Description
Technical Field
The invention belongs to the technical field of high-strength steel member preparation, and particularly relates to a complete tool for thermal spraying corrosion prevention of a high-strength steel member and a thermal spraying method.
Background
The hot spraying corrosion prevention of the steel member is that zinc wires, aluminum wires or zinc-aluminum wires are heated to a molten or semi-molten state through flame or electric arc, atomized to form atomized particles by means of the power of flame flow or externally added high-speed airflow, the atomized particles are sprayed to the surface of the pretreated steel member at a certain speed, and the atomized particles are combined with the surface of the steel member to form a coating with high-efficiency corrosion resistance. Most of atomized particles in the thermal spraying process can adhere to the outer surface of a steel member to be thermally sprayed to form an anticorrosive coating, and the atomized particles adhering to the outer surface of the steel member to be thermally sprayed are effective atomized particles; and a small part of atomized particles cannot form a required anticorrosive layer due to the self restriction of the spraying process, and the part of atomized particles are ineffective atomized particles which firstly fly in the thermal spraying environment and finally adhere to the surfaces of other equipment and articles in the thermal spraying environment. Thermal spraying corrosion prevention is excellent in corrosion resistance, so that steel members applied to a heavy corrosion environment are increasingly subjected to thermal spraying corrosion prevention technology. Although thermal spray techniques and processes are well established and thermal spray corrosion protection is highly recognized by the industry, there are a number of disadvantages to the thermal spray process that need to be overcome and enhanced: firstly, the ineffective atomized particles generated in the thermal spraying process not only pollute the environment, but also easily cause explosion accidents after the ineffective atomized particles reach a certain concentration, so that the unordered flying of the ineffective atomized particles in the thermal spraying process needs to be controlled, and the ineffective atomized particles are orderly removed in time to reduce the concentration of the ineffective atomized particles so as to avoid the explosion accidents, and are recycled; secondly, the invalid atomized particles generated in the thermal spraying process can be strongly adhered to the surfaces of the parts of the operating equipment existing in the thermal spraying environment, so that the operating equipment is damaged, and therefore the operating equipment used in the thermal spraying environment needs to be reliably sealed and protected to avoid the adhesion damage of the invalid atomized particles; and thirdly, local non-spraying areas often appear on the steel member needing thermal spraying corrosion prevention, the local non-spraying areas are mainly used for subsequent welding connection forming parts, and the spraying particles are adhered to the welding connection forming parts to greatly influence the quality of subsequent welding operation, so that the appearance of the non-spraying areas needs to be reliably covered and sealed, and the spraying particles are prevented from being adhered to the appearance of the non-spraying areas of the steel member to be sprayed.
