Baskets Heat Treatment Fixtures 2.4879 Heat - Resistant Steel Tray

Product Specification

EB Castings supplies drawing-based enquiries for 2.4879 heat treatment baskets and trays used to support industrial workpieces through furnace operations. Cast grid sections, ribs and locating features form a fixture that fits the equipment and keeps the load arranged for processing. The useful specification combines alloy designation with the basket geometry, workpiece layout and thermal cycle, rather than treating every furnace fixture as interchangeable.

A basket designed around the load

The basket or tray carries parts through heating and subsequent handling. The outside envelope determines its clearance in the equipment, while the grid and internal supports establish where the workpieces sit. Openings provide access around the load without replacing the structural function of the supporting ribs.

A replacement drawing should identify the contact locations between the workpieces, the fixture and the furnace support. Concentrated loads and stacked assemblies require a different review from a uniformly distributed load. Include the intended mass and support arrangement so the casting can be assessed as a complete working fixture.

2.4879 alloy and furnace duty

The specified grade is 2.4879, a heat-resistant cast alloy. Alloy selection and permissible operating conditions need to be considered alongside load, atmosphere and exposure time. A temperature figure alone does not establish the allowable duty of a basket with a particular span or support arrangement.

Record the normal heating range, holding time and cooling sequence. Furnace atmosphere and chemical exposure are also relevant to the fixture review. For repeat orders, retain the approved material specification and delivery condition together with the drawing revision, rather than changing the grade to a generic stainless steel description.

Cast structure and finished interfaces

The manufacturing plan starts with the component geometry. Grid thickness, corner transitions and the position of locating features are shown on the drawing. Casting and any finishing operations are then selected for the particular component; not every casting process is suitable for every basket shape.

Specify where machined contact faces, mounting holes or locating dimensions are required. Separate these functional interfaces from general cast surfaces. This gives the quotation a clear boundary between the cast component and its finished condition without assuming that every surface requires machining.

Handling and replacement compatibility

The fixture must suit loading, transfer and seating in the existing equipment. Identify the lifting or handling interfaces provided by the approved design, along with any mating tray or frame. Where baskets are stacked, the connection between levels belongs in the assembly information.

A used basket may be distorted or locally worn. Photographs help explain the service history, but the replacement dimensions should follow a controlled drawing. Comparing the original support positions with the current loading arrangement is useful when workpiece sizes or furnace operations have changed.

Inspection and purchasing information

Dimensional acceptance can focus on the overall envelope, support levels, locating positions and finished interfaces. The order identifies the material records and any additional examination required. Measured results apply to the supplied batch and should not be inferred from a reference photograph.

For a quotation, provide the drawing, required quantity, furnace cycle and loading arrangement. EB Castings can discuss the casting and finishing scope against these requirements. A well-defined fixture enquiry supports consistent replacement purchasing and clearer communication between maintenance, process engineering and procurement.
