Beschreibung
Zusammenfassung:	The invention provides a cast TBM cutter box and a preparation method. The cutter box is in a three-layer composite form of an upper cutter holder, a middle cutter holder and a lower cutter holder, the upper cutter holder adopts a high-toughness wear-resistant steel material, the middle cutter holder adopts a high-strength alloy steel material, the lower cutter holder adopts a structural steel material, and the upper cutter holder, the middle cutter holder and the lower cutter holder are combined together through a casting method of multi-metal composite materials. According to the cast TBM cutter box and the preparation method, the cutter box is divided into a three-layer cutter holder composite form of the upper cutter holder, the middle cutter holder and the lower cutter holder, and thecutter box is completed through a casting process; compared with a traditional forging and welding mode, the machining allowance of the cutter box is reduced, and the influence of welding stress is eliminated; a high-carbon
