Abstract
The invention belongs to the technical field of metallurgy, and particularly relates to a process for improving flatness of a metal plate. The process for improving the flatness of the metal plate is characterized by comprising the steps that firstly, the metal plate is ground and polished; secondly, a low-concentration hydrochloric acid solution coats the surface of the ground and polished plate; thirdly, the metal plate obtained in the second step is heated to 800 DEG C; fourthly, the heated metal plate is immersed into the hydrochloric acid solution for 30 minutes; fifthly, the cast iron plate is taken out to be ground and polished for the second time.
Description
Technical field
the invention belongs to metallurgical technology field, particularly a kind of technique that improves sheet metal flatness.
Background technology
single to the process of the surperficial polishing of sheet metal in prior art, effect is poor.
Summary of the invention
for the deficiencies in the prior art, the invention provides a kind of technique that improves sheet metal flatness.
Technical scheme of the present invention is a kind of technique that improves sheet metal flatness, it is characterized in that: a kind of processing step that improves sheet metal flatness is as follows:
The first step: sheet metal is carried out to sanding and polishing;
Second step: the plate surface after sanding and polishing is applied to low concentration of salt acid solution;
The 3rd step: the sheet metal through second step is heated to 800 degrees Celsius;
The 4th step: the sheet metal after heating is immersed in hydrochloric acid solution, soak 30 minutes;
The 5th step:: cast iron sheet material is taken out, carry out sanding and polishing for the second time.
Compared with prior art, the beneficial effect that the present invention has is: the present invention in sum, adopts said method to improve the technique of sheet metal flatness, has advantage simple to operate, with low cost.
The specific embodiment
?detailed content of the present invention is illustrated in conjunction with the embodiments.
