Abstract

The invention belongs to the technical field of electrochemical processing of metal materials, and discloses a test method for the electrolyte used in the electrolytic grinding of high-speed steel roll materials. The electrolyte obtained by using the method is calculated by mass percentage: sodium sulfate 2%~8%, phosphoric acid Sodium dihydrogen is 20%, and the balance is deionized water; the method also uses an electrolyte liquid supply system for electrolytic grinding of high-speed steel roll materials, which includes processing power supply, grinding wheel, cathode tool, water tank, motor, Hydraulic pumps, electrolytic reaction tanks, filters, tee pipes, solenoid valves, safety valves, pressure reducing valves, pressure gauges, throttle valves, electromagnetic flowmeters, modification devices and chillers. The water tank is connected with liquid level switches, filter screen, PH detector, heater, temperature sensor, liquid level gauge, liquid unloading valve and water tank cover; the present invention solves the problem of low processing efficiency, high processing cost and surface quality of the prior art mechanical grinding processing and repairing high-speed steel rolls Poor problem, used for electrolytic grinding of high-speed steel roll material.

Description

technical field [0001] The invention relates to the technical field of electrochemical processing of metal materials, in particular to a test method for electrolyte used in electrolytic grinding of high-speed steel roll materials. Background technique [0002] The roll is the core component of the rolling mill, and its material and material properties directly affect the production quality of the steel plate. Due to the advantages of high-speed steel rolls such as good wear resistance, thermal shock resistance, hardenability and high friction coefficient, rolls made of high-speed steel rolls are mostly used as work rolls for hot rolling mills in the market. However, during the working process of the roll, if the cooling system fails to cool it in time, and the carbide itself is not uniformly dispersed, the roll is subjected to the rolling force and the matrix around it will be worn to varying degrees; in addition, the material of the high-speed steel roll The linear expansi...
