摘　　要：针对传统的铸造渣包存在易开裂、使用寿命短等问题,提出了一种焊接式渣包设计方法。首先根据产品性能与功能需求,对渣包进行结构设计,然后通过渣包设计参数进行模型壁厚计算,最后在不影响渣包整体分析结果,对产品模型简化处理,运用有限元模拟分析渣包在静力载荷与热应力作用下的应力、应变。结果表明,所设计的渣包强度、硬度符合实际技术需求,渣包应用实际工程效果良好。Aiming at the problem that the traditional cast slag bag is easy to crack for poor weldability and short service life,a kind of welding slag design method is proposed. Firstly,the structural design of the slag bag is carried out according to the product performance and function requirements. Then,the model wall thickness is calculated by the design parameters of the slag bag. Finally,without no influence on the overall analysis results of the slag package,the product model is simplified and the finite element simulation is used to analyze the slag Stress and strain analysis obtained under static load and thermal stress. It shows that the slag package strength,hardness meets the actual design requirements,and slag package application of practical engineering effect is good.
