News of Kizilsu 35CrMo alloy steel pipe
The 15CrMo alloy tube Market businessmen feel that the market price is still hanging upside down, and they have no intention to reduce the price. Moreover, everyone will buy up rather than down. The price drop will only cause more losses to the interests of the merchants, so the price will remain consolidation. From the recent market situation, the market specifications are complete. From the perspective of local downstream demand, the scarcity of transactions is the main factor limiting the price rise in local markets. However, at present, the overall price of domestic mainstream market is also difficult to loosen in a short period of time due to the support of peripheral market prices. Due to the small improvement of terminal demand, although businesses generally raise the current market price, the mentality of 15CrMo alloy tube is not very optimistic, and there are more cases of cautious shipment. It is expected that the prices in the mainstream market will continue to run smoothly in the short term.

Knowledge of Kizilsu 35CrMo alloy steel pipe
When the steel pipe is sizing by the micro tension reducing mill, the wall thickness of the steel pipe is uneven due to the transverse deformation of the metal (along the radial flow), which makes the inner hole of the cross-section of the steel pipe appear "hexagonal", commonly known as "inner hexagonal". The "inner hexagonal" is the result of uneven transverse deformation of metal and a special form of uneven wall thickness of steel pipe.
Xining Special Steel Group Co., Ltd. (hereinafter referred to as Xining Special Steel (600117, Guba)) produces hot-rolled steel pipes. The maximum reduction rate of single stand of the mill is 3.5%, and the average tension coefficient is less than 0.48. The diameter and wall thickness of the steel pipe can reach the final product size by adopting micro tension rolling, 14 stands of three roller type centralized differential transmission of two motors. However, when this set of equipment is used to roll small-diameter thick wall steel pipes, it is easy to have "inner hexagonal" defects, which seriously affect the wall thickness and inner diameter accuracy. This work mainly through adjusting the reducing rate and modifying the pass parameters of the reducing mill, the developed production process can effectively reduce the "hexagonal" defects.
