overview
Thermal bimetal strip is by the different expansion coefficient of
two or more than two layers of metal or metal solid combination,
and along the entire interface varies with temperature and the
thermal function of shape changes in composite materials.One of
high expansion coefficient become active layer, low expansion
coefficient becomes passive.When requirements with high
resistivity, but heat sensitive resistance performance is
essentially the same type of thermal bimetal series, can be added
between the two layers of different thickness of middle layer as a
shunt layer, is to achieve the purpose of control different
resistivity.
process
The manufacture of thermal bimetal key process is between every
layer composite technology.Composite process is legal, double pouring molten method, hot
rolling, cold rolling and explosion method, etc.Hot rolling method are commonly used, and in every layer of the
slab at high temperatures to with great hot rolled and compound,
and then for cold rolling.Product quality is the best method of cold rolling, the different
group of yuan layer slab at room temperature with large reduction
cold rolling and compound, then to conventional cold rolling.Normally thermal bimetal strip or sheet.
