Abstract
The invention discloses a formed coke made from waste coke powder, comprising the following components: coke powder, binder and sulphur fixing agent; the formed coke made from waste coke powder in the invention is characterized by good water resistance, required strength and meeting the environment-friendly requirement in use. The invention further discloses a method for manufacturing the formed coke made from waste coke powder, with simple processing technique and low manufacturing cost.
Description
Technical field
The present invention relates to a kind of formed coke and production method thereof, particularly a kind of formed coke and production method thereof of utilizing useless coke end to make.
Background technology
The useless coke powder quantity that the employed metallurgical coke of smelting industry produces in broken, screening process is a lot, if be not used or handle, not only can cause energy dissipation, also pollutes the environment.There are a lot of technology that useless powdered coke shaping is studied and used at present.But, always have problems such as water tolerance or intensity difference.Chinese patent ZL94106771.8 discloses a kind of production method of caking coke of coke powder.But the binding agent of this forming method is a pitch, and smog emission is many during burning, causes environmental pollution, and the formed coke intensity of being produced can not meet the demands.
Therefore, need effectively utilize, produce water-tolerant, intensity height, sufficient combustion and the little formed coke product of environment protection influence to useless coke powder.
Summary of the invention
In view of this, the purpose of this invention is to provide a kind of formed coke and production method thereof of utilizing waste coke powder to make, formed coke product strength height, the water-tolerant produced can satisfy the Metal smelting needs, and simultaneously with short production cycle, technology is simple, and production cost is low.
The formed coke that make at the useless coke end of utilization of the present invention, this fuel comprises following component by weight percentage:
Coke end 90%-92%
Binding agent 7%-10%
Sulphur-fixing agent 1%-3%.
Further, this fuel comprises following component by weight percentage:
Coke end 91.5%
Binding agent 7.5%
Sulphur-fixing agent 1%;
Further, described binding agent is that coal tar, sulphur-fixing agent are calcium base, magnesium base or aluminium base sulphur-fixing agent;
Further, described formed coke product is spherical, cubic or other bulks.
Another object of the present invention is to provide a kind of method of making above-mentioned formed coke, this method may further comprise the steps:
(1) by following weight percent batching:
Coke end 90%-92%
Binding agent 7%-10%
Sulphur-fixing agent 1%-3%
(2) with the above-mentioned substance mixture, heat 380 ℃-400 ℃, mix bonding, extrusion molding;
(3) the extrusion molding mixture is put into the roasting kiln roasting, 280 ℃ of maturing temperatures--450 ℃;
(4) cooling is come out of the stove, and obtains the formed coke product.
The invention has the beneficial effects as follows: the formed coke that the formed coke that make at the useless coke end of utilization of the present invention utilizes waste coke powder, coal tar binding agent and sulphur-fixing agent to make, do not use pitch to make binding agent, water-tolerant, intensity can be satisfied the demand, and can satisfy environmental requirement during use; And complete processing is simple, and production cost is low.
