According to the requirement of modern concrete pavement construction,and the analysis of char - acteristics,performance,application,status of various concrete seam cutting machine,discusses the feasibility of hydraulic seam cutting machine.
根据现代混凝土路面施工对切缝机的要求,以及不同类混凝土切缝机的性能、特点、应用与现状的对比分析,论证了发展液压切缝机的可行性。
The distribution of magnetic field in electromagnetic soft-contact mold with different slit parameters was analyzed through 3-D FEM numerical simulation method.
结果表明,对于部分切缝结晶器,结晶器口部有无盖板对其内部磁场分布的影响不大;增加结晶器切缝数,结晶器内磁场的渗透率、磁感应强度、磁场的有效作用范围及磁场的均匀性都得到增强;切缝宽度对结晶器内部磁场的影响不大;切缝长度越长,磁感应强度越大,磁场的有效作用范围越大。
