PROCESS
The centrifugal casting process is used to produce pipe, while static casting is used to produce fittings, manhole covers and others castings. Centrifugal casting and modern static casting provide rigid production control and yields high quality pipe, fittings and manhole covers of uniform dimensions cast to exacting specifications.
Centrifugal Casting in horizontal moulds is used to make long, concentric, hollow castings. In the centrifugal pipe casting process, a water-cooled metal mould is rotated on a horizontal axis during the interval of time that it receives a pre-measured quantity of molten iron. The centrifugal force created by this rotation causes the liquid iron to spread uniformly onto the mould’s inner surface, thereby forming upon solidification a cylindrical pipe conforming to the inside dimensions of the mould. After the pipe is cast, it is allowed to solidify in the still rotating mould. Finally, the pipe is removed from the mould and is conveyed to the foundry’s cleaning and finishing department.
Static Sand Casting uses sand cores surrounded by green-sand moulds into which molten iron is poured to form castings. The sand is termed “green” because of its moisture content rather than its colour. The sand-casting process involves pattern making, moulding, core making and pouring after which the product is conveyed to the foundry’s cleaning and finishing department.
Cleaning and Finishing Operations include the following steps and procedures:
Brushing and Fettling: After the newly cast pipe, fittings and manhole covers have been removed from their moulds and allowed to cool, they must be properly cleaned to remove moulding sand, core sand, gates, fins, and risers.
Technical Inspection: After the castings have been cleaned, they are inspected and tested for strict conformance to all standards and specifications under the Bureau of Indian Standard. In the laboratory, test samples undergo more exacting physical testing and chemical analysis.
Coating: After inspection and testing, pipe, fittings and manhole covers are coated as per the customer requirements. The finished pipe, fittings and manhole covers are then moved into storage or prepared for shipment.
