Abstract
The invention discloses a kind of scrap steel processing methods comprising following procedure：Scrap steel is dipped in aqueous slkali, and it is connected with positive pole, it is electrochemically reacted, it after falling off to scrap steel overlay coating, is drawn off, is rinsed using surfactant solution, thereafter it is rinsed and is dried with deionized water, its backward scrap steel surface covers LDPE films, is vacuumized after covering, until LDPE films are fitted closely in steel surface.Resource recovery can be improved in the present invention, reduces environmental pollution.
Description
Technical field
The present invention relates to the technical fields of scrap steel processing.
Background technology
Scrap iron and steel is a kind of important recyclable resources, essentially from iron and steel enterprise's production waste, industry and life
The steel scrap etc. of middle recycling.
In the prior art to scrap iron and steel by mainly in such a way that electric furnace steel making is re-refined, the existing skill in part
It is also recycled as the cold burden in pneumatic steelmaking in art.The cigarette of high zinc content can be all generated in both modes
Dirt influences environment, and can result in waste of resources if direct emission, if flue dust is recycled, but process is complicated, at
This is high, and yield is extremely low.
Invention content
It is an object of the invention to propose a kind of scrap steel processing method, by first carrying out processing removal coating to scrap steel
Mode, improve resource recovery, reduce environmental pollution.
Technical scheme is as follows：
A kind of scrap steel processing method comprising following procedure：Scrap steel is dipped in aqueous slkali, and by itself and positive pole phase
Even, it is electrochemically reacted, until after scrap steel overlay coating falls off, is drawn off, is rinsed and dried using surfactant solution
It is dry, it is rinsed with deionized water thereafter, the backward scrap steel surface covers LDPE films, is vacuumized after covering, until LDPE films are close
Fit in steel surface.
Preferably：The surfactant solution includes following components：Neopelex and fatty alcohol polyoxy
Vinethene.
It is also preferred that：The aqueous slkali is sodium hydrate aqueous solution.
Further preferably：A concentration of 20 ~ 30wt% of the sodium hydroxide solution.
The present invention can first be handled scrap steel, to remove and recycle the coating on its surface, and can be effectively isolated nothing
Coating scrap steel and air etc. contact, and prevent it and are aoxidized, corroded, can when thus obtained scrap steel is subsequently refined again
Steel-making energy consumption is greatly reduced, steel-making efficiency is improved, reduces environmental pollution.
Specific implementation mode
Scrap steel processing is carried out in the following manner：
Scrap steel is dipped in aqueous slkali, and it is connected with positive pole, is electrochemically reacted, until scrap steel overlay coating
It after falling off, is drawn off, is rinsed and dried using surfactant solution, rinsed with deionized water thereafter, the backward steel scrap
Material surface covers LDPE films, is vacuumized after covering, until LDPE films are fitted closely in steel surface.
Preferably：The surfactant solution includes following components：Neopelex and fatty alcohol polyoxy
Vinethene.
It is also preferred that：The aqueous slkali is sodium hydrate aqueous solution.
Further preferably：A concentration of 20 ~ 30wt% of the sodium hydroxide solution.
