Abstract

The invention discloses a carbon material cold ramming paste which is obtained by mixing and ramming following raw materials of, by gross weight, 45%-70% of calcined anthracite, 8%-20% of metallurgical coke, 0%-60% of artificial graphite, 13%-15% of coal tar, 3%-5% of anthracene oil or wash oil, 0.5%-5% of sulphur, 0.5%-5% of 2,4-dinitrotoluene and 0.5%-5% of 1,3-dinitrotoluene. According to the carbon material cold ramming paste, asphalt is not required for being used as an adhesion agent, heating is not required during production and construction processes, the cold ramming paste can be directly used on required portions for ramming, intermittent construction can be performed, and the ramming quality of the cold ramming paste is obviously superior to that of cold ramming paste and hot ramming paste in the market.

Description

technical field [0001] The invention belongs to the technical field of carbon products, in particular to a cold stamped paste. Background technique [0002] At present, the cold or hot paste used in the aluminum electrolysis surrounding paste, carbon paste, and ferroalloy smelting process requires asphalt as a binder, and high temperature (100°C-140°C) kneading is required in the production process. During the construction process, it needs to be heated and stirred or fried. During the process of stirring and frying paste, the asphalt fume emitted will cause serious damage to the human body and waste energy. The paste that needs to be heated must be tamped at one time within a certain temperature range. Contents of the invention [0003] The technical problem to be solved in the present invention is: [0004] Provide a carbon material cold ramming, which does not require asphalt as a binder, does not need to be heated during production and construction, and can be const...
