High speed steel (M2) strip may be successfully produced by direct cast-rolling process. The cast -rolling mill used in the experiments is a 2-high mill consisting of two hollow rolls made from steel with internal water ooling. The molten steel is poured into the roll gap, where it is soon so-lidified and ro1led into strip. After delivered from the roll gap, the strip is immediately sheared into pieces and rolled with various reductions on a rolling mill. The surface...

High speed steel (M2) strip may be successfully produced by direct cast-rolling process. The cast -rolling mill used in the experiments is a 2-high mill consisting of two hollow rolls made from steel with internal water ooling. The molten steel is poured into the roll gap, where it is soon so-lidified and ro1led into strip. After delivered from the roll gap, the strip is immediately sheared into pieces and rolled with various reductions on a rolling mill. The surface quality and formability may be satisfactory if the optimum process parameters are adopted. The microstructure and mechanical properties of milling cutter made from the M2 strips thus obtained are even better thanthose of the conventional M2 milling cutters.

高速钢M2薄板可以成功地用直接铸轧工艺进行生产。实验所用的铸轧机由内部水冷的两辊式轧机构成。钢水浇注到辊缝中,在辊缝中钢水快速凝固并轧制成钢带。出轧机后,钢带马上剪切成段,并在另一架轧机上以不同的压下量进行轧制.如果所选的工艺参数合理的话,则表面质量和成形性能都是令人满意的.用铸轧高速钢薄板所做的切削刀具的显微组织和机械性能都优于用常规工艺生产的M2高速钢刀具的上述指标。

The tests of inside stripping layer method are conducted on the cold simulation rolls whose types,sizes,material,working and treating methods are different.The distribution curves of the residual stresses in the original roll and the rolls with a drilled or expanded hole are drawn.The fictitious drilling hole method and stripping layer of the hollow roll method are put forward, which have developed the Sachs method. The residual stress can be reduced by drilling the central hole with machining method or...

The devices to obtain semi-solid steel meterial and directly roll and form were designed by ourselves.The mill was installed vertically,and the hollow rolls which were made of globular graphite cast iron can be cooled by water, all of these can meet the experimental requisition of direct rolling and forming of semi-solid steel material,and the microstructure and property of the rolled products also meet the requirements. The experiments and study sugges-te that to transport homogeneous and steady semi-solid slurry quantificationally is the key one among the factros which affect the technologic stability of the semi-solid slurry rheorolling and forming, and the other factors will also affect the microstructure and property of rolled products.

自行设计和制造出一套半固态钢铁材料制备与直接轧制装置。采用重直于水平面的布置方式,有空心水冷球墨轧辊等设备条件,可满足半固态钢铁材料直接轧制成型的试验要求,可轧制出所需内部组织和性能的产品。通过试验研究发现,影响半固态浆料流变轧制成型工艺稳定性的因素中,均匀稳定的半固态浆料定量输送技术是直接轧制成型工艺的技术关键。其他一些因素还会直接影响到轧制产品的组织及性能。
