4017 aluminium alloy checkered plates

Ordinary checkered plates are mostly processed with 1060, 3003, and 5052 aluminum alloys in 1 series, 3 series, and 5 series as the plate base, and 4 series aluminum alloys are rarely used as the plate base. In comparison, the 1-series and 3-series aluminum alloy checker plates have lower hardness and slightly poorer wear resistance, and are mostly used for rust prevention in ordinary environments and applications where the requirements are not strict. Although the 5 series aluminum alloy pattern plate has better corrosion resistance, the anodization effect is slightly worse than that of the 6 series aluminum alloy. The 4-series aluminium alloy checker plate has particularly good wear resistance and good anti-skid ability. It is usually used as building materials and manufacturing decorative parts, such as traffic, building floors, truck compartments, cold storage, elevators and other anti-skid plates and screen skeletons and other packaging and decoration materials.



4017-H2X state aluminum alloy checker plate and preparation method thereof, the 4017-H2X state aluminum alloy checker plate has a certain hardness, good wear resistance, no naked cracks after 90° bending, no orange peel texture, and fine surface , Can be painted, suitable for building materials and manufacturing decorative parts, such as transportation, building floors, truck compartments, cold storage, elevators and other anti-skid plates and screen skeletons and other packaging and decorative materials.
 
4017-H2X state aluminum alloy checker plate is characterized in that, it is composed of the following raw materials by weight percentage: Si0.6～1.6%, Fe≤0.7%, Cu 0.1～0.5%, Mn 0.6～1.2%, Mg 0.1～0.5% , Zn≤0.2%, other single impurities <0.05%, total impurities <0.15%, and the balance is Al;
The preparation method of 4017-H2X state aluminum alloy pattern plate, comprises the following steps:
Step 1: batching according to the composition of the raw materials and smelting and casting;
Step 2: Soaking the ingot, machining the milling surface;
Step 3: hot-rolling to a hot-rolled billet with a thickness of 6.0-10.0 mm;
Step 4: Cold-rolling and billeting: cold-rolling and billeting the hot-rolled billet, and cold-rolling the billet with a total reduction of not less than 40%, the rolling thickness is 2.1mm to 5.1mm, and the cold rolling rolling oil The refractive index is greater than 90%, and the kinematic viscosity value at 40℃ is 2.2～2.4mm²/s;
Step 5: cold rolling and embossing: use patterned rollers to perform cold rolling and embossing with a processing rate of 20% to 50%, and the cold rolling and embossing speed is 70 to 180 m/min;
Step 6: Continuous annealing: The embossed patterned plate strip is cleaned, and then rapidly annealed in a continuous annealing furnace. The temperature of the continuous annealing furnace is set between 350 ° C and 410 ‘C, and the strip running speed is set at 2 ~8 m/min, water-cooled, dried, straightened and rolled after being baked;
Step 7: Tensile straightening or cross-cutting: The continuously annealed aluminum alloy checkered plate is drawn and straightened or cross-cut into corresponding coils or sheets.
