FUCHS LUBRITECH - Speciality Lubricants for The Iron, Steel And Refractory Industry

The high temperatures and pressures as well as the extreme environmental conditions in steelmaking necessitate the use of special lubricants, which are used on high-temperature and pressure-stressed joints and bearings, fastening and motion threads, roller bearings (as minimum quantity lubrication), sliding mechanisms, on the surfaces of ceramic sliding plates, as release assistance for the secondary ceramic components in slide gate systems, gas purge systems and in many other places in the production process.

We offer an extensive product range that comprehensively meets the demands placed and helps steelworks and refractory manufacturers to substantially improve the durability and performance of their products and plants, to decrease downtimes and maintenance work and thus to increase the profitability of their plants. You can rely on our expert knowledge in the fields of development, consulting and support.

Product and application range of the MOLYPAUL ® 900 and 700 series

The MOLYPAUL ® 900 and 700 product series contain lu- bricant variants based on synthetic and natural graphites, which are used as coating and parting lubricants in the production plants of refractory manufacturers and in the “flow control” area of the iron and steel industry.

Main fields of application

• Surface coating of ceramic sliding plates.
• Cold surface coating of sealing surfaces of secondary ceramics.
• Separation of ceramic wearing parts after use.
• Hot-spraying on ceramic surfaces in steelworks.
• Coating of casting moulds for the production of prefabricated ceramic compone.
• Mould release (casting templates), e.g. fireproof ceramic dry-setting mix
• Coating of continuous casting moulds for start-up assistance and wear protection (continuous casting plants for billets and blooms, slabs and thin slabs

Surface coating of ceramic sliding plates

Coating with high-performance lubricants improve the durability of the ceramic sliding plates, increase safety in use in the steelworks and thus contributes reduction in maintenance costs and possible downtime costs. Thanks to their high resistance to oxidation and a low coefficient of friction, the products from the MOLYPAUL® 900 series make a substantial contribution to this.

Surface coating of ceramic linear sliding plate

MOLYPAUL ® 900/50, MOLYPAUL ® 900, MOLYPAUL ® 919, MOLYPAUL ® 942 FAV

• Water-based, paste-like products
• Dense, oxidation-resistant wearing layer is created
• Application with a sponge, brush, spatula or fibre roller

Ceramic plate coating

MOLYPAUL® 912

• Paste-like product
• Low-friction, oil-based emulsion for use on rotary sliding valve ceramic plates
• System-related tolerance differences and surface unevenness are compensated
• Lubricant is applied directly after installation into the slide valve mechanism
• Application with a sponge, brush or fibre cloth

Surface coating of linear sliding plate

MOLYPAUL® 950, MOLYPAUL® 930

• Water-based, sprayable products
• High-performance, abrasion-resistant lubricating film is created
• Surface is low-friction and resistant to oxidation
• Application with a manual spray gun or an automatic or semi-automatic spraying device

Surface coating of secondary ceramic components

The paste-like MOLY-PAUL® products fulfil this task, dry out at room temperature after application and close the open pores in the ceramic surface.

The wettability is lowered and prevents the penetration of the grout into the pore structure of the component. The wearing parts and any remaining grout residues are easy to remove.

Cold coating of the sealing surface

MOLYPAUL® 900

• Product is applied to the sealing surface of the ceramic sliding ladle nozzle
• The high release effect enables the easy and quick exchange of the head plate, which is bonded by a grouted joint
• Adhering grout residues can be removed easily and gently; the sleeve durability is positively affected

Cold coating of the well block mounting cone

MOLYPAUL® 900

• Wettability of the ceramic surface is reduced
• After use the components (sliding nozzles, porous plug) can be removed quickly and cleanly
• Adhering mortar release can be removed easily; the nozzle brick durability is positively affected

Hot-spraying on ceramic surfaces

After spraying, the product developed especially for this application, MOLYPAUL® 994, creates a dense, closed, dry lubrication film with a graphite structure tailored to the application. This decisively reduces the wettability of the ceramic component with respect to the grout/putty used. The efficient exchange of wearing parts is thus ensured.

Particular importance is attached to fine atomisation when spraying. The liquid content of the lubricant serves as a carrier material, which ensures the optimum distribution of the parting substances on the hot ceramic surfaces by spraying. The “Easy Spray Gun” manual spray gun is ideal for the application. No smoke or odours are generated during the application.

MOLYPAUL® 994

• Water-based solid lubricant, especially for spray application to hot surfaces
• Release function of the ceramic components, which are connected via mortar joints
• Application with a low-maintenance, pneumatically operated manual spray gun (Easy Spray Gun)
• Closed, low-friction lubricating film with high release effect is created

Spraying areas:

• Plate surfaces
• Ladle nozzle / exchangeable nozzle sealing surface
• Ladle nozzle brick holding cone /sliding sleeve and porous plug
• Tundish bottom nozzle / submerged entry nozzle

Coating of continuous casting moulds

The MOLYPAUL® products are easy to apply without drips. A self-contained lubricating film with excellent sliding properties is formed. The lubricant application enables the time-delayed use of the standard oil lubrication during the initial casting phase. The danger of deflagrations is minimised.

Continuous casting plant for billets and blooms

MOLYPAUL® 783

• Paste-like, non-dripping lubricant on a graphite basis
• Easy to apply
• A compact lubricating film with a low coefficient of friction is created under the influence of temperature
• Shell formations on the mould walls are effectively prevented
• Replaces the standard oil lubrication during initial casting; the danger of deflagrations is minimised
• Applied using fibre cushions or a fleece roller

Continuous casting plants for slabs and thin slabs

MOLYPAUL® 783

• Sprayable, ready to use and aqueous suspension
• Forms a resistant dry lubricating film on ambient-temperature with a high release effect
• Low coefficient of friction and high abrasion resistance ensure a smooth start-up of the dummy bar and protect the metal moulds against scoring and wear during insertion
• Service life of the mould is prolonged
• Applied using spraying apparatus, a fibre roller or a fibre pad

Release of fireproof ceramic products, casting templates and moulds

The MOLYPAUL® products can be applied without drips and enable clean demoulding. The moulded article remains free of unwanted discolourations and the mould is ready for the next use without the necessity for extensive cleaning. Multiple use of the casting mould is possible, since a new coating often doesn’t have to be applied before each use.

• Cream-coloured liquid emulsion
• Non-hardening, non-dripping release layer forms
• No discolourations are formed on the ceramic moulded articles
