SPECIAL HIGH-STRENGTH CAST IRON WITH SPHERICAL GRAPHITE AS A NEW CONSTRUCTIONAL MATERIAL

Psyrkov N.V., Senior Engineer, PO "Gomselmash", Gomel, Republic of Belarus

The main results of research on the production of special high-strength cast iron (brand VCHTG) with high mechanical properties are presented. Preproduction series were produced from cast iron VCHTG for large gears on final drive for energy resources UES-2-250. Now they are on full-scale tests. From 2012, all forage harvesters KVK-800 are equipped with knives made of cast iron of this brand. This allows to provide almost the same operating time with the steel knives, to avoid catastrophic disruption throughout shredding and feeding system in contact with foreign objects. It is shown that from this cast iron possible make the counter boards for forage harvesters KVK-800 and KSK-600.
