ADAPTATION OF PROOF FIXING SYSTEM FOR ASTM D-6200 COOLING CURVE TEST

摘要

Utility model patent, which covers the technical standards of the American Society for Testing and Materials, aims to improve the standardized fastening system in the astm d-6200 standard. This standard establishes the use of a standard specimen, which is connected to a mineral thermocouple, and this assembly is immersed in the quenching medium. In this application, we claim an innovation in the specimen clamping system, the modification of which was considered important in view of the need to reproduce the multi-piece test, the unfeasibility of the welding process, which increases the cost of the test, its time to preparation of the set, as well as making the thermocouple unfeasible. The proposed modification involves replacing the welding operation with a threading process in the specimen, whereby the capsule used in various tests is practically exchanged, while maintaining the guarantee that contact with the cooling fluid is avoided. the thermocouple, preventing damage to it and measurement errors during the test. It is also proposed to replace the thermocouple support material with aisi 310 stainless material that has refractory properties.
