How hot is too hot? Hydraulic fluid temperatures above 180°F (82°C) damage most seal compounds and accelerate degradation of the oil. While the operation of any hydraulic system at temperatures above 180°F should be avoided, fluid temperature is too high when viscosity falls below the optimum value for the hydraulic system''s components.

Dec 04, 2005· Read the book and be sure you understand the hydraulic sequence before you start screwing around with the system. Most of the closed loop systems on skid steers will not even push out air bubbles. The system is balanced and only uses the resivor tank when there is a fluid leak, or temperature change. I think your New Holland is this type of system.
M oisture is omnipresent in steel mills. It comes primarily from mill cooling water entering the circulating oil system and from simple condensation during mill downtime. Although necessary to reduce the extreme heat generated in the processing of steel, water is among the most destructive contaminants to the circulating oil system.

Slabs are the feed material for hot strip mills or plate mills and blooms are rolled to billets in a billet mill or large sections in a structural mill. The output from a strip mill is coiled and, subsequently, used as the feed for a cold rolling mill or used directly by fabricators.
HOT STRIP MILL — HIGHEST PERFORMANCE FOR NEW AND EXISTING STEEL MILLS The demand for hot rolled strip is growing in multiple ways. To remain competitive, new and existing mills must meet this challenge in the best possible way. The production of hot strip is a .
The Pickling Process CSI''s pickling line started up in late 1994, and typically processes two out of every three coils produced at the Hot Mill. Its primary function is to remove the thin layer of oxidized iron, or scale, that forms on the surface of the steel at the temperatures employed during hot rolling.
The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semifinished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.
