Description
Technical field
The utility model relates to the insulation can for fused cast zirconia-alumina brick, particularly a kind of insulation can preventing Corhart Zac-block thermal crack.
Background technology
Zirconia-corundum refractory brick is mainly used in glass furnace, and current glass industry production capacity surplus, enterprise operation is difficult.The upgrading of glass quality, the increase of glass kind and the superseded high operation mode consuming low energy are only the current road based oneself upon of glass enterprise.The upgrading of glass enterprise has the strict demand of quality to zirconia-corundum refractory brick, the quality defect of zirconia-corundum refractory brick directly can affect the quality of glasswork, also affects the work-ing life of glass furnace.Whether the crackle that the presentation quality of zirconia-corundum refractory brick typically refers to goods exceeds use standard, (other presentation quality also has the color, pore etc. of product surface).And thermal crack is common defect.
Thermal crack qualitative: when the annealing process after zirconia-corundum refractory brick casting is too fast, at temperature, degree is down to the cold crack that less than 1140 DEG C will produce goods.More than the 1140 DEG C crackles formed are thermal crack.The reason that thermal crack is formed: time liquid, fused cast refractories can not form thermal crack, and the conversion process only when liquid conversion is solid forms thermal crack, after fused cast refractories casting, the initial set temperature of temperature-fall period is about 1600 DEG C.It is the temperature range that thermal crack produces 1200 DEG C to 1600 DEG C time.Thermal crack Producing reason be first expand with heat and contract with cold caused by, rib position, the angle heat storage capacity as goods is few, cools in advance, and namely shrink very fast, goods middle part heat storage capacity is large, and shrink comparatively slow, the rib position, angle of shrinking in advance will produce across rib crackle; Second be during the temperature of 1200 DEG C to 1600 DEG C, goods are given a shock, clash into formation mechanical crackle; Three is high-temperature factors of goods casting, make it surrounding lagging material soften aggravation goods action of gravity under sinking factor, make goods the temperature range internal strain of 1200 DEG C to 1600 DEG C, cause crackle.Brick normal rates is gross production that what thermal crack caused scrap 10 three to percent about 15, the thermal crack ratio of scrapping caused because of sinking factor has about 10, thermal crack is that zirconia-corundum refractory brick scraps a maximum link of ratio, also be maximum waste root. the sinking factor without shrinkage cavity pool wall is: there is the space that much sinks, these sinking spaces are exactly the Crack cause .1 of thermal crack, without first will sand mold mould be placed in insulation can before the casting of shrinkage cavity brick, (insulation can is made up of lower box and extending sleeve insulation can, extending sleeve regulates insulation can function of height, mould exceeds insulation can will use extending sleeve, extending sleeve can add according to the height of brick .) fill insulation sand, shaken by vibration shape platform, insulation sand and sand mold are combined closely, place the condition of high temperature after casting and action of gravity causes brick to rise modification, because rising head volume is greater than brick body after casting, in sinking watching, brick body easily sinks, and rising head greatly not easily sinks due to volume, cause brick body sinking rising head not sink to defining because of the thermal crack that causes of sinking.2, in order to make brick bottom thermal insulation layer have enough thickness to reach heat insulation effect, at the bottom of frame, upper berth is lined with insulating brick, the place mat of insulating brick lays out one by one, will not spread some fine sands at ordinary times and come levelling, just creates the sinking space under the rear action of gravity of casting during this.The above-mentioned thermal crack factor being the space sunk owing to having the rear goods of casting in insulation can and causing.Therefore, the improvement and bring new ideas of insulation can is imperative.
Summary of the invention
For above-mentioned situation, for overcoming the defect of prior art, the object of the utility model is just to provide a kind of insulation can preventing Corhart Zac-block thermal crack, effectively can solve the problem of Corhart Zac-block thermal crack.
The technical scheme that the utility model solves is, a kind of insulation can preventing Corhart Zac-block thermal crack, comprise casing, casing is by lower box and the hollow structure being contained in the upper opening that the extending sleeve on lower box is formed, sand mold mould is contained in casing, be provided with main body lagging material between the outer wall of sand mold mould and the inwall of casing, in the base of lower box, be provided with the mezzanine space of opposing seal, in mezzanine space, be filled with bottom lagging material.
The utility model novel structure is unique, and advantages of simple, easily produces, and cost is low, effectively reduces the thermal crack of Corhart Zac-block, easy to use, effective, is the innovation on insulation can.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Provided by Fig. 1-4, the utility model comprises casing, casing is by lower box 4 and the hollow structure being contained in the upper opening that the extending sleeve 5 on lower box is formed, sand mold mould is contained in casing, main body lagging material 3 is provided with between the outer wall of sand mold mould and the inwall of casing, be provided with the mezzanine space of opposing seal in the base 11 of lower box 4, in mezzanine space, be filled with bottom lagging material 12.
For ensureing result of use, the sidewall of described extending sleeve 5 lower end is provided with fixing along 9, the sidewall of the upper end of lower box 4 is provided with fixing along corresponding lower fixing along 10 with upper, two is fixing along being above provided with corresponding fixed orifices 14, extending sleeve 5 and lower box 4 are bolted together by the standing bolt about 8 be installed in fixed orifices, form reassembling type structure;
Described extending sleeve 5 is the square frame-shaped structures of the upper and lower opening formed of being joined end to end by 4 pieces of side plate 5a, the L-shaped corner web plate 7 in cross section is equipped with in the junction of two biside plates, corner web plate is provided with at least 2 row adjustment holes 15, the both sides of side plate are provided with the pilot hole 13 corresponding with adjustment hole, side plate and corner web plate are fixed together by the tack bolt 6 be installed in pilot hole and adjustment hole, form the broad-adjustable reassembling type structure of extending sleeve;
Described adjustment hole 15 has and has 2 row at least, often row include vertically uniform multiple, upper fixing edge and fixingly all have 2 row at least and columns is equal with the columns of adjustment hole along upper fixed orifices down, fixed orifices row and the spacing arranged and adjustment hole arrange equal with the spacing arranged, and spacing is 20mm;
Described sand mold mould is the integrative-structure of the upper opening be made up of with the rising head sand mold 1 being contained in brick body sand mold upper oral part brick body sand mold 2, and rising head sand mold is placed in the scope at extending sleeve 5 place;
