The working principle of the utility model is as follows: firstly placing two ends of a used furnace roller on a fixed plate, turning over anchor clamps, screwing bolts to fix the furnace roller on the fixed plate, driving a motor to enable a sliding block to move to one end, opening a lower brush ring, driving an electric cylinder to enable the brush ring to be in the same circle center as the furnace roller, turning over the lower brush ring to enable the brush ring to be sleeved on the furnace roller, penetrating bolts at one ends of an upper brush ring and a lower brush ring, screwing nuts below the upper brush ring, closing the upper brush ring and the lower brush ring to form a circular ring, opening a water pump to enable water to be sprayed on the furnace roller, and driving the motor to enable the sliding block to move left and right to drive the brush ring to brush back and forth on the furnace roller.
Foreign matters falling on the roll surface, such as metal powder floating in the furnace atmosphere and iron powder generated by the speed difference between the strip steel and the furnace roll, are extruded by the strip steel and the furnace roll and then adhere to the roll surface to form adhesive knots. The initial stage of the adhering nodules may be removed by grinding the furnace roller.
The other kind is that the reaction type nodulation is formed, the iron powder which is left on the strip steel and is carried into the furnace to be free, the iron powder which is rubbed with the furnace roller to fall off from the surface of the strip steel, and the FeO, mnO, siO which is formed by the elements such as Mn, si and the like and the residual oxygen of the protective atmosphere are contained in the high-strength strip steel 2 Al coated with furnace roller 2 O 3 Eutectic, eutectic products have low melting point and good adhesion, and pores are preferentially gathered on the situation of the surface coating of the furnace roller and the roller body to form furnace roller nodulation. Cr-Ni of the furnace roller base material has strong affinity and intersolubility with the eutectic and is easy to adhere to the roller surface, and the Cr-Ni of the furnace roller base material and the base material of the furnace roller are subjected to chemical reaction at the high temperature of more than 800 ℃ to form hard-to-remove knots.
The cold rolled steel has higher Mn and Si content and can react chemically better than Fe in a furnace to generate MnO and SiO 2 。2Fe 3 O 4 +6Mn+Si＝6MnO+SiO 2 +6Fe
MnO、SiO 2 And Al 2 O 3 Eutectic compounds with low melting points are the main cause of the high-strength strip steel to generate nodulation. When the working condition of the furnace roller coating is poor in the high-temperature working environment, the adhesion type nodulation can be partially converted into a reaction type nodulation. Whichever type of nodulation is experienced, the two processes of forming the tumor nuclei and growing the agglomerates appear morphologically strippable layer by layer. When the formed tumor-shaped objects and the roller surface are slightly melted, diffused and alloyed, part of the tumor-shaped objects firmly adhere to the roller surface and become damages of scratch and roller mark, namely 'pitting' defects; the other part of the nubs fall off and adhere to the surface of the strip steel after being melted to form a defect of 'foreign matter pressing in'. And brushing to remove residual emulsion, iron powder and the like on the surface of the strip steel after acid rolling.
The surface residues of the acid-rolled chilled rolls are generally 300-500 mg/m 2 After cleaning, the surface of the strip steel still has residues of 25mg/m 2 The cleaning effect of the strip steel is good, and the cleaning of the atmosphere in the furnace can be ensured to play a key role in the cleaning production in the continuous annealing furnace.
Poor cleaning effect is expressed:
the first step, after cleaning, the surface of the strip steel still has more residual iron powder and greasy dirt, and the strip steel is brought into a furnace to be rubbed and extruded with a furnace roller, and gradually accumulated and deposited on the surface of the strip steelThe RTF high temperature section of the furnace roller and the inner lining plate surface is particularly obvious; secondly, the main components of the strip steel which are cleaned, such as the cleaning liquid still remained are NaOH and Na + 、OH - The white spots formed on the surface of the strip steel are carried into the furnace to deposit on the surfaces of the furnace roller and the lining plate, and the inter-crystal corrosion action of the lining plate is generated to corrode the surface coating of the furnace roller to induce the damage of the coating.
The spray pipe 64 sprays water firstly to clean the steel slag and the emulsion, and then sprays NaOH to generate Al 2 O 3 +2NaOH＝2NaAlO 2 +H 2 O, thereby cleaning the accretion on the surface of the furnace roller.
