Description

A kind of refractory ceramic pedestal

Technical field

The present invention relates to the containers for handling high-temperature fusant, and in particular to a kind of refractory ceramic pedestal.

Background technique

First there is refractory ceramic pedestal to simplify very much, generally comprise a pedestal and a wall moved up from pedestal, The inside is mainly circular internal cross section, and a hole is at least disposed with material is thus formed the pot-shaped of an entirety, in pedestal (region of discharge), the metal bath handled in ceramics enter downstream unit, such as tundish by discharge (faucet).For gold Belong to adjusting/control of melt amount, such as has retainer or sliding plate valve, also referred to as control device.If pomace also enters tundish, The quality of steel reduces and the durability of tundish.Therefore, it once slag reaches discharge outlet, attempts to close discharge outlet immediately, Then ceramics are toppled over the slag of surplus and steel slag, therefore, the heavy losses of material and high-cost recycling occur.Due to furnace Gently, so mainly floating on metal bath, therefore, the surface of base of ceramic is designed to inclined to slag ratio metal bath (steel melt) Mode, so that as much as possible before clinker flows through, liquid metal as much as possible is transported to by the way that leading (opening) is discharged Bottom, this needs corresponding complicated base shape, and the fire prevention lining of pedestal is complex and costly.

Technical solution

The invention mainly solves the technical problem of providing a kind of refractory ceramic pedestals, at least one wall with container In join domain, for handling high-temperature fusant, it is characterised in that: refractory ceramic substrate has at least two layers, i.e., by refractory Manufactured lower layer in permanent liner is wherein the prefabricated elements made of at least one whole fire blocks in permanent liner, so that permanently Lining further includes mainly the upper layer made of refractory wear resistance lining, wherein in permanent liner by least one whole fire blocks With the surface adjacent with abrasion lining, compared with horizontal plane, the surface tilts at least 2 ° -25 °, and the surface has three-dimensional Design, wear resistance lining are made of the refractory solid brick of at least 60M%, and wherein at least 60% solid brick of wear resistance lining is Identical, wherein at least 70% solid brick has rectangle or polygonal profile in a top view, and wherein at least The solid brick of 75% wear resistance lining is laid single layer, and in permanent liner and wear resistance lining has at least one inconsistency, uses In integrating at least one common discharge mouth for high-temperature fusant.

Optionally, the pedestal also has at least one individual element, be built in permanent liner and wear resistance lining in.

Optionally, wherein the solid brick of wear resistance lining be at least partly arranged to be made of multiple solid bricks it is pre-assembled Section

The beneficial effects of the present invention are:

A kind of refractory ceramic pedestal of the invention, fusing as much as possible can be from melt container with good in this configuration Good quality removal.

Embodiment

The preferred embodiments of the present invention will be described in detail below so that advantages and features of the invention can be easier to by It will be appreciated by those skilled in the art that so as to make a clearer definition of the protection scope of the present invention.

Fig. 1 shows the substrate with two layers, i.e. lower layer 10 and the upper layer 20 for being arranged in top, and the two is in top (plane) All be in view it is approximate circle, lower layer 10 is designed as in permanent liner, and is made of the refractory ceramic block based on aluminium oxide, forever Long lining 10 is designed as prefabricated elements and the upper surface with horizontal surface 10u and three dimensional design completely, and has following Region: about in the first step 13 at center, the impact pad 14 of the protrusion of upper left one third, all areas on surface 100 are opposite About 3 ° are tilted in horizontal direction, and is tilted towards the direction of discharge areas 30；Upper layer 20, i.e. wearing layer, mainly (80~ M% cube refractory brick 21) is in identical layout, and other than the area of electric discharge 30, size is identical, therefore, wearing layer The geometry of 20 downside 20U and upside 20O generally follow the geometrical condition of in permanent liner 10 upside 10O；Brick 21 is (real Heart brick) it is slightly offset in the region on step 13 (slope: about 90 °), as shown in Fig. 2, upper in resulting permanent liner Space 23 between side 10O and the downside 20U of brick 21.1 is filled in the fire resisting mass on aluminium oxide base portion, this is for similar slope (Fig. 4) is that similar have for 25 ° of regions (Fig. 3) or the step of positioning solid brick 21 on the continuous tilt surface of Different Slope Effect.Fig. 5 shows one embodiment, wherein the plane inclined surface of figure, replaced by stepped profile, however, technically complete The slope similar with Fig. 3 is created entirely, in fact, term " inclined surface " technically also includes with corresponding continuous small The embodiment of step 13 (Fig. 5).As a shown in Figure 6, also have between the chamber wall 52 of the adjacent flex of brick 21 and ceramics 50 convex Z is played, these regions have also filled up the fire blocks of an entirety, and on the basis of the present invention, only lining 20 is worn in replacement, in order to do To this point, the brick 21 and possible other elements for wearing lining 20 are removed, and 10 remain unchanged in permanent liner.Therefore, newly Abrasion lining 20 be reestablished in permanent liner 10 it is existing geometrically so that the upside 200 of wear resistance lining 20 is again Corresponding in permanent liner 10 morphology.

The sequencing of above embodiments is not only for ease of description, represent the advantages or disadvantages of the embodiments.

Finally, it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although Present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: it still may be used To modify the technical solutions described in the foregoing embodiments or equivalent replacement of some of the technical features； And these are modified or replaceed, technical solution of various embodiments of the present invention that it does not separate the essence of the corresponding technical solution spirit and Range.
