Al-Sr Stick Aluminium-Strontium Performance characteristics
1. This product is a strontium containing aluminum strontium master alloy with excellent structure and is a new excellent long-term modifier. This product optimizes the morphology and distribution of eutectic silicon and improves mechanical properties.
2. This product is easy to use, no pollution, little loss, long-lasting effect, and the effect of remelting can be inherited.
Al-Sr Stick Aluminium-Strontium Scope of application
This product is suitable for modification of Hypoeutectic and eutectic Al Si Alloys with long casting time.
Al-Sr Stick Aluminium-Strontium Usage
1. Bake and dry before use.
2. Adding temperature: 720 ～ 760 ℃.
3. The addition amount of this product: 0.02 ~ 0.06% SR remains in the molten aluminum, which will have different degrees of modification effects on different alloys. The economic amount is determined by the test. The reference dosage of this product is 0.2 ~ 0.6% of the amount of aluminum (new material) to be treated. The strontium in the furnace return material is still effective and is not added.
4. Effective time of deterioration: 4-8 hours.
5. Operation method: put rod-shaped alloy modifier into molten aluminum, and stir evenly after melting; After standing for 20 minutes, remove the slag and pour the test rod. When the fracture is normal, pour it.
6. Fracture inspection: size of test bar in front of furnace Φ twelve × 100。 The normal fracture is silver white velvet, with fine and uniform grains and no silicon bright spots.
7. The modification treatment is generally carried out after refining, and there is no need to refine after the modification treatment to avoid affecting the modification effect.
