As the thickness and hardness of CCSA bulk freighter steel increase, the tendency to crack at the cutting edge increases. In order to prevent the CCSA bulk freighter steel from cutting cracks, preheating should be carried out before CCSA bulk freighter steel cutting. Special attention should be paid to preheating to make the entire CCSA bulk freighter steel interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole CCSA bulk freighter steel cannot be preheated, the partial preheating method can be used instead.
The Qatar Railways company launched a tender for designing ,construction and completion of Green Line Project. Our company has participated in the bidding from Qatar Railway Company since May, 2016. A delegation from project visited several famous CCSA bulk freighter steel pipe mill in China for 15 days in July,2016. Of course the delegations had visited our pipe mill.
42CrMo alloy steel CCSA bulk freighter steel: low temperature tempering welding performance thermal processingThe heating temperature is 1150 ~1200°C, the starting temperature is 1130 ~1180°C, the ending temperature is> 850°C, and when φ> 50mm, slow cooling. The normalizing temperature is 850~900°C, and the furnace is air cooled. High temperature tempering: Tempering temperature is 680~700°C, and it is air-cooled from the furnace.
