Equipment and technology for a core knockout from the casts produced by a method of investment patterns

Read moreThe electrohydropulse technology and the equipment for moulds and cores removal from the casts produced by investment pattern moulding (precision moulding) provide for 100% removal of moulds and cores. Treatment is carried out at two stages; at the first stage the outer coat and approximately 90% of cores are removed, then the parts are cut from a standpipe, and at the second stage additional cleaning is done in a special appliance purposed for the parts with incompletely removed cores. For the purpose to realize this technology, EHP...

Equipment and technology for slag removal from scrap material of metallurgical wastes

Read moreAn operating principle of electrohydropulse plants for waste cleaning against slag is grounded on use of high-voltage discharges in a liquid produced between an electrode and scrap material and accompanied by a complex of physical phenomena, the so-called electrohydraulic effect being an electric explosion in a liquid (almost instant energy generation in the set point), thus resulting in crushing and removal from a surface and from scrap...

Equipment and technology for hardening of roll surfaces, including point switch cores

Away back in the sixties many researchers observed the effect of hardened surfaces in the process of electrohydropulse treatment of the later.

This method is about treatment of surfaces by pressure repeated pulses generated by high-voltage discharges in water. Thus, the treatable structure is also immersed in water. At repeated pulse loading plastic deformation occurs in surface layers of the treatable product. In material structure the increase in density of dislocations is observed, besides in steel structure the twins emerge, and also...
