Detailed description of the invention
Embodiment one
A kind of Novel sagger, forms the cavity for roasting including bottom surface and sidewall, described bottom surface and sidewall, and described Novel sagger includes matrix and working lining, and described working lining is on matrix work surface；The composition of described matrix is: mullite 35wt%, corundum 15wt%, Kaolin 14wt%, alumina powder 14wt%, quartz 14wt%, cordierite 8wt%；The composition of described working lining is: potash feldspar 13wt%, vitreous silica 15wt%, mullite 15wt%, andalusite 13wt%, corundum 10wt%, alumina powder 12wt%, zirconia powder 10wt%, Talcum 5wt%, calcining magnesia 7wt%。The granularity of described cordierite, zirconium oxide and mullite is not more than 200 orders；Described alumina powder particle diameter is not more than 2mm；The thickness proportion of described matrix and described working lining is 7:3；Described matrix first forms suspension with Kaolin, described suspension adds all the other raw materials of matrix, is so possible to prevent Kaolin not to be able to do in time to melt completely so that during the saggar molding prepared, fully do not obtain plasticity。Meanwhile, Kaolin clay suspension adds alumina powder and Kaolin can be played enhancement abrasive action, Kaolin in this way can be made uniformly to configure, it is also possible to make stock obtain the mullite phase of maximum level。Andalusite in working lining adopts raw material andalusite, when adopting calcining andalusite, the mullite skeleton that the calcining raw materials stage is formed is subject to heavy damage when pulverizing, making mullite network in manufactured goods be difficult to be formed, and adopt raw material andalusite, mullitization process carries out when firing finished product, manufactured goods can be formed complete mullitization network, thus improving the refractoriness under load of goods, simultaneously in order to make andalusite have better agglutinating property, adopt wet-milling broken andalusite；The working lining of Novel sagger adds zirconia powder, substantially increases the thermal shock resistance of Novel sagger, improve the service life of Novel sagger；Simultaneously because the use temperature of Novel sagger is between 900～1000 DEG C, refractoriness is less demanding, but repeatedly to work in high temperature and normal temperature environment, thermal stability requirement is higher, though the addition of Talcum and calcining magnesia makes the refractoriness of Novel sagger slightly reduce, but not affecting the use of Novel sagger on the one hand, the thermal shock resistance that can make Novel sagger on the other hand is better, longer service life；At high temperature melting viscosity is high except self for potash feldspar in working lining, possess outside the effect that high temperature is cementing, it is also possible to react with corundum etc. define new material, the adhesion of the novel substance formed is bigger than the high temperature cementation adhesion of simple potash feldspar, the adhesion between matrix and working lining can be effectively improved, simultaneously can also be effectively improved the adhesion between each composition of working lining, make Novel sagger entirety be firmly combined with, be conducive to improving Novel sagger service life；Owing to the operating temperature of Novel sagger provided by the invention is 900～1000 DEG C, and potash feldspar fusing point is within the scope of 1150 ± 20 DEG C, such that it is able to avoid causing that adhesion reduces because potash feldspar is melted in Novel sagger；Sintering temperature also can be greatly lowered, thus reducing production cost after adding potash feldspar；Potash feldspar can also accelerate mullite and form speed, to improve the refractoriness under load of Novel sagger。
Although potash feldspar has plurality of advantages, but in use finds through test of many times: potash feldspar content, lower than 5wt%, very easily occurs in conjunction with hypodynamic problem, cause that working lining departs from matrix；Potash feldspar content is higher than when 20wt%, and working lining vitreous phenomenon is serious, and resistance to heat shocks is not enough, it is easy to break；Potash feldspar content is above-mentioned when 10wt%～15wt% to be greatly improved in conjunction with hypodynamic problem and working lining vitreous phenomenon serious problems；Especially potash feldspar content is when 13wt%～14wt%, it is possible to takes into account adhesion problem and working lining vitreous problem simultaneously, makes both to obtain optimum efficiency。
The matrix of described Novel sagger and each raw material of working lining mix by proportioning respectively and stir 30min respectively in blender；The matrix of described Novel sagger is compressing with dry method, and briquetting pressure is 45MPa, and working lining raw material after mixing is uniformly sprinkling upon on matrix work surface and is pressed on matrix work surface by working lining raw material with the pressure of 60MPa；Sintering temperature is 1300 DEG C, and sintering time is 2 hours, then Temperature fall, prepares Novel sagger。Mixing time selects 30min to take into account the uniformity of cost and material, it is ensured that the Forming Quality of Novel sagger and mechanical strength；Working lining selects to be pressed on matrix with the pressure of 60MPa, is because finding in the fabrication process, easily causes working lining and be combined loosely with matrix when pressure is less than 60MPa, easily makes matrix deform, also can cause the waste of resource when pressure is more than 60MPa；Sintering time selects to have taken into account for 2 hours the quality of cost and Novel sagger, it is ensured that product is mullitization as far as possible。
