Abstract

An edge wrapping structure for preventing brick from falling and enlarging gap of brick belongs to the steel pack technical field of steel-making device, which provides a structure that a hinder plate can not be propped up when the wrapping wall brick occurs heat dilation, and the hinder plate and the most upper layers wrapping wall bricks can not be scraped by the scraping wrapping edge stained slag steel, and preventing wrapping brick from falling and enlarging gap of brick, which comprises a wrapping shell, a wrapping wall brick on the inner shell wall, a hinder plate on the wrapping opening and a wrapping edge brick material, a hinder oblique arrangement, the wrapping edge brick material is filled between an oblique outer plate face and a wrapping opening, and a fire endurable material pouring is filled between an oblique inner plate face and the wrapping wall brick, and a fixation plate is added between the oblique outer plate face and the inner shell wall. The action force on the oblique inner plate face is reduced when the wrapping wall brick going throw heat dilation. Simultaneously, the connection between the oblique hinder plate and the wrapping shell is more fixed, which avoid effectively the bending and scraping of hinder plate and erosion of edge wrapping, falling of wrapping brick when scraping of with a reliable work, long cycle time, reduction of repair and reduction of utilization cost.

Description

The bag that the anti-brickwork joint of anti-lost brick increases is along structure

Technical field

The utility model relates to the bag at ladle, especially ladle mouth place in the STEELMAKING PRODUCTION along structure, belongs to ladle facility technology field.

Background technology

The bag of existing ladle is a general horizontal baffle version shown in Figure 2 along structure, and horizontal baffle 7 is perpendicular to the involucrum shell wall, its with inner wall on bag nogging 4 between fill and wrap along brick material 3.During this kind bag uses along structure, horizontal baffle can be bent, push away because of the thermal expansion of bag nogging, when bag scrape after be stained with slag, steel bag along the time also be easy to be wiped off, wipe of the brickwork joint increase of the bag of the unobstructed exposure portion in back off along brick material 3, the position that brickwork joint is big in the use eats away earlier, shorten the service life of the anti-material of ladle, influenced the normal life cycle of ladle; Simultaneously, the back is unobstructed because horizontal baffle 7 comes off, and can together be with which floor bag nogging 4 of top when striking off cinder and steel sticking more later on, has influence on the Sheng molten steel amount of ladle.For this reason, must improve along structure existing horizontal baffle formula bag.

Summary of the invention

Technical problem to be solved in the utility model provides the bag of the anti-brickwork joint increase of a kind of anti-lost brick along structure, to solve the use defective of above-mentioned horizontal baffle bag along structure.

The alleged problem of the utility model realizes with following technical scheme:

The bag that the anti-brickwork joint of a kind of anti-lost brick increases is along structure, bag nogging 4 on involucrum 1, the inner wall, the baffle plate that wraps the mouth place and bag are arranged along the brick material in the formation, its improvement is, described baffle plate 2 is obliquely installed, described bag is filled between inclination outer plate surface and the bag mouth along brick material 3, filling fire resisting material casting matrix 6 between inclination inner plate surface and the bag nogging 4 is set up gusset plate 5 between inclination outer plate surface and the inner wall.

Above-mentioned anti-lost brick is prevented the bag of brickwork joint increase along structure, described bag nogging 4, and its relative position with the inclination inner plate surface is the inclined plane.

The bag that the anti-brickwork joint of above-mentioned anti-lost brick increases is along structure, and the inclination angle a of described baffle plate 2 is 30 °～60 °.

After adopting the utility model design, on the one hand, the active force that acts on the inclination inner plate surface during thermal expansion of bag nogging significantly reduces, and on the other hand, the connection between sloping baffle and the involucrum is more firm, so can effectively eliminate baffle plate is bent, pushes away, wipes off, bag wraps use defectives such as nogging easily comes off along being etched, scraping when wrapping, and has realized goal of the invention of the present utility model, also has simple in structure simultaneously, easy to implement, be convenient to the characteristics that on existing ladle, adopt.Adopt ladle working of the present utility model reliable, use turnover period long, can greatly reduce and repair baffle plate, bag, reduce the use cost of ladle along workload.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is that existing bag is along structural representation.

The parts label is in the accompanying drawing: the 1-involucrum, and the 2-baffle plate, 3-wraps along the brick material, and 4-wraps nogging, 5-gusset plate, 6-refractory material casting matrix, 7-horizontal baffle.

The specific embodiment

Consult accompanying drawing 2.The inclination angle a of baffle plate 2 is 45 ° in the utility model, and the quantity of gusset plate 5 is greater than 2, and is uniform along the inner wall of involucrum, and welded connection between the inclination outer plate surface of sloping baffle 2 and the inner wall.Bag is filled along brick material 3 along the cavity between inclination outer plate surface and the inner wall, and gusset plate 5 is imbedded in the obturator.Then fill fire resistance between inclination inner plate surface and the adjacent upper layer packets nogging 4 and water material feeding body 6, the position of bag nogging 4 corresponding tilt inner plate surfaces is corresponding to cut into corresponding inclined plane, to make things convenient for filling fire resisting material casting matrix 6 and to form the uniform cast layer of thin and thick.
