Tap hole cone
Vacuum-formed refractory shapes / tap hole cones
We serve several parts used in the casting process of aluminum rods and aluminum alloys.
- PRODUCT VARIATIONS
- Manufacture according to customer specifications
-
Tap hole cone
- Tap hole cones act as a plug to regulate the flow of molten metal from furnaces and ladles, in the casting process of aluminum rods and aluminum alloys.
- They have proper hardness and toughness, not fragile or peel off.
- Cup caps are produced in large quantities by the vacuum suction filter molding process, mixed with specially selected inorganic and organic binders.
Features
- Excellent insulating properties
- High feed efficiency
- High strength/weight ratio
- Good thermal shock resistance
- Low thermal conductivity and thermal mass
- Low heat
- Low smoke
- Non-stick aluminum
- Formulations range from hard molds to very flexible molds with good recovery properties and can be based on ceramic fibers, biosoluble fibers, or mineral fibers. This process is mainly used for round or conical molds.
- They are produced in different densities, specifications, patterns, and performance to meet the most demanding thermal requirements of our customers.
Great Selection of products

Qualities
Various designs and qualities available.
Experienced consulting
Thanks to our years of experience we can advice you for best quality products
An opening at the bottom of the cupola at the cupola heart through which the molten iron can flow out of the furnace via a channel. The tap hole is plugged with a plug after each charge during periodic melting and is pierced again during the next tapping.
Advantages
It has the advantages of lightweight, high-temperature resistance, good thermal stability, low thermal conductivity, small specific heat, and mechanical vibration resistance.

K. Hoffmann GmbH
For over 40 years, we have been manufacturing high-temperature-resistant boards, pressed, and milled molded parts from Vermiculite.
Due to its special properties, vermiculite is particularly suitable as a lightweight insulation material and is characterized by its temperature resistance up to 1100 °C.
If you are also looking for a sustainable insulation material without health concerns, then contact us.
