Abstract

A furnace cleanser for aluminum is formed by mixing main materials with auxiliary materials, and the main materials comprise 40-80wt% of an aluminum-containing material, 10-30wt% of quartz sand, and the balance carbon-containing material; and the auxiliary materials comprise a high temperature bonding agent having a weight accounting for 1-8% of the weight of the main materials, cellulose having a weight accounting for 1-6% of the weight of the main materials, and an antifoaming agent having a weight accounting for 0.1-1% of the weight of the main materials. In the invention, the main materials are hardened in high temperature environment with the aid of the auxiliary materials comprising the high temperature bonding agent and cellulose in order to form a protection layer separating molten aluminum from the inner wall of the furnace, and a filter cakes on the protection layer in order to effectively prevent the erosion of the molten aluminum to the body of the furnace and the damages of molten aluminum caking on the inner wall of the furnace body to the wall of the furnace; and the oxidation of the carbon-containing material at a high temperature makes the protection layer formed by the cleanser unstably bonded with the inner wall of the furnace body, so the protection layer and aluminum slag adhered to the protection layer can be easily removed.

Description

technical field [0001] The invention relates to an aluminum liquid containing furnace used in the fields of aluminum casting and aluminum remelting casting, in particular to a furnace cleaning material for aluminum. Background technique [0002] In aluminum casting, aluminum remelting casting, aluminum deep processing and other fields that need to melt aluminum before processing or production, in these fields, after the aluminum is melted, the inner wall of the furnace will continue to slag, resulting in the mixing of aluminum into the furnace The volume keeps getting smaller, and a 40-ton furnace can only hold 10 tons of aluminum or less, which will result in less aluminum input into each furnace and seriously affect the output of each furnace. It is necessary to use multiple personnel or cleaning equipment for strong cleaning to clean it. Sometimes the inner wall of the equipment furnace is cleaned, and the inner wall is also damaged, which affects the service life (the li...
