Temperature uniformity |
≤ ±7℃. Measured by sintering of the FERRO ceramic shrink rings in the empty furnace under vacuum at 1450℃ on graphite trays. Can be soak in process (FERRO shrink rings should be supplied by the buyer.Suggest grade of 334,because the test ring are multifarious,The test only as reference,take below item3.16 as main test standard)
|
| 16 |
Parameter uniformity in sintered products
|
To be measured by sintering of the witness YG8 or YC40 grade hardmetal samples (with paraffin or PEG binder): max. magnetic saturation scatter ≤ ± 0,20%, max. coercivity scatter ≤ ± 0.3kA/m. Hardmetal witness plates to be delivered by the Buyer, the quality of the samples to be confirmed by the Seller.
