The invention discloses an aluminum zinc silicon steel plate, and belongs to the technical field of a raw material base plate of a color coating steel plate. The aluminum zinc silicon steel plate is characterize in that the coating material on the surface of the plate body of the aluminum zinc silicon steel plate comprises the following components by the weight percentage: 40% to 45% of aluminum, 1.2% to 1.4% of silicon, and zinc in balancing amount. The steel plate has the advantages that (1) the surface planeness is excellent and the microstructure is uniform; (2) the required bath temperature reduces from 600 to 650 DEG C in the prior art to 585 to 588 DEG C, so as to realize energy conservation; (3) the adhesive force to the surface of the coating layer is strong, the cutting protection is good, and the salt spray resistant experiment increases from 500h in the prior art to 650 to 678h; (4) only a film layer with 4 Mum can effectively cover crystal pattern on the surface of hot-dip coating layer; (5) the amount of produced plating pot slag is small, only accounting for 1% to 3% of the coating layer material and 15% of the prior art; (6) the nodulation of the roller in the plating pot is in a lower degree and a shovel roller is not needed; and (7) the service life of the plating pot sensor can reach 3 years, comparatively, the service life is only 1 year in the prior art.
