Problems solved by technology

[0005] At present, there is no special paste for integral furnace building at home and abroad, and related companies sometimes have layered defects when using ordinary cold-rammed paste to build furnaces, and it is difficult to guarantee the volume density and durability of submerged arc furnace linings with ordinary cold-rammed paste. Performance indicators such as compressive strength, oxidation resistance, wear resistance and penetration resistance meet the various requirements of submerged arc furnaces in actual production. The requirements of energy saving, consumption reduction, high efficiency and production increase have important theoretical and practical significance to promote the low-carbon and high-efficiency development of my country's ferroalloy, yellow phosphorus and other metallurgical industries

Embodiment 1

[0034] The weight proportions of aggregates, binders and additives used for cold stamping for integral furnace building are as follows: 76 parts: 18 parts: 6 parts;

[0035] The weight ratio of the aggregate is: 35 parts of electric calcined anthracite, 20 parts of pitch coke, 45 parts of artificial graphite, and the particle size is 5mm;

[0036] The weight ratio of the binder is: 40 parts of modified coal tar pitch, 50 parts of coal tar, and 10 parts of anthracene oil;

[0037] The weight ratio of the additives is: 60 parts of 2,4-dinitrotoluene, 1 part of sulfur and 39 parts of titanium diboride.

[0038] According to the above formula, put the prepared aggregate into the kneading pot preheated to 60 ℃ and mix for 25 minutes, then add the binder and additives and knead for 40 minutes, and finally take it out of the pot and cool it, that is, it has higher density and strength, and is more Low porosity and expansion and shrinkage special cold paste product for integral furna...

Embodiment 2

[0043] The weight ratio of the aggregate, binder and additives used for cold ramming paste for integral furnace building is: 75 parts: 18 parts: 7 parts;

[0044] The weight ratio of the aggregate is: 35 parts of electric calcined anthracite, 20 parts of anode butt, 35 parts of artificial graphite, 10 parts of pitch coke, and the particle size is 10mm;

[0045] The weight ratio of the binder is: 40 parts of modified coal tar pitch, 50 parts of coal tar, and 10 parts of anthracene oil;

[0046] The weight ratio of the additives is: 54 parts of 2,4-dinitrotoluene, 1 part of sulfur, and 45 parts of aluminum phosphate.

[0047] According to the above formula, put the prepared aggregate into the kneading pot preheated to 80°C and mix for 15 minutes, then add the binder and additives and knead for 30 minutes, and finally take it out of the pot and cool it, that is, it has higher density and strength, and is more Low porosity and expansion and shrinkage special cold paste product fo...

Abstract

The invention discloses a preparation method of a cold ramming paste specially used for submerged arc furnace whole furnace construction. The cold ramming paste comprises, by weight, 75 to 82 parts of a skeletal material, 16 to 20 parts of a binder, and 5 to 10 parts of an additive. The preparation method comprises following steps: A, the skeletal material is smashed into particles with a particle size lower than 12mm, and is weighed; B, the smashed skeletal material is delivered into a mixing kneading pot which is preheated to 60 to 80 DEG C for 15 to 25min, the binder and the additive are delivered into the same mixing kneading pot for 30 to 40min of mixing kneading, and an obtained product is cooled to room temperature and packaged. The cold ramming paste is mainly used for submerged arc furnace whole furnace construction.

Description

technical field [0001] The invention relates to a preparation method of cold ramming paste, in particular to a preparation method of cold ramming paste specially used for integral furnace construction of submerged arc furnaces. technical background [0002] The masonry quality and service life of ferroalloy and yellow phosphorus smelting submerged arc furnaces directly affect the production efficiency and economic benefits of production enterprises. Modern submerged arc furnaces generally have the characteristics of closed continuous operation. The operation of renovating and building the furnace is difficult, labor-intensive, time-consuming, and expensive. important. [0003] The traditional submerged arc furnace masonry basically uses carbon bricks as the furnace building material for lining the high-temperature molten pool. When building the furnace, the gap between the carbon bricks and the carbon bricks is filled with carbon paste. The carbon paste between the carbon ...
