PROCESS FOR PREPARING ALUMINUM-TITANIUM-BORON REFINER PLATE AND STRIP
Document Type and Number:
WIPO Patent Application WO/2021/007893
Kind Code:
A1
Abstract:
Disclosed is a process for preparing an aluminum-titanium-boron refiner plate and strip, comprising the preparation-cast rolling-crimping of a refiner alloy melt, wherein a method for preparing the refiner alloy melt comprises the following steps: respectively preparing aluminum-titanium and aluminum-boron intermediate alloy melts, and controlling the temperature of the intermediate alloy melts at 750-900ºC; and mixing and reacting the aluminum-titanium and aluminum-boron intermediate alloy melts, and keeping the temperature at 750-900ºC for 10-60 minutes, and then reducing the temperature of the mixed melt to 710-750ºC. The process solves the problem of the uneven distribution, small quantity, and larger size of TiAl3 and TiB2 particles in the aluminum-titanium-boron refiner, and improves the refining efficiency thereof.
