Materials of jaw plate in jaw crusher and its selection;
颚式破碎机颚板的材质及选择
In order to solve the problem that high manganese steel jaw plate has short servicing life,frequent replacing, low toughness of alloy cast steel jaw plate and being easy to fracture in the use,a new kind of high strength martenitic cast steel whose compositions are 0.
为了解决高锰钢颚板使用寿命短、更换频繁和合金铸钢颚板韧性低、使用中易破断的难题,开发了一种含0。
The crushing jaw plate made of the above bainitic cast steel has three times longer servicing life than that of high manganese steel.
在普通中碳钢中,以硅、锰为主要合金元素,另外加入廉价的含钨、锰、铌、钽和钛等元素的钨渣铁合金,正火后获得了贝氏体组织,具有良好的强韧性和优异的耐磨性,用于制造破碎机颚板,使用寿命比高锰钢提高3倍以上,而生产成本相当。
Using the engineering analysis software ANSYS,a parameter structure model for the mobile jaw body of some type of single toggle jaw crusher was built.
利用有限元软件ANSYS建立了某型号颚式破碎机动颚的参数化模型,将有关结构参数变量指定为优化设计变量,以结构在已知工况下的应力为状态变量,在此基础上采用有限元数值方法,对动颚进行优化设计以减少其重量;同时对优化前后的模型进行了模态分析,以检验优化对结构动特性的影响,从而为实际生产设计部门进行优化结构、节省材料用量提供理论依据。
