Advantages 

Compared to traditional production process, the hot rolling process of flat welding flange  has the following advantages:

1). Hot rolling process can be done at a time, with stable quality of final products
2). Multi-coil producing, good production rate, high efficiency
3). High precision, good flatness, high qualified rate
4). Specification of flange is adjustable as customers' demand
5). Reduce the consumption raw materials, solve the problem of line segments in the head and tail, make full use of raw materials, compared with the traditional process, the new raised face flange developed by Changtong can save about 24% raw materials
6). Energy saving and low consumption, compared to traditional process, Using the new production method can save 60% coal  and 40% electricity.
