This machine is mainly suitable for the samming process of sheep blue wet skin and pig blue wet skin less than too large in width after tanning . through samming of this machine the moisture content of skin is approximately50 % , after samming , the pig skin may be put into next process for accurately splitting , then the sheep skin may be shaved after rolling wood flour , the whole piece of skin pass through the machine once , operation is convenitent and productivity is higher 1800通过式挤水机主要适用于经柔制后的羊皮蓝湿革和张幅不太大的猪皮蓝湿革的挤水工序，经该机挤水后革的水分含量为50左右，挤后猪皮可立即进入下道精密剖层，羊皮经滚木削后进行削匀，两张皮革一次通过，操作方便，生产效率高。
The properties of low carbon steel can be greatly enhanced when its grain size becomes ultrafine . approaches to obtain ultrafine grain size for low carbon steel , such as microalloying , electromagnetic field treatment and thermo - mechanical treatment after rolling , are given in this paper . in addition , the mechanism and technologies of ultrafine granulation are also discussed 低碳钢的性能可通过晶粒超细化得到改善,讨论了低碳钢生产过程中利用微合金化、电磁场处理和轧后加工处理等方法进行的晶粒超细化,讨论了晶粒超细化的作用机理和生产工艺。
A kind of new way for surface rolling processing of stainless steel rod has been put forward , thus made an enhancement on the mechanical properties of surface hardness and fatigue strength of steel rod after rolling and solved the difficult problem on the processing length of steel rod being limited by the bed length of machine tool in the traditional processing method 摘要提出一种新的不锈钢棒表面滚压加工方式，使得滚压后钢棒的表面硬度和疲劳强度等机械性能得到提高，解决了传统加工方式中钢棒加工长度受机床床身限制这一难题。
