DIGITAL DENSITY MIXING LEVEL TEST KIT
for HOT ROLLING OIL SYSTEM

The merits and working instruction for TOYO-SUN D･D KIT

1)

Table�Tshows the example of the ideal transparency numbers obtained through TOYO-SUN photo sensor at each nozzle horizontally, (No.1〜No.6) and at each density from 0.1 to 1.0 percent vertically. By finding out the numbers as shows in the table�Tin their spray headers at hot rolling oil system. They can fulfill the most efficient plate-out evenly with minimum oil consumption. The each number indicates the volume of plate-out indirectly. If unevenness of number horizontally, the uneven spray is done in density or mixing grade.

Table�T　Density Mixing grade and transparency number after spraying



Table�U　Mixing & plate-out at 5 percent density

2)	Table�Ushows the velocity and transparency number related to the　plate-out at density of 0.5 percent. You can find out the weight of plate-out proportioned to the velocity inside mixer with even the same density. It is possible for customers to save the oil cost by 40 percent less.

3)

Fig�Tshows a graph converted to the table�U. In case of the density lesser than 5 percent there is a possibility of uneven spray in density at each nozzle, resulting uneven lubrication at rolling action. Plate-out greatly depends upon not only velocity but also oil viscosity, water temp. and other parameters. We recommend that customers are in need of grasping the most efficient transparency number through our laboratory test.

Fig �U

Fig�Ushows water temp. horizontally and plate-out vertically. Water temp. greatly affects the plate-out even if the same density. For example, in case of 1.5 percent in density, the plate-out of 0.042g in weight at 25℃ of water temp. is extremely changed to that of 0.125g in weight at 10℃ of water temp., that is to say, this is three times the weight of plate-out at 25℃ of water temp. however you should consider what evenly the nozzle sprays. And about nozzle clogging. The HV mixer will deal with those troublesome parameters flexibly.
