1> When the demand side has special requirements for silicon content, it shall be stipulated by the supplier and the buyer.
2> use of high-phosphorus ore smelting unit, subject to the approval of national authorities, pig iron phosphorus content allows not more than 0.85%.
3> In the chemical composition table, the figures after the effective number of sulfur and phosphorus contents are not allowed to be repaired.
4> When using copper-containing ore smelting, iron copper content greater than 0.30% is not allowed.
5> Each pig iron should be supplied in the form of iron or molten iron.
6> When each cast iron is cast into a block, it can produce two pieces of iron.
The block size specifies the blockiness as follows:
1> Small pieces of pig iron: 2 to 7 kg of pig iron per piece. The proportion of the sum of more than 7kg and less than 2kg in each batch is stipulated by the agreement between the supplier and the buyer.
2> Large pig iron: each piece of pig iron shall not be larger than 40kg, and there are two notches, and the thickness of the notch is not more than 45mm. The proportion of broken iron blocks of less than 4kg in each batch is stipulated by the agreement between the supplier and the buyer.
Iron blocks cast in cast iron machines should have a clean surface, but allow the attachment of lime and graphite .
For iron blocks cast on a cast bed, the surface slag and sand should be carefully removed, but lime and graphite are allowed.
ZXZ Automotive Bearings have good quality and long life, they are performance design projects summary.
Different kinds of auto bearings are customized to meet the various working conditions, and all of them need good quality and long life:
1. Alternator bearing:inner ring rotation with high sealing performance, can bear high speed rotation.high & low temperature environment.low starting torque and long life.
2. Tensioner pulley bearing:outer ring rotation with low load, but high requirement for temperature rising, grease leakage, anti-dust and anti-water in different conditions.
3. Electromagnetic clutch bearing:mostly are double row angular ball bearings, low radial load, rotation speed ≤6000rpm, according to the working principle of electromagnetic clutch, as the bearing need to bear axial force intermittent and surrounding with water and dust, so high requirement for grease leakage, anti-dust and water proof.
ZXZ design different types of auto bearings to meet the specific need of applications, and provide excellent solution to ensure that our clients derive maximum benefits from our products.
