【Graphite Carburant】Knowledge Station – Quick Science Tip

Introduction

Graphite carburant refers to carbon materials whose molecular structure has been altered through high temperatures or other means to form a more orderly arrangement. This molecular arrangement features wider spacing between carbon molecules, making it easier to decompose and nucleate in molten iron or steel. Currently, graphite carburants on the market generally come from two main sources: one is waste cuttings from graphite electrodes, and the other is petroleum coke products that have undergone graphitization at 3000°C. 

Raw Materials and Process

There are many types of raw materials for carburants, and their production processes also vary. Contrary to some claims in the market, using graphite powder compressed into shape requires a large amount of binder, and the resulting carbon content usually does not meet the standards for high-quality carburants. Pressed graphite powder forms solid blocks without a porous structure, so its absorption speed and absorption rate are inferior to those of calcined or roasted carburants. High-quality carburants generally refer to those that have undergone graphitization. Under high-temperature conditions, the carbon atoms are arranged in a microscopic graphite structure, which is why it is called graphitized. Graphitization can reduce the impurity content in the carburant, increase the carbon content, and lower the sulfur content.

Applications

Graphite carburant is widely used in industry, serving as a carburizer in metallurgy and foundry. It is used in the manufacture of high-temperature crucibles for smelting, lubricants in the machinery industry, electrodes, and pencil leads. It finds wide application in advanced metallurgy for refractory materials and coatings, stabilizers in military pyrotechnics, pencil leads in the light industry, carbon brushes in the electrical industry, electrodes in the battery industry, and catalysts in the fertilizer industry.
It is extensively used in the foundry industry, especially in the production of ductile iron and gray cast iron. With stable quality, fast absorption speed, and high absorption rate, it has a unique inoculation effect, greatly reducing production costs. It can lower the consumption of carburants, energy, inoculants, nodulizers, furnace linings, defect rate, burning cycle, slag inclusion risks, and white iron formation.
