FOUNDRIES NIGERIAN

LIMITED RC: 6297

Nigerian Foundries Ltd is the oldest (since 1969) private sector foun-dry group in West Africa with a total melting capacity of 8,500 tons of ferrous metal. It has two plants, one at Ilupeju and one at Otta, Ogun state. NFL amongst others specializes in replacement castings used in equipment applied to cement manufacture, namely: Crushers (jaw, cone, mineral sizer, roll, and gyratory) Hammermills and horizontal shaft ipactors Pulverizers and roller mills Ball mills Prehaeters, kilns and coolers Material handling equipment (drag chain conveyors, apron feed-ers, etc) STATE-OF-THE-ART QUALITY CONTROL NFL posses a quality system that is able to guarantee the quality of castings as castings are produced and supplied in batches. Each casting carries a batch number, and for every batch a quality certification is issued attesting to their conformance to the agreed specification stan-dard with client. Full fledged metallurgical and metallographic laboratories coupled with comprehensive quality testing procedures, endure that all standards are met as per customer orders. With our Computer Aided Design software and our advanced computer casting simulation programme called Mavis, we are able to produce pat-tern faster by getting high integrity castings “right, the first time” and cheaper by avoiding costly development delays. Full fledged machine shop facilities allow for precision machining of parts and components tailored to the customer's requests and needs. NFL operates the latest in electronically controlled oil fired, heat treatment facilities complete with graphed recording facilities to monitor heat cy-cles. Water quenching, oil quenching and air quenching facilities are also employed to ensure that optimum mechanical properties and grain structures are achieved so as to satisfy the exact specifications of our ever expanding customer base.

CEMENT CASTINGS We cast to last since 1969...

About us

Foundry Cast-ings

A variety of alloys are available for wear and heat-resistant castings. The two most important properties for wear-resistant castings are hardness and toughness. For heat-resistant castings, significant properties include high-temperature creep strength, resistance to hot gas corrosion, and abrasion resistance. Selecting the right alloy for a part requires balancing material properties based on clear communication and close cooperation between the customer and a knowledgeable supplier. Choosing the optimum casting material can lower the cost per ton of material produced.

TOUGH NFL ALLOYS TO FIT MOST APPLICATIONS

Hardness (HB)

The ability to resist indentation, an indication of resistance to abrasion. Common methods for measuring hardness include the Brinell, Rockwell and Vickers hardness test. There is a direct relationship between hardness and the tensil strength of steels.

Toughness The ability to withstand shock loading without fracture or distortion – the opposite of brittleness. The most common testing method for steels is the Charpy Impact Test.

Machineability

The ability to be machined. Machineability is inversely related to hardness. The higher the hardness, the less machineable a material. Drilling and tapping operations are normally limited to materials with hardness of 400 HB or less. Mn steels and heat-resistant steels work-harden under load and are less machineable than their hardness would indicate.

Ductility The ability to be mechanically deformed without fracture. Ductility is inversely related to hardness. The higher the hardness, the less formable a material will be. Straightening of castings is normally limited to materials with hardness of 400 HB or less.

Weldability The ability to absorb thermal shock without exhibiting detrimental effects. Materials with low weldability require weld preheat and weld post heat. Some materials are considered not weldable because of the high risk of cracking.

Poor - Good

High temperature/corrosive resistant parts for cement and lime, ore refining, steel, oil refining, chemical and furnace applications.

Carbon Steels

Ductility, weldability and heat treated tensile strength levels up to 100KSA. Most common grades available.
