Abstract
The invention relates to a plugging compound used for carbon backing and is characterized in that the plugging compound used for carbon baking is alumina or alumyte kernels, the granularity of which are less than 6mm. The invention directly takes alumina and alumyte as plugging compound, or takes alumina and alumyte as the main raw material. After being ground, dispensed, mixed, pelleted and baked, the composite particles are obtained. The Coefficient of heat conductivity of the new baked plugging compound is better than that of the traditional plugging compound; the adsorptivity of the new baked plugging compound is greatly reduced compared with that of the traditional plugging compound. The products are not stick to the materials and the baking quality can be greatly improved.
Description
Technical field
The present invention relates to a kind of filler for calcining carbon.
Background technology
The sinter process of carbon product is one heat treatment step of carbon industry.Also be one critical process of decision quality product.Product is in roasting process, and along with a series of processes such as the discharge of softening, the volatile matter of product, bituminous coking, indexs such as the volume density of product, true density, resistivity, void content, intensity, antioxidant property are also correspondingly taking place to change.
Stopping composition plays secluding air in the roasting of carbon material, prevent the goods oxidation, and supporting role, also is responsible for a heat as heat-transfer medium simultaneously and passes to goods by the quirk wall, and form certain pressure atmosphere around goods.It is generally acknowledged that the ideal stopping composition should have good thermal conductivity, certain adsorptivity and ventilation property are arranged, but size is moderate.Not with goods and body of heater material generation chemical reaction.If the stopping composition thermal conduction is bad, can cause the product temperature control to lag behind, heat-up rate is slow, wastes energy, and also can cause the temperature difference between product simultaneously; Adsorptivity is strong excessively, will cause the pitch volatilization excessive, and binding agent coking rate will reduce, and the oxidation of goods and sizing also can be very serious.
The material that is usually used in doing calcining filler at present is after-smithing petroleum coke, metallurgical coke, calcined anthracite, and indivedual producers have ginseng to join river sand.The tradition stopping composition is not ideal, causes the quality instability, and index is on the low side.
Summary of the invention
The objective of the invention is deficiency, a kind of good thermal conduction, fast, the saving energy of heat-up rate are provided, effectively eliminate the temperature difference simultaneously, prevent the oxidation of goods and the filler for calcining carbon of sizing at above-mentioned prior art.
A kind of filler for calcining carbon, the stopping composition that it is characterized in that its calcining carbon are aluminum oxide or the calcining bauxite ore particles of granularity less than 6mm.
A kind of stopping composition that is used for calcining carbon of the present invention is characterized in that the sintering process of stopping composition aluminum oxide or bauxite ore particles is carried out under 1200-1500 ℃ of condition.
A kind of stopping composition that is used for calcining carbon of the present invention has characteristics such as thermal conductivity height, adsorptivity is low, ventilation property is low.The roasting product quality that similarity condition is produced down is higher than the quality with traditional stopping composition roasting.
Specific embodiments
A kind of filler for calcining carbon, the stopping composition of its calcining carbon are aluminum oxide or the calcining bauxite ore particles of granularity less than 6mm; The sintering process of stopping composition aluminum oxide or bauxite ore particles is carried out under 1200-1500 ℃ of condition.
A kind of filler for calcining carbon, the stopping composition that it is characterized in that its calcining carbon are aluminum oxide or the bauxite ore particles of granularity less than 6mm, and the sintering process of stopping composition bauxite ore particles is carried out under 1200-1500 ℃ of condition.
Embodiment 1
Use the green anode thickener experimental pressure machine with 200Kg/cm
2Defeat the sample of making Φ 56X75mm, totally 12, put into a roasting crucible for per 4, do calcining filler less than traditional metallurgical coke, the granularity of 6mm less than the aluminum oxide of 6mm and the bauxite that under 1200-1500 ℃ of condition, carries out with granularity respectively, carry out roasting in the laboratory in stoving oven, the result is as follows:
| Roasting is added and is filled material | Volume density | Resistivity | Intensity |
| Metallurgical coke | 1.56 | 60.8 | 38.7 |
| Aluminum oxide | 1.59 | 56.2 | 41.6 |
| The aluminium vanadine | 1.58 | 58.7 | 40.9 |
From the situation of coming out of the stove, slight oxidative phenomena is arranged at the top of being done the stopping composition in the crucible of stopping composition by metallurgical coke, and specimen surface has one of three parts sizing phenomenon, does not all have oxidative phenomena and do calcining filler with aluminum oxide and bauxite, the specimen surface of roasting is smooth, does not have the sizing phenomenon.From the quality of roasting, volume density and intensity all have raising, and resistivity has reduced, and therefore, can do calcining filler with aluminum oxide and bauxite, to reduce the loss in the calcining carbon process, improve the quality of products.
Claims (2)
1. filler for calcining carbon, the stopping composition that it is characterized in that its calcining carbon are aluminum oxide or the calcining bauxite ore particles of granularity less than 6mm.
2. a kind of stopping composition that is used for calcining carbon according to claim 1 is characterized in that the sintering process of stopping composition aluminum oxide or bauxite ore particles is carried out under 1200-1500 ℃ of condition.
