A kind of device of making fused alumina zirconia hanging screen brick casting die
Technical field:
The utility model belongs to glass furnace refractory material cast molding technical field, mainly proposes a kind of device of making fused alumina zirconia hanging screen brick casting die.
Background technology:
For reducing of the influence of melting end thermal-flame to cooling end, to guarantee separately independently operation system, need set up separating device at flame space intersection (card neck), be generally gable or hanging screen.Used refractory material adopts sintering silica brick, fused mullite brick, vitreous silica etc. more, and the anti-kiln furnace gas of these materials coagulation erosion performance is relatively poor, often forms stalactitic corrode thing curtain, forms foreign material in the drippage glass; Thermal shock resistance is also poor, splits easily, is out of shape.Up-to-date employing casting fused alumina zirconia material, the casting die that need adapt with it.
Summary of the invention:
The purpose of this utility model promptly is to propose a kind of device of making fused alumina zirconia hanging screen brick casting die.
The technical scheme that its invention task of finishing the utility model is adopted is:
A kind of device of making fused alumina zirconia hanging screen brick casting die, described device comprises a metal outer frame, metal outer frame two parts for being provided with respectively along the diagonal angle; Two parts that described metal outer frame is provided with respectively design outwardly directed eaves by connecting and composing an integral body at two-part connecting portion, and adopt geometrical clamp fastening; Described device has a wooden model, and described wooden model is and the identical wooden entity of fused alumina zirconia hanging screen brick shape to comprise wedge shape hook and bottom rectangular body that top is wide at the top and narrow at the bottom; Described metal outer frame is surrounded around wooden model, has the gap between metal outer frame and the wooden model, shape, the consistent size of gap between described metal outer frame and the wooden model and made casting die.
The utility model is used to make the casting die of fused alumina zirconia hanging screen brick, has characteristics simple in structure, easy and simple to handle, easy making.
Description of drawings:
Accompanying drawing 1 is a structure chart of the present utility model.
Among the figure: 1,4, geometrical clamp, 2, metal outer frame, 3, sand mo(u)ld, 5, wooden model.
The specific embodiment:
The embodiment that provides in conjunction with the accompanying drawings is illustrated the utility model:
As shown in Figure 1, a kind of device of making fused alumina zirconia hanging screen brick casting die comprises a metal outer frame 2, metal outer frame two parts for being provided with respectively along the diagonal angle; Two parts that described metal outer frame 2 is provided with respectively design outwardly directed eaves by connecting and composing an integral body at two-part connecting portion, and adopt geometrical clamp 1 and 4 fastening; Have a wooden model 5, described wooden model 5 is and the identical wooden entity of fused alumina zirconia hanging screen brick shape to comprise wedge shape hook and bottom rectangular body that top is wide at the top and narrow at the bottom; The processing that wooden model has a 3mm high-volume, promptly the appearance and size of wooden model is than the big 3mm of appearance and size of the hanging screen brick of producing; Described metal outer frame 2 is surrounded around wooden model 5, has the gap of 45mm between metal outer frame 2 and the wooden model 5, tamps the gap with quartz sand and adhesive, is solidified as casting sand mo(u)ld 3.
