During installation, firstly, the discharge port base 1 is welded with the furnace body, so that the square through hole 1-1 is aligned with the square hole of the furnace body, then the discharge port outer plate 2 and the discharge center opening 3 are fixed by using bolts, a hydraulic 4-cylinder and a gate post 5 structure are installed in a close connection mode, and finally, a hydraulic station system and a water cooling system are installed.
According to the invention, the 32-centimeter hollow water-cooling structure is used for the discharge port base 1, the discharge port base 1 is used as a part directly contacting with a furnace body, and the requirement on stability is very high, so that the discharge port base 1 is specially designed in a water-cooling structure and is provided with the water inlet 1-3 and the water outlet 1-4, the water-cooling cavity in the discharge port base 1 controls the flow rate of cooling water through a plurality of T-shaped clapboards 1-2, so that the flow rate around the square through hole 1-1 is slowed down, the cooling efficiency is greatly improved, meanwhile, the discharge port base 1 is connected with the whole discharge port outer plate 2 through bolts, the discharge port 3 can be integrally replaced within 30 minutes if emergency occurs, any special tool is not needed in the replacement process, the operation is convenient and fast, and the production line can be rapidly recovered.
The discharge port outer plate 2 is one of components of a discharge port device, is connected with a discharge port base 1 through a bolt, and adopts a special annular water cooling structure inside. The internal water cooling adopts a side-in and side-out structure (one side is provided with a water inlet 21, the other side is provided with a water outlet 22), the water is guided by an internal guide plate to enter a central opening for water cooling, the central opening 23 position where the flow flows can be cooled in an all-round way, and the annular guide cooling structure can avoid the phenomenon of uneven cooling caused by a common structure.
The outer structure of the inlet 32 of the discharging center opening 3 is conical, and the outlet is matched and assembled with the conical hole in the outlet of the discharging outlet outer plate 2, so that the discharging center opening 3 and the discharging outer plate 2 can be seamlessly attached, and the sealing effect is achieved. Traditional discharge gate export shape is circular, when the adjusting valve door is opened, reciprocates when the flashboard, and the ejection of compact sectional area and the flashboard height of circular discharge gate become quadratic function relation, if the flashboard height is close when circular port central altitude, micro-regulation will cause the ejection of compact area of ejection of compact central altitude to change by a wide margin, stability when very big influence flow control. The outlet 31 of the invention is designed to be in the shape of a long round hole (the middle of a semicircular hole positioned at the upper end and the lower end is connected with a rectangular hole), when the flashboard is positioned in the height of two parallel lines of the long round hole and the height is adjusted, the discharge sectional area of the long round discharge hole and the height of the flashboard form a linear function relationship, and the stability of flow adjustment is greatly improved.
