模具旋转设备

混凝土和应力混凝土轨枕多半是在模具旋转设备上制成。在设备内模具以旋转的方式运行,并在带有货架和堆垛机的硬化室内硬化混凝土预制件。与固定生产相比,较高的生产效率和相对较低的成本是其最明显的优势。
原则上可分为两个生产工艺:
1. 即时脱模:
混凝土浇注完成后,轨枕立即从轨枕模具中脱模,也就是说,在模具外部完成混凝土的硬化。在应力混凝土轨枕生产过程中,应力钢丝在烘干过程完成后被嵌入轨枕内,并施加预应力。
2. 后脱模:
混凝土烘干在轨枕模具内完成。在应力混凝土轨枕生产过程中,应力钢丝在浇注和压缩混凝土前已嵌入模具内,并施加预应力。烘干过程结束后,解除应力钢丝预应力,此时应力已嵌入轨枕。

From 0 to 450,000 Prestressed Concrete Sleepers
One of the most modern automated circulation plants for railroad sleepers, located in Afyon, Turkey has been taken into operation. Inkol Insaat is set to produce in future 450,000 prestressed concrete sleepers annually in two-shift operation. Thanks to its know-how in plant technology, Vollert Anlagenbau, the specialist in precast concrete plants realized the complete production plant in a mere 6 months from receipt of the order.

Sleeper factory for Manufacturing Monoblock LVT
Tribeton® - a brand name belonging to Creabeton Materiaux AG in Switzerland – wished to change their monoblock production method from conventional to self-compacting concrete. Eltecna AG, Zürich, and Vollert Anlagenbau GmbH, Weinsberg, (Germany) gained the contract to develop and supply a new circulation system for manufacturing sleepers. In essence, the LVT (Low Vibration Track) monoblocks for the Gotthard base tunnel are to be manufactured with this system.

采用后脱模工艺的应力混凝土轨枕的生产
经 2002 年内部研究 Leonhard Moll 混凝土工厂于 2002 年末决定采用后脱模工艺应力混凝土生产系统,该项研究主要针对应力混凝土轨枕的生产进行市场调研,其中包括成本、质量和能源的使用。Moll 公司汲取过去生产应力混凝土轨枕的宝贵经验,并将其与沃乐特公司的建筑设备工程技术要领相结合。从成本、质量和能源消耗的角度来看,其成果在全球范围内已作为一个全新的标准。
