Description
Technical field
The utility model relates to a kind of roller velocity modulation engagement positions of withdrawal straightening machine, and when being mainly used in the operation of metallurgical steel-making continuous casting withdrawal straightening machine, the speed adjustment coupling of top roll, lower roll and separate roller, belongs to steel-making continuous casting equipment technical field.
Background technology
Along with the develop rapidly of metallurgy industry, current all kinds of steel-making enterprise conticaster quantity sharply increases, and wherein billet caster accounts for significant proportion.But economy, cost set out in very most of enterprise, the production structure generally for conticaster requires all wider of choosing, and the continuous small-billet casting of reaching the standard grade, after producing intrinsic end face strand smoothly, carry out product extension.For example: require the casting blank specification producing different end face on same set of continuous casting, have or even circumference all turn round and look at, need conticaster to become a many-side people.
But improved conticaster often can run into a problem; strand jitter phenomenon; can distinguish from observing time serious; the reason producing strand shake has a lot: radian is forbidden; speed is not mated; all kinds of rod wear condition, there is the many reasons such as gap in roller, reduction box, motor etc., how to adjust roller speed and make the speeds match of each roller be perplex the trouble of plant maintenance technical staff always.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and provide a kind of roller velocity modulation engagement positions of withdrawal straightening machine, it can reduce or stop the generation of jitter phenomenon, realizes qualified products and maximizes.
The purpose of this utility model is achieved in that
The roller velocity modulation engagement positions of the utility model withdrawal straightening machine, comprise upper roll wheel, lower roll wheel and separate roller, described upper roll wheel and lower roll wheel are arranged at the both sides up and down of strand, separate roller is arranged at the rear side of upper roll wheel, described upper roll wheel, lower roll wheel and separate roller are all fitted with strand, the rear side of described separate roller is also provided with multiple driven voller, driven voller is all fitted with strand, described upper roll wheel, lower roll wheel, separate roller respectively by top roll reduction box, lower roll reduction box, separate roller reduction box and upper roller motor, lower roller motor, be separated motor and be connected;
Described upper roll wheel, lower roll wheel, separate roller are respectively equipped with a sensor, three sensors are all connected with the input of PLC, the output of described PLC is connected with three frequency converters respectively, three frequency converters more respectively with upper roller motor, lower roller motor, be separated motor and be connected.
Compared with prior art, the beneficial effect of the roller velocity modulation engagement positions of withdrawal straightening machine is:
It is asynchronous that the roller velocity modulation engagement positions of this withdrawal straightening machine can reduce or stop strand top and bottom, the strand jitter phenomenon caused, thus ensure the surface quality that strand is good, reduces strand loss from spoilage, improve continuous cast products qualification rate.
Accompanying drawing explanation
Fig. 1 is the structural representation of the roller velocity modulation engagement positions of the utility model withdrawal straightening machine.
Fig. 2 is the electrical schematic diagram of the roller velocity modulation engagement positions of the utility model withdrawal straightening machine.
Wherein: upper roll wheel 1, lower roll wheel 2, separate roller 3, driven voller 4, top roll reduction box 5, lower roll reduction box 6, separate roller reduction box 7, upper roller motor 8, lower roller motor 9, separation motor 10, sensor 11, PLC12, frequency converter 13, strand 14.
Detailed description of the invention
See Fig. 1, the utility model relates to a kind of roller velocity modulation engagement positions of withdrawal straightening machine, comprise upper roll wheel 1, lower roll wheel 2 and separate roller 3, described upper roll wheel 1 and lower roll wheel 2 are arranged at the both sides up and down of strand 14, separate roller 3 is arranged at the rear side of upper roll wheel 1, described upper roll wheel 1, lower roll wheel 2 and separate roller 3 are all fitted with strand 14, the rear side of described separate roller 3 is also provided with multiple driven voller 4, driven voller 4 is all fitted with strand 14, described upper roll wheel 1, lower roll wheel 2, separate roller 3 is respectively by top roll reduction box 5, lower roll reduction box 6, separate roller reduction box 7 and upper roller motor 8, lower roller motor 9, be separated motor 10 to be connected.
As Fig. 2, described upper roll wheel 1, lower roll wheel 2, separate roller 3 are respectively equipped with a sensor 11, three sensors 11 are all connected with the input of PLC12, the output of described PLC12 is connected with three frequency converters 13 respectively, three frequency converters 13 more respectively with upper roller motor 8, lower roller motor 9, be separated motor 10 and be connected.
The rotating speed of upper roll wheel 1, lower roll wheel 2, separate roller 3 is obtained by respective sensor 11, after PLC12 obtains the rotating speed of three running rollers subsequently, control signal is passed to frequency converter 13 to control the rotating speed of upper roller motor 8, lower roller motor 9, separation motor 10, thus the rotating speed of three motors is reached unanimity, and then to reduce or to stop strand top and bottom asynchronous, the strand jitter phenomenon caused, thus ensure the surface quality that strand is good, reduce strand loss from spoilage, improve continuous cast products qualification rate.
