Factory Price For Sintering Molybdenum Crucible - Molybdenum heat shield – WINNERS Detail:

Product Description

As the heat insulation component in the vacuum furnace , the biggest function of the heat shield is to block and reflect the heat in the furnace . Therefore , high-purity , accurate size , smooth surface, easy assembly ,  and  reasonable  design of  heat  shields  are  very  important .  Molybdenum heat shields  are  generally  produced and  processed with  0.5-1.2 mm  molybdenum sheets . Generally, there are 4-6 layers. The inner layer of the furnace is made of  high-temperature molybdenum TZM material with a thickness of 1.2 mm .  Molybdenum  strips  are  used  to  separate the  layers  with a space of 7mm .  Other  molybdenum heat shields are  made  of 0.5 – 0.8 mm MO1 material . Fasten them with molybdenum screws or molybdenum wire rods.

Molybdenum heat shield

Product Parameters

Products name Molybdenum heat shield
Available material Tungsten、Molybdenum、MoLaTZM、SS304(Stainless steel)
Thicknes 0.2~0.5~1mm

Design points of metal heat shield

Material thermal properties The maximum temperature of the selected metal material should be greater than the ambient working temperature, and the thermal deformation of the metal should be small. When the temperature is higher than 900℃, tungsten, molybdenum and tantalum sheets are generally used. Below 900℃, stainless steel sheet is generally used
material blackness Choose a material with low blackness, the reflection effect of the surface is better, and the surface finish is higher.
Material thickness The thickness of the screen should be as thin as possible. Molybdenum is generally 0.2~0.5mm, and stainless steel sheet is generally 0.5~1mm
material price Under the condition of meeting the working temperature, the cost should be considered
Determination of the number of layers of heat shield With the increase of the number of layers, the heat loss will decrease, the cost will increase, the structure will be complicated, and the vacuum degree will be more difficult to meet the working requirements. Increase to three layers to improve about 8%. The number of layers is not the better, and it should be considered comprehensively. The working temperature is 1000 ℃, and a maximum of 6 layers of screens can be used.
Spacing between each layer of heat shield The spacing should be minimized. The thermal effect of increasing the distance is not large. If the spacing is too small, the two layers of heat shields will be connected together due to thermal deformation. Reduce the spacing, generally about 10mm
connection between each layer Each layer of heat shield should be connected, and it should be ensured that the contact area of the connection is not too large, which will reduce the thermal efficiency. Use bushings and washers to connect each layer.
Maintenance of heat shields The heat shield should be designed to be easily removable, and the thermal expansion and contraction properties of the material should also be considered.
The distance between the first screen and the radiating surface Generally 50~100mm
The distance between the outermost screen and the circulating water wall Generally 100~150mm
