Description

Oriented silicon steel brush roll cleaning assembly

Technical Field

The utility model relates to a belted steel annealing equipment technical field, concretely relates to oriented silicon steel brush roll washs subassembly.

Background

The strip steel cleaning step is one of the main steps of the continuous annealing of the oriented silicon steel, and aims to brush off the magnesium oxide coating on the surface of the strip steel. The conventional brush roller has the following technical defects when in use: belted steel lasts the feeding, the brush roll is rotatory under actuating mechanism's drive, the brush hair and the belted steel of brush roll fully contact, because belted steel thickness is less itself, because the horizontal deviation can appear in belted steel feeding, belted steel both sides limit is to shearing rather than the brush hair of laminating, brush hair length after the shearing equals the interval of brush roll and belted steel, can not form roof pressure brush sweep structure between brush hair and the belted steel, the quantity of brush hair is too much by the shearing of long-time back side department, it is not good to lead to the magnesium oxide brush of belted steel side to remove the effect, under the not high condition of belted steel precision of rectifying, can lead to having the remaining belted steel side width increase of magnesium oxide, and then influence the.

Detailed Description

The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

Segmenting of brush rolls

The known brush roll comprises a rolling brush section of a brush roll and allowance sections positioned at two ends of the rolling brush section, wherein the rolling brush section and the surface of strip steel are pressed and rubbed with each other in a strip steel cleaning state, and the allowance sections are used for ensuring that the strip steel can still be contacted with bristles after being transversely offset.

Guide comb for brush hair

The bristle guide comb functions to guide the bristles, and the extending direction of the comb teeth determines the deformation direction of the bristles. In actual use, the brush hair guide comb guides the brush hair to the surface of the strip steel from the outer side of the side edge of the strip steel. The broach size of brush hair direction comb does not have special restriction, and the broach trend is little controlled and is helped the evenly distributed of brush hair, avoids the brush hair too concentrated, and the broach interval is in order to satisfy the continuous direction of brush hair to avoid appearing the brush hair card between the broach or damage the brush hair as the standard.

The free ends of the comb teeth are positioned on the feeding side of the roller gap, so that the bristles separated from the free ends of the comb teeth can be pressed against the strip steel.

The length of the bristle guide comb along the axial direction of the brush roller depends on the deviation correction precision of strip steel feeding: the deviation rectification precision is high, and the length of the bristle guide comb along the axial direction of the brush roller is controlled to be reduced; the deviation rectification precision is low, and the length of the brush hair guide comb along the axial direction of the brush roller is controlled to be increased.

Connection mode of brush hair guide comb and machine frame

The brush hair guide comb is fixedly connected with the machine frame, namely the deformation amount and the deformation direction of the brush hair are consistent all the time, and the specific size of the brush hair guide comb is comprehensively determined according to the length of the brush hair, the distance between the brush roll and the strip steel and the transverse offset of the strip steel feeding.

The brush hair direction comb passes through broach angle of inclination adjustment subassembly with the frame and is connected, and then the deflection of brush hair is adjustable, and is general, and belted steel skew direction is opposite with the broach tilt motion direction of brush hair direction comb: the offset of the strip steel along the horizontal x1 direction is increased, the bristle guide comb guides the bristles to the side opposite to the offset direction of the strip steel, the deformation of the bristles is increased, and the number of the bristles in dynamic friction with the edge of the strip steel is increased based on the actions; conversely, the deflection of the strip in the direction opposite to the direction X1 reduces the deformation of the bristles driven by the bristle guide comb.

The comb-tooth inclination-angle adjusting assembly is used for adjusting the inclination angle of the comb teeth, and comprises a known structure which satisfies the above functions. Preferably, the bristle guide comb is adjusted by adopting a linear hydraulic telescopic rod, so that the adjusting effects of quick response and high accuracy are achieved.

The bristles are made of nylon filament containing silicon carbide abrasive material as described in CN209020807U, and the density is up to 13300 filaments/m²Preferably, the bristles are divided smoothly by spindle-shaped comb teeth.

The brush hair guide combs are arranged on two sides of the roller gap of the brush roller, so that the front and the back of the edge of the strip steel can be fully cleaned, the defect caused by incomplete removal of magnesium oxide is reduced, and the yield of the oriented silicon steel is improved.
