1、The facility can do nondestructive online automatic selection to metal magnetic steel tube material

2、The facility adopts single frequency and three frequency to test

3、testing will be transferred to next machine by transfer roller,unqualified material will be marked or eliminated by sorting mechanism

4、It can count both unqualified material and qualified material 

5、The main control instrument of sorting machine has histogram ,it can dynamic display material state of steel。The amplitude of Histogram reflects ingredient change of steel,very intuitive

6、The main control instrument has setting function button of upper limit and lower limit of material range.,it is very easy for operator to operate,when ingredient of detected steel material higher than upper limit or lower the low limit,the instrument will instruct by relevant lights，at the same time,transfer both qualified and unqualified signal to sorting machine

7、There is showing light about steel tube material On the board of electric touching display screen in the sorting machine ,when the blue light is lighting ,it means the products are qualified,when the red light is lighting ,it means the kinds of material are not qualified

8、There are some functions about “database setting” “database searching” “historical database” “statistics” and “testing mode ” on the electric controlling touching display screen in the sorting machine.

9、The main control instrument of sorting machine can save  twelve kinds of steels with different specification and dimension,and show them on the top right corner by number one ,number two....respectively represent different specifications and dimension,very convenient for users to use directly。 

10、When detecting results are unqualified steels,the device has sound light alarm function。Simultaneously,mark red oil paint on steel surface 

1、Sorting speed ：<20S/piece 

2、Sorting accuracy :accurate to distinguish different steels ,make sure qualified material has no unqualified material。

3、Requirements on material，variety、seamless steel
