Can-Eng Furnaces is at the forefront of the aluminum heat treating technology and will be showcasing its Basketless Heat Treating System (BHTS) for the efficient treatment of aluminum intensive automotive engine blocks, cylinder heads, structures and suspension components at GIFA 2011. The BHTS incorporates a unique material handling system that provides for single piece product flow. As result, this lean manufacturing concept transfers castings through the system without the use of baskets, carriers or trays. Can-Eng Furnaces Basketless Heat Treating System uses no baskets, trays or carriers and reduces energy consumption up to 40 %.

Traditional Calcium Aluminate Cement (CAC) bonded castables require significant time to dry out and allow water to evaporate. This is due to the low gas permeability (i.e. capability of vapour to escape through the structure) of CAC castables and the high amount of water trapped in hydrates crystals, which can escape at elevated temperatures only. Would the dry-out schedule not be respected, then vapour pressure inside the lining would rise up to values exceeding the strength of the castable and the lining would explode.

The company Fronberg Guss was able to considerably simplify ist handling of heavy moulding boxes. Heavy moulding boxes with a deadweight of up to 50 tonnes - it's hardly imaginable that such monsters can be rotated once around their own axis while hanging freely. Special endless chains are used for the rotating process using the Rotomax load turning device. These are equipped with a driving dog which engages with a trunnion on the moulding boxes, and thereby prevents the chains from slipping through.
