The whole process of hot-rolled seamless steel pipe production process
The production of hot-rolled seamless steel pipes is a kind of seamless steel pipe production process, and it is also the most common and simplest seamless steel pipe production process. Seamless steel pipes with an outer diameter of 30mm or more can be produced by hot-rolling, the largest domestic seamless steel pipe with an outer diameter The hot-rolled production is about 760mm, and the large outer diameter can only be hot-expanded.
The production process of hot-rolled seamless steel pipe is roughly as follows:
1 Circular hacksaw steel-2 large furnace burning steel-3 round steel perforation-4 tube billet hot rolling-5 steel pipe straightening-6 steel pipe saw head-7 finished steel pipe packaging. The above is the most common process in hot rolling production. Of course, there are also different hot rolling productions. Some manufacturers do not need hot rolling after piercing, but only sizing the tube billet. Some manufacturers hot rolling mill plus mandrel hot rolling , So the steel pipe is more standard, the most common is hot rolling without mandrel. Some manufacturers are ball rolling production.
