Hollow Setter Plate BATTs
1. Classification of BATTS
(1) Plain Batts – basic, pressed shapes, occasionally incorporating surface features or small holes for the location of other components in an assembly (eg. Props). The simple design of a plain batt means it is usually least-prone to failure.
(2) Extruded Batts – These are used to reduce thermal-mass while maintaining a good strength: weight ratio. They are commonly used for sanitaryware kiln cars.Extruded batts can be split into ten sub-categories as follows: Extra Large Batt, Extra Thin Batt, Plain Batt, Perforated Batt, Grooved Batt,Trapezoid Batt, Recessed Batt, Full Disc, Half Disc and Special Batt.
(3) Perforated Batts – sometimes referred to as Multihole batts, these are pressed or cast with several holes to reduce weight or allow air circulation through the batt.
