It is suitable for heating all kinds of black and non-ferrous metal ingot, blank tube and bar.
Equipment structure features:
The function of this product in the hot-rolled seamless steel tube production line is to heat the qualified fixed size blank tube after cutting from normal temperature (20℃) to 1280±5℃ for the perforating process of the perforating unit. Ring furnace is the most ideal industrial furnace type for heating round tube billet in the world. The characteristics of this furnace is that the bottom of the furnace is circular. Under the action of the bottom driving device, the bearing tube billet is rotated from the feeding end to the discharging end, and then the heated tube billet is taken out by the discharging machine from the discharging door. In the process of the billet moving with the bottom of the furnace, it is heated to the qualified discharge temperature through the burner on the wall and top of the furnace, and meets the requirement of temperature uniformity.
Compared with other furnace types, it has the following advantages:
The annular furnace is most suitable for heating round billet tubes and can adapt to complex billet compositions of different diameters and lengths. It is easy to adjust the heating temperature according to the changes of tube billet specifications.
The billet tube is placed on the bottom of the furnace at intervals, the billet can be heated on three sides, the heating time is short, the temperature is uniform, the heating quality is good.
The tube billet rotates with the bottom of the furnace during heating. There is no relative movement between the bottom of the furnace and the friction oxide sheet is not easy to fall off. The furnace has no other openings except for the outside of the discharging door. It has good tightness, less cold air is inhaled and less damage due to oxidation. The blank tube in the furnace can be emptied, also can set aside empty furnace bottom section without charging, easy to replace the blank tube specifications, flexible operation scheduling.
Charging, discharging and furnace operation can run automatically, high degree of mechanization and automation of operation.
