Slag-blocking system for torpedo ladles

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 [0001] The invention relates to the technical field of molten iron supply technology for iron and steel enterprises, in particular to a device for preventing iron slag from pouring out when a torpedo tank is pouring iron. Background technique [0002] At present, the known large-scale iron and steel enterprises all use torpedo tanks to transport molten iron, but in the process of pouring the torpedo tank molten iron into the molten iron tank, due to the lack of slag avoidance measures, there is a backlog of bringing the blast furnace iron into the torpedo tank. The slag is also poured out at the same time. We know that the chemical elements in iron slag are mainly: (P) and (S), while [P] and [S] are harmful elements in steel, and are difficult to remove in the oxidizing atmosphere of steelmaking, resulting in [ P〕,〔S〕The increase of the scrap rate of finished products exceeding the standard. Contents of the invention [0003] In order to solve the proble...
