Problems solved by technology

[0007] In order to overcome the inadequacy of existing solutions that cannot solve the data collection of field equipment terminals, the present invention provides a processing technology for high-pressure galvanized steel strips. The present invention can realize the optimization of the processing technology for strip steel, and Introduce reinforced steel strips and compression reinforced plates to strengthen the strip steel, innovatively adopt the double-layer galvanized strip steel method and realize the integrated connection between the reinforced steel strips, the strip steel, and the compression reinforced plate, with high connection strength , it is not easy to peel off, and at the same time, the compressive strength of the double-layer steel strip and the double-layer reinforced steel bar is greatly increased, thereby significantly improving the quality of the strip steel and the compressive strength of the strip steel. The mechanical strength meets the long-term use in complex environments. The technical solution of the present invention adds a chemical cleaning process in the middle of the two annealing processes. Through the control of the solution, the surface of the strip is effectively cleaned, and the two Carbon deposit defects on the surface of secondary annealing effectively improve the quality of strip products

Abstract

The invention relates to the technical field of strip steel processing, in particular to a processing technology of compression-resistant high-carbon galvanized strip steel. The processing technology comprises the following steps of firstly, preparing two strip steel blanks, and conducting acid pickling on the two strip steel blanks; washing the two strip steel blanks subjected to acid pickling through a hydrochloric acid solution through clean water in a spraying mode, and after residual acid on the surfaces is removed, drying the strip steel blanks through drying equipment; rolling the two strip steel blanks into prefabricated strip steel with the thickness of 1-2.5 mm through a rolling mill; and conducting chemical cleaning on two rolled prefabricated strip steel, cleaning the two strip steel blanks by using an electrolytic cleaning agent, placing the two prefabricated strip steel in an annealing furnace for annealing, then unfolding the two prefabricated strip steel, flatly laying the two prefabricated strip steel on the workbench, and placing a proper number of reinforcing steel bars at the upper end of one of the prefabricated strip steel. According to the processing technology, the quality and the compressive strength of the strip steel can be effectively and stably enhanced remarkably, the mechanical strength of the strip steel can be greatly improved, and the strip steel can be used for a long time in a complex environment.

Description

technical field [0001] The invention relates to the technical field of strip steel processing, in particular to a processing technology for compressive high-carbon galvanized strip steel. Background technique [0002] At present, strip steel is a narrow and long steel plate produced by various steel rolling enterprises in order to meet the needs of industrialized production of various metal or mechanical products in different industrial sectors. Strip steel, also known as steel strip, is within 1300mm in width, and the length is slightly different according to the size of each coil. According to the quality of the steel, it is divided into high-quality and ordinary strip steel; according to the rolling method, it is divided into hot rolling and cold rolling. , respectively called hot-rolled strip and cold-rolled strip. The thickness of common hot-rolled steel strip is 2mm to 6mm, and that of cold-rolled steel strip is generally 0.05mm to 3.60mm. Strip steel can be made of ...
