本文在实验室条件下,对Φ200mm、厚度60mm的耙片进行了液态挤压成形试验。结果表明,在金属型——耐火材料型条件下,耙片成形性最好,为农机耙片提供了生产性试验的依据。
In this paper, under the laboratory conditions, Φ200mm, the thickness of 60mm discs were squeezed liquid forming test. The results show that the hardenability of the harrow is the best under the metal - refractory type condition, which provides the basis for the productive test of agricultural harrow.
