| Microstructure | Perlite or pearlitic-ferritic. Graphite: a form - КГф2, КГф3; size - КГД15 - КГД90; distribution - ПГр1 - ПГр3. Perlite: footprint - П70-P45; dispersion - ПД0,3 - ПД1,0. Fosfina the eutectic (nature of distribution) - ФЭр1, ФЭр2. Cementite is not allowed. |
| terms of Use | The use of castings made of cast iron notificationname in friction requires careful installation, providing the pair of the friction surfaces and the absence of bias; continuous lubrication, permitting true and significant heating of the friction units; increase of the gap compared to the established bronze 15-30%, in the presence of significant heating osetreni in the work - up to 50%; running at idle and progressively higher loads. At a pressure of P≤0.5 MPa sliding speed V must be ≤5.0 m/s and the product P·V ≤ 2.5 MPa·m/s At a pressure of P≤12,0 MPa sliding speed V must be ≤1.0 m/s and the product P·V ≤ 12,0 MPa·m/s. |
