The production technique of described intermediate super abrasion furnace black, its concrete steps are as follows:
The air that (1) will be compressed to 165～190Kpa is preheating to 700～800 ℃ through air preheater, delivers to the distribution plenum of Reaktionsofen through the hot blast pipeline;
(2) described fuel and additive are sent into the combustion chamber of Reaktionsofen, with the warm air mixed firing that above-mentioned distribution plenum is sent, temperature is controlled at 1900～1927 ℃.Described stock oil is sprayed into by the trunnion section of Reaktionsofen after the fuel oil preheating device is preheated to 180～260 ℃, through atomizing, shear, carries out the scission reaction of 6～20 microseconds at the conversion zone of Reaktionsofen, produces carbon black smoke;
(3) described carbon black smoke carries out chilling one time at the Reaktionsofen quench zone, passes through successively air preheater and fuel oil preheating device again, carries out at last the secondary chilling, makes its temperature be down to 260～290 ℃;
(4) carbon black smoke after the cooling enters main bag filter and collects, and the carbon black of collection is pulverized through micron disintegrator and delivered to the collection cyclonic separator by the wind fan;
(5) carbon black of described cyclonic separator collection is through granulator granulation, and the particle diameter that makes carbon black particle is 0.5-1.4mm, and the drying machine is dry again gets final product.
The most significant advantage of the present invention is: LX-LS200 carbon black products of the present invention; take Sweet natural gas as fuel; coal tar, carbolineum, mixing oil are mixed into stock oil with suitable proportion, and the stock oil of employing is rational in infrastructure, and carbon yield is higher; minimum and the narrow distribution of carbon black products particle diameter of producing; structure is lower, and the powdery carbon black makes behind micron disintegrator, tablets press, drying machine, mature preparation process; be fit to industrialized production, have significant economic benefit.
Carbon black products of the present invention (called after LX-LS200) belongs to medium super abrasion furnace black, in having super wear-resisting, improve and to collapse the advantages such as flower, breach performance, the shortcoming of the mixing difficult dispersion of super wear-resisting serial carbon black in also having improved simultaneously.Disperse grade point can reach about 7 grades through experimental analysis LX-LS200 carbon black particle, and the N219 carbon black particle that belongs to medium super abrasion furnace black together disperses grade point generally about 6 grades, can find out from above-mentioned separate data, LX-LS200 disperses grade point high by 15%～20% than common medium super abrasion furnace black, the shortcoming of the mixing difficult dispersion of super wear-resisting serial carbon black in namely having improved to a certain extent.
LX-LS200 carbon black products index of the present invention is as follows:
| Project | Index |
| Iodine absorption value g/kg | 110±5 |
| Oil-absorption(number) 10 -5m 3/kg | 78±5 |
