Description

technical field [0001] The invention belongs to the technical field of workpiece casting, and relates to a casting sand box. Background technique [0002] Casting is the method of melting metal, making molds, pouring molten metal into molds, and obtaining blanks of metal parts with certain shapes, sizes and properties after solidification; it can also be said to melt metals that meet certain requirements and pour them into In the mold, the process of obtaining a casting with a predetermined shape, size and performance after cooling, solidification, and cleaning treatment. Slender structural castings refer to structural parts with large length and length-to-width ratios. Generally, the wall thickness varies greatly and the dimensional accuracy is required to be high. Due to factors such as differences in wall thickness, differences in the order of contact with cooling media, and inhomogeneity in the temperature field, the cooling rates of the upper and lower surfaces and dif...
