Description

A kind of cast moulding coal tar and preparation method thereof
Technical field
The invention belongs to casting molded coal field, it is more particularly related to a kind of cast moulding coal tar and its preparation side Method.
Background technology
Exploitation coke substitute technology is that solve high-quality caking coal shortage, meets the industry STRENGTH ON COKEs such as metallurgy, machinery, chemical industry Needs and mitigate environmental pollution effective way.Therefore, countries in the world put into a large amount of human and material resources one after another develops such skill Art, have been achieved with being in progress well.China lacks the good coking coal resource of low ash, low-sulfur, caking property, with steel and iron industry and machine Tool industrial expansion, coking coal resource day is becoming tight to rise steadily with price, forces people to go to study coke substitute production skill Art.Casting molded coal is the ideal substitute of foundry coke.Clean coal technology is control pollution, saves the energy and improve coal money The important technology of source utilization rate.One of main path of China's development Filter Tuber For Clean Coal is exactly to greatly develop shaped coal technology.By fine coal into Type produces moulded coal or formed coke, and the raw material or fuel of cleaning are provided for industry, coal resources can be not only saved, also with significant ring Protect benefit.
Coke substitute shaped coal technology is developed, can not only meet the needs of the industry STRENGTH ON COKE such as metallurgy, machinery, chemical industry, Coking coal resource can also be expanded, the overstocked problem of fine coal is solved and significantly mitigate environmental pollution.Casting type is produced using anthracite Coal technology, it is coal deep processing frontier.This technology is succeeded in developing, and can not only extend enterprise's industrial chain, improves enterprise Economic benefit, and meet Filter Tuber For Clean Coal developing direction and state coal Industry Policy, there are wide market prospects.
The content of the invention
Overcome the deficiencies in the prior art of the present invention, it is therefore an objective to which a kind of cast moulding coal tar and preparation method thereof is provided.Described Cast moulding coal tar has low ash, low-sulfur, high fixed carbon, high intensity, lumpiness uniformity, the spy such as crushing strength is good, the porosity is low Point.The present invention can sufficiently utilize resource, and anthracite and coke powder are allocated according to the cast moulding pit ash formed in component Usage amount, it ensure that the stability of the indices of product.
To achieve the above object, the technical solution adopted in the present invention is：A kind of cast moulding coal tar is provided, included smokeless Coal 60-70 parts, coke powder 20-30 parts, adhesive 5-10 parts.
The anthracite is content of ashes 8-10wt%, sulphur content content 0.8-1.2wt%.
Described coke fines size ＜ 0.3mm.
A kind of preparation method of described cast moulding coal tar comprises the following steps：
a）Anthracite and coke powder are dried respectively, drying temperature is 270-300 DEG C；
b）Filter out the anthracite that granularity is 3-5mm；
c）Adhesive is added, and is stirred, is delivered to forming machine shaping；
d）Dried after shaping, 30-40min is sintered at 700-800 DEG C, the end for reaching tunnel cave afterwards cools down；
e）After cooling, 10-15min is cleaned, obtains finished product.
The present invention can make full use of resource, and anthracite and coke powder can be replaced mutually in component, according to different product index It is required that or add deduct.Because anthracite and coke powder are low-sulfur, low-volatile mineral raw material, product physical index compares phase Closely, anthracite can be substituted with high-quality coke powder, and coke powder can be adjusted with anthracite.
Compared with prior art the invention has the advantages that：Cast moulding coal tar caloric value of the present invention reaches 7300- 7600J, 7-10% is higher by than like product；Fall index and reach 98-100%, 8-10% is higher by than like product；Coke throws stove rate 12%-13% is improved, coke 25%-35% can be saved.The present invention sinters the technology effect for the sintering that just reaches a high temperature at 700-800 DEG C Fruit, exactly raw material proportioning bring, and cast moulding coal tar has low ash, low-sulfur, high fixed carbon, high intensity, lumpiness uniformity, anti- The features such as broken intensity is good, the porosity is low, in fusion process, air quantity, blast wandering scope are small, furnace temperature is stable, and molten iron temperature is high, It is a kind of new material of casting smelting.
