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 ...
