Antirust Vacuum Furnace Parts Laser Cutting Molybdenum Heat Shield
Customized Set Furnace Molybdenum Heat Shield For Vacuum Furnace Parts
Description
Tungsten-molybdenum materials are suitable to be used for shielding at the temperature of 1,300℃ to 2,800℃, which reserve the heat in an effective interval in the modes of heat reflection and convection obstruction.Because of limited material features, tungsten-molybdenum screens are usually riveted, and can also be butt jointed or overlap jointed.Equipment for laser cutting and so on is used for blanking, so holes can be positioned accurately, thus avoiding assembly difficultiesDue to the adoption of special annealing and setting processes, shielding produced by Achemetal have smooth model and uniform spacing among all the layers.All the layers can be spaced by corrugated plates, U-shaped lattice bars or molybdenum wire springs and spacing rings, and can be fixed by molybdenum wires or tungsten wire cards as well as tungsten or molybdenum screws.Achemetal can also press reinforcing ribs for screens with thinner walls, to enhance their strength.
With mature processes, Achemetal can manufacture inner side screens according with tungsten-tungsten, tungsten-molybdenum and molybdenum-molybdenum.
