Manufacturing method of high-strength galvanized steel sheet

Abstract

The invention belongs to the technical field of iron-based alloys, and particularly relates to a high-strength galvanized steel sheet manufacturing method.The high-strength galvanized steel sheet manufacturing method comprises a galvanizing device, adjusting devices are slidably connected to the left side and the right side of the upper portion of the outer surface of the galvanizing device, pressure devices are arranged on the lower portions of the inner walls of the adjusting devices, and the galvanizing device comprises an electrolytic tank; a penetrating rotating opening is formed in the middle of the lower portion of the inner wall of the electrolytic tank, the lower portion of the inner wall of the electrolytic tank is fixedly connected with a vertical guide shell through the penetrating rotating opening, and a threaded rotating groove is formed in the inner wall of the vertical guide shell. Compared with a common steel plate, the anti-pressure capacity and toughness of the device are improved through the rock wool sandwich layer in the galvanized steel plate sleeve, when the galvanized steel plate sleeve on the outer layer is impacted, the rock wool sandwich layer on the inner layer can effectively absorb the impact force, the impact force borne by the other side of the galvanized steel plate sleeve is greatly reduced, and the service life of the device is prolonged. And therefore, the impact resistance of the galvanized steel sheet is relatively high.

Description

technical field [0001] The invention belongs to the technical field of iron-based alloys, in particular to a method for manufacturing a high-strength galvanized steel sheet. Background technique [0002] The rapid progress of science and technology and the improvement of people's material living standards on a global scale have directly led to the depletion of existing energy sources. The energy problem has become one of the major themes in today's world. Before an effective new alternative energy breakthrough has been achieved, energy conservation has been put on the agenda of all countries in the world. Among them, building energy consumption, which accounts for about one-fifth of the total energy consumption, has attracted widespread attention from the society. More than half of my country's total steel production is used in the construction industry. Improving the use efficiency of construction steel can play a significant role in saving energy and reducing energy consum...
