Silicon carbon alloy can be used as an effective deoxidizer in steel smelting, which can improve the quality of steel by removing oxides in molten steel. In the process of converter, electric furnace steelmaking and casting, silicon carbon alloy can effectively eliminate oxides in molten steel, so as to obtain high-quality steel.
Silicon-carbon alloys can form compounds with other elements in steel to strengthen and stabilize them. Silicon and carbon have an affinity for alumina, and can be reduced on aluminum to obtain two compounds, SiAl2 and SiAl4, of which SiAl2 can be further synthesized into other Si-Al alloys.
Silicon carbon alloy can improve the physical properties of steel, such as increasing strength and corrosion resistance, and improve the overall quality of steel.
The sulfur in the molten steel and the oxides formed during the production process will be precipitated in the slag. The carbon in the silicon carbon alloy can form sulfide with the sulfur, thereby reducing the sulfur content in the molten steel, and the oxide content in the slag.
Silicon carbon alloy procurement process may encounter some common problems, the following are some common silicon carbon alloy procurement problems and solutions:
The market price of silicon carbon alloy may be affected by many factors such as raw materials, supply and demand, and seasons, resulting in price fluctuations.
When signing a purchase contract, a price adjustment mechanism may be agreed, such as adjustment according to the market price index, or a certain price floating range may be agreed.
The quality of silicon carbon alloy may be affected by factors such as production process and raw materials, resulting in unstable quality.
When selecting suppliers, suppliers with perfect quality control systems should be selected, and product quality standards and acceptance methods should be clearly agreed in the contract.
Due to production, logistics and other reasons, the supplier may delay delivery.
When signing the contract, it is necessary to clearly agree on the delivery date and liability for breach of contract to ensure that the supplier can deliver the goods on time. If the supplier is really unable to deliver the goods on time, it can negotiate with the supplier to adjust the delivery date or take other remedial measures.
In the procurement process, there may be poor after-sales service, such as suppliers do not actively solve problems, difficulties in returning and replacing goods.
When choosing a supplier, it is necessary to choose a supplier with good after-sales service, and clearly agree on after-sales service terms and liability for breach of contract in the contract. If the supplier does not perform well in after-sales service, it can protect its rights and interests according to the contract.
