Abstract
The invention provides a method for electrolytic polishing of an inner wall of a kettle. The method is characterized in that electrodes are arranged in a kettle and an electrolyte is added into the kettle; and under the action of a power supply, an electrolyte-based polishing process is carried out so that electrolytic polishing of an inner wall of the kettle is realized. The method can improve efficiency of electrolytic polishing of the inner wall of the kettle, realize good flatness and high surface glossiness and reduces a cost. The method is suitable for electrolytic polishing of an inner surface of a kettle.
Description
Technical field
The present invention is to provide the inner wall of kettle finishing method of oil, chemical industry, chemical fertilizer, field of medicaments use, specifically a kind of inner wall of kettle electrolytic polishing method.
Background technology
Electropolishing is that applied metal surface selectivity anode in electrolytic solution melts and reaches polishing and a kind for the treatment of process of smooth appearance.When handling, by the control to current density, electrolytic solution viscosity and electrolyte temperature, metal is melted in electrolytic solution, pocket enters passive state and melts, and the boss activity melts, and finally reaches certain balance, by adding light agent and anodic polarization effect in the electrolytic solution, reach the purpose of leveling polishing, surface brightness can reach extreme value.Main electropolishing mechanism has the theoretical and passive film theory of mucous membrane.The smoothness of metallic surface electropolishing and thick liquid film are closely related, and luminance brightness and solid passive film are closely related.The metallic surface electropolishing can be subdivided into macroscopic view leveling and two processes of microcosmic leveling, and the variation of these two processes and anode potential is closely related, and when it reached a kind of dynamic balance state, surface brightness can reach extreme value.Compare with mechanical polishing, electropolishing can reduce the stress on metal inside and surface, and the smooth finish behind the electropolishing and planeness keep more for a long time than mechanical polishing.
At present, along with the continuous development of domestic and international electropolishing technology, the research of domestic electropolishing technology to metal works is more and more ripe, but can't realize the disposable integral electropolishing of cylindrical kettle and ellipsoidal head, especially main equipment does not have correlation technique at home as yet.
Summary of the invention
In order to realize the inner wall of kettle polishing, the present invention proposes a kind of inner wall of kettle electrolytic polishing method.This method be by will electrolytic solution pumping in the kettle after the heating, and feed direct current between pole plate and electrode axis, by the effect of electric current and the electrolytic reaction between pole plate and the electrode axis, solve the technical problem of inner wall of kettle electropolishing.
The scheme that technical solution problem of the present invention adopts is:
Electropolishing equipment: kettle is installed on the carrying roller of the commentaries on classics jar machine that drive-motor is housed, and the kettle rotation axis is installed on the support at kettle two ends; Insulcrete is housed in kettle, at insulcrete pole plate is arranged fixedly, in the kettle centre electrode axis is arranged fixedly; Kettle one end is provided with the electrolytic solution storage tank, in a side of electrolytic solution storage tank temperature control unit is housed, and is provided with transferpump in a side of electrolytic solution storage tank, and transferpump is communicated with second mouth of pipe by pipeline, at pipeline under meter is housed; Be provided with first mouth of pipe at the kettle opposite side; Be provided with housing at the kettle opposite side, housing is connected with direct supply by lead, and direct supply is connected with electrode axis with pole plate respectively by first mouth of pipe, constitutes the electrolysis loop.
Electrolytic polishing method: the electrolytic solution for preparing is poured in the electrolytic solution storage tank, starting temperature control unit heats electrolytic solution, after electrolyte temperature reaches the design temperature scope, starting transferpump pumps into electrolytic solution in the electrolytic solution storage tank, start housing and power supply, change the drive-motor of jar machine and start working, rotate kettle and make electrolytic solution in still, carry out the electropolishing reaction.
