(1)軟輥；肖氏硬度約為30一40，用于開坯機(jī)、大型型鋼軋機(jī)的租軋機(jī)等。

(2)半硬輥：肖氏硬度約為40一60，用于大型、中型、小型型鋼軋機(jī)和鋼板輪機(jī)的租軋機(jī)。

(3)硬面輥：肖氏硬度約為60一85，用于薄板、中板、中型型鋼和小型型鋼軋機(jī)的稿軋機(jī)及四輥軋機(jī)的支撐輥。

(4)特硬輥le氏硬度約為85—100，用于冷軋機(jī)。

(1) soft roll; the hardness of Shaw is about 30 40. It is used for the renting rolling mill of the billet machine and the large steel mill.

(2) semi hard roll: the hardness of the Shaw is about 40 to 60. It is used for the renting rolling mill of large, medium, small type steel mill and steel plate turbine.

(3) hard roll: Shore hardness of about 60 to 85, for supporting roller mill release sheet, plate, medium and small steel mill and four roller mill.

(4) the hardness of the hard roll Le is about 85 - 100 for cold rolling mill.

線材軋機(jī)擁有粗軋機(jī)架和與小型型材軋機(jī)類似的中間機(jī)架。與兩線軋制的小型型材軋機(jī)相比，這些軋機(jī)一般被設(shè)計成可以進(jìn)行高達(dá)4線的同時軋制的切分軋制。然而，目前的發(fā)展趨勢是采用單線的高速軋制。

The wire mill has a roughing mill stand and an intermediate rack similar to a small section mill. Compared with the two section rolling mill, these mills are generally designed for rolling up to 4 lines at the same time. However, the current development trend is single line high-speed rolling.

在粗軋機(jī)架后，中型型材軋機(jī)有兩組連續(xù)的機(jī)架。連續(xù)軋機(jī)，根據(jù)孔型設(shè)計既可以水平布置，也可以立式布置。對于有平行緣的型鋼和槽鋼，還配有機(jī)架。

After the roughing mill, there are two sets of continuous rack in the medium section mill. The continuous rolling mill can be arranged horizontally or vertically according to the pass design. For steel and channel steel with parallel edges, universal frame is also available.
