KALIMPACT is a hard material hard material rubber composite. Depending on the specific abrasion and impact resistance requirements, KALIMPACT comprises either ABRESIST fused cast basalt, KALOCER oxide ceramics or with KALMETALL hard overlay welded plates. Each of the different material variations is formed into a vulcanised composite rubber sheet.
At a continuous casting plant steel ingots are cast and then cut to appropriate length. Due to the high temperatures, scale develops on the outside of the ingots and is rinsed away in chutes with water to a basin. The scale takes the form of grains some 5 mm in size and causes serious wear in the chutes. Nowadays it has become a standard throughout the world to line such chutes with ABRESIST fused basalt. The smooth surface reduces any deposition of material during transport, as well as protecting against abrasion wear.
In the preparation of iron ore, contaminated surface water travels at high velocity through channels to collection basins. The sharp-edged iron ore is highly abrasive to the concrete surfaces there. Frequent repairs are required as a result. Kalenborn lined the floor of the channels with smooth, wear-resistant ABRESIST fused cast basalt moulded elements. Wear-resistant KALCRET ANX hardening compound was selected to protect the less exposed walls. The combination lining has significantly extended service life and eliminated unscheduled repairs.
