Silicon carbide vacuum sintering furnace

Silicon carbide vacuum sintering furnace is used in ceramic materials, silicon carbide, silicon nitride vacuum sintering or atmosphere protection sintering process, it has gas circulation cooling system, furnace high temperature period take natural cooling, low temperature period can use positive inert gas charging method, get fast cooling speed. Low temperature period & high temperature period use different temperature control component to do temp control, changing-over automatically.

The control system was controlled by PLC, temperature was controlled by intelligent temp controller, accurate control, high automation. User can choose auto or manual undisturbed switching to operate it, this furnace has abnormal condition alarming function, easy to operate.

Environmental protection performance has been improved, maintenance cost saving, energy cost saving.
