Description
Technical field
The present invention relates to derusting technical fields, and in particular to a kind of processing of rust removing technique of spring steel.
Background technique
Present China is due to manufacturing fast development, so that steel product excess capacity usually occurs during production
The case where, according to incompletely statistics, lead to the discarded loss of getting rusty of steel due to annual steel excess capacity in China, occupies every
1/4 or so of year steel production, causes serious wasting phenomenon.
Spring steel refer to due to quench and annealed strip under elasticity, and dedicated for manufacture spring and elastic element
Steel, spring use under shock and vibration or long-term friendship stress, it requires that spring steel has high tensile strength, elastic limit, height
Fatigue strength, spring steel more demanding intensity and fatigue limit.But spring steel will lead to during long-term storage
Surface oxidisation, commonly in traditional derusting method, hand cleaning speed is slow, and brain hole intensity is big, and the low efficiency to derust, and chemical
So that the surface mass of spring steel construction easily changes, the serious toughness that also will affect spring steel and structure are strong for processing
Degree, and the influence to environment, same high-intensitive mechanical derusting technique are bigger to the surface of spring steel construction.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of processing of rust removing technique of spring steel, so that spring steel
Surface derusting better effect, and it is not right.
In order to achieve the above object, the present invention is achieved by the following technical programs:
A kind of processing of rust removing technique of spring steel, operating procedure are as follows:
1) it will need to be infiltrated on the spring steel to derust with glycerol；
2) surface grinding process, revolving speed 200-300r/min are carried out with electronic water sand wheel；
3) by step 2), treated that spring steel is placed in rust removing solution infiltrates 5-10min；
4) spot of spring steel surface is cleaned with cooling boiling water；
5) by the spring steel infiltration after cleaning in also 4-6% potassium chloride and sodium carbonate mixed aqueous solutions；
6) step 5) spring steel is being cleaned with the hydraulic pressure of 7-9MPa again；
7) spring steel after cleaning is prevented from being dried in vacuo in drying box, drying temperature is 50-70 DEG C.
Preferably, controlled at 50-60 DEG C in the step 3).
Preferably, the group of rust removing solution is divided into dilute sulfuric acid 20-30%, ammonium citrate 20-30%, carbonic acid in the step 3)
Sodium 25-30%, triethanolamine 10-20%.
Preferably, the time of the step 5) infiltration is 10-15min.
Preferably, the drying time of the step 7) is 2-3h.
The present invention provides a kind of processing of rust removing techniques of spring steel, by first carrying out mechanical grinding in operating procedure
The rusty stain of removal spring steel surface, convenient for being contacted with rust removing solution, can carry out deep layer so that the surface of spring steel is more coarse
The rusty stain of secondary removal spring steel, and cooling boiling water can remove the composition of air in water removal, avoid composition of air in water with
Spring steel is further formed rusty stain, and rust removing solution used, can be with bullet in 4-6% potassium chloride and sodium carbonate mixed aqueous solutions
Spring steel forms fine and close protective layer, avoids further contacting with air.Entire technological operation is simple, can further genralrlization application.
