Reduction Furnace Charging Device for Iron Ore Segregation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In smelting reduction methods, iron ore is not uniformly dispersed in reduction furnaces, leading to segregation issues during the formation of molten iron, which affects the efficiency and quality of the reduction process.
Innovation Solution
A reduction furnace design incorporating a charging device with a first guide plate sloped in one direction and a second guide plate sloped in a direction intersecting the first, along with a guide tube system, ensures uniform dispersion of iron-containing materials by adjusting the dropping direction and preventing segregation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If iron ore is directly charged into the reduction furnace without additional devices, then the charging process is simple, but the iron ore cannot be uniformly dispersed and segregation occurs
Solution Approach 1:
A charging device is introduced as an intermediary component between the charging hole and the reduction furnace. This device includes a guide tube with first and second guide plates that redirect the flow of iron-containing material, causing it to drop and disperse uniformly into the reduction furnace while preventing segregation. The intermediary charging device thus resolves the contradiction by maintaining relatively simple construction while achieving uniform dispersion.
Solution Approach 2:
The charging device segments the charging process into distinct stages: the guide tube receives material from the charging hole, the first guide plate directs it in a first direction, and the second guide plate redirects it in a second direction. This segmentation of the material flow path enables uniform dispersion while keeping each individual component simple in structure.
2Stability of the object's composition
If a charging device with multiple guide plates is added to prevent segregation, then uniform dispersion of iron-containing material is achieved, but the device complexity increases
Solution Approach 1:
The charging device is segmented into simple, discrete components: a guide tube, a first guide plate, and a second guide plate. Each component has a single, straightforward function - the guide tube receives material, the first guide plate directs it in one direction, and the second guide plate redirects it in another direction. This segmentation achieves uniform dispersion while keeping the overall device complexity relatively low.
Solution Approach 2:
The charging device utilizes dimensional changes in material flow direction. The first guide plate directs material in a first direction, and the second guide plate redirects it in a second direction that intersects the first direction. This change in dimensions of material flow achieves uniform three-dimensional dispersion while maintaining simple two-dimensional plate structures.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively prevents segregation and ensures uniform distribution of iron-containing materials within the furnace, improving the reduction process and the quality of molten iron production.
Implementation Method 1
a first guide plate sloped toward a first direction in the reduction furnace to guide the iron-containing material to the inside of the reduction furnace
Implementation Method 2
a second guide plate fixed and sloped toward a second direction intersecting the first direction in the reduction furnace to guide the iron-containing material dropped and guided by the first guide plate. A dropping direction of the iron-containing material that is dropped and guided by the first guide plate is changed when the iron-containing material is guided by the second guide plate

AI summary
An apparatus for manufacturing molten iron includes a reduction furnace having a charging device that is capable of preventing segregation. The reduction furnace for reducing an iron-containing material used for manufacturing molten iron may include a charging hole where the iron-containing material is charged, a first guide plate sloped toward a first direction in the reduction furnace to guide the iron-containing material to the inside of the reduction furnace, and a second guide plate fixed and sloped toward a second direction intersecting the first direction in the reduction furnace to guide the iron-containing material dropped and guided by the first guide plate. A dropping direction of the iron-containing material dropped and guided by the first guide plate is changed when the iron-containing material is guided by the second guide plate.
