| Abstract: | This paper studies the production technology and microstructure of M35 forged round steel are studied.By adopting electroslag remelting and forging hammer forging after multi electrode welding,high quality M35 round steel can be produced.By inspecting the edge,radius 1/2 and center of the finished round steel,the heterogeneity and grain size of the longitudinal eutectic carbide are tested,which shows that the production technology has obvious improvement on the microstructure of M35 forged round steel good,can satisfy the customer to the high speed steel culting tool enhancement cutting speed and the processing quality.lengthens the cutting tool life request. |
