The effect of correctly using carburizing agents for casting is that due to the high furnace temperature, a certain amount of carbon element is often lost, so special smelting materials are needed to supplement carbon. Casting carburetor is a special carbon supplement material developed specifically for the casting industry. Compared with traditional carburetors, they have better fixed carbon content, lower harmful elements such as sulfur and nitrogen that are harmful to castings. When used, carburetors have better effects and higher absorption rates. However, if the casting carburizing agent is not used properly, the effectiveness of the casting carburizing agent cannot be guaranteed.

The particle size of carburizing agents used in casting is generally 0-10mm. If there are special requirements, you can notify the manufacturer to customize. The general dosage is iron content × Require a carbon increase/recovery rate of 75%. When adding ingredients, carbon should be adjusted. According to the requirement of carbon content, metal furnace material is added to the molten iron, and casting carburizing agent is added to the middle and lower parts of the electric furnace. The carbon absorption rate can reach 85% -90%. When using carburizing agents for casting to melt, do not slag, otherwise it may be wrapped in waste slag and affect the absorption of carbon.

During casting, after the molten iron melts, the carbon content can be adjusted. Carburizing agents for casting can be added to the surface of molten iron, and carbon can be dissolved and absorbed through eddy current or manual stirring during electric furnace melting. The absorption rate of carburizing agents for casting can be around 85%.

Through the above explanation of the correct use of carburizing agents for casting, I believe everyone can correct the previous incorrect use method and make the effect of carburizing agents for casting better. The advantage of doing so is that it not only ensures the effectiveness of using carburizing agents for casting, but also saves production costs, killing two birds with one stone!
