The practicability of the guardrail in transportation is also the practical application of the cast iron guardrail; it can effectively carry out safe transportation, reduce the limiting factors of the terrain, help reduce the use of the project, and the unique terrain restrictions.
The structure of the guardrail is more complete and has a good practical effect。 It has a good grid structure features, and in the appearance of the formation, it also has a good appreciation value, help more significantly to beautify the constructive significance of the project。
Casting technology is based on the structure, weight and size of castings, casting alloy characteristics and production conditions, selecting suitable parting surface and molding, core making method, reasonable setting casting bar, cold iron, riser and pouring system, so as to ensure the quality of castings。
The applicability of the guardrail is strong, it will not be affected by the terrain undulating; it can be well adapted to various terrain, and also has a more significant use performance for some unusual zones, such as mountain and slope, and more effective display in the engineering facilities.
In addition to determining the geometry and size of cast iron parts according to working conditions and metal material properties, it is necessary to consider the rationality of the design from the angle of casting alloy and casting process characteristics, that is, obvious size effect, solidification, shrinkage, stress and so on, so as to avoid or reduce the segregation and change of the composition of cast iron。 The formation of defects such as shape, cracking, etc。
