Iron and sintering equipment such as coke machine, coke pushing machine, limestone and ore sintering equipment, large blowers, ore bucket traction rope and other top equipment, cupola, blast furnace, conveyor belt, etc., most exposed to the air and dust, corrosive dust environment, vulnerable to corrosion, abrasive wear and cavitation. To which the corresponding bearing, gear, gears, worm gear, hydraulic systems, wire rope, etc. should be lubricated.

Machinery due to frequent exposure to coking coal powder filled the air, and therefore must be sealed lubrication, such as door switch and turn the end quench cars and other vehicles and washout of the hydraulic system, generally use water - glycol fire-resistant hydraulic fluid ; belt conveyor shaft use lithium or calcium complex grease lubrication.

Pushing machine indirect jobs, and is the shock loads in coal dust and high temperature environment, the need to use heat, water and good extreme pressure lithium grease or oxidation, rust and extreme pressure lubricating oil circulating lubrication, hydraulic systems To use fire-resistant hydraulic fluid.

Gas purification and chemical by-product recovery partly mechanical, due to dust and corrosive fumes, thus sending machines such as gas discharge lubricant should contain antioxidant antirust turbine oil, and apply with filter lubrication system.

Limestone and ore sintering equipment, often working in dust and vibration and high temperatures, and thus to the use of composite calcium-based, lithium complex, aluminum complex grease or bentonite.

Large-scale blast furnace, ore bucket hoisting rope and other top equipment generally can be 0 or the 1st extreme pressure lithium grease, dry oil lubrication system for lubrication, phosphate flame retardant roof machinery available for the hydraulic fluid medium. Hot metal chartered large load, high temperature, required dropping point greater than 125 ℃ extreme pressure lithium-based grease.

2. Lubricate steelmaking equipment

Modern steelmaking furnace operation using computer control, high degree of automation, the equipment used require a corresponding lubrication systems and lubricants.
