SDAF105b Ash Fusion Tester

SDAF105b Ash Fusion Tester

SDAF105b Ash Fusion Tester can be used to determine the ash fusibility of coal and coke ash in power plant, coal industry, metallurgical industry, cement industry, paper manufacturing and
9 samples each batch
Automatic sample introducing / taking mechanism
Product description

High automation, large number of samples/ batch.
①Unique automatic sample introducing/ taking mechanism. Operator only need to take it from the outlet under room temperature.  
②9 samples/batch. Fully automatic, test time/batch is 3 hours. Each month (22 working days) 100 samples more than normal tester.
③Applicable to different test atmosphere. Furnace temperature can be up to1600℃, applicable to ash of vast range of coal and coke.
Optimized design, Low operation cost.
①CE certified high definition camera and radiator reduce heat radiation and realize vivid picture and long service life.  
②Single layer or multilayer design for graphite cup increase utilization efficiency of graphite or bituminous coal. Test atmosphere in furnace is ensured.
③Anti-overflow slot in ash cone support can store spilled ash cone and prevent ash cone stick with the plate. 
④Furnace adopts heat resistant and heat insulation material. Imported material for combustion tube and sample boat.
⑤Heating element by silicon molybdenum rod, resist to high temperature (max. temperature 1800℃), anti-oxidation and low aging.
Real time monitor, Precise result.
①CCD camera real time monitor, new image processing algorithm, quick and accurate analysis of characteristic temperature.   
②Manual observing and camera recording of image at the same port. Good air tightness, low gas consumption.
③Gas leakage detection and alarm function make the instrument safe and reliable.
Smart control, easy to operate.
①Friendly interface, easy operation, real time display of image and data; All data can be stored, printed  and uploaded.
②Windows-based operation system for fully automated testing.
③Multi-control with CAN bus.
④Balance connection and data transfer with RS232 serial port.
