Description

TECHNICAL FIELD [0001] The present invention relates to a device for preventing non-coupling of a molded-

More particularly, the present invention relates to a non-dynamism prevention apparatus for a molding machine for preventing the occurrence of defects in the quality of a blanket caused by a rolling tire treading phenomenon occurring during the production of a blanket by the FINEX method, ≪ / RTI >

In general, the FINEX steelmaking method reduces the ORE FINE (ORE FINE), which is not a high-quality compacted iron ore, which is exhausted by environment-friendly steelmaking method that does not generate CO ₂ emission compared to the existing blast furnace process, It is used as a raw material by making it compact in HCI (Hot Compacted Iron) process, and it produces molten carbonate which is massive in the COAL BRIQUETTING process of the coal in spectral form and charges it into a melting furnace to produce molten iron It is a replacement method to replace the blast furnace.

In this re-forming process, the compacting process is carried out by supplying coal in a pulverized state from a GRAVITY FEEDER to a molding machine fixed roll and a floating roll tire shaft assembly (TIRE SHAFT ASS) assembled into a plurality of shafts and a plurality of roll tires ROLL TIRE 'Y) is compressed and passed through a rotary motion to produce a massive coal from the coal in the spectral state by the shape of a pocket (POCKET) processed on the outer circumferential surface of the roll tire combined with a plurality of sets , And the pocket shape for manufacturing the briquettes is divided by 1/2 for each of the roll tires (ROLL TIRE), so that the two rolls (ROLL) are rotated to produce the molded bins tuned in one form.

Conventionally, thrust is generated in the circumferential direction and the axial direction of the roll tire during the production of the molded tire. However, the circumferential thrust is transmitted through the shaft and the roll tire key binding during assembly of the shaft and the roll tire, However, the thrust in the direction of the shaft is restricted only by the tolerance of the roll tires and the shaft, and the overhang, the rolling tire and the shaft tolerance are widened by the loosening of the shaft tolerance, so that the pocketing of the molded- The quality of the coal is increased, the cracking is generated, the compressive strength is lowered and the quality of chips (CHIP) is increased. In terms of facilities, there are problems such as cost increase of expensive roll tires and early replacement of shafts Life had been.

In addition, a roll tire stopper device for preventing a phenomenon of being merely sideways pushed outside of the fixed roll is provided. Since the conventional roll tire stopper device is composed of a single body, in order to replace the roll tire stopper if necessary, Therefore, there is a problem that the replacement operation time is increased correspondingly, and thus the quality of the production of the briquette is deteriorated and the productivity is lowered.

The present invention prevents the phenomenon in which the roll tire is pushed outward in the shaft direction by the axial thrust during the production of the shaped carbon by using a molding machine for manufacturing the compacted material through compression between the two rolls to form the compacted material, And to provide an apparatus for preventing unmodulation of a molded-in-carbon manufacturing facility that can take measures in a short time when wear and deformation of parts occur.

According to one embodiment of the invention, there is provided a stationary roll shaft assembly comprising at least a pair of stationary rolls rotated by a stationary roll shaft,

A flow roll shaft assembly including at least a pair of flow rolls rotated by a flow roll shaft while making a set with the fixed roll,

A fixed roll tire and a floating roll tire which are respectively provided on the outer side of the fixed roll and the floating roll,
