New roasting process
- October 22, 2020 New roasting process

The roasting process is actually a process in which the green body is carbonized into a binder coke through heat treatment. That is, the pressed green body is placed in a roasting furnace, and the air is insulated for heating. The binder undergoes a series of physical and chemical reactions at a certain temperature to form a certain thickness of coke film on the surface of the carbon aggregate. Through the binder coke, the carbon powder particles and the particles are connected into a whole with certain mechanical strength and physical and chemical properties.

Introduction to impregnation
- October 16, 2020 Introduction to impregnation

The purpose of impregnation is to fill the pores and open pores in the aggregate coke particles with impregnants such as molten pitch. After secondary roasting, the porosity or ventilation porosity is reduced, and at the same time, the billet’s Density, strength, modulus of elasticity, linear expansion coefficient, or can improve corrosion resistance and wear resistance, reduce gas and liquid permeability, improve conductivity, etc.

Purpose of roasting
- October 10, 2020 Purpose of roasting

After various carbon raw materials are kneaded and formed, although they have a certain size and shape in appearance, they are only a whole formed by the physical bonding of the binder. The binder is not carbonized (or coking), and its mechanical strength and physical and chemical properties The performance is far from the performance of carbon materials. Therefore, the process of heating treatment must be carried out in the carbon production process. This process of heating the green body in the protective medium in the heating furnace at a certain heating rate under the condition of isolating air is called roasting.
