Abstract
The utility model relates to a raw material off-square prevention device of a rolling mill. The raw material off-square prevention device comprises a memorial archway frame, wherein a positioning plate is arranged on a stand column of the memorial archway frame, two groups of transverse beams are arranged on the side of an inlet of the memorial archway frame, a stopping plate is connected between the two groups of transverse beams, and three groups of horn mouths are sequentially connected on each transverse beams. The raw material off-square prevention device is simple in structure, convenient to install and low in cost, a guiding function and a clamping function for enabling a billet to enter a roller are added on the basis of an original memorial archway frame structure, the use effect is obvious, and the raw material off-square prevention device prevents steel falling from occuring, effectively eradicates an off-square phenomenon, improves yield, reduces consumption of bearings, rollers and the like, meanwhile reduces the number of steel stacking and improves production efficiency.
Description
Technical field
The utility model belongs to the wire and bar mill technical field, particularly relates to the anti-off-square device of a kind of milling train raw material.
Background technology
Milling train is first procedure of steel billet through carrying out finished product processing after heating in thick, also can be described as the section of having finished blank and depresses.Steel billet goes out heating furnace and directly enters milling train by furnace delivery table, disconnected the cutting of card, finds that in rolling process the phenomenon of falling the steel often appears in outlet, and it is irregular to cause exporting the steel billet section, and finished product easily produces folding, and rejection number increases, and lumber recovery reduces; The section of blank is irregular simultaneously, and the axial force of importing and exporting the guide and guard deflector roll is strengthened, and causes deflector roll and damage of bearings, and has increased the rolling load of follow-up sortie, the situation of roll breakage and burn bearing occurs; The section inequality of the formation of falling the steel also can produce a lot of wire drawings and be retained in the guide and guard, has strengthened the possibility of heap steel.
Through on-the-spot trace analysis, to be original rolling-mill housing by the mill housing of two two frame-types connect the reason of finding to cause above-mentioned situation forms, and forms window in the framework, and roll is fixed in the memorial archway frame by bearing block.Because it is big that pass spreads the gradient of direction, make in that to spread direction little to the chucking power of steel billet, and cut and the milling train porch does not have guider in that card is disconnected, so cause the generation of above-mentioned situation.
Summary of the invention
The utility model provides a kind of milling train raw material to prevent the off-square device for solving the technical problem that exists in the known technology, this apparatus structure is simple, life cycle is long, and can effectively avoid the generation of the phenomenon of falling the steel, improve the quality of products and lumber recovery, minimizing heap steel takes place.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of milling train raw material is prevented the off-square device, includes the memorial archway frame, and the column of described memorial archway frame is provided with location-plate, and the entrance side of described memorial archway frame is provided with two groups of crossbeams, is connected with baffle plate between two groups of crossbeams, is connected with three groups of horn mouths on the described crossbeam in turn.
Described horn mouth is slot, and size is successively decreased along the rolling line direction, and its outer is chime.
Advantage and the good effect that the utlity model has are: the utility model is simple in structure, easy for installation, expense is few, has increased guiding and holding function that steel billet enters roll on the basis of original memorial archway shelf structure, and result of use is remarkable, not only avoided the generation of steel, stop the off-square phenomenon effectively, also improved lumber recovery, reduced the consumption of bearing, roll etc., also reduce the heap steel simultaneously, improved production efficiency.
Description of drawings
Fig. 1 is the utility model memorial archway shelf structure schematic diagram;
Fig. 2 is the utility model structural representation;
Fig. 3 is the horn mouth structural representation.
Among Fig. 1～Fig. 3,1. memorial archway frame, 2. crossbeam, 3. baffle plate, 4. location-plate, 5. horn mouth.
The specific embodiment
For further understanding content of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 2, a kind of milling train raw material is prevented the off-square device, include memorial archway frame 1, the two heel posts middle part of memorial archway frame 1 is separately installed with two guide plates as location-plate 4, connected by two groups of crossbeams 2 in the middle of entrance side two columns of memorial archway frame 1, be connected with baffle plate 3 by the mode of welding between two groups of crossbeams 2, form pass.Horn mouth 5 inserts and is installed on the memorial archway frame 1, is connected with crossbeam 2.Groove spacing according to roll designs three groups of horn mouths 5, horn mouth 5 is slot, size is successively decreased along the rolling line direction, and satisfy the requirement of billet size, the outer is designed for chimb, and three groups link to each other and to be installed on the crossbeam 5, horizontal direction by on the column two location-plates, 4 location, the crossbeam inboard is fixing by baffle plate 3, and skew appearred in horn mouth when preventing steel.4 directions produce the power that prevents from reversing to steel billet in upper and lower, left and right like this, have controlled the phenomenon of falling the steel effectively.
The utility model is simple in structure, easy for installation, expense is few, has increased guiding and holding function that steel billet enters roll on the basis of original memorial archway shelf structure, and result of use is remarkable, not only avoided the generation of steel, stop the off-square phenomenon effectively, also improved lumber recovery, reduced the consumption of bearing, roll etc., also reduce the heap steel simultaneously, improved production efficiency.
