Anthracite carbon casting formed coke

Abstract

Disclosed is anthracite carbon foundry formed coke which solves the disadvantages of uneven granularity, insufficient oxygen-adding, high broken rate and environment pollution found in the formed coke in the prior art; the anthracite carbon foundry formed coke is characterized in that the anthracite or non-coking coal is used to produce the anthracite carbon foundry formed coke; the steps include that the raw coal is conveyed to the factory, crushed and grinded to powder; the binder is added to the grinded powder and the mixture is stirred under the cooling condition, and then stirred evenly after being heated; the mixture is conveyed to the pressing machine for the extruding formation; the formed material is conveyed to the carbonization chamber and then is processed with dry distillation and carbonization under the conditions of air-isolation and the temperature ranging from 950 DEG C-1050 DEG C; finally, the formed material is cooled and the finished product is outputted to be stored in the storehouse for sale; the process of comprehensive utilization of the coke-oven gas generated in the carbonization chamber is set for the lime joint production; the process of dust removal and desulfurization is set for the flue gas and SO2 in the exhausted gas; based on the special binder formula and the special product structure and compared with the traditional coking method, the anthracite carbon foundry formed coke has the advantages of high carbon content, high calorific value, low ash content and sulfur content, crush resistance, abrasion resistance, good intensity, moderate reactivity, high intensity after reaction, good cold and heat intensity, reasonable and simple structure, small investment, low expense and specially being applicable to the coking and the mechanical casting industries.

Description

Technical field: [0001] The invention specifically relates to anthracite carbon casting mold coke, which belongs to the technical field of deep processing and utilization of coal resources and product manufacturing, and is suitable for refining anthracite carbon casting mold coke by utilizing anthracite coal. Background technique: [0002] As far as the inventor knows, the current coking industry produces coke with main coking coal as raw material, but the reserves of main coking coal are all very small in the world, especially in our country. The reserves are less than a quarter, which is far from meeting the needs of my country's economic development. The reserves of main coking coal cannot support the sustainable development of the coking industry, so the development of new coking technology is imminent. In the 1980s, the state encouraged the development of non-coking coal coking technology. Success, especially the anthracite coking technology has not yet broken through. ...

AI Technical Summary

Problems solved by technology

One is that if an inorganic binder is used, the ash content of the coke is increased; the other is that when an organic binder is used, the temperature difference between the melting point of the binder and the raw coal is too large, so that the reactivity of the coke is too high. High, the strength decreases after the reaction, the air flow is blocked, the combustion speed slows down, and the molten iron does not heat up quickly, etc.
