The distance between the heating furnace and the phosphorus removal equipment is generally about 5 meters, the water pressure reaches 18Mpa when the phosphorus removal equipment is working, because the water pressure is big, the phosphorus removal water splashes and enters the furnace through the heating furnace tapping hole, causes the damage to the heating furnace body, and affects the service life of the heating furnace. SUMMARY

[0003] The utility model discloses a billet phosphorus removal water baffle device, high -temperature billet can effectively block the phosphorus removal water into the heating furnace in the phosphorus removal process, thereby protecting the furnace body, and the problem existing in the background art is solved.

[0004] The utility model discloses a technical scheme is:

[0005] A billet phosphorus removal water baffle device, including passageway, water baffle and water baffle iron chain curtain, passageway sets up between the billet heating furnace and the billet phosphorus removal equipment, and the passageway bottom is the conveying roller way of billet, according to the running direction of billet, in passageway sequentially sets up several water baffle and several water baffle iron chain curtains.

[0006] The water baffle in the passageway is two arranged in advance and after, and the water baffle iron chain curtain in the passageway is three arranged in advance and after.

[0007] The water baffle in the passageway is rectangular plate, and the upper end of the rectangular plate is rotatably connected to the top of the passageway through an iron rod, and the distance between the lower end of the rectangular plate and the upper plane of the roller way is greater than the outer dimension of the billet.

[0008] The water baffle iron chain curtain in the passageway is a chain curtain formed by a plurality of iron chains arranged side by side, and the upper end of the chain curtain is fixed to the top of the passageway, and the distance between the lower end of the chain curtain and the upper plane of the roller way is greater than the outer dimension of the billet.

[0009] The end of the passageway close to the heating furnace is a billet inlet, and the end of the passageway close to the phosphorus removal equipment is a billet outlet, and the billet inlet and the billet outlet are both gradually smaller horn mouths.

[0010] The utility model discloses the beneficial effects are: high -temperature billet can effectively block the phosphorus removal water into the heating furnace in the phosphorus removal process, thereby protecting the furnace body, avoiding the damage to the heating furnace body, prolonging the service life of the heating furnace.

[0015] The present invention will be further described below with reference to the accompanying drawings and examples.

[0016] Refer to the attached Figure 1 、 2 3. A billet dephosphorization water retaining device comprises a channel 1, a water retaining plate 2 and a water retaining iron chain curtain 3. The channel 1 is arranged between the billet heating furnace and the billet dephosphorization equipment. The bottom of the channel 1 is a conveying roller for the billet. According to the running direction of the billet, several water retaining plates 2 and several water retaining iron chain curtains 3 are arranged in sequence in the channel 1.

[0017] In this embodiment, refer to the attached Figure 1 、 2 3. The end of channel 1 close to the heating furnace is the billet inlet A, and the end of channel 1 close to the dephosphorization equipment is the billet outlet B. Both the billet inlet A and the billet outlet B are trumpet mouths that gradually become smaller.

[0018] The two water retaining plates 2 in channel 1 are arranged in tandem, forming two retaining walls close to the heating furnace, effectively preventing water from entering the furnace. The distance between the two retaining walls is 80 mm, and the distance between the left water retaining plate 2 and the end of the billet inlet A is 70 mm. Both water retaining plates 2 are rectangular plates, and their upper ends are rotatably connected to the top of channel 1 via iron rods. The lower ends of the water retaining plates 2 can swing freely, and the distance from the lower end to the upper surface of the roller table is greater than the outer dimensions of the billet to avoid impact with the billet.

[0019] Three water-blocking chain curtains 3 are arranged in sequence within channel 1. Each chain curtain 3 is composed of multiple chains arranged side by side. The upper end of the chain curtain is fixed to the top of channel 1, and the distance between the lower end of the chain curtain and the upper surface of the roller table is greater than the outer dimensions of the steel billet to avoid impact with the steel billet. The water-blocking chain curtains 3 can disperse the pressure of the incoming high-pressure water, preventing the high-pressure water and iron oxide scale from splashing everywhere.
