Title:
FRICTION MODIFIER, FRICTION MODIFYING APPARATUS AND FRICTION MODIFYING METHOD
Document Type and Number:
Japanese Patent JP2007217539
Kind Code:
A
Abstract:
To provide a friction modifier, a friction modifying apparatus and a friction modifying method which can ease the frictional resistance between a rail and a wheel by using a cheap material and can ease the frictional resistance between the wheel and the rail as much as possible.
The friction modifier C can inexpensively be manufactured by mixing cheap coke particles C1and cheap graphite particles C2in a mixing ratio of within a predetermined range. When the mixing ratio calculating section 13 calculates an optimum mixing ratio of the coke particles C1and the graphite particles C2, the controlling device 14 makes the mixing ratio adjusting sections 5i, 5j adjust the opening of the pipelines 5a, 5b and also makes the mixing ratio adjusting sections 6i, 6j close the pipelines 6a, 6b. When the controlling device 14 makes the gas jetting section 7 operate, the gas jetting section 7 supplies the compressed gas to the pipeline 8. As a result, the coke particles C1in the holding apparatus 5c jet out from the jetting section 5g together with the compressed gas. Similarly, the graphite particles C2in the holding apparatus 5d jet out from the jetting section 5h together with the compressed gas.
