Step 3：The stainless steel band test sample of step 1 is placed on the weighing platform of balance, weighed, records weight
Data m1；
Step 4：Semiclosed lucite platform is covered on balance, closing space is formed between balance, is kept semiclosed
Lucite platform does not contact with the weighing platform of balance；Permanent magnet plane is placed with semiclosed lucite platform table top, record
Weight data m2；
Step 5：Repeat step three and step 4, obtain three groups of m1And m2；According to formula C=(m1-m2)/m1* 100% meter
Calculate heat treatment index C1, C2, C3, take three groups of statistical average CX, CX＜ 0.2%, then it is determined as that magnetic is qualified.
Lucite sealed compartment with door is set on the balance；The lucite sealed compartment bottom centre, which is set, to be lacked
Mouthful, for exposing weighing platform；In the step 4, the semiclosed lucite edge of table is set to cover on lucite sealing
On the gap edge of cabin bottom centre, do not contacted while closing space is formed with the weighing platform of balance.
In the step 4, ensure the weighing platform table top and semiclosed lucite platform table top and permanent magnet plane of balance
It is centrally located on the same straight line with horizontal plane direction.
In the step 4, after having recorded weight data, balance is resetted returned to zero immediately.
In the step 1, stainless steel band to be tested is prepared into 25mm≤length≤100mm, 10mm≤width≤
80mm, deviation ± 1mm regular oblong print.
In the step 2, balance uses minimum range 0.0001g, maximum range 210g AL204- assay balances；Forever
100 ± 1mm of diameter of magnet, thickness 20mm ± 1mm, magnetic induction intensity peak value are more than 1000GS；Semiclosed lucite platform
135 ± 5mm of mesa diameter, height 52 ± 5mm, 4 ± 0.5mm of wall thickness.
In the step 3, balance is returned to zero, reservation is small to count to 0.0001g.
Above-mentioned technical proposal is employed, the present invention efficiently and effectively can carry out magnetic detection, Er Qieshe to stainless steel band
Standby easily to prepare, method is convenient, as a result accurately.
