Abstract
A slag-blocking system for torpedo ladles comprises a counterweight, the counterweight is connected with one end of a wire rope, the other end of the wire rope passes through a guiding pipe fixed on a supporting upright and a guiding fixed pulley, and is then connected with one end of a hanging chain, and the other end of the hanging chain passes through a fixed pulley, and is then connected with a U-shaped hanging clamp; both the guiding fixed pulley and the fixed pulley are fixed on an I-shaped crossbeam; the bottom of the U-shaped hanging clamp is connected with a balancing frame, and the right end of the balancing frame is connected with a right chain, and is connected with the right side of a slag-blocking plate through a right U-shaped clamp; and the left end of the balancing frame is connected with a left chain, and is connected with the left side of the slag-blocking plate through a left U-shaped clamp. The slag-blocking system is characterized in that: both ends of the slag-blocking plate are placed in a right L-shaped positioner and a left L-shaped positioner and locked, both the right L-shaped positioner and the left L-shaped positioner are welded on both sides of a tap hole of a torpedo ladle, so that the slag-blocking plate can be turned along with the torpedo ladle, and moreover, a tapping gap is kept between the slag-blocking plate and the lower edge of the tap hole.
Description
Technical field
The present invention relates to iron and steel enterprise's hot metal supply technology field, specifically fish torpedo ladle when of falling iron, it is to avoid the device that scum is poured out.
Background technology
At present, the Molten Iron Transportation mode of known large iron and steel enterprise is transported using fish torpedo ladle, but during fish torpedo ladle molten iron is poured into hot-metal bottle, slag measure is kept away due to lacking, and there is the accumulated slag brought into during by blast furnace casting in fish torpedo ladle while being also poured out.It is understood that chemical element is mainly in scum：(P) and (S), and (P), (S) they are harmful element in steel, and be very difficult in the oxidizing atmosphere of steel-making to remove, so as to cause in steel (P), (S) exceeded finished product percent defective to increase.
The content of the invention
In order to solve existing fish torpedo ladle fall band scum during iron the problem of, keep away slag device the invention provides a kind of fish torpedo ladle simple in construction, easy to use.
The present invention solves the technical scheme that its technical problem is taken, it includes：Counterweight, one end of counterweight connecting steel wire ropes, the steel wire rope other end is through being fixed on after the guide pipe on support post, through the one end for being oriented to fixed pulley reconnection hanging chain, hangs the other end of chain by connecting suspending U type card after fixed pulley；Fixed pulley, fixed pulley is oriented to all to be fixed on drum crossbeam；Balancing stand is connected with below suspending U type card, the right-hand member of balancing stand is connected with right side chain and the right side of slag trap is connected by right side U-shaped card；Left side chain is connected with the left of balancing stand and the left side of slag trap is connected by left side U-shaped card；The two ends of slag trap are placed in right side L-type locating rack and left side L-type locating rack to be lived by pintle hook lock, right side L-type locating rack and left side L-type locating rack are all welded on the both sides of the fish torpedo ladle mouth of falling iron, slag trap is set to follow fish torpedo ladle to rotate together, and the lower edge of slag trap and the mouth of falling iron maintains gap of tapping a blast furnace.
The beneficial effects of the invention are as follows：It is simple in construction, easy to operate, to keep away scum effect good, can effectively improve steel-making product qualified rate.
Brief description of the drawings：
The present invention will be described in detail with reference to the accompanying drawings and examples：
