In recent years, many studies have been carried out on the evaluation of cutting performance of materials by cutting force combined with other parameters. However, these articles only explain the cutting parameters in the cutting process. There is no mention of whether the engine block is cut with gray...

Experimental method and process of gray cast iron for engine cylinder block
The mechanical properties and machinability of gray cast iron samples for engine cylinder block were tested, and the microstructure of the matrix was observed. 1. Determination of mechanical properties of gray cast iron for engine cylinder block The tensile strength test of gray cast iron for engine cylinder block...

Cylinder block casting riser
Chilled iron is the most commonly used chilling material to control the solidification of cylinder block castings. It can be used in combination with the riser. It can be formed as the end, isolate the feeding area of the riser, strengthen the sequential solidification of cylinder block castings, and...

Original casting process scheme of cylinder block
The upper half of the middle cylinder block for a certain type of steam turbine is made of ZG20CrMo, the gross weight of the casting is 6400 kg, and the process yield is 55%. The main structure is composed of cylinder wall with equal wall thickness of 45 mm...

Steam turbine cylinder steel castings
The split flange of steam turbine cylinder block steel casting is the upper and lower half of the cylinder block. Ultrasonic flaw detection is required after the split is processed to meet JB / t9630 2 according to the level 2 requirements of ultrasonic flaw detection and quality classification...

Control measures of sand sticking on the surface of cylinder block castings
1. Defect description The cylinder block is a horizontal horizontal pouring process (as shown in Figure 1), with complex structure and wall thickness of (3.5 ± 0.8) mm. In order to ensure the forming of the cylinder block and reduce the generation of casting defects (pores, etc.), high temperature...

Gray cast iron cylinder block casting
A series of cylinder block castings produced by ZHY casting are specially matched for mainstream models such as Audi, maiteng and Suteng of Volkswagen. They are all typical thin-walled castings. The wall thickness of the water jacket at the thinnest place is about 3 mm, and the material brand...

Optimization of lost foam casting process for cylinder block
Change the pouring position of the cylinder block and place the top surface of the lost foam casting of the cylinder block at the bottom, as shown in Figure 1. The middle injection pouring is adopted, and the pouring system remains unchanged. 1. Mold filling process The filling process...

Numerical simulation of lost foam casting of cylinder block
Import the three-dimensional modeling into ProCAST software in x-t format, repair the surface of the parts in mesh module, and then divide the surface grid of the parts. The grid size of cylinder lost foam casting and gating system is 10mm, and the grid size of sand box is...

Cylinder block structure and lost foam casting process
1. Structural analysis of cylinder block The schematic diagram of a 12 cylinder block is shown in Figure 1. The outline dimension of lost foam casting cylinder block is 1225mm × 800mm × 680mm, casting volume of 0.666m3, mass of lost foam casting cylinder block of 638.2kg, thickness of...
