The core application areas for water–ethylene glycol fire-resistant hydraulic fluids are industrial sectors where there is a high risk of fire—such as exposure to high temperatures, open flames, or molten metals—and where the safety of hydraulic systems is of paramount importance. In the following industries, these fluids are widely used as critical fire-safe hydraulic media:
1. Metallurgical Industry
This is one of the primary application areas for water–glycol hydraulic fluids, covering the entire process from ironmaking and steelmaking to rolling, and effectively preventing fires caused by hydraulic fluid leaks. Specific applications include:
High-temperature furnace and kiln area: hydraulic systems for equipment such as converters, electric furnaces, coke ovens, and smelting furnaces.
Casting, forging, and hot-rolling equipment: such as continuous casting machines, tandem rolling mills, plate coilers for hot continuous rolling mills, high-speed wire drawing machines, and metal die-casting machines, among others.
Other high-temperature equipment: such as glass forming machines, cement kilns, and coal gasifiers, among others.
2. Coal Mining Industry
In underground coal mines, particularly in environments where flammable and explosive gases such as methane are present, the use of water–ethylene glycol fire-resistant hydraulic fluid can significantly reduce the risk of fire and explosion. The main equipment includes:
Mining equipment: coal mining machines, roadheaders, and continuous miners.
Support equipment: hydraulic supports.
Auxiliary equipment: hydraulic tensioning devices, etc.
5. Shipbuilding and Ocean Engineering
Ship engine rooms are enclosed spaces with high personnel density and the presence of high-temperature equipment; the use of water–ethylene glycol hydraulic fluid can reduce the risk of fire. Specific applications include:
Marine equipment: hydraulic systems for steering gear, cargo cranes, and other machinery.
Special applications: offshore oil drilling platforms, shipboard hydraulic systems, and the like.
6. Chemical Industry
In chemical manufacturing, the use of water–ethylene glycol fire-resistant hydraulic fluid in high-temperature reactors, high-pressure reactors, and other equipment can help prevent accidents caused by leaks.
7. Power Industry
It is primarily used in thermal power plants, where it is applied to the hydraulic systems of equipment such as steam turbines and coal mills to prevent oil leaks from coming into contact with high-temperature components and causing fires.
8. Other Important Application Areas
Aerospace: Used in highly safety-critical applications such as landing gear and flight control systems.
National Defense and Military Industry: Used in military equipment and aiming devices, among others.
Light industry and plastic processing: These materials are also used in fire-resistant hydraulic systems for plastic processing, light industry, and other applications.
