Title:
EXOTHERMIC MATERIAL FOR CASTING AND EXOTHERMIC FORMED ARTICLE FOR CASTING
Document Type and Number:
Japanese Patent JP2008000799
Kind Code:
A
Abstract:
To provide an exothermic and heat-insulating material for casting and an exothermic formed article for casting capable of obtaining the exothermic effect equal to or higher than that of a conventional exothermic and heat-insulating material without using any fluoride which has been used for a pro-oxidant.
The exothermic material contains, by weight, 5-40% exothermic aluminum material, 1-30% granular powder and granular magnesium material, and as necessary, at least one of 2-15% binding agent, 0.5-20% fibrous material, and 1-20% expanding agent, and the balance refractory aggregate. The exothermic formed article for casting is formed of the exothermic material.
