Abstract
The invention relates to a scrap steel pressed block made of granular and powdery scrap steel obtained by reprocessing steel slag of magnetic separation, and its characteristic: using the granular and powdery scrap steels and iron chips, the grade > 90% and the size 0-15 mm, as raw material, adding in sodium silicate binding agent in 5% of raw material weight, stirring uniformly and putting in a mould, and press-forming a pressed block by a press; the shape of the pressed block: the middle segment is a column, and two ends are both a cambered surface, and the pressed block can also be pressed into columnar, square, rectangular and spherical forms. The pressed block can be directly used in steel making, reducing two working procedures of sintering and iron-smelting, thus increasing the application value of the steel-making slag, and reducing consumption of energy and other materials.
Description
Technical field
The invention belongs to the comprehensive utilization of metallurgical industry revolving furnace steel slag, relate to a kind ofly use the particulate state that obtains after steel slag magnetically dressing is handled again, pulverous broken iron and steel is made a kind of broken iron and steel briquetting.
Background technology
At present,, only limit to both at home and abroad, and to obtain grade through magnetic separation be 40～60% steel slag magnetically dressing, as the raw material of sintered ironmaking technology its fragmentation for the processing of steel-making waste residue.This technology not only makes the using value of steel-making waste residue do not embodied fully, but also causes the waste of resource.
Summary of the invention
The objective of the invention is for the using value that improves steel-making waste residue and widen its Application Areas, alleviate the environmental pollution that steel-making waste residue causes, provide a kind of and use the particulate state that obtains after steel slag magnetically dressing is handled again, pulverous broken iron and steel is made a kind of broken iron and steel briquetting.
A kind of broken iron and steel briquetting content Description of the present invention:
A kind of broken iron and steel briquetting of the present invention, it is characterized in that: the particulate state that grade＞90% that obtains after steel slag magnetically dressing is handled again, granularity are 0～15mm, pulverous broken iron and steel, iron filings are raw material, the weight ratio of pressing raw material adds 5% sodium silicate binder, the mould of packing into after stirring is made broken iron and steel briquetting through pressing machine compression moulding; The shape of broken iron and steel briquetting is that interlude is that cylindric, two ends end face is the arc surface shape, and that broken iron and steel briquetting can also be pressed into is cylindrical, square, rectangle and sphere.
The present invention carries out deep processing to processed conventionally waste steel slag to handle grade＞90% that obtains after the steel slag magnetically dressing of back gained is handled again, the particulate state that granularity is 0～15mm, pulverous broken iron and steel, iron filings is that raw material is made broken iron and steel briquetting, can be directly used in steel-making, having reduced the steel slag magnetically dressing that existing explained hereafter goes out must be through oversintering and ironmaking two procedures.Thereby improved the using value of steel-making waste residue greatly, reduced the consumption of energy consumption and other material.Its grade is higher than the steel slag magnetically dressing of existing explained hereafter far away, thereby steel slag resource is fully used.

Embodiment
The present invention carries out deep processing to processed conventionally waste steel slag to handle the particulate state, pulverous broken iron and steel, the iron filings that obtain after the steel slag magnetically dressing of back gained is handled is that raw material is made broken iron and steel briquetting again, the present invention realizes like this, grade＞90% that obtains after steel slag magnetically dressing handled again, the particulate state that granularity is 0～15mm, pulverous broken iron and steel, iron filings are raw material, the weight ratio of pressing raw material adds 5% sodium silicate binder, the mould of packing into after stirring is made broken iron and steel briquetting through pressing machine compression moulding.See Fig. 1, the shape of broken iron and steel briquetting be interlude 1 for cylindric, two ends end face 2 is the arc surface shape.Broken iron and steel briquetting can be directly used in steel-making, and having reduced the steel slag magnetically dressing that existing explained hereafter goes out must be through oversintering and ironmaking two procedures.Thereby improved the using value of steel-making waste residue greatly, reduced the consumption of energy consumption and other material.Its grade is higher than the steel slag magnetically dressing of existing explained hereafter far away, thereby steel slag resource is fully used.
