Abstract
The utility model discloses a ball club combined type slag bridge, comprising a ball arc shape body 1, and a stopper head 2. The ball club combined type slag bridge is characterized in that the stopper head 2 is vertically fixed to the arc face middle part of the ball arc shape body 1 and is combined with the ball arc shape body 1 as a whole, and a cylinder shape casting pig 3 is embedded in the stopper head 2. The ball club combined type slag bridge has the advantages of simplifying fabrication process, reducing production cost, accurately delivering at the upper part of the tap hole, reducing manual delivery risk, and lightening operator labor intensity.
Description
Technical field
The utility model relates to a kind of improvement of converter steel tapping slag bridge, specifically a kind of bat combined type slag stopper.
Background technology
In STEELMAKING PRODUCTION, enter ladle for preventing slag, cause the molten steel rephosphorization, increase the impurity and the gas content of molten steel, be everlasting the converter tapping later stage, adopt certain slag-blocking apparatus, as slag retaining cap, slag-blocking ball, floating plug etc., block slag liquid, to protect the purity of molten steel.Present employed slag-blocking ball, slag retaining cap, floating plug are made by ingot pig outsourcing refractory materials, smooth outer surface, though the energy pushing off the slag also exists significantly not enough: the one, when blocking slag liquid, also blocked tap hole, molten steel can not have been gone out, influence molten steel output; Two when being to use smooth ball, because tap hole touches, washes away after strain, expansion repeatedly being soaked by molten steel, furnace lining is soaked irregular after spray repair after touch, and slag-blocking ball can't coincide with the tap hole plane, causes down slag, the pollution molten steel; The 3rd, center of gravity is higher, instability; The 4th, can not point to tap hole all the time, guidance quality is poor.
Summary of the invention
The purpose of this utility model is to provide a kind of can overcome above deficiency, stable gravity center, is difficult for the bat combined type slag stopper that deflection, guidance quality are strong, shoot straight.
For reaching above purpose, the technical scheme that the utility model adopted is: this bat combined type slag stopper, constitute by ball arcuation body and stopper head, it is characterized in that the stopper head is vertically fixed on the cambered surface middle part of ball arcuation body, and be combined as a whole, ball arcuation body and stopper head are all made of refractory materials, embedding column ingot pig in the stopper head, center of gravity is moved down, and make the stopper head play tangible guide effect.The utility model is also implemented by following measure: the diameter of described stopper head is the 1/2-4/5 of tap hole interior diameter, because the stopper head is thinner than tap hole, when the stopper head stretched into tap hole, molten steel can flow out, but slag liquid come-up; The upper surface of described ball arcuation body is a disk, and the diameter of disk is four times of stopper head diameter, and presenting grows crosswise erects shape short, that the top area is big, the bottom area is little, owing to up big and down small, has increased the suspending power of ball arcuation body, so more stable; Establish vertical vertical loading board on the upper surface of ball arcuation body, establish suspension ring in the upper end of vertical loading board, vertical loading board can be made of Deformed Steel Bars, and the lower end is embedded in the ball arcuation body.When using the utility model, adopt ad hoc throwing mechanism, choose suspension ring, the tap hole top that this slag stopper is sent in the converter gets final product, so placement position is accurate.
The beneficial effects of the utility model are: since this slag stopper have last area big, down little, the perpendicular weak point of growing crosswise of area, center of gravity below constructional feature, so between the top molten steel and slag liquid that swim in tap hole that this slag stopper can be stable, and because the stable guide effect of stopper head, can improve the hit rate of this slag stopper; In addition, this slag stopper Mold Making is simple, has simplified manufacture craft, has reduced production cost; This slag stopper is thrown in by throwing mechanism, can throw in above tap hole accurately, has reduced the danger of artificial input, has alleviated operator's labour intensity.

Embodiment
Make the utility model with reference to accompanying drawing 1,2,3.This bat combined type slag stopper, constitute by ball arcuation body 1 and stopper head 2, stopper head 2 is vertically fixed on the cambered surface middle part of ball arcuation body 1, and be combined as a whole, ball arcuation body 1 and stopper head 2 are all made of refractory materials, embedding column ingot pig 3 moves down center of gravity in stopper head 2, and makes 2 tangible guide effects of stopper head.The diameter of described stopper head 2 is the 1/2-4/5 of tap hole interior diameter, because stopper head 2 is thinner than tap hole, when stopper head 2 stretched into tap hole, molten steel can flow out, but slag liquid come-up; The upper surface of described ball arcuation body 1 is a disk, and the diameter of disk is four times of stopper head 2 diameters, and presenting grows crosswise erects shape short, that the top area is big, the bottom area is little, owing to up big and down small, has increased the suspending power of ball arcuation body 1, so more stable; Establish vertical vertical loading board 4 on the upper surface of ball arcuation body 1, suspension ring 5 are established in the upper end of vertical loading board 4, and vertical loading board 4 can be made of Deformed Steel Bars, and the lower end is embedded in the ball arcuation body 1.
Claims (2)
1, a kind of bat combined type slag stopper is made of ball arcuation body (1) and stopper head (2), it is characterized in that stopper head (2) is vertically fixed on the cambered surface middle part of ball arcuation body (1), and is combined as a whole embedding column ingot pig (3) in stopper head (2).
2, bat combined type slag stopper according to claim 1, the diameter that it is characterized in that described stopper head (2) is the 1/2-4/5 of tap hole interior diameter; The upper surface of described ball arcuation body (1) is a disk, and the diameter of disk is four times of stopper head (2) diameter, establishes vertical vertical loading board (4) on the upper surface of ball arcuation body (1), establishes suspension ring (5) in the upper end of vertical loading board (4).
