Extrusion Press Container Mantle Thermal Profile Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Achieving thermal alignment in metal extrusion presses is challenging due to temperature variations within the extrusion press container, which affect the uniformity of the billet temperature and flow rate, leading to inefficiencies and product defects.
Innovation Solution
A mantle for the extrusion press container with serpentine grooves and elongate heating elements, along with a fluid channel for cooling, allows for precise control of thermal energy and fluid flow to maintain optimal temperature profiles across the container, using temperature sensors and individually controllable heating sections to address temperature discrepancies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If cooling means are introduced into the container to control temperature, then temperature profile control is improved, but device complexity increases
Solution Approach 1:
The container is divided into multiple heating zones with independent temperature control. Each zone can be controlled separately to achieve the desired temperature profile, allowing precise temperature management without requiring complex cooling systems throughout the entire container.
Solution Approach 2:
Different sections of the container are provided with different heating capabilities and temperature control characteristics. The heating means are distributed at different locations (e.g., upper and lower sections) to create localized temperature control, addressing specific thermal issues in different regions without affecting the entire container uniformly.
2Temperature
If heating means are added to control liner temperature, then thermal alignment is improved, but device complexity increases
Solution Approach 1:
The heating means are integrated directly into the container structure itself, combining the heating function with the container's existing framework. This integration approach allows temperature control to be achieved without adding separate, complex heating systems, thereby improving thermal alignment while minimizing increases in device complexity.

AI summary
A container for use in a metal extrusion press comprises a mantle having an elongate body comprising an axial bore, an elongate liner accommodated within the axial bore, the liner comprising a longitudinally extending passage through which a billet is advanced, and a fluid channel in thermal communication with the mantle through which a fluid for cooling the container flows.
