Thermal and mechanical behavior of copper molds during thin-slab casting (II): Mold crack formation

From: Metallurgical and Materials Transactions | Date: June 1, 2002| Author: Samarasekera, Indira V; Thomas, Brian G; Yoon, U Sok; Park, Joon Kil | Copyright information

The formation of cracks in a funnel mold of thin-slab casting is investigated using metallographic studies and mathematical models. In Part II of this two-part article on thin-slab casting molds, short longitudinal cracks near the meniscus region of a thin-slab funnel mold are studied metallurgically. X-ray analyses revealed the formation of Cu-Zn brass on the copper matrix at high temperature where the crack initiated. Heat-transfer and thermal-elastic-viscoplastic stress models described in...

Tips on good refractory practice for aluminum - melting furnaces. (Ceramics & Refractories/Insulation).
Industrial Heating ; Refractories in contact with molten aluminum must resist aluminum penetration, chemical reaction with the aluminum, mechanical abuse, thermal spalling and attack by fluxes. Good refractory practice can help minimize these problems. Melting aluminum in a reverberatory furnace involves heating the
Bubble alumina retains integrity at high temperatures
Advanced Ceramics Report ; Vulcan Refractories has launched a new group of 'Vulcasil' materials designed to withstand the high temperatures and provide the thermal shock resistance demanded by specialist furnace and kiln users. The high grade bubble alumina, 'Vulcasil HRP 27', 'VR 271' and 'VR 251' materials provide the high
Using microtherm microporous insulation in smelter applications
JOM ; Microtherm is effective in reducing shell temperatures in confined spaces where compression is severe and much insulation is required. This material can prove beneficial for applications such as cement and lime rotary kiln transition and hot zones; copper converters and anode furnaces; steel and
Thermal and mechanical behavior of copper molds during thin-slab casting (I): Plant trial and mathematical modeling
Metallurgical and Materials Transactions ; Three-dimensional (3-D) finite-element thermal-stress models have been developed to predict temperature, distortion, and residual stress in the mold of continuous casters of thin steel slabs, comparing both funnel-shaped and parallel molds. The mold shape and high casting speed leads to higher mold
