A continuous reheating industrial furnace is large inertia,pure delay,multi-variables,time-vary-ing,intercoupling complicated controlled plant,and has many uncertain factors.
Single chamber high pressure gas quenching vacuum furnace,double chamber and multichamber vacuum furnaces implementing the acetylene low pressure carburizing were briefly introduced.
In this study, gallium nitride nanowires were successfully grown on Silicon substrate using a simple resistive heated furnace, APCVD system, at room temperature.
