Abstract
The utility model relates to an improved sagger of refractory kiln furniture; The utility model is characterized in that the open mouthed sagger is formed by adjacently combining and joggling four pieces of sagger walls and one piece of sagger bottom sintering fireproof plate, each edge of the sintering fireproof plate has at least one stress groove which extends inwards and is circular arc-shaped at the end, and the adjacent combined edge has a splicing joggle concave and / or a joint tongue. The depth of the sagger can be designed at random according to the requirement, the volume of the sagger is sharply increased, the stress groove which extends inwards and is circular arc-shaped at the end is arranged on the edge of the sintering fireproof plate, thereby effectively neutralizing the stress cracking because of heat expansion and cold contract, and improving the service life of the sagger. The combination entirety of the joggle type splicing, in particular the swallowtail splicing is good, and uneasy to spread out.
Description
Technical field
Utility model is about to fire-resistant kiln furnitures---the improvement of saggar relates in particular to the fire-resistant saggar of a kind of big combined capacity formula.
Background technology
Ceramic, fire-resistant industry is held firing tool---saggar, usually adopts compacting, molded uncovered rectangle or rectangle, and overall structures such as circle, ellipse, promptly by refractory material repressed or molded and shaped after, form through sintering.The deficiency of this overall structure saggar is, owing to be subjected to make restriction, the saggar degree of depth is more shallow, generally be difficult to surpass 15cm, thereby the volume of saggar is less relatively, strengthens the saggar sectional dimension, though the saggar volume is increased, but the damage in use more easy to crack of excessive saggar, and be subjected to the restriction in kiln cross section, saggar reality can not do very greatly; Secondly, whole compacting saggar, saggar coaming plate and base plate be because of lacking the buffering seam that expands, and expands, shrinkage cracking damages shortening saggar service life in using repeatedly easily.This two big defective fails effectively to be solved for a long time.
The utility model content
The utility model purpose is to overcome the deficiency of above-mentioned prior art, and a kind of saggar degree of depth that strengthens is provided, and obtains big volume, and the saggar fire-resistant saggar of damage easy to crack not.
The utility model purpose realizes that main the improvement is with compacting or the whole saggar of molded sintering, changes the built-up container body of forming by around the fire-resistant thin plate amalgamation of knot into, thereby overcomes the deficiencies in the prior art, realizes the utility model purpose.Specifically, the fire-resistant saggar of utility model, comprise that quadrangle forms uncovered saggar, it is characterized in that sintering refractory slab at the bottom of uncovered saggar is by 4 cassette walls and 1 cassette, lead joggle to combine mutually, each limit of sintering refractory slab have at least one extend internally, end is not the stress groove of circular arc, there is the recessed and/or joint tongue of grafting tenon on adjacent combination limit.
The said sintering refractory slab of utility model, by being fit to for example SiC of refractory material that serviceability temperature requires, compacting, sintering form, and its thickness is in the 9-20mm scope.
Said stress groove, main effect are to prevent refractory slab expansion cracking and be provided with, and its length is generally 40-80mm, wide 2-3mm, and the big slightly circular arc of end has not more increased anti-cracking performance.
Leading tenon to close grafting mutually, then mainly is to take measures for strengthening combinative stability, and it can be that flat tenon is pegged graft, but a kind of dovetail tongue-and-groove that more preferably adopts pegs graft, and its anti-performance of scattering is better.The adjacent side is provided with the recessed and/or joint tongue of tenon, can be that an edge is provided with the recessed and joint tongue of tenon simultaneously, also can be the recessed adjacent setting with joint tongue of tenon.
The fire-resistant saggar of utility model split-mounting type, sintering refractory slab assembled structure, overcome prior art compacting or molded and shaped after the whole saggar deficiency of knot of reburning, can design the saggar degree of depth as required arbitrarily, the saggar volume is increased greatly, and sintered plate amalgamation, the stress groove that extends internally can be set on the sintering edges of boards, and groove do not held be designed to circular arc, thereby effectively offset the stress cracking that expands with heat and contract with cold, greatly reduce the saggar use and be subjected to the variations in temperature stress cracking, greatly improve built-up container body and in high temperature, used distortion, and high-temperature machinery intensity, resistance to sudden heating is good, and the resistance ability is strong, and the rate variation of rapid heating and cooling between energy bearing temperature section, the service life of having improved saggar.The tenon formula is pegged graft, and especially dovetail is pegged graft, and composite entity is good, is difficult for scattering, and produces in the time of can avoiding piling up saggar and topples over.
Below in conjunction with two optimization specific embodiment, further specify utility model, but embodiment can not be interpreted as to concrete qualification of utility model and constraint.

Fig. 2 is a utility model embodiment saggar sintering wallboard schematic diagram.
Fig. 3 is a utility model embodiment joggle built-up container body schematic diagram.
The specific embodiment
Embodiment 1: referring to accompanying drawing, the fire-resistant saggar of utility model combining structure, comprising that 1 block of sintering is thick is the SiC base plate 1 of 10mm and 4 wallboards 2, each sintered plate periphery has at least one to extend internally and be about 50mm, wide about 2mm stress groove 5, it does not hold the circular arc 6 of diameter greater than groove width, the adjacent fillet of sintered plate has dovetail recessed 3 and/or dovetail joint tongue 4, the sintered plate tenon is plugged together 7 splicings form uncovered saggar.
Embodiment 2: as embodiment 1, behind the composition saggar, embed high temperature resistant filler inorganic clay in each stress groove, be used for sintering powder, powder is scattered from the stress groove, effective again proof stress groove function.
In addition, can also adopt straight tenon to peg graft and make up, or other shape tenons grafting combinations.
