It is widely used in dairy, beer, food, beverage, pharmaceutical and chemical industries. In iron and steel smelting role is particularly prominent. The long nozzle can prevent the secondary oxidation of molten steel and improve the quality of steel.The oxidation products of easily oxidized elements in steel were deposited on the inner wall of the nozzle to prolong its service life.Long nozzle can be used many times to reduce the consumption of refractories.
The nozzle is the part of the frame that is formed in the factory when the model is poured to bond with the part. It is the inlet and outlet for the flow of the thermalized liquid. The molten steel flows into the mold cavity through the nozzle.
Long nozzle: When the steel is poured from the ladle to the intermediate ladle, in order to prevent oxidation and splashing, a long nozzle is installed at the lower end of the sliding nozzle at the bottom of the ladle, with one end connected to the lower nozzle and the other end inserted into the steel of the intermediate ladle for sealing and protecting the pouring.
Intrusive nozzle: In continuous casting technology, in order to improve the quality of cast billets, an intrusive nozzle is installed between the intermediate ladle and the crystallizer.
