The Production and Applications of Molybdenum Plate

Molybdenum metal has very wide applications due to its good characteristics of corrosion resistance and high abrasion resistance. In the glass melting industry, molybdenum electrode is used to melt glass; in the automotive industry, MoS2 is an additive for solid grease; molybdenum target is used in the electronics and semiconductor industries. 

Material from 2mm to 76mm in thickness is classified as molybdenum plate. It can be used in in a diverse array of applications including precision sputtering targets, machining blanks, furnace hearth rails, x-ray shielding, nuclear fuel sintering boats, and others.

How to produce molybdenum plate? The following is its production process: 

Blank molybdenum plateinspectionhot rollingannealing alkali cleaninginspectionwarm rollingannealinginspectioncold rollingannealinginspectionpacking.

In the rolling process, starting from the billet rolling, the rolled piece undergoes plastic deformation under the action of the rolling force, resulting in work hardening. In the subsequent hot and warm rolling, usually one heating is accompanied by multiple passes, so that the two opposite processes of hardening caused by processing and softening of recovery recrystallization exist at the same time, that is, dynamic recovery and dynamic recrystallization occur; and the deformation is interrupted. 

Or the recovery and recrystallization that occur in the annealing, heat preservation process and subsequent cooling after termination are static recovery and static recrystallization, which are mainly reflected in the cold rolling stage. For rolled products or as raw materials for subsequent drawing, stamping and other processes, the process parameters in the rolling process determine the quality, performance and application of the plate itself.

After the blank plate is rolled with a deformation of more than 60%, its density is basically close to the theoretical density of molybdenum. Therefore, the product has high strength, uniform internal structure and excellent high temperature creep resistance. 

In addition, due to good thermal conductivity, in the process of using and working, the plate works steadily in cold or high temperature. Now good electrical conductivity has become an essential characteristic of material used in the electronic and electric equipment manufacturing industry.
