A new kind of large sample plane strain compression technology was introduced. Based on summarizing the shortage of present simulation technology, the experimention method was put forward for large sample plane strain compression technology. The machinery was designed, and the characteristic and function were clarified. Accoding to data of temperature, pressure and displacement were collected by industry control computer, which could be used for simulating different processing parameters of hot rolling strip. Large sample multi-pass plane strain compression was realized by using malleable cast-iron. The results show that large sample plane strain can satisfy with the requests of both micro-analysis and mechanical property analysis for developping new materials and process optimization.
