Embodiment Construction

[0019] 15-30 mm thick molybdenum slab → heating at 1200-1350 ° C for 40-60 minutes → hot rolling to 5-10 mm → heating at 800-1250 ° C for 30-40 minutes → 90 degrees reverse rolling to 2-5 mm →Surface treatment→Cold rolling to 1-2mm→Annealing at 800-940°C for 50-60 minutes→Reversing cold rolling to 0.3-0.8mm→Annealing at 800-940°C for 50-60 minutes→Cold rolling to 0.1-0.5 mm→annealing at 800-900°C for 50-60 minutes.

[0020] The metal molybdenum sheet with a thickness of 0.1-0.5 mm is stamped into a cup-shaped body with a diameter of 1 mm and a depth of 6 mm.

Abstract

The invention provides a material and manufacturing method used for manufacturing an LCD backlight source illuminant, in particular to the material to manufacture the LCD backlight source illuminant, which is made from metal molybdenum piece with a thickness ranging from 0.1 millimeters to 0.5 millimeters. The material manufacturing method is carried out according to the following steps: a Mo slab; hot rolling thinning; 90 degrees direction changing hot rolling thinning; surface treatment; cold rolling thinning; a first anneal; 90 degrees direction changing cold rolling thinning; a second anneal; cold rolling ranging from 0.1 millimeters to 0.5 millimeters; last anneal. The invention improves the pressing performance of the molybdenum piece to strike out 1 millimeter in diameter and 6 millimeters in depth cup shape body without anneal in the process, the yield ratio reaches more than 90 percent.

Description

technical field [0001] The invention belongs to the technical field of metal material processing, in particular to the processing of liquid crystal display backlight illuminant materials. Background technique [0002] The illuminant is the light source of the liquid crystal display, and the image we can see is the light emitted by the illuminant. At present, the backlight illuminants used in the market are mostly made of nickel sheet, because nickel has good plasticity and is easy to be stamped and formed, but its brightness is low, the color range is small, the contrast is low, and the life is short, which limits the improvement of picture quality. [0003] The present invention envisages that the disadvantages of making the luminous body from metallic nickel can be completely overcome by using molybdenum as the luminous body. However, the stamping performance of molybdenum is poor, and it is easy to crack when stamping the metal molybdenum sheet into a cup-shaped body wit...
