Many foundry enterprises also use casting simulation analysis software to improve the process. Xiazezi and others from China shipbuilding industry
Compared with resin sand and sodium silicate sand cast steel process, wet mold clay sand cast steel process has the
The position of the riser at the hook body part of the hook body is improper, and the feeding effect
Mainly analyzes and summarizes ZHY Casting optimized sand casting process from the aspects of product quality, scrap rate, product quantity,
The coupler body of type 17 coupler is a complex medium and small steel casting with the overall size of
Firstly, the basic process flow of trial production of coupler products, the main process equipment and process methods used by
Sand casting product is a kind of defective product. At present, no company at home and abroad can make sand
When the original sand casting process produces the shell casting, the molding, core making, lower core box closing, pouring, sand
The production of wet molding clay sand steel castings abroad has a long history of application and development. According to
During the trial production of coupler steel castings, the process scheme is continuously optimized and the casting quality is continuously
At the initial stage of trial production of hook body and tongue steel castings, the original process scheme is still
It mainly simulates and optimizes the process of two parts: 17 coupler body and 16 coupler tongue, which are important
Firstly, the original sand casting process of 17 type coupler body and 16 type coupler tongue is simulated and analyzed,
The wet molding clay sand process of railway steel castings is a more traditional and difficult to control energy-saving and
In terms of detection methods, GB7233-09 focuses on the near-field area of ultrasonic flaw detection, and adds a near-field resolution
Firstly, cast the steel castings of the coupler according to the original casting process design. The main problems exposed are:
