Molybdenum sheets
Molybdenum sheet is black brown, if washed by alkali, it will be silver gray metallic luster, can be produced according to the width and thickness provided by the user, the surface is smooth, flat, no heavy skin, lamination, crack, crack edge, impurities clamped in and other defects. The thickness > 0.7mm supplied in hot rolled condition, thickness < 0.7mm sheet is available in cold rolled or cleaned surface condition.
Molybdenum billet (raw material)- inspection - Hot rolling - Leveling and annealing - Alkali washing - inspection - Warm drawing - Vacuum annealing - Inspection - Cold rolling - Leveling - Shearing vacuum annealing - inspection - packaging
After the deformation after reaching more than 60% of the rolling process, the density of molybdenum sheet basically close to the theoretical density of molybdenum, therefore it has high strength, uniform internal organization and excellent high temperature creep resistance, which is widely used in production of sapphire crystal growth furnace reflective screen, cover plate, reflective screen in a vacuum furnace, tropical, fittings, plasma deposition sputtering target material, High temperature resistant boat dishes and other products.
After chemical cleaning is silver gray metal luster, according to the width and thickness of the production provided by the user, the surface is smooth, flat, no heavy skin, layering, cracks, cracks, impurities clamped in and other defects.
The key technology of producing high-quality molybdenum sheet is to grasp the quality of raw materials, standardize the operation rules and adopt reasonable production technology.
The key to improve the surface quality of molybdenum sheet is to control the production quality of the end face lapping process and the surface finish of the upper and lower surfaces, and then choose the advanced two-sided four-direction lapping machine, which can make the surface quality precision of the product reach the advanced level in the world.
