Abstract

The invention discloses a roasting furnace, and particularly relates to a secondary roasting furnace for carbon products. The secondary roasting furnace is structurally characterized in that two rows of furnace chambers are symmetrically arranged on two sides of a furnace central line in a furnace body, each row of furnace chambers consists of a plurality of single chamber bodies, each single furnace chamber body is divided into n-1 material tanks by n flame paths, each material tank comprises flame path walls on two sides, transverse walls at two ends and a material tank bottom, a light heat-insulation furnace cover for sealing is arranged on the top of each material tank, volatile matter balancing channels are arranged on upper portions of the flame path walls, volatile matter flowing channels are arranged on upper portions of the transverse walls, ends of the two rows of furnace chambers are connected by communicating flame paths, volatile matter flowing control gate discs are inserted into the volatile matter flowing channels from tops of the transverse walls, smoke vents are disposed on upper surfaces of the transverse walls and communicated with smoke discharge devices, the smoke discharge devices are communicated with a main smoke flue, and flame path gate discs are arranged among the flame path walls of the adjacent single furnace chamber bodies. Asphalt volatile matters generated during roasting are guided to the high-temperature flame paths to be completed burned, and environmental pollution due to the fact that asphalt smoke is discharged into the atmosphere is thoroughly eliminated.

Description

technical field [0001] The invention relates to a roasting furnace, in particular to a secondary roasting furnace for carbon products in the field of carbon and graphite production and a roasting method thereof. Background technique [0002] Secondary roasting is the core process of producing high-grade carbon products and graphite products. Its function is to put the carbon roasted products impregnated with pitch into the secondary roasting device, and heat them according to a certain temperature curve under the condition of isolating the air. The asphalt immersed in the surface of the carbon product at a certain depth in the gap discharges volatile matter and realizes pitch carbonization, thereby improving the density and other physical properties of the carbon product, and producing high-grade carbon products, high-power and ultra-high-power graphite electrode blanks or other asphalt impregnated products. [0003] The existing secondary roasting process of carbon product...
