Technical Field
The invention relates to a laser cladding alloy material, in particular to an alloy material for manufacturing a mill housing laser remanufacturing of a steel mill and a preparation method thereof.
Technical Field
Rolling mill housing, also called stand, is an important part of two metal frames for mounting bearing assemblies such as rolls, backup rolls and roll adjustment devices. The mill housing is continuously impacted by rolling force in the running process, so that abrasion is generated between the lining plate and the mill housing mounting matching surface, meanwhile, the rolled cooling water can cause corrosion of the mill housing surface, the rolling precision is reduced, and the rolling quality of the steel is reduced.
At present, the main repair modes of the housing are modes of on-line overlaying, thermal spraying, laser cladding and the like. Along with the development of laser additive manufacturing technology, a laser cladding mode is becoming a main method for repairing a mill housing, but laser manufacturing and remanufacturing materials for the housing at present mainly have high hardness, cracks are easy to occur in the cladding process, the machining difficulty is high after cladding, even the machining cannot be performed, only manual polishing can be relied on, the working efficiency is greatly reduced, and the working difficulty is improved.
Disclosure of Invention
The invention mainly aims at the problems, and provides a laser manufacturing and remanufacturing alloy material and a preparation method thereof after repeated researches and a large number of experiments. The alloy material takes the cobalt-based alloy as a matrix, and proper Ti element is added to reduce the problem of larger air holes which are easy to occur in the alloy layer after cladding; la element is added, the strength of the cladding layer is improved, the adhesive force of the material oxide film is improved, and the corrosion resistance of the cladding layer is improved; the proportion of Ni, cr and W is controlled to ensure the wear resistance of the cladding layer in the use process, the hardness of the cladding layer is controlled, the cladding property is improved, and the processing difficulty is reduced.
In order to achieve the above purpose, the present invention adopts the following technical scheme.
An alloy material for a mill housing for laser manufacturing and remanufacturing comprises the following components in percentage by mass:
c:0.7% -1.2%, cr:22% -27%, fe:1% -3%, W:4% -8%, ni:5% -10%, ti: 0.5-1.0%, lanthanum oxide: 0.1% -0.5%, co: the balance.
The preparation method of the mill housing for laser manufacturing and remanufacturing comprises the following specific steps:
(1) And removing the fatigue layer and oxide on the surface of the housing to be clad.
(2) The laser cladding technology is selected, the synchronous powder feeding or the preset powder spreading mode is adopted for scanning, the single-layer cladding thickness of the cladding layer is 0.5-1.0mm, and the cladding layer alloy material comprises the following components: c:0.7% -1.2%, cr:22% -27%, fe:1% -3%, W:4% -8%, ni:5% -10%, ti: 0.5-1.0%, lanthanum oxide: 0.1% -0.5%, co: the balance.
The parameters of the laser cladding technology are as follows: the preheating temperature is 200 ℃, the powder feeding amount is 10g/min-50g/min, the laser power is 3kw-4kw, the light spot diameter is 4.0mm, the scanning speed is 1000mm/min-2000mm/min, the step is 2.0mm, the lap joint rate is 40-60%, and the single-layer cladding thickness is 0.5mm-1.0mm.
Compared with the prior art, the invention has the beneficial effects that.
(1) The cladding thickness is strictly controlled to be 0.5-1.0mm, so that the phenomenon that air holes in the cladding layer cannot escape due to too fast solidification due to too thick cladding layer thickness is avoided.
(2) Ti removes oxygen in the powder and oxygen in the cladding process so as to reduce air holes in the cladding layer, avoid penetrating air holes, prevent the cladding layer from being corrosion-proof, further improve the corrosion resistance of the surface of the housing, and simultaneously compensate for carbide reduction caused by reduction of Cr content and ensure the wear resistance in the use process; and meanwhile, the carbide with the size smaller than 2 microns is formed in the cladding process, so that the carbide can be used as a nucleation point, fine grains and improve the impact resistance of the cladding layer. However, the carbide forming capability of Ti is strong, the adding amount needs to be controlled accurately, otherwise, the C supply of other elements in the matrix is insufficient, and the effective strengthening effect on the cladding layer cannot be achieved.
(3) The addition of lanthanum oxide improves grain boundary, reduces segregation of carbide, improves deoxidizing and desulfurizing capacity, and the generated rare earth oxysulfide can generate good dispersion strengthening effect; the adhesion capability of the oxide film is improved, and the corrosion resistance of the cladding layer is improved. However, the amount of the additive should be strictly controlled, otherwise the opposite effect is generated, and serious non-uniformity of the tissue is caused.
(4) The proportion of Ni, W and Cr is reasonably controlled. As the corrosion of the working condition of the housing is mainly water vapor corrosion, the corrosion resistance can be ensured by controlling the Cr content to be 22-27%, and a certain amount of carbide can be formed without greatly reducing the wear resistance. The W content is properly controlled, so that inconvenience for subsequent processing caused by excessive carbide is avoided, meanwhile, the cracking tendency in the cladding process is reduced, and the toughness of the cladding layer is improved. The addition of Ni improves the stability of austenite, reduces the hardness of a cladding layer, controls the hardness of the cladding layer to be 38-46HRC, improves the cladding performance of the material, and reduces the processing difficulty after cladding.
