Tanlin brand recarburizer: Types and differences

In the field of steel smelting, recarburizer as a key additive plays a vital role in improving the quality and performance of steel. As a well-known brand in the field of carburants, Tanlin offers several types of carburants to meet the needs of different customers. This article will introduce the types and differences of Tanlin brand recarburizers in detail.

First, the type of Tanlin brand recarburizer

Coal recarburizer

Coal recarburizer is mainly made of anthracite by calcination, which has the characteristics of high fixed carbon content and moderate sulfur content. This kind of recarburizer is suitable for gray cast iron and steelmaking process, and can effectively supplement the carbon element in liquid iron. However, compared with other types of carburants, coal carburants may have a slightly lower carbon content and contain certain impurities.

Columnar graphite recarburizer

Columnar graphite recarburizer is the graphite pressed into a columnar form, with high fixed carbon content, low sulfur content, moderate nitrogen content characteristics. This kind of recarburizer is widely used in the smelting process of gray cast iron and ductile cast iron. Due to the microstructure of graphite, the columnar graphite recarburizer can decompose nucleation rapidly in liquid iron, and improve the nucleation ability and mechanical properties of liquid iron.

Petroleum coke recarburizer

Petroleum coke recarburizer is made by calcination of raw petroleum coke and has the characteristics of high fixed carbon content and moderate sulfur content. This recarburizer is suitable for gray iron casting and steelmaking processes and can significantly increase the carbon content of liquid iron. However, the ash and volatile content of petroleum coke recarburizer may be high, requiring further purification before use.

Graphitized petroleum coke recarburizer

Graphitized petroleum coke recarburizer is a product of petroleum coke after high temperature graphitization. It has the characteristics of high fixed carbon content, low sulfur content and low nitrogen content. This kind of recarburizer is one of the best quality recarburizers, which is mainly used in the smelting process of ductile iron. Because the graphitization process makes the arrangement of carbon atoms more regular, this recarburizer can decompose nucleation more quickly in liquid iron, and improve the carbon content and mechanical properties of liquid iron.

Second, the difference between Tanlin brand recarburizer

Raw materials and production process

Different kinds of Tanlin brand recarburizer have differences in raw material selection and production process. For example, coal recarburizer mainly uses anthracite as raw material and is calcined; The graphitized petroleum coke recarburizer uses petroleum coke as raw material and is treated with high temperature graphitization. These different raw materials and production processes lead to differences in carbon content, sulfur content, ash and volatile content of the recarburizer.

Performance and application

Different types of Tanlin brand recarburizers also differ in performance and application. For example, coal carburants are suitable for gray cast iron and steelmaking processes, but may have a slightly lower carbon content; The graphitized petroleum coke recarburizer has higher carbon content and lower sulfur content, which is more suitable for the smelting process of ductile iron. In addition, because of its special morphology and microstructure, columnar graphite recarburizer can decompose nucleation more quickly in liquid iron, and improve the nucleation ability and mechanical properties of liquid iron.

Cost and price

Different types of Tanlin brand recarburizers also vary in cost and price. Generally speaking, the production cost of better quality carburants such as graphitized petroleum coke carburants is higher and the price is more expensive; Coal carburants are cheaper. However, considering the important role of the recarburizer in the steel smelting process and its impact on the quality and performance of steel, it is often worthwhile to choose a recarburizer with better quality.

To sum up, Tanlin brand recarburizer has a rich choice in terms of types and differences. Customers can choose the most suitable recarburizer products according to the specific steel grade, smelting process and smelting equipment needs. Tanlin will continue to provide customers with high quality, stable recarburizer products and professional service support.
