Product classification
1. According to the rolling process
The classification of rolling mill reducers is determined by rolling process, which is mainly divided into four types: west mark SMS model, MORGAN model, POMINI model, DANIELI model and so on.
2. Arrange accordingly
In general, the rolling of bar and wire is arranged alternately horizontally and vertically, so that the billet can be rolled in four directions, up and down, to improve the overall mechanical performance of the billet. Horizontal rolling mill is called h-type rolling mill (H is the first letter of the English word "horizontal"). The vertical rolling mill is called V type rolling mill (V is the initial letter of vertical), and the reducer inside is called V type reducer. In addition, there is an H/V flat-stand transfer mill, which can be used to determine whether it is horizontal or vertical.
