Abstract
The invention relates to a method for preparing a calcium carbide smelting raw material from quicklime powder and Ramsbottom coke powder. The method is characterized by including the following steps that the Ramsbottom coke powder, the quicklime powder, coking coal, fat coal and asphalt are mixed uniformly, heated, stirred, extruded into pellets and naturally cooled to obtain the calcium carbide smelting raw material. Abandoned chippings of Ramsbottom coke blocks and quicklime blocks are effectively used, resources are saved, and environment is protected. The raw materials used in the method does not need to be ground, the requirement for the raw material size is low, and the operation process is simple; a small amount of coking coal fat coal rich in adhesive substance is added into the raw material, the addition amount of the asphalt adhesive substance is reduced, and meanwhile high-temperature adhesive performance and anti-crush performance of the pellets are improved.
Description
Technical field
The present invention relates to coal chemical technology, be specifically related to a kind of calcium lime powder and semi-coke powder preparation electricity
The method of stone raw materials for metallurgy.
Background technology
Tradition carbide carries out smelting preparation, this side with block coal and lump lime for raw material
Method makes carbide preparation there is numerous and diverse lime calcining process, block coal and Calx contact area
Little, power consumption greatly, easily produces the problem such as a large amount of dust and raw material chip, and these raw materials
Chip brings a certain degree of waste and problem of environmental pollution further.Therefore, the most effectively
Semi-coke chip and quick lime chip is utilized to become current prominent and stubborn problem.Owing to semi-coke is broken
Bits and quick lime chip are respectively provided with the characteristics such as size heterogeneity, impurity is many, caking property is low, therefore
Cause its very difficult molding.In the face of this difficult problem, there has been proposed multiple feasible proposal, such as:
Adding a certain amount of additive in raw material chip, mix and blend is hot-forming etc..
In the carbide raw materials for metallurgy preparation method that prior art provides, the requirement to raw material is the most severe
Carve, relatively costly, and complicated process of preparation, it is unsuitable for large-scale industrial production.
Summary of the invention
It is an object of the invention to the defect existed for above prior art, main purpose of the present invention
In place of being to overcome the deficiencies in the prior art, it is provided that a kind of with low cost, simple carbide of method
Raw materials for metallurgy preparation method.
Specifically, the invention provides a kind of calcium lime powder and semi-coke powder is prepared carbide and smelted former
Material method, comprise the following steps: by Ramsbottom carbon powder, quick lime powder, coking coal, rich coal and
Colophonium mix homogeneously, heated and stirred, it is squeezed into pelletizing, natural cooling,.
Ramsbottom carbon powder of the present invention, quick lime powder particle diameter at below 5mm.Described coking coal,
The particle diameter of rich coal and Colophonium is at below 1mm.
Wherein, the fixed carbon content of described coking coal is more than 70%, and the fixed carbon of described rich coal contains
Amount is more than 65%, and described coal tar pitch is coal tar pitch.
In order to strengthen the combination property of gained carbide raw materials for metallurgy, described calcium lime powder, semi-coke powder,
Coking coal, rich coal, the mass ratio of Colophonium are preferably 100:130:5～20:5～20:5～14.
The temperature of described heated and stirred is 100～200 DEG C.The time of described heated and stirred is 10～30
Minute.
Described extruding preferably employs roller ball press.The pressure of described extruding is 10～15MPa.
The present invention protects the carbide raw materials for metallurgy using described method to be prepared from further.
The calcium lime powder of present invention offer and semi-coke powder are prepared the method for carbide raw materials for metallurgy and are had
Following significant advantage: the process efficiently utilizes the debris of semi-coke block and caustic lime block,
Economize on resources, protect environment；The method is raw materials used is not required to levigate process, raw materials size
Asking low, operating process is simple；Raw material adds a small amount of burnt rich coal rich in bonding matter as interpolation
Agent, decreases the addition of pitch binder, also enhances the high temperature bond performance of pelletizing simultaneously
With anti-crushing performance, be suitable to large-scale industrial production.
