Product Introduction

Graphite petroleum coke recarburizer for casting is a commonly used recarburizer in the foundry industry. It is primarily composed of petroleum coke raw materials, processed through a specialized manufacturing process. This recarburizer boasts excellent thermal insulation performance and a highly effective recarburization effect. It is a crucial auxiliary material for enhancing the quality of castings throughout the casting process.

Production Process

The production process of the graphite petroleum coke recarburizer is comprised of the following steps:

Petroleum coke preparation: The by-product petroleum coke obtained from the coking process of petroleum coal is carefully selected to ensure a high fixed carbon content and low impurity content.

The graphitization treatment involves placing the petroleum coke in a resistance furnace for high-temperature treatment, which alters its structure and increases the degree of graphitization. This step is typically conducted in an oxygen-deficient environment to facilitate the smooth progression of the graphitization process.

Recarburization treatment: The graphitized petroleum coke is mixed with other raw materials and heated again to increase the total carbon content.

Crushing and screening: The mixture after recarburization treatment is crushed, and the product is obtained through screening equipment in the required particle size and uniformity.

Packaging and Storage: Crushed and screened products are packaged and stored in a dry warehouse to ensure that their quality and performance are not affected.

Graphite petroleum coke recarburizer offers a range of notable features and advantages within the foundry industry.

The product boasts a high fixed carbon content. The graphite petroleum coke recarburizer has a high fixed carbon content, which effectively increases the carbon content in castings.

It also offers excellent thermal insulation performance. The use of graphite petroleum coke recarburizer can delay the furnace temperature, provide a high temperature and constant temperature environment for casting, and facilitate thorough smelting during casting.

Enhance the quality of your castings with our product. The graphite petroleum coke recarburizer increases the number of eutectic spherules in molten iron and improves the distribution of graphite, thereby enhancing the quality of castings.

The reduction of production costs is a key objective. The use of a graphite petroleum coke recarburizer can reduce the amount of pig iron required for casting while increasing the amount of scrap steel, which in turn reduces production costs.

Application

Graphite petroleum coke recarburizer is a highly versatile product, widely used in the foundry industry across a number of different applications.

Enhance the mechanical properties of castings: By increasing the carbon content and improving the distribution of graphite in the castings, the mechanical properties and wear resistance of the castings can be enhanced.

Optimize the casting process: The use of graphite petroleum coke recarburizer can optimize the casting process, ensuring greater stability and control.

Reduce energy consumption: The high absorption rate and fast reaction speed of graphite petroleum coke recarburizer allows for shorter smelting times, reducing energy consumption and costs.
