Embodiment 1
[0037] Select low-carbon cold-rolled steel according to the shape of the cooker and process it into a semi-finished cooker according to the existing method of processing cooker, and then place the semi-finished cooker in a degreasing agent with a temperature of 60°C to remove oil for 60 minutes, wherein the degreasing agent The weight percent of each composition is: NaOH: 6%; Na 2 CO 3 : 6%; Na 3 PO 4 : 4% Na 2 SiO 3: 0.5%; Surfactant: 0.1%; the rest is water; the above semi-finished product after degreasing is placed in a hydrochloric acid solution with a mass fraction of 15% at room temperature for 10 minutes. Add the corrosion inhibitor hexamethylenetetramine that accounts for about 1% by weight of the hydrochloric acid solution into the hydrochloric acid solution. After the rust removal is completed, put the semi-finished cooker into a 1% tyrosine solution by mass fraction, passivate it for 5 minutes, and then Rinse 2 to 3 times with cold water at 20°C, and dry immedi...
Embodiment 2
[0040] Select low-carbon hot-rolled steel according to the shape of the cooker and process it into a semi-finished cooker according to the existing method of processing cooker, and then place the semi-finished cooker in a degreasing agent at a temperature of 70 ° C for 20 minutes, wherein the degreasing agent The weight percent of each composition is: NaOH: 10%; Na 2 CO 3 : 3%; Na 3 PO 4 : 2% Na 2 SiO 3 : 2%; Surfactant: 0.05%; The rest is water; the semi-finished product after degreasing is placed in the hydrochloric acid solution with a mass fraction of 17% under room temperature for 8 minutes for derusting. Add the corrosion inhibitor hexamethylenetetramine that accounts for about 1% of the weight percentage of the hydrochloric acid solution in the hydrochloric acid solution. After the rust removal is completed, put the semi-finished cooker into the 2% tyrosine solution for passivation for 3 minutes, and then Rinse 2-3 times with cold water at 25°C, and dry immediately...
Embodiment 3
[0043] Alloy steel material is selected according to the shape of the cooker and processed into a semi-finished cooker according to the existing method of processing cooker, and then the semi-finished cooker is placed in a degreasing agent at a temperature of 80 ° C for 30 minutes, wherein the components in the degreasing agent The weight percentage is: NaOH: 8%; Na 2 CO 3 : 5%; Na 3 PO 4 : 3% Na 2 SiO 3 Surfactant: 1%; Surfactant: 0.02%; The rest is water; Place the above-mentioned semi-finished product after degreasing in a hydrochloric acid solution with a mass fraction of 18% at room temperature for 5 minutes. Add the corrosion inhibitor hexamethylenetetramine accounting for about 1% by weight of the hydrochloric acid solution in the hydrochloric acid solution. After the rust removal is completed, put the semi-finished cooker into a 3% tyrosine solution by mass fraction, passivate it for 2 minutes, and then Rinse 2-3 times with cold water at 2°C, and dry immediately a...
