|RIFCO has designed more than 100 different pre-cast/pre-fired refractory shapes for use in a number of vulnerable refractory lined areas of industrial furnaces. The advantage of pre-cast/pre-fired shapes is that a skilled bricklayer is not required for installation (often they are just set or bolted in place) and the furnace can be put into service immediately after installation. NO bake-out period required.|
This feature offers easily replaceable wall blocks that provide protection from impact for the ceramic fiber wall insulation. We have shapes that we fire burners though for applications requiring burners to be fired below the workload. We continually incorporate this design with our “Push-In”™ style furnace to car seal described above.
We often design pre-cast shapes for door jambs and lentils. These designs often provide for thicker sections than the wall or roof linings behind them to provide an adequate “return” dimension resulting in a smaller window for an operator to aim for when loading the furnace which eliminates impact damage to the wall and roof linings. The pre-cast refractory is suitable for impact and abrasion resistance which often holds up well to mal-adjusted product when loading the furnace.
Often, it is desirable to use pre-cast refractory shapes as workload piers or in conjunction with alloy workload support piers to raise the the furnace load above the refractory hearth of both car bottom or box type furnaces. This design is used to elevate the load off the hearth for temperature uniformity issues, as well as, for firing burners under the workload.
