Closed Container for Melting Corrective Substances
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In foundries and steel plants, the addition of iron alloys, recarburizing substances, and machining waste to molten metals is challenging due to handling issues and oxidation, leading to processing losses as these substances are often exposed to flames and combustion before they can effectively contribute to the chemical composition of the final product.
Innovation Solution
A method involving a closed container made of compatible material that protects corrective substances from heat and oxidation by releasing them into the melting bath, allowing for the creation of a ready-made mixture that can be added to the metal, ensuring they interact with the molten metal without burning or oxidation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If corrective substances are added to molten metal using conventional methods, then the chemical composition can be adjusted, but the substances are exposed to flame and combustion causing oxidation and processing losses
Solution Approach 1:
The patent uses a container as an intermediary carrier to hold corrective substances during addition to the molten metal. This container protects the substances from direct exposure to flame and oxidation while enabling their controlled release into the melt, thereby maintaining chemical composition control while reducing processing losses.
Solution Approach 2:
The corrective substances are prepared and loaded into containers in advance before being added to the molten metal. This preliminary preparation allows the substances to be protected from oxidation until the moment of addition, ensuring they maintain their intended chemical properties for composition adjustment.
2Ease of operation
If sized pieces are used for corrective substances, then handling is easier, but the need for large-sized pieces increases and powders cannot be effectively used
Solution Approach 1:
The container serves as a mediator that enables the handling of corrective substances in various forms (powders, granules, pieces) without requiring them to be in large-sized pieces. The container provides the structural integrity for handling while allowing the contents to be in their most effective form for chemical composition adjustment.
Solution Approach 2:
The patent changes the physical state parameter of corrective substances from requiring large-sized pieces to allowing powders and fine granules by enclosing them in containers. This parameter change enables the use of materials in their most chemically active and effective forms while maintaining ease of handling through the container system.
3Productivity
If powders are used as corrective substances, then chemical function is optimized, but they are subject to oxidation and cannot transfer technical characteristics to the melt
Solution Approach 1:
The container acts as a protective intermediary that shields powder corrective substances from oxidation during handling and addition. This protection allows the powders to maintain their chemical integrity and effectively transfer their technical characteristics to the molten metal without being compromised by oxidative reactions.
Solution Approach 2:
The container creates a protected environment for the powder corrective substances, isolating them from oxidative atmospheric conditions. This inert environment preservation allows the powders to maintain their chemical properties until they are released into the molten metal where they can function effectively.
4Extent of automation
If mechanical shovels and cranes are used for handling, then automation is improved, but powder form materials cannot be managed in large quantities
Solution Approach 1:
The container serves as a mediator that enables automated handling equipment (mechanical shovels, cranes) to manage powder form materials in large quantities. By enclosing powders in containers, the system allows automated equipment to handle the containers as discrete units, thereby combining automation capability with the ability to manage large quantities of fine materials.
