subjective judgement detected set reel 8, if detected set reel 8 breaks down, then send collection reel 8 fault-signal by wired or wireless channel to controller, respective action is carried out by the relevant device in controller production control line, the control of usual high-speed wire production line uses PLC (programmable logic controller (PLC)) or DCS controller (dcs controller), and the present invention does not limit this.
Electronic equipment automatically detects and comprises: arrange related sensor at the correspondence position of collection reel 8, as infrared sensor, ultrasonic sensor etc., detected by the duty of sensor to collection reel 8 and generate corresponding collection reel fault-signal or collection reel normal signal, collection reel fault-signal or collection reel normal signal are sent to controller by wired or wireless channel, carry out respective action by the relevant device in controller production control line.The reason that collection reel 8 normally can not collect the coil of wire 12 comprises equipment fault, coil of wire extension frame, changes plug etc.
Step S200: judge whether to receive collection reel fault-signal, if so, then send variable-speed operation signal to air-cooled roller-way, and send time-out tapping signal to heating furnace;
Because air-cooled roller-way 7 is made up of multistage roller-way, and every section of roller-way is driven by an independent driving arrangement, and therefore can be run by driving arrangement drive every section of roller-way, namely the speed of service of every section of roller-way can independently control.
Under normal circumstances, on air-cooled roller-way 7, Homogeneous cooling is obtained in order to make the coil of wire 12, controller controls every section of roller-way and runs with identical speed, namely air-cooled roller-way 7 travels at the uniform speed, then the arrangement mode of the coil of wire 12 on air-cooled roller-way 7 as shown in Figure 3, between the adjacent coil of wire 12, interval is identical, and air-cooled roller-way 7 at the uniform velocity transmits.
If controller receives collection reel fault-signal, illustrate that collection reel 8 can not normally collect the coil of wire 12, now, if air-cooled roller-way 7 continues to run, the coil of wire 12 on air-cooled roller-way 7 likely falls at the end of air-cooled roller-way 7 or on air-cooled roller-way 7, piles up the damage causing Laying head 6.
In embodiments of the present invention, when controller receives collection reel fault-signal, variable-speed operation signal is sent to air-cooled roller-way 7, after air-cooled roller-way 7 receives variable-speed operation signal, according to the variable-speed operation strategy variable-speed operation preset, described variable-speed operation strategy comprises: the speed along Laying head 6 to each section of roller-way in collection reel 8 direction reduces successively, and the nearest one section of roller table speed of distance set reel 8 is 0, the nearest one section of roller table speed of distance Laying head 6 is less than the speed of its variable-speed operation previous moment.
That is, after air-cooled roller-way 7 receives variable-speed operation signal, according to certain rule, the speed of every section of roller-way in air-cooled roller-way 7 is readjusted, improve the capacity of the coil of wire 12 on air-cooled roller-way 7, be just temporarily stored in rolling line on air-cooled roller-way 7 at rolled steel.In order to avoid the end of the coil of wire 12 at air-cooled roller-way 7 falls, the nearest one section of roller-way of command range collection reel 8 is out of service, namely the speed of one end roller-way that distance set reel 8 is nearest is 0, speed along the every section of roller-way in collection reel 8 to Laying head 6 direction increases progressively successively, adopt the speeds control of gradual change, can not fall at the end of air-cooled roller-way 7 while making the coil of wire 12 continue to run on air-cooled roller-way 7.
Because the capacity of the coil of wire 12 on air-cooled roller-way 7 is relevant with the speed of service (average speed of all roller-ways) of air-cooled roller-way 7, be specially, the speed of service of air-cooled roller-way 7 and the capacity of the coil of wire 12 are inversely proportional to, the speed of service is less, the capacity of the coil of wire 12 is larger, therefore, in order to improve the capacity of the coil of wire 12 on air-cooled roller-way 7, one end roller table speed nearest apart from Laying head 6 is preferably less than the speed of its variable-speed operation previous moment, is namely less than speed when air-cooled roller-way 7 travels at the uniform speed.But, in the process of air-cooled roller-way 7 variable-speed operation, its speed of service is also not the smaller the better, such as, if the speed of service of air-cooled roller-way 7 is too small, the coil of wire 12 then on air-cooled roller-way 7 likely overlaps, the coil of wire 12 is caused to pile up on air-cooled roller-way 7 and can not normally run, in a preferred embodiment, the one section roller table speed nearest apart from Laying head 6 is that it runs the 70%-80% of previous moment speed, and speed difference between adjacent two sections of roller-ways is identical, to maximally utilise the space on air-cooled roller-way 7.
In addition, space on air-cooled roller-way 7 is limited, then it is to the finite capacity of the coil of wire 12, although the variable-speed operation of air-cooled roller-way 7 can temporary cache continue produce the coil of wire 12, if but the coil of wire 12 continuous production always exceedes the limit that air-cooled roller-way 7 can hold, and causes the coil of wire 12 to be piled up on air-cooled roller-way 7.Therefore, in embodiments of the present invention, while air-cooled roller-way 7 variable-speed operation, controller controls heating furnace and suspends tapping, and that is, air-cooled roller-way 7 just continues to collect in rolling line just at rolled steel, when in rolling line just after rolled steel has been collected, there will be no new steel billet to enter production line, ensure the reliability of system, avoid the generation of above-mentioned phenomenon.
Understand the operation reserve of air-cooled roller-way in the embodiment of the present invention for the ease of those skilled in the art better, be illustrated below in conjunction with a specific embodiment.
Fig. 4 is the embodiment of the present invention air-cooled roller-way 7 structural representation, as shown in Figure 4, air-cooled roller-way 7 is made up of nine sections of roller-ways, the first roller-way D1, the second roller-way D2, the 3rd roller-way D3, the 4th roller-way D4, the 5th roller-way D5, the 6th roller-way D6, the 7th roller-way D7, the 8th roller-way D8, the 9th roller-way D9 is respectively to collection reel 8 by Laying head 6, (collection reel 8 can normally collect the coil of wire 12) nine sections of roller-ways run with identical speed V0 under normal circumstances, and namely air-cooled roller-way 7 travels at the uniform speed.
When collection reel 8 breaks down time-out collection, controller sends variable-speed operation signal to air-cooled roller-way 7, change the operation reserve of air-cooled roller-way 7, first roller-way D1 is adjusted to successively to the speed of the 9th roller-way D9: V1=0.8V0, V2=0.7V0, V3=0.6V0, V4=0.5V0, V5=0.4V0, V6=0.3V0, V7=0.2V0, V8=0.1V0, V9=0.0, forbid that heating furnace is tapped simultaneously, the now arrangement of the coil of wire 12 on air-cooled roller-way 7 as shown in Figure 5, gap between the coil of wire 12 is reduced to collection reel 8 successively by Laying head 6, the increasing number of the coil of wire 12 on air-cooled roller-way 7, make full use of the space of air-cooled roller-way 7.
Step S300: judge whether to receive collection reel normal signal, if so, then send to air-cooled roller-way the signal that travels at the uniform speed, and send continuation tapping signal to heating furnace;
The duty of real-time detected set reel 8, when detecting that collection reel 8 recovers normally, controller sends to air-cooled roller-way 7 signal that travels at the uniform speed, after air-cooled roller-way 7 receives the signal that travels at the uniform speed, the speed of the first roller-way D1 to the 9th roller-way D9 is all adjusted to V0, namely air-cooled roller-way 7 travels at the uniform speed with speed V0 again, and the coil of wire 12 temporary on air-cooled roller-way 7 is sent to collection reel 8 and collects, the arrangement of the coil of wire 12 on air-cooled roller-way 7 returns to the state shown in Fig. 3 gradually.In addition, because the collection reel 8 of production line end recovers normal collection work, if now upstream rolling line continuation steel rolling can not produce packing phenomenon again, therefore, send to heating furnace while sending to air-cooled roller-way 7 signal that travels at the uniform speed and continue tapping signal, make heating furnace again input new steel billet to rolling line, production line returns to normal condition.
On the basis of above-mentioned high-speed wire rolling control method, the present invention also provides another kind of high-speed wire rolling control method, the another kind of high-speed wire rolling control method flow chart that Fig. 6 provides for the embodiment of the present invention, as shown in Figure 6, further comprising the steps of after said method step S200:
Step S201: judge whether to receive rolling line and to weave silk settling signal without steel signal and Laying head, if so, then send signal out of service to armamentarium in production line;
Whether also there are steel in real-time detection rolling line and Laying head 6 exports whether also there is steel wire, there are not steel if detected in rolling line, then send rolling line without steel signal to controller; If detect that Laying head 6 exports and there is not steel wire, then send Laying head to controller and to weave silk settling signal.If controller receives rolling line and to weave silk settling signal without steel signal and Laying head simultaneously, illustrate that the upstream of air-cooled roller-way 7 can not produce the new coil of wire 12 again, the armamentarium now controlled in air-cooled roller-way 7 is out of service.
According to the variable-speed operation strategy of air-cooled roller-way 7, when air-cooled roller-way 7 variable-speed operation, the speed except the 9th roller-way D9 is except 0, and other roller-way all runs with certain speed, the coil of wire 12 is transferred to next stage roller-way.If air-cooled roller-way 7 continues variable-speed operation state, the coil of wire 12 then on air-cooled roller-way 7 can all transfer on the 9th roller-way D9 eventually, form the accumulation of the coil of wire 12, therefore, the embodiment of the present invention is while guaranteeing that upstream can not produce the new coil of wire 12, stop the operation of air-cooled roller-way 7, avoid the accumulation of the coil of wire 12 further.
Be below the entire protocol of the another kind of high-speed wire rolling control method of the present invention:
Step S100: the duty of detected set reel, sends collection reel fault-signal or collection reel normal signal according to the duty of collection reel;
Step S200: judge whether to receive collection reel fault-signal, if so, then send variable-speed operation signal to air-cooled roller-way, and send time-out tapping signal to heating furnace;
Step S201: judge whether to receive rolling line and to weave silk settling signal without steel signal and Laying head, if so, then send signal out of service to armamentarium in production line;
Step S300: judge whether to receive collection reel normal signal, if so, then send to air-cooled roller-way the signal that travels at the uniform speed, and send continuation tapping signal to heating furnace.
As can be seen from the above step, receive collection reel 8 normal signal in the present embodiment step S300 before, air-cooled roller-way 7 is likely in two states: one is variable-speed operation state, such as, after collection reel 8 breaks down, the fault that operating personnel eliminate rapidly collection reel 8 makes collection reel 8 can continue to collect the coil of wire 12, and the steel now in the rolling line of upstream also do not have rolling to complete; Another kind is halted state, and such as, operating personnel take the fault that the long period gets rid of collection reel 8, and now, do not have steel in the rolling line of upstream, Laying head 6 has also been weaved silk, then air-cooled roller-way 7 is controlled out of service by controller.
But, no matter which kind of state air-cooled roller-way is in, after receiving collection reel normal signal, all can control air-cooled roller-way and travel at the uniform speed and control heating furnace continuation tapping, its difference is only that air-cooled roller-way is adjusted to travel at the uniform speed or be adjusted to by halted state by variable-speed operation to travel at the uniform speed.That is, the high-speed wire rolling control method that the embodiment of the present invention provides goes for various different state in production line.
