技术定义与适配语境
典型 浇注嘴 会按材料、尺寸公差、适配关系和失效风险在 基础金属制造 中评估。

A specialized refractory-lined nozzle or spout attached to a crucible, designed to regulate the flow of molten metal during pouring operations in foundry and metal casting applications. It ensures precise directional control, minimizes turbulence, reduces oxidation, and prevents slag inclusion by creating a smooth, consistent stream from the crucible to the mold or ladle.

定义
A specialized refractory-lined nozzle or spout attached to a crucible, designed to regulate the flow of molten metal during pouring operations in foundry and metal casting applications. It ensures precise directional control, minimizes turbulence, reduces oxidation, and prevents slag inclusion by creating a smooth, consistent stream from the crucible to the mold or ladle.
工作原理
Operates by gravity flow, where molten metal exits the crucible through the spout's orifice. The spout's geometry (taper, length, diameter) and refractory lining control flow rate, prevent splashing, and maintain thermal integrity. Some advanced designs incorporate stopper rods or slide gate mechanisms for on/off flow control.
材料
High-alumina refractory (e.g.85-95% Al2O3)silicon carbideor zirconia-based ceramicsoften with insulating backup layersmay include graphite or coated steel for structural support.
Length
150-500 mm
Orifice Diameter
20-100 mm
Refractory Thickness
25-75 mm
Thermal Shock Resistance
>30 cycles (ASTM C1171)
Max Operating Temperature
1600-1800°C
标准
ISO 185:2005DIN 1691ASTM A247

常见问题

What is the primary function of a pouring spout on a crucible?

To provide controlled, directional pouring of molten metal, minimizing turbulence, oxidation, and slag entrainment for higher casting quality.

How often should a pouring spout be replaced?

Depends on usage; inspect for cracks, erosion, or thermal degradation after 50-200 pours, or per manufacturer guidelines.

Can pouring spouts be used for all metals?

No, material selection varies: alumina for steel/iron, silicon carbide for non-ferrous, zirconia for reactive alloys like titanium.
