specific Embodiment approach

[0047] Put the configured electrolyte 1 in the water tank, and then start the power supply of the motor 5 of the electrolyte 1 liquid supply system to start working. During the work, use the pressure gauge 11 and the electromagnetic flowmeter 13 to read the electrolyte 1 in the system. According to the pressure and flow of electrolyte 1 in the system loop, adjust the hydraulic pump 6, pressure reducing valve 9, and safety valve 21 to ensure that the pressure and flow of electrolyte 1 in the system loop are appropriate, and use thermometer 22 to read The temperature of the electrolyte 1, and control the chiller 28 or the heater 36 to work according to the temperature value to ensure that the electrolyte 1 is at a suitable temperature. Use the pH detector 23 to read the pH value of the electrolyte 1, and adjust the additives in the modification device 30 according to the pH value of the electrolyte 1 to ensure that the pH value of the electrolyte 1 is between 7 and 9, and use the...

Abstract

The invention belongs to the technical field of electrochemical machining of metal materials, and discloses a high-speed steel roller material electrolytic grinding electrolyte which comprises sodium dihydrogen phosphate, sodium sulfate and deionized water. An electrolyte supply system for electrolytic grinding of high-speed steel roller materials comprises a machining power source, a grinding wheel, a cathode tool, a water containing tank, a motor, a hydraulic pump, an electrolytic reaction tank, a filter, a three-way pipe, a two-position two-way normally-open electromagnetic valve, a safety valve, a pressure reducing valve, a pressure gauge, a throttling valve, an electromagnetic flowmeter, a gate valve, a one-way valve, a modification device and a cooling-water machine, and the water tank is filled with electrolyte and is connected with a liquid level switch, a coarse filter screen, a PH detector, a heater, a fine filter screen, a temperature sensor, a liquid level meter, a liquid discharge valve and a water tank sealing cover. The problems of low machining efficiency, high machining cost and poor surface quality of mechanical grinding machining and repairing of a high-speed steel roller in the prior art are solved, and the electrolyte and the electrolyte supply system are suitable for electrolytic grinding of high-speed steel roller materials.

Description

technical field [0001] The invention relates to the technical field of electrochemical processing of metal materials, in particular to an electrolyte for electrolytic grinding of high-speed steel roll materials and an electrolyte supply system. 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 ...
