Technical Field
The utility model relates to a hot spraying especially relates to an adjustable wire rod spray gun.
Background
Thermal spraying is to heat and melt a coating material, atomize the coating material into ultrafine particles by a high-speed gas flow, and spray the ultrafine particles onto the surface of a workpiece at a high speed to form a coating. Different coating materials are selected according to requirements, and one or more performances of wear resistance, corrosion resistance, oxidation resistance, heat resistance and the like can be obtained.
The prior art generally uses oxy-acetylene as a heat source, but oxy-acetylene flames can be classified into three types according to the ratio relationship between oxygen and acetylene gas: neutral flame, oxidizing flame, and carbonizing flame.
The neutral flame is flame generated by burning the mixture of oxygen and acetylene in equal amount or with the oxygen content slightly larger than the acetylene content. The inner flame zone of the flame is substantially free of free oxygen and free carbon, and the carbon monoxide and hydrogen produced by combustion react with the molten base metal to reduce the oxides.
And the oxidizing flame is flame generated by mixing and combusting the mixture with oxygen content larger than acetylene content. Free oxygen, carbon dioxide and water vapor exist in the inner flame and the outer flame of the flame, and pores and oxide slag inclusion are easily generated in a welding line.
The carbonization flame is flame generated by mixing and burning the mixture with oxygen content less than acetylene content. Because the oxygen content is low, the acetylene is not enough to be completely combusted, the excessive acetylene is decomposed into carbon and hydrogen, and the free carbon can permeate into the molten pool to carburize a welding line; hydrogen enters a molten pool, and pores and cracks are easily generated on a welding line.
