Glass lubricant for hot extrusion of titanium and titanium alloy as well as preparation method and application of glass lubricant

Abstract

The invention relates to a glass lubricant for titanium and titanium alloy hot extrusion and a preparation method and application thereof, in the glass lubricant, blank roll coating glass powder comprises the following raw material components: 25-55% of SiO2, 2-35% of B2O3, 1-12% of Al2O3, 0-5% of TiO2, 3-27% of Na2O, 0-15% of K2O, 2-20% of CaO, 1-10% of MgO, 0-10% of BaO, 0-5% of ZnO, 1-10% of CaF2 and 0-5% of C; the glass pad comprises the following raw material components: 30-65% of SiO2, 2-25% of B2O3, 1-12% of Al2O3, 0-5% of TiO2, 3-27% of Na2O, 0-15% of K2O, 2-20% of CaO, 1-10% of MgO, 0-10% of BaO, 0-5% of ZnO, 0-10% of CaF2, 0-5% of Na3AlF6 and 0-5% of C. By adding new components and adjusting the use amount of the components, the glass lubricant has the advantages of large temperature interval, low softening point, high melting speed, good peeling performance, good lubricating effect, weak corrosion to titanium and titanium alloy, high corrosion resistance, high corrosion resistance, high corrosion resistance, high corrosion resistance and the like. The surface quality of titanium and titanium alloy is good, and the service life of the die is long.

Description

technical field [0001] The invention relates to the technical field of hot extrusion of titanium and titanium alloys, in particular to a glass lubricant for hot extrusion of titanium and titanium alloys, a preparation method and application thereof. Background technique [0002] As an important strategic material, titanium and titanium alloys have many advantages such as low density, high specific strength, good fatigue resistance, excellent corrosion resistance, and good biocompatibility. They are indispensable keys in many modern high-tech fields. Materials are called "strategic metals", "ocean metals" and "space metals". At present, titanium and titanium alloys are widely used in aerospace, marine engineering, national defense, medical, metallurgy and chemical industries, and are key raw materials for the development of high-end manufacturing. [0003] Hot extrusion is one of the important means of metal profile production. In order to obtain good surface quality, reduce...
