Pre-Cut Master Alloy Segments for Investment Casting

Pre-cut master alloy charging segments are supplied to investment casting shops in the length the furnace takes, cut from cast bar in diameters of 8.0 mm to 200 mm, so the material reaches the melt shop ready to weigh and charge.

Why Segments Suit a Melting Shop

A melting shop measures its charge, not its bar. What goes into the crucible is a weight of metal, and it arrives as pieces the furnace can accept. When those pieces come that way from the supplier, the receiving bay does the weighing and nothing else. When they arrive as full bars, the bay has to cut first, and a cutting step in a foundry is a step with a saw, a man and a queue.

That is the whole case for ordering segments. The metal is the same metal, the certificate is the same certificate, and the difference sits in the last metre between the case and the crucible.

Specifications

Key Strengths

• Cut to the charge length in use at the foundry.
• Diameters from 8.0 mm to 200 mm.
• Segment mass stated before the order is placed.
• Lot certificate issued with the consignment.
• Cases marked so a delivery can be checked at the gate.

Technical Details

What a Segment Order Specifies

Three items define a segment order. The diameter fixes the section that goes into the crucible. The length fixes how the piece sits in the charge bucket and how many pieces make up one charge. The grade agreement fixes the composition, as it does for any cast lot. Give those three and the cut is placed with the cast rather than after it.

How the Cutting Length Is Fixed

The length comes from the foundry, not from a catalogue. A shop charging a small crucible may take pieces cut to a hand length, while a larger furnace may accept a longer segment that one man can still lift. The length in use is written on the order, and the bar is cut to it at the works, which keeps the piece count per charge predictable on the foundry floor.

Weighing a Charge in the Bay

Segments change the routine in the receiving bay. The pieces are counted and weighed against the charge sheet, and the arithmetic is visible on the scale rather than inferred from a bar. Where a shop records the material entering each heat, a segment order makes that record straightforward to keep, and the certificate held with the lot can be matched to the charge without converting a bar length into a weight first.

Packing Segments for the Sea Leg

Segments are bundled, wrapped against moisture and packed into export wooden cases. Each case carries the grade, the diameter, the segment length and the lot number, and the case numbers repeat on the packing list. Because the pieces are already cut, the cases settle into a tighter load than full bars, and the mass per case is stated on the packing list so the receiving bay knows what it is lifting.

Segments in the Investment Casting Melt

Investment casting shops buy these segments as the addition to their own heat, and the castings that follow reach aero engine work, turbocharger wheels for automotive use, pump bodies and valves for chemical service, and hardware for glass production.

Quality Assurance

The composition of each cast is checked against the grade agreed on the order, and the surface is inspected before packing. Cutting does not change the material that was released, so the certificate issued with a segment order describes the same lot that the bar was cast from, and the consignee can match it against the cases at the gate.

References

The grade series behind these segments is the cast grade series for high-temperature alloys used in the Chinese standard system, and the cut is made from bar cast to the composition agreed on the order. Chemistry and structure are read against the inspection record kept for the lot and the certificate released with the consignment.

Packaging & Delivery

Segments are bundled, wrapped against moisture and packed in export wooden cases marked with the grade, the diameter, the segment length and the lot number. A production lot is scheduled over 15-30 days from order confirmation. Freight terms are quoted against the port named on the enquiry, whether on FOB, CFR or CIF.

About DLX Alloy

Volume at Changzhou DLX Alloy Co., Ltd. runs to 10,000 tons a year from a 12,000 m² works in Changzhou, where alloys have been melted and processed since 2002 and where ISO 9001 and SGS certification are held. Customers in more than 60 export countries buy from that supply. A segment order is handled as a cut of the same cast bar supplied across the range, with the length taken from the foundry's own charging practice.

FAQ

Q: What is a charging segment?
A: A piece of cast master alloy bar cut to the length the furnace accepts, so the melting shop weighs the charge and puts it in without cutting anything on site.

Q: How is the segment length decided?
A: By the foundry, from its own charging practice. The length in use is stated on the order, and the bar is cut to it at the works.

Q: Is the segment mass given in advance?
A: Yes. Segment mass is stated per diameter and length, so the receiving bay knows the load per piece and the total per case.

Q: How are segments packed?
A: Bundled and wrapped against moisture, then packed in export wooden cases carrying the grade, the diameter, the segment length and the lot number.

Q: Does cutting change the material?
A: No. Segments are cut from bar cast to the grade agreed on the order, and the certificate issued with the consignment covers that same lot.

Q: What is the minimum order quantity?
A: It follows from the diameter and the quantity of metal the shop needs per charge or per campaign.

Q: What is the delivery time?
A: A production lot goes on the schedule 15-30 days after order confirmation.

Q: Which shipping terms are quoted?
A: FOB, CFR or CIF to the destination port named on the enquiry, quoted with the order.
