Description

Steel slag receiving overflow tank capable of synchronously moving with tundish

Technical Field

The utility model relates to the technical field of continuous casting equipment, in particular to a steel slag receiving overflow tank capable of synchronously moving with a tundish.

Background

When the existing slag pit is built on a platform, a trolley track in the platform is heated to deform, the platform is heated to collapse, the bottom of the slag pit is of a concrete structure, the bottom is loose due to long-term high-temperature erosion, the hidden danger that liquid steel slag flows into a secondary cooling chamber (a power distribution chamber) exists, the slag in the tundish needs to flow into the slag pit through a slag runner, the slag runner is erected on two cross beams which are high and low in the front and at the back, the serious potential safety hazard that people are injured due to sliding exists, the slag is discharged at least twice in each production, the slag runner is easily heated to deform and needs to be replaced periodically, the refractory material on the slag runner needs to be knotted periodically for maintenance, the slag in the slag runner needs to be cleaned up by entering the rear side of the tundish after each slag discharge, the next slag discharge is convenient, the labor intensity of operators is increased, because the rear side temperature is high, the potential safety hazard of high-temperature burning and scalding exists, and the potential safety hazard of object striking exists because the ladle is arranged above the tundish.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a can with middle package synchronous motion connect slag overflow jar, solved the above-mentioned potential safety hazard that the sediment operation brought and alleviateed workman's intensity of labour.

In order to achieve the above purpose, the following technical scheme is provided:

the utility model provides a can with middle package synchronous movement connect slag overflow jar, sets up on welded base on the car of well package to be located the below of middle package slag tap, overflow jar structure includes a jar body, hangers, dry sediment and rings, the cross-section of jar body is for falling equilateral trapezoid, and its inner wall forms an contained angle A with the vertical direction, the hangers has four, and two bisymmetry sets up in the outer wall top of jar body both sides, dry sediment is laid in jar internal portion and has certain thickness, rings are rectangular pyramid frame construction, place in dry sediment upper surface.

Preferably, the included angle A ranges from 30 degrees to 45 degrees.

Preferably, the height of the hanging ring is greater than that of the tank body.

Preferably, the dry slag is dry steel slag, and the paving thickness is more than or equal to 200 mm.

The utility model has the advantages that:

the utility model discloses cancelled traditional scum groove and pit, avoided the platform to sink, the track warp and frequently change the problem in scum groove, directly used overflow jar to connect liquid slag greatly, the overflow jar can not warp, and repeatability uses, saves manufacturing cost, has avoided all needing artifical clearance after arranging sediment simultaneously at every turn to flow the potential safety hazard in scum groove and bring, has alleviateed workman intensity of labour.

FIG. 2 is a cross-sectional view of FIG. 1;

fig. 3 is a schematic view of an embodiment of the present invention;

the reference symbols shown in the figures are: 1-tank body, 2-hangers, 3-dry slag, 4-rings, 5-base, 6-tundish slag flowing port and 7-tundish car.

Detailed Description

The following describes the present design in detail with reference to the accompanying drawings.

As shown in fig. 1-3, a steel slag receiving overflow tank capable of moving synchronously with a tundish is arranged on a base 5 welded on a tundish car 7 and located below a tundish slag flowing port 6, the overflow tank structure comprises a tank body 1, lugs 2, dry slag 3 and a hanging ring 4, the cross section of the tank body 1 is in an inverted equilateral trapezoid shape, an included angle A is formed between the inner wall of the tank body and the vertical direction, the included angle A ranges from 30 to 45 degrees, the lugs 2 are four, the dry slag 3 is symmetrically arranged at the tops of the outer walls of two sides of the tank body 1 in pairs, the dry slag 3 is laid inside the tank body 1 and has a certain thickness, the dry slag 3 is dry steel slag, the laying thickness is larger than or equal to 200mm, the overflow of the liquid steel slag is prevented from being adhered to the overflow tank, the hanging ring 4 is in a rectangular pyramid frame structure and is placed on the upper surface of the dry slag 3, and the height of the hanging ring 4 is larger than that of the tank body 1.

Examples

As shown in fig. 1-3, before slag discharging, a base 5 is welded at the bottom of a tundish car 7, an overflow tank is arranged on the base 5, a tundish slag flowing port 6 is arranged below the overflow tank, dry slag 3 is laid in the overflow tank, a hanging ring 4 is placed in the overflow tank, liquid steel slag discharged by the tundish flows into the overflow tank from the tundish slag flowing port 6, after the liquid steel slag, the hanging ring 4 and a small part of the dry slag 3 are solidified into a whole, the hanging ring 4 is hung by using an external hoisting device when the ladles are alternated, the steel slag is hoisted away, a new hanging ring 4 is placed into the overflow tank before next slag discharging, after the dry slag 3 in the overflow tank is reduced to a certain thickness after the liquid steel slag, a hanging lug 2 is hoisted by using the external hoisting device when the ladles are alternated, the overflow tank is hoisted out, and the overflow tank is hoisted back to the original position after the overflow tank is filled with a sufficient amount of the dry slag 3, and then a new hanging ring 4 is placed into the overflow tank.
