A main machine base of a sizing mill for manufacturing seamless steel pipe features the existing C-shaped machine base is divided into lower machine base, upper transverse beam, supporting arch, and laterial supporters, and all of them are connected by the connecting parts to become a combined body.
Description
Technical field: [0001] The invention belongs to the technical field of seamless steel pipe production equipment, and in particular relates to a main base of a sizing machine for producing seamless steel pipes. Background technique: [0002] At present, sizing machines for producing seamless steel pipes at home and abroad can be divided into two types: less-stand and multi-stand, and less-stand sizing machines can be divided into two types: adjustable up and down the rolling center line and non-adjustable. When the front and rear roller tables of the sizing machine are fixed, in order to meet the needs of the production of steel pipes of different specifications, an adjustable sizing machine on the rolling center line must be used. This sizing machine adopts a C-shaped integral frame, as shown in Figure 1. [0003] The disadvantages of this C-shaped integral machine base are large volume, heavy weight, complex shape, many processing parts, and inconvenient manufacturing and ...
