Abstract
A kind of metallurgical coke made by blue carbon with low cost and handy technology. The technique scheme is that it is composed of the following components (weight portion) : blue carbon 90-100, magnesium oxide 3-6, magnesium chloride 8-15, water glass 8-15, urea 1-5, cement 0.1-0.5. The preparation method includes the following steps: (1) weighing blue carbon, magnesium oxide, magnesium chloride, water glass water solution, urea, cement pro rata; then crushing the blue carbon to 3mm power; mixing the magnesium chloride and water according to 1:1 weight rate to prepare magnesium chloride water solution; mixing the water glass water solution and urea uniformly; (2) mixing the blue carbon, magnesium chloride and cement uniformly inner the first mixer; (3) transferring the mixed material from the step two to the second mixer through transport, adding the magnesium chloride water solution, water glass water solution and urea to the second mixer, then mixing uniformly; (4) sending to the forming machine to mold and can obtain the product.
Description
Technical field
The coke system of the invention belongs to and preparation method thereof field, especially a kind of metallurgical coke that utilizes blue charcoal making and preparation method thereof.
Background technology
For many years, both at home and abroad the raw material used of sintering metallurgical coke all is a coking coal.Along with the development of society, the coke consumption is increasing, existing steel production enterprise, and consumption was nearly ten thousand tons in one day, because the store content of coking coal is limited, therefore how to seek other raw materials and method comes the sintering metallurgical coke to become the new problem of a scientific research field.
Summary of the invention
One of purpose of the present invention provides a kind of with low cost, technology is easy a kind of metallurgical coke that utilizes blue charcoal to make.
Another object of the present invention provides a kind of making method of utilizing the metallurgical coke of blue charcoal making.
Technical scheme of the present invention is: the metallurgical coke that utilizes blue charcoal to make is characterized in that being made up of following components in part by weight: blue charcoal 90-100 part, magnesium oxide 3-6 part, magnesium chloride 8-15 part, water glass 8-15 part, urea 1-5 part, cement 0.1-0.5 part.
The metallurgical coke that utilizes blue charcoal to make is characterized in that being made up of following components in part by weight: blue charcoal 95-98 part, magnesium oxide 4-5 part, magnesium chloride 10-12 part, water glass 10-12 part, urea 2-4 part, cement 0.2-0.4 part.
The metallurgical coke that utilizes blue charcoal to make is characterized in that being made up of following components in part by weight: 95 parts of blue charcoals, 4.5 parts in magnesium oxide, 11 parts in magnesium chloride, 11 parts of water glass, 3 parts in urea, 0.3 part of cement.
Utilize the making method of the metallurgical coke of blue charcoal making, it is characterized in that comprising the following steps:
(1) weigh blue charcoal, magnesium oxide, magnesium chloride, sodium silicate solution, urea, cement in proportion, it is 3 millimeters powder that blue powdered carbon is broken into granularity; Magnesium chloride and water are mixed by 1: 1 weight ratio, make magnesium chloride brine; Sodium silicate solution and urea mixing and stirring; (2) in first stirrer, blue charcoal, magnesium oxide, cement are stirred; (3) by conveyor the compound that step (2) forms is transported to second stirrer, the aqueous solution, sodium silicate solution and the urea admixture of magnesium chloride joined in second stirrer, stir; (4) deliver to the shaper moulding, finished product.
Effect of the present invention is: blue charcoal is to process with cleaned coal, and intensity own is very little, and rotary drum can only reach 10-12, so combustion time is short, can only smelt cement, ferrosilicon, silicomanganese and iron alloy series, can not iron and steel smelting.The metallurgical coke that the present invention utilizes blue charcoal to make is made up of the component of following weight ratio: blue charcoal 90-100 part, magnesium oxide 3-6 part, magnesium chloride 8-15 part, water glass 8-15 part, urea 1-5 part, cement 0.1-0.5 part.Magnesium oxide is as tackiness agent, magnesium chloride, water glass, urea admixture are as the modification solvent or diluent, the modification solvent or diluent mixes the product that stirring is made with blue charcoal, intensity increases greatly, rotary drum can reach 76-83, can reach 90 minutes to 180 minutes combustion time, can reach the purpose of iron and steel smelting, therefore provide a kind of product that replaces traditional coke, this product to have two indexs to reach the metallurgical coke primary standard.
The present invention is further illustrated below in conjunction with not limiting embodiment.
