钛合金杆拉铸工艺流程
英文回答：
Titanium Alloy Rod Centrifugal Casting Process Flow.
Preheating mold.
The mold is preheated to a temperature of approximately 700 °C (1292 °F) before casting. This preheating helps to reduce thermal shock and cracking of the mold during casting.
Pouring the molten metal.
The molten titanium alloy is poured into the mold at a temperature of approximately 1600 °C (2912 °F). The molten metal is poured into the mold in a controlled manner to avoid splashing and oxidation.
Centrifugal casting.
The mold is then rotated at a high speed, typically between 500 and 1000 rpm. This centrifugal force helps to distribute the molten metal evenly throughout the mold and to remove any trapped air or gas bubbles.
Cooling.
The mold is allowed to cool slowly after casting. This slow cooling helps to prevent cracking of the cast rod.
Post-processing.
The cast rod is then removed from the mold and subjected to post-processing operations such as:
Annealing: Annealing is a heat treatment process that helps to soften the cast rod and improve its ductility.
Machining: Machining is used to finish the cast rod to the desired dimensions and shape.
Inspection: The cast rod is inspected to ensure that it meets the required specifications.

钛合金杆拉铸工艺流程。

预热模具。

铸造前将模具预热至约700 °C (1292 °F) 的温度。

此预热有助于减少铸造过程中模具的热冲击和开裂。

浇注熔融金属。

将熔融钛合金以约1600 °C (2912 °F) 的温度浇注入模具。

将熔融金属控制浇注入模具，以避免飞溅和氧化。

离心铸造。

然后以通常在 500 至 1000 rpm 之间的转速旋转模具。

这种离心力有助于使熔融金属均匀分布在整个模具中，并去除任何夹带的空气或气泡。

冷却。

铸造后让模具缓慢冷却。

这种缓慢冷却有助于防止铸件开裂。

后处理。

然后从模具中取出铸件，并进行后处理操作，例如：
退火，退火是一个热处理过程，有助于软化铸件并提高其延展性。

加工，加工用于将铸件加工成所需的尺寸和形状。

检查，检查铸件以确保其符合所需规格。
