    Refractory Cordierite Kiln Posts High Temperature Resisitance 265 * 60 * 60mm


    Refractory high temperature Cordierite kiln post 265*60*60mm


    1. Description

    The refractory product is composed of high uality mullite and high purity fused cordierite as raw materials with addition of specified binder by shaping at high pressure and sintering at high temperature. With features of high refractoriness under load, compact structure, low porosity and high resistance to corrosion. High strength,high thermal shock resistance,heat-resistant and low heat conduction.

    A simple firing to 1300C (about cone 11 and within the reach of many ordinary kilns) and soaked may produce some crystal development. However firing (actually sintering) at 1400C+ with significant soaking time is needed for the best results. Thermal expansion measuring equipment is needed to determine if your firing is actually developing the crystal matrix or not.
    As noted, a continuous crystal matrix is the object of cordierite creation (not just the presence of the crystals in an otherwise typical ceramic). Notwithstanding this, cordierite powder is available, it is prefired and finely ground. It can be plasticized for forming and bonded during firing (at much lower than normal cordierite creation temperatures) to produce a ceramic that certainly has lower expansion.

    3. Advantages of Cordierite

    A. Weight reduction of approximately 35% - 50%, whilst increasing the load capacity of the batt. For example, a 38mm-thick extruded batt has the same weight as a 23mm-thick pressed batt of the same size, but can bear 5 times the load.
    B. Energy Savings. Tests have shown that using extruded batts in a shuttle kiln firing glass panels, fuel consumption can be reduced by between 30% and 70%.
    C. Reduced bend at high temperatures. 1200mm long extruded batts supported by silicon carbide beams have shown virtually no bend during use. This is extremely useful where flatness is critical, such as in the firing of glass panels.
    D.Their ability to disperse heat is twice that of a solid batt of similar size, allowing them to bear extremes of hot and cold much better, thereby increasing their service life. This makes extruded batts especially suitable for faster firings.
