Embodiment 1
[0033] The invention provides a processing technology for compressive high-carbon galvanized strip steel, comprising the following steps:
[0034] S1: at first prepare two strip steel blanks, carry out pickling to two strip steel blanks;
[0035] S2: the two steel strip blanks after the hydrochloric acid solution pickling are rinsed by clear water spray, after removing the residual acid on the surface, the steel strip blanks are dried by drying equipment;
[0036] S3: rolling the gauge block strip blank into 1mm thick prefabricated strip respectively by rolling mill;
[0037] S4: Carry out chemical cleaning to the prefabricated steel strip of gauge bar after rolling, use electrolytic cleaning agent to clean two strip steel blanks, place two prefabricated steel strips in the annealing furnace for annealing;
[0038] S5: Then unfold the two prefabricated steel strips and spread them flat on the workbench, take an appropriate number of reinforcing steel bars and place them on th...
Embodiment 2
[0047] The present invention provides a kind of processing technology of anti-pressure high-carbon galvanized strip steel, uses the electrolytic cleaning agent of DT-102CL in the step of chemical cleaning in the step S4, needs before carrying out chemical cleaning to strip steel, needs in alkali Prepare the free alkali concentration in the liquid pre-mixing tank at 100g / l and the temperature at 40°C. In the cleaning step, the free alkali concentration is 2g / l, the iron powder is 150ppm, the temperature is 40°C, the oil content is controlled at 200ppm, and nylon fiber brush rollers are used. Brushing the steel strip, the direction of rotation of the brush roller is opposite to that of the steel strip, in the electrolytic cleaning step, the free alkali concentration is controlled at 10g / l, the temperature is 65°C, and the oil content is controlled at 500ppm. In particular, it can also be used in the step S10 The processing method of carrying out hot-dip galvanizing to the reinfor...
Embodiment 3
[0049] The present invention provides a processing technology for high-pressure galvanized strip steel, wherein the reinforcing steel strips A in the step S5 are vertically arranged on the upper end of the prefabricated strip steel, and the reinforcing steel strips A are The spacing is the same, the reinforcing steel bars B in the step S7 are arranged vertically parallel to each other on the upper end of the compressive strengthening plate, the spacing between the reinforcing steel bars is the same, the reinforcing steel bars B are the same as the reinforcing steel bars A in the step S5 The mutual dislocation is arranged between, and described reinforced steel bar A and described reinforced steel bar B all adopt high tenacity 65MN steel bar, and in described step S1, two strip steel blanks all drop into the hydrochloric acid solution that concentration is 90g / L to carry out Pickling, the annealing temperature of the two prefabricated steel strips in the step S4 is controlled at...
