The utility model content
The purpose of this utility model provides a kind of can the reparation the band steel that has template shape wave defective, and equipment is simple, invest little, easily operation, the flattening device of the hot rolling thin strip that operating cost is low.
The purpose of this utility model is achieved by taking following technical scheme:
A kind of flattening device of modified hot rolling thin strip, include the centering function uncoiler and uncoiling mechanism, band steel toe portion straightener, side deflector roll, shearing machine, multi-roll straightening machine, wear band roller group, wear band platform and coiling machine, described uncoiler and uncoiling mechanism, band steel toe portion straightener, side deflector roll, shearing machine, multi-roll straightening machine, wear band roller group, wear and be connected and installed the flattening device of forming hot rolling thin strip between band platform and the coiling machine successively.
As of the present utility model further perfect, flattening device also includes the waste material guide table, and the waste material guide table is installed in after the shearing machine, before the multi-roll straightening machine.
Constituting each equipment of the present utility model, all is plant equipment general in the metallurgical industry field, and wherein, described band steel toe portion straightener can adopt 3～7 roll strip head straighteners; Described multi-roll straightening machine can adopt 9～21 roller straighteners, preferred 13～19 roller straighteners, and work roll diameter is 100～150 millimeters.
The installation site of relevant devices and effect are respectively in the utility model:
Uncoiler and uncoiling mechanism that the centering function is arranged are used to support, rotate coil of strip to be repaired, import band steel toe portion straightener with the coil of strip uncoiling and with the coil of strip head of opening;
Band steel toe portion straightener is installed in after uncoiler and the uncoiling mechanism, behind reception and the importing coil of strip head, the band steel is tentatively aligned, and will be with steel to import the side deflector roll;
The side deflector roll is next to after the band steel toe portion straightener, the steel band that imports is wherein worn band and whipping operation, and guiding centering is carried out in the steel band both sides, and the conveyer belt steel is to multi-roll straightening machine;
Shearing machine is used for the band steel behind the aligning is carried out crop after being installed on the side deflector roll;
The waste material guide table is installed on after the shearing machine, is used for taking the lead to import the garbage collection bucket with what have no progeny;
Multi-roll straightening machine is installed in after the waste material guide table, and the band steel that imports is wherein aligned the leveling operation;
Wear band roller group and be installed in after the multi-roll straightening machine, be used for continuing to transmit steel band;
Wear the band platform and be installed in and wear after the band roller group, be used for will the band steel passing to the jaw of coiling machine;
Coiling machine is installed in to be worn after the band platform, and the band steel behind the aligning is batched rolling again.
The flattening device of the utility model hot rolling thin strip is such operation: the coil of strip that has defective (shape wave), be contained on the uncoiler, pass through uncoiling mechanism, to be with steel to send into band steel toe portion straightener and carry out steel band head aligning, the side deflector roll carries out centering to the band steel, make the band steel pass shearing machine and waste material guide table then, after to the steel band crop, import multi-roll straightening machine, multi-roll straightening machine is depressed many upper straightening rolls, under the effect of upper straightening roll and following smoothing roll, makes the repeatedly alternating bending distortion and stressed of band steel, thereby alleviate and eliminate flatness defect (unrestrained type), will be with steel to batch rolling again.
Capital equipment of the present utility model all is a plant equipment general in the metallurgical industry field, be easy to assembling, reduce greatly than existing equipment investment, and also can reach repairing effect preferably, can satisfy industrial application requirements the less steel plate of defect level with milling method reparation steel plate.The utility model is owing to adopt band steel center control technology, and is can fine maintenance behind the belt steel flating consistent with horizontal center line, meets the requirements of the turriform figureofmerit after making the steel band rewinding.
