Organic electrolyte, method for extracting non-metallic inclusions from steel and electrolyzer

Abstract

The invention discloses an organic electrolyte comprising the following components in percentage by weight: 2%-5% of lithium chloride, 5%-8% of gamma-butyrolactone, 2%-5% of ethylene glycol, 0.1%-10% of phenyl surface active agent and balance of absolute ethyl alcohol. The invention also discloses a method for extracting non-metallic inclusions from steel. The method comprises the following steps: preparing the electrolyte, sleeving a microporous cellulose acetate plastic bag on the periphery of a steel sample to electrolyze the steel sample, and separating the inclusions in ultrasonic vibration and vacuum filtration manners. The organic electrolyte is environmentally friendly and low in toxicity. By utilizing the organic electrolyte, body injury to operation staff is obviously reduced, electrolysis time is shortened by accelerating electrolysis through an external magnetic field, the problem that a large number of iron and inclusions of iron and inclusions are difficult to be separated from the anode mud is overcome, and the non-metallic inclusions are accurately and roundly extracted with use of the cellulose acetate plastic bag.

Description

technical field [0001] The invention relates to an electrolyte medium, an electrolysis process and a device, and also relates to a method for extracting non-metallic inclusions in metals, which is applied in the technical field of metallurgical physical chemistry research. Background technique [0002] With the development of science and technology, people have higher and higher requirements for the quality of steel. It is well known that the type, quantity, shape and size distribution of non-metallic inclusions in steel have a very important impact on the quality of steel. Inclusion content is an important indicator for evaluating steel grades. Therefore, it is very important to accurately extract and detect non-metallic inclusions in steel in order to conduct in-depth research on the formation mechanism of inclusions in steel, and timely grasp the types, sources and formation mechanisms of inclusions in steel to further reduce inclusions and produce clean steel guiding s...

Problems solved by technology

However, the currently used non-aqueous solution electrolysis generally has the following deficiencies: First, most of the electrolytes use anhydrous methanol as a solvent, and as we all know, anhydrous methanol is a highly volatile and highly toxic substance that is harmful to the human body. Second, the electrolysis time is too long, the electrolysis speed is slow, the efficiency is low, and the detection cycle is long; third, there are
