Description

Roasting furnace for carbon production

Technical Field

The invention belongs to the technical field of carbon roasting furnaces, and particularly relates to a roasting furnace for carbon production.

Background

Carbon and graphite materials are non-metallic solid materials based on elemental carbon, wherein the carbon material consists essentially of non-graphitic carbon and the graphite material consists essentially of graphitic carbon. Not only graphite but also carbon-containing materials including diamond, fullerene and carbene are called carbon materials. Carbon has a number of advantages: lightweight, porosity, electrical conductivity, thermal conductivity, corrosion resistance, lubricity, high temperature strength, heat resistance, thermal shock resistance, low thermal expansion, low elasticity, high purity, and good processability.

Carbon anode manufacture for aluminum production processes involves producing "green" anode blocks and firing these "green" anode blocks to produce anodes suitable for use in the aluminum production process. The production of "green" anode blocks involves mixing crushed coke or anthracite with a binder, such as a binder comprising coal tar pitch. The viscous mixture is then pressed to form a "green" anode block. The "green" anode blocks typically weigh from several hundred kilograms to more than one ton, depending on the smelting plant requirements. The mixture of coke and pitch binder typically cures at room temperature and softens at temperatures in excess of about 50 degrees celsius. The volatile components are released at temperatures between 50 and 400 degrees celsius. Upon further heating to about 1200 degrees celsius for a further period of time, the anode hardens, resulting in better physical properties, such as electrical conductivity and oxidation resistance.

The present invention provides a system and method for controlling a sacrificial medium used to surround a carbon body in a baking furnace path. Volatile extraction systems and methods are provided. Systems and methods for unloading a calcined carbon body are provided; however, in the prior art, the sacrificial medium is slowly sintered and flows downwards to separate from the carbon rod in the roasting process of the carbon rod, meanwhile, the coal tar pitch in the carbon rod overflows and is sintered outwards after being subjected to high temperature, part of the unsintered coal tar pitch is mixed with the fluid sacrificial medium and then drops on the grate, and further the mixture is adhered to the grate to be burnt and agglomerated, so that the ventilation effect of the grate is seriously influenced, and the oxygen supply and the stable burning temperature in the grate are influenced.
