Abstract
The present invention provides a novel apparatus for charging molten iron in an continuous steel-making electric furnace, which is characterized in that one end of a chute not provided with a chute cover, an ingress door and an egress door of a molten iron chute is provided with a U-shaped groove built on the inner wall of a furnace by refractory bricks, the U-shaped groove and the chute are in butt joint, the interfaces are connected by the refractory brick, and a gap is filled with refractory clay. The novel apparatus has the advantages of high safety and reliability, convenient cleanness and maintenance, cost reduction, realization of molten iron charging continuity and enhancement of work efficiency and provides an advanced technology in steel-making industry.
Description
Affiliated technical field
The present invention relates to a kind of device toward the interior hot metal charging of continuous steelmaking (Consteel) electric furnace.
Background technology
In the prior art, the device of hot metal charging comprises that chute is added a cover, molten iron inlet/outlet, chute colling end etc., because complex structure makes the operative employee meet difficulty to the maintenance and the cleaning of molten iron device; Owing to the water cooling end that stretches in the stove is leaked by the puncture of the arc light of electric furnace easily, cause slag to splash and pile up sticking dead chute turnover doorway in addition, What is more causes molten steel blast serious accident.
Summary of the invention
Purpose of the present invention is intended to overcome the deficiencies in the prior art and a kind of safe, device of safeguarding and clearing up easy and fast charging molten iron in electric furnace for continuously smelting steel simple to operate is provided.
The object of the present invention is achieved like this:
A kind of device of charging molten iron in electric furnace for continuously smelting steel, comprise chute main frame 2, chute top 3, an end that it is characterized in that not adding the chute of groove lid and Molten iron chute inlet/outlet is the U type groove 1 of building by laying bricks or stones with refractory brick in the burner hearth of inboard, furnace wall, U type groove 1 docks with chute, interface connects with refractory brick, fills in the slit with refractory mortar.
Description of drawings
The invention will be further described below by drawings and Examples:
Fig. 1 is the A-A sectional view of structure of the present invention.
Fig. 2 is the vertical view of structure of the present invention.
1 is U type groove among the figure, and 2 is the chute main frame, and 3 is the chute top, and 4 is refractory brick (square), and 5 is refractory mortar (inverted triangle), and 6 is bolt.
Embodiment
During enforcement, do not establish chute lid, molten iron inlet/outlet and water cooling end, chute top 3 usefulness bolts 6 are fixed with chute main frame 2, build by laying bricks or stones as permanent layer earlier, then be coated with last layer, on the stove inwall, build U type groove 1 by laying bricks or stones with refractory brick with refractory mortar with refractory brick 4, chute integral body is hung toward the place, furnace wall, with U type groove on the furnace wall to connecting, interface is with refractory brick 4 transition, then with refractory mortar everywhere seam tamp and fill and lead up.
The present invention is safe and reliable, cleaning and easy to maintenance, has both prolonged the life-span of the device of molten iron, greatly reduces cost again, realizes the continuity of hot metal charging, has improved working efficiency, is the advanced means in the Steel industry.
Claims (1)
