Carbon content can significantly affect the hardness of an alloy. The harder the alloy, the greater its resistance to fatigue. Too much carbon can make the steel brittle. In order to achieve this, carbon raisers are used to regulate the amount of carbon in the steel alloy.
This chemical is added to molten steel to increase the carbon content. It also helps it harden. This allows the metal to be molded and cast into different shapes. The carbon raising agent also increases the durability of finished castings. Due to these reasons, chemistry is commonly used in the production of wrought-iron and other forms steel.
The major source of carbon in the steel alloy is petroleum coke. The raw material must be distilled, or vacuum-distilled to remove impurities. It is then coked into petroleum coke. This is then calcined into carbon raiser which is used in the steelmaking processes.
There are several types of carbon raising agents. The most common is calcined anthracite coal, but there are also graphitized petroleum coke carbon raisers and electrically calcined anthracite. They are all added to molten ferrous iron in the steelmaking process. All of them must meet certain specifications, such as a high content of fixed carbon and ash and sulfur.
The carbon raiser should also be free of nitrogen and phosphorus. All are vital for maintaining steel integrity during smelting. They also must be dry and have a moderate particle size.
When scrap steel is placed in the electric furnace, a small amount of carbon raising agent can be added. The carbon in the alloy must be properly recarburized to avoid excessive oxidation. In the event that too much iron or steel is added, it will prevent the alloy from hardening properly and result in poor casting properties.
Increasing the temperature of the steel during heating is another way to increase its hardness. This can be achieved by increasing heat or using both. Increased temperature can reduce the brittleness.
A carbon additive allows the manufacturer to alter the levels of yield and tensile. This is critical for high-quality, durable products. Carbon additives may also be used in other applications including castings for automobiles and machinery. When the brake disc of a motor vehicle is manufactured with carbon raiser it will have an organized microstructure, and its sizes are designed scientifically. This will increase safety and improve brake performance. It will result in a constant friction coefficient and reduce wear on the disc. The disc will be protected from cracks. It is particularly important for heavy-duty vehicles, which require high levels braking force.
