较小规格的钢筋既能轧制直条也能轧制成线卷。生产者为了保持高的轧制速度和生产效率,喜欢把16mm直径的钢筋连续成卷轧制。但轧机需要有大功率的二次再加热炉才能工作,这使生产成本提高。而钢筋使用者却获得使用方便和易于加工变形的目的。可惜,要圆棒成卷轧制直到目前还不能采用与直棒轧制相同的冷却工艺。这是因为高的精轧速度使必要冷却难于达到以及低温时难以卷绕。现在

Smaller specifications of the bar can be rolled both straight and rolled coils. In order to maintain high rolling speed and production efficiency, producers prefer to roll the 16mm diameter rebar continuously. But the mill needs to have a high-power secondary reheating furnace to work, which makes the production cost increase. The reinforcement users have access to easy to use and easy processing deformation purposes. Unfortunately, it is not possible to use the same cooling process as straight bar rolling until now. This is because high finishing speeds make it difficult to achieve necessary cooling and difficult to wind up at low temperatures. just now
