Capital produces and supplies a wide range of pressed and cast specialist shapes and can cast, dry and fire castable shapes to tight tolerances. We are constantly reacting to customer demand and developing new ranges. Please contact us with your requirements.
Our ranges include crucibles, ladles and T-pot ladles, distribution boxes/head boxes, launders, tundishes, nozzles (cast SRO), well blocks, installation blocks, burner tiles and dosing cones.
Crucibles are produced by vibration casting (vibrocast) when the required size or shape is uneconomical or impractical by the isopressing production method. We can produce vibrocast crucibles with capacities of up to 2.7 tonne (equivalent steel).
We are able to produce precast and fired t-pot ladles. We produce several models, see table below. Please contact us for more information.
These special shapes are designed to bespoke customer needs, usually used in superalloy manufacturing. Various shapes and sizes enable equal distribution of metal to the mould. Qualities include high thermal shock resistance, high mechanical strength for vacuum induction melting.
High alumina and sillimanite formulations allow Capital to design reliable solutions for each application.
Launders and tundishes are typically used in many metal liquid processing industries including steel, superalloy, and aluminium. They can be designed to customer specifications and equipped with filters, dams or bars used to help clean the metal.
Properties include high thermal shock resistance, high mechanical strength, used in vacuum induction melting. High alumina, and sillimanite formulations allow Capital to design reliable solutions for each application.
These are for the installation of gas diffusers or nozzles. They can be made by Capital to any size or shape to suit operating conditions and can be pre-fired if necessary, to ensure optimum performance. Quick and easy to install.
Bespoke shapes and designs can be made to suit customer requirements using high-quality heat resistant material enabling maximum efficiency and a longer working life.
Quality in-house laboratory testing is also available for any physical property analysis.
