Title:
SAWTOOTH LOAD REDUCTION METHOD BY SPRAYING LUBRICATING OIL
Document Type and Number:
Japanese Patent JP2000210813
Kind Code:
A
Abstract:

To remove a fault that the load on a sawtooth is great in cutting a steel piece of hot steel by a hot saw. In particular, to reduce the load on a sawtooth, improve the life simultaneously and reduce power consumption at steel piece cutting by improving lubrication between the steel piece and the sawtooth at steel piece cutting.

This is a method to reduce the load on a sawtooth 7 attached on a hot saw cutting a steel piece spraying a lubricating oil mixed with industrial water on the tip and the sides of the sawtooth 7 in cutting of the steel piece for hot steel material. At this time, the lubricating oil from an oil reservoir 6 is pumped up by a pump 5 to a mixer 3 and mixed with industrial water at the mixer 3. The density of the lubricating oil to be mixed with industrial water is 0.1-5% and the pressure of the mixed liquid of industrial water and lubricating oil to be sprayed on the sawtooth 7 is in the range of 0.1-10 kg/cm2.
