In order to ensure the steel quality, GB/T 1979 09CuPCrNi-A weathering steel plates should meet following requirements:
1. 09CuPCrNi-A weathering steel plates contain high content of weathering elements and low content of harmful elements.
When the weathering elements content of 09CuPCrNi-A weathering steel plate is high, the addition of 09CuPCrNi-A weathering steel plate will not make the melting pool cooled too much. It is particularly important for smelting of 09CuPCrNi-A steel. The low content of sulfur and phosphorus and other harmful elements can reduce the task of removing sulfur and phosphorus in smelting.
2. The composition is clear and stable. Clear and reliable chemical composition is the important basis for accurately calculating the dosage of GB/T 1979 09CuPCrNi-A weathering steel plates. The stability of composition is the prerequisite for accurately controlling the composition of molten steel.
3. Proper block degree. The size of the block is determined by the melting point, density, addition method and furnace capacity of GB/T 1979 09CuPCrNi-A weathering steel plates.
4. Full bake. The GB/T 1979 09CuPCrNi-A weathering steel plates used in the furnace, especially during the reduction period, must be roasted to remove moisture and gas.
BBN GB/T 1979 09CuPCrNi-A weathering steel plates meet all the above standards, and are spoke highly in the steel industry.
