大型鼓风机机壳的稳定生产
|
摘要
介绍了AV63系列风机机壳铸件的模型构成、技术要求和验收标准。以下机壳为例,阐述了树脂砂地坑组芯造型的铸造工艺。讨论了造型、制芯、合箱和熔炼浇注过程,提出做好产前准备工作,严格操作过程是机壳安全顺利生产的关键。结果表明,通过采取一系列工艺手段,解决了铸件粘砂、披缝等表面品量,尺寸偏差,浇注时跑火、漏底和抬箱等主要缺陷。
The model composition, technical requirements and acceptance criteria of fan housing casting of AV63 series were introduced. The casting process of resin sand pit core molding was described as an example of lower casting. The molding, core-making, box closing and melting and pouring processes are discussed. It was pointed out that the key to the safe and smooth production is to make good prenatal preparation and strict operation process. The results show that by adopting a series of technological means, the main defects such as the surface quality of the casting, such as sand sticking,slabbing and so on, the size deviation, the running of the casting, the bottom leakage and the lifting of the box are solved.
