Based on the above investigation, it is determined that the fracture at the axle hole of the front support steel […]

The fracture location is at the hole of the front support steel casting, where the design safety factor is relatively

From Figure 1, it can be seen that the upper part of the front support steel casting shaft hole is

Certain type of 30t excavator has experienced several instances of cracking and failure of the front support during casting. The

The acceleration of urbanization in China has promoted the increasing demand for infrastructure construction such as highways and railways, as

1. Process Measures (1) The riser on the long platform of the support steel casting was originally placed in the

After pouring, the internal quality and surface quality of the IP inner cylinder steel casting meet the technical requirements, which

CAE simulation of casting process can increase design functions, reduce design costs, and shorten design cycles; And continuously optimize the

Due to the small space and large wall thickness in the steam inlet chamber of the inner chamber of the

Due to the adoption of a wall riser process for the medium pressure inner cylinder steel casting, the main core

In order to achieve feeding of the riser to the casting, it is necessary to ensure that the solidification time

Due to the high pouring temperature of steel castings, which typically ranges from 1520 to 1620 ℃, the surface of

The material of the guide rail steel castings is ZG32MnMo. Using the company’s current 3T alkaline arc furnace smelting and

Casting shrinkage refers to the shrinkage of the solidification and cooling process of liquid metal, which causes the dimensions of
