Problems solved by technology

[0009] In view of the above problems, the present invention provides a test method for detecting the graphitization temperature, which is prepared by mixing coke aggregate and binder in proportion, kneading, forming and roasting to prepare a batch of graphitization temperature with the same diameter and thickness. The calcined blanks, take a part of the calcined blanks and carry out graphitization treatment at multiple temperature points, draw the temperature-graphitization curve of the calcined blanks, and then place the rest of the calcined blanks in various parts of the Acheson furnace along with the graphite material Carry out graphitization treatment, and finally deduce the final temperature of the graphitization treatment of the part according to the graphitization degree and temperature-graphitization curve of each part of the calcined billet, and solve the technology that the final temperature of the graphitization treatment of each part in the Acheson furnace cannot be measured problem, realize the determination of the graphitization level of graphitized materials in each part of the Acheson furnace

Embodiment

[0040] Such as figure 1 Shown, a kind of test method for detecting graphitization temperature, comprises the following steps:

[0041] Step 1, selecting raw materials, mixing coke aggregate and binder according to the ratio;

[0042] Step 2, kneading, kneading the mixed coke aggregate and binder to form a paste. The kneading temperature is 150-200° C., and the kneading time is 10-30 minutes;

[0043] Step 3, molding, molding the kneaded paste under a pressure of 100-200MPa, and keeping the pressure for 10-40min to form a green body;

[0044] Step 4, roasting, roasting the green body at 400-700°C for 1-3 hours to form a roasted product;

[0045] Step 5, reprocessing, processing the roasted product into a disc sample with a diameter of 20-30 mm and a thickness of 1-3 mm, and the diameter and thickness of the disc sample are consistent;

[0046] Step 6, draw the temperature-graphitization degree curve, select multiple temperature points as the graphitization temperature, respe...

Abstract

The invention provides a test method for detecting a graphitization temperature. The method comprises steps of raw material selection, mixed kneading, forming, baking, reworking, temperature-graphitization curve drawing and temperature measurement. A coke aggregating material and an adhesive are fixed based on a proportion; mixed kneading, forming, and baking are carried out to prepare one batch of baking blanks with same diameters and thicknesses; multi-temperature-point graphitization processing on parts of baking blanks and a temperature-graphitization curve one baking blank is drawn; the rest of baking blanks are placed at all parts in a Acheson furnace and graphitization processing is carried out with the graphite materials; and then according to the graphitization degrees and the temperature-graphitization curves of the baking blanks at all parts, final temperatures of the parts after graphitization are obtained by backstepping. Therefore, a technical problem that the final temperatures of all parts after graphitization treatment in the Acheson furnace cannot be determined is solved; and determination of the graphitization grade of the graphitized material in each part of theAcheson furnace is realized.

Description

technical field [0001] The invention relates to the technical field of graphitization temperature measurement in the graphitization process of graphite materials, in particular to a test method for detecting graphitization temperature. Background technique [0002] The current main heating furnace type for graphitization production in the carbon industry is the Acheson furnace. The graphitization heating principle of the Acheson furnace is to heat up the resistance material between the products first, then heat the product in the resistance material, and finally the product and the resistance The materials are heated together to reach the predetermined temperature. Since this heating process achieves the purpose through the self-heating of the resistance material and the product, the heating situation in the entire furnace is difficult to predict and control. Therefore, it is generally caused that the temperature difference of each point in the furnace of the Acheson furnace...
