Description

The combined type saggar

Technical field

The utility model relates to mechanical, particularly a kind of combined type saggar.

Background technology

As accompanying drawing 1 to shown in the accompanying drawing 4, general integrally formed saggar A commonly used is made of front side board A1, back side panel A2, left plate A3, right plate A4 and glove plate A5, when saggar A carries out high-temperature heat treatment by incinerator, because general heat treatment has a plurality of temperature sections, so that make saggar A in heat treatment process is quickened, easily because of the temperature spread between temperature section is big, and makes saggar A be heated inhomogeneous and cause surface expansion to change, and then cause saggar A moment to produce the situation of breaking; In addition, also has a kind of combined type saggar B, because combined type saggar B often adopts the multiple-level stack mode to carry out sintering, and this combined type saggar B goes up for fixing preceding width fixed head B1, in the process of carrying out high-temperature heat treatment, have to cause the worry that comes off, rupture and block stove, and then cause producing have some setbacks and finished product in the surge of defective products, and then thing B2 production cost to be sintered is improved, need be improved.

The utility model content

The purpose of this utility model is to provide a kind of combined type saggar, has solved existing saggar and has easily produced surface expansion and change and then cause saggar moment to be broken, production cost height, problem such as defective products is many.

The technical solution of the utility model is: comprise left side brackets bar, right side support bar, saggar base plate and a plural number carrier strip, wherein, this plural number props up carrier strip and left side brackets bar, and the tight symmetrical coaptation splint of support bar hole, right side forms the steel body of combined type saggar, owing to put the saggar base plate on the plural number carrier strip, the side that this saggar base plate extends in the plane is provided with the vertical surface that one is bent to form;

When putting thing to be sintered in the saggar base plate, see through the vertical surface that saggar base plate one is bent to form, and the vertical surface of a plural number carrier strip two side ends support bar, can avoid thing to be sintered when heat treatment process, the situation that produces thing landing to be sintered and topple over, and should plural number prop up the steel body that carrier strip forms the combined type saggar, and can bear heating and cooling rapidly and change, and the unlikely combined type saggar that makes produces the situation that moment breaks;

On left side brackets bar and the right side support bar, be provided with the fixing hole of a salient point and center below in the top of center, when the combined type saggar carries out the multiple-level stack arrangement, on left side brackets bar and right side support bar, the salient point that parallel symmetry is extended, and the fixing fixing hole of Stackable, then can make the combined type saggar when stacked arrangement is used, avoid the combined type saggar to produce landing and the situation of toppling over.

Advantage of the present utility model is: the rate variation of rapid heating and cooling between the withstand temperature section; Change the line expansion into by the surface expansion variation when being heated inequality and change, than heat shock resistance; Produce in the time of can avoiding piling up saggar and topple over, can avoid sinter to produce landing; Can effectively improve the quality of thing to be sintered, and effectively reduce production cost, practical.

The specific embodiment:

As accompanying drawing 5 to shown in the accompanying drawing 8, the utility model comprises left side brackets bar C, right side support bar D, saggar base plate E and the plural number formed combined type saggar of a carrier strip F G, this plural number props up carrier strip F and left side brackets bar C, and right side support bar D, after tight symmetry engages folder hole C1, D1, then form the steel body G1 of combined type saggar G, owing to can put saggar base plate E on the plural number carrier strip F, and last after putting thing H to be sintered as saggar base plate E, then can carry out the process of high-temperature heat treatment:

When putting thing H to be sintered in the saggar base plate E, see through the vertical surface E1 that saggar base plate E one is bent to form, and vertical surface C2, the D2 of plural number carrier strip F two side ends support bar C, D, can avoid thing H to be sintered when heat treatment process, the situation that produces thing H to be sintered landing and topple over, and should plural number prop up the steel body G1 that carrier strip F forms combined type saggar G, and can bear heating and cooling rapidly and change, and the unlikely combined type saggar G that makes produces the situation that moment breaks; And this combined type saggar G and saggar base plate E are made by refractory material such as aluminium oxide, zirconia, carbonization silicon, and the linear expansion coefficient of refractory materials such as this aluminium oxide, zirconia, carbonization silicon is 3 * 10 ^-6To 9 * 10 ^-6, when heat treated temperature when rising or descend, this refractory material then can present to expand and becomes big and shrink the variation that diminishes;

This plural number props up carrier strip F when bearing temperature changes, because the length variations that thermograde produces, make a plural number carrier strip F can produce the microbend distortion, make this combined type saggar G in heat treatment process, can bear bigger thermal shock and do not break, wherein this saggar base plate E sees through the vertical surface E1 that one is bent to form, and vertical surface C2, the D2 of plural number carrier strip F two side ends support bar C, D, can effectively avoid placing the thing H to be sintered of saggar base plate E top, in carrying out high-temperature heat treatment process, the situation that produces thing H to be sintered landing and topple over;

On left side brackets bar C and the right side support bar D, be provided with fixing hole C4, the D4 of a salient point C3, D3 and center below in the top of center, when combined type saggar G carries out the multiple-level stack arrangement, on left side brackets bar C and right side support bar D, salient point C3, D3 that parallel symmetry is extended, and fixing fixing hole C4, the D4 of Stackable, then can make combined type saggar G when stacked arrangement is used, avoid combined type saggar G to produce landing and the situation of toppling over.

Shown in accompanying drawing 9 and accompanying drawing 10, the vertical surface E1 that saggar base plate E goes up the one bending can be set to the two sides vertical surface of one bending, three vertical surfaces, four sides vertical surface, so that combined type saggar G in heat treatment process, can effectively prevent thing H to be sintered landing;

The vertical surface E1 that this saggar base plate E one is bent to form also can be set to split type base plate plane E2, and the saggar side plate E3 of vertical surface, and the base plate plane E2 that this is split type, and saggar side plate E3 further again can be by the fixing mode of bonding, clamping, engaging and associated splice, make saggar base plate E can cooperate the steel body G1 of various combination formula saggar G, and then make between saggar base plate E and combined type saggar G, can reach good fixing and prevent thing H to be sintered landing.
