Powder material package method

Abstract

The invention provides a package method for adopting power materials as blocky materials to be directly used. The package method comprises the following concrete steps that A, screen materials are selected, and materials identical to the powder materials or identical to the materials of one or several ingredients required by the product production are adopted; B, the screen specifications are selected, the screen aperture is determined according to the powder material granularity, and the screen diameter is determined according to the package weight and the use requirements; C, the screen cutting mode and the screen cutting size are determined according to the package size and the package form; D, package and forming are carried out; and E, the powder materials are used as the blocky materials. The screen package method related by the invention can be used for packing the powder materials and making the powder materials into blocks, in addition, good ventilation performance is realized, and the high-temperature explosion defect of a sealed container is overcome. Although the method is simple, hidden danger of various kinds can be avoided, the cost is saved, and the energy sources are saved.

Description

technical field [0001] The invention provides a packaging method capable of directly using powder as a block, and belongs to the field of powder processing and application in industrial production. technical background [0002] In order to reduce costs and increase efficiency, Shougang Qiangang has carried out a series of finishing treatments such as crushing, ball milling, and magnetic separation on steelmaking steel slag, which has achieved significant direct economic benefits, but the iron content of 0-10mm particle size is more than 80% The powder or granules (called bean dregs steel and fish roe steel inside Qiangang) have been sold at low prices in the past. The main technical reasons are as follows: the particle size of the steel powder material is small, and the direct rotary furnace will generate a large amount of dust in the process of reversing and entering the furnace, which will increase the dust removal load of the converter and disturb the accuracy and stabili...

Problems solved by technology

The main technical reasons are as follows: the particle size of the steel powder material is small, and the direct rotary furnace will generate a large amount of dust in the process of reversing and entering the furnace, which will increase the dust removal load of the converter, and at the same time disturb the accuracy and stability of the feeding process

[0003] And because the closed container cannot be used to hold the powder in the rotary furnace, at present, the method of powder agglomeration is routinely used, and the refining process is carried out after agglomeration

There are two types of powder agglomeration processes: 1. Add water glass, bentonite and other binders to cold forming and then sintering process. The energy consumption is high and a large amount of silicon-containing substances are added, which will affect the steelmaking quality, output, and solvent consumption. Bad effects; 2. Direct cold forming process. This method has been used in the formation of iron oxide scales. It not only needs to add water glass, but also a certain proportion of cement. The composition is not easy to control, and the strength of the block is not guaranteed. Almost no one uses it anymore

Moreover, this return sintering method of powder agglomeration belongs to repeated processing, resulting in energy waste
