This standard is a revision of the type and basic parameters of ZBJ62024.-8 portable building cross rolling mill. The technical content of this standard is basically consistent with that of ZBJ62034-.-89, and it has only been re-edited according to relevant regulations. This standard shall be implemented on January 1, 2000, and this standard shall replace ZBJ62024-89 from the date of implementation. This standard is proposed and managed by the National Bureau of Machinery Standardization Technical Committee. The sponsor of this standard is Jinan Casting and Forging Machinery Research Institute. This standard was first issued in January 1989. National Machinery Industry Standard of the People's Republic of China Types and Basic Parameters of Die-casting Machines The standard specifies the types and basic parameters of die-casting machines. This standard is applicable to die-casting machines for hot-rolled parts and plated parts. 2 Type
