Abstract
A manufacture process of regenerated coke pertains to coke production technique, which is characterized by screening, roguing and cracking collected coke breeze at first, mixing with a weight proportion of coke breeze: 80-120, cement: 6-10, calcareous water with a content of 8-12%: 20-40, fully stirring into pasty; pouring the pasty into tubular shaped mould, demoulding after vibrating; naturally drying for 2-4 days at last to obtain regenerated coke. Regenerated coke produced by the invention is uniform in shape and size, mild in hardness and intensity, easy to burn and complete in combustion, strong in fire power, with few harmful gas emission such as carbon monoxide and sulfurous anhydride and without freezing of the funace, which can be widely used in industrial production fields such as metallurgy, cast, smelting, and also can be used as boiler fuel for hotel, dining hall, bathroom and so on. The product can be lot produced with easy produced mould and simple process, can substitute expensive metallurgical coke, so that cost is saved, economic benefit is improved, thus the invention has a wide market outlook and good environmental protecting effect.
Description
Technical field
The invention belongs to the regenerative coke production technical field, be specifically related to a kind of production method of regenerative coke.
Background technology
Common coke is the high energy fuels that raw coal forms through high-temperature coking, have advantages such as fixed carbon height, monomer thermal value are big, ignition power is strong, smoke-free and tasteless, low-sulfur, be mainly used in industrial production fields such as metallurgy, casting, smelting, forging, but shape size disunity, hardness, intensity are not moderate, be not easy burning, and burning is not thorough.At present, coke can produce a large amount of coke breezes in the process of producing, transport, store, using, less owing to these coke breeze granularities, can not satisfy the requirement of ironmaking, process for making.Producer often is blended in a small amount of coke breeze serves as the coke sale in the coke, when a large amount of coke breezes is sifted out, producer or user generally serve as it common fuel uses such as dant, sometimes even it be used in during engineering paves the way, coke breeze phase STRENGTH ON COKE purposes significantly reduces like this, can not demonstrate fully the intrinsic value of coke, cause waste, and cause big area to take up an area of pollution for a long time; Second kind be with group's balls such as water glass coal tar or pitch after use, this method needs specific equipment such as rotary kiln to carry out hot consolidation can to use after with the physical strength that increases pelletizing, technical process is long, cost is high; The third be add entry, binding agent stirs, after being pressed into the coke ball, ball press utilizes again again, though this method has realized utilizing fast coke breeze to a certain extent again, but shortcoming is to use ball press to process, limited production efficiency, and the coke ball use range of producing also there is certain restriction.

Embodiment
The invention will be further described below in conjunction with accompanying drawing, and provide embodiment.
A kind of production method of regenerative coke is by following processing step: 1) the measured coke breeze of fragmentary dispersive matter is collected, through screening, impurity elimination, pulverizing; 2) the fixed carbon content after will handling by following weight proportion is 80-88%, granularity less than the coke breeze of 1cm earlier be not less than No. 600 cement of high index mixing and stirring, the liming that has added bonding, heat transfer, desulfuration, disinfection again mixes, fully stir into pasty state, coke breeze: 80-120, cement: 6-10, liming: 20-40, described liming concentration is 8-12%; Best weight proportion is: coke breeze 100, and cement 8, liming 30, described liming concentration is 10%; 3) pour above-mentioned paste into the tubulose forming mould, the demoulding behind the vibratory compaction; The polynuclear plane that described tubulose forming mould is made of plastic cement pipe 2 and the panel 1 of diameter 10-14cm, length 8-12cm, the panel of this tubulose forming mould is placed ground grading up, paste is poured into and is adopted the vibrator vibratory compaction behind the tubulose forming mould, scrapes off coke paste unnecessary on the panel and in addition smooth; The polynuclear plane that the tubulose forming mould preferably is made of plastic cement pipe 2 and the panel 1 of diameter 12cm, length 10cm is also produced the 20-30 cover and is arranged into a string pendulum and is placed on the smooth ground, so just can realize the processing of pipeline system; 4) coke after the maintenance demoulding is placed on the abundant place of sunlight, and is not touched, do not drenched with rain, and can make fixed carbon content like this after 3-4 days (2 days summers) is 70-75%, and ash is the regenerative coke finished product of 22-26%.
Blow-on is normally appeared begin to arrange in pairs or groups behind molten iron regenerative coke and conventional coke and is used for ironmaking, adopt a semi custom coke and half regenerative coke to substitute the consumption of conventional coke when in the past smelting iron now, and elder generation pours conventional coke in the stirring bucket, pour regenerative coke again into, the stirring bucket hangs on material is poured in the stove like this, regenerative coke just below, conventional coke is in the above.Regenerative coke relatively pine is on fire fast near the fire in a stove before fuel is added earlier, and it can bear the impact of throwing ore again to conventional coke more firmly in the above.The whole nation will have millions of tons of coke breezes not to be used effectively every year, if can be processed into regenerative coke, substitute expensive metallurgical coke, subtract the up to ten million tons of consumption standard coal, reduce the production cost of the pig iron, and directly macro-economic rersults are obvious.
