[0017] The preparation method of this slagging agent specifically comprises the steps:
[0018] (1) Dry the fluoride salt residue and calcium fluoride of the Al-5Ti-1B master alloy prepared by the fluoride salt reaction method at 200-300° C. for 2-5 hours;
[0019] (2) Fully mix the above-mentioned fluorine salt with dried potassium feldspar and aluminum ash to obtain an aluminum alloy slag removing agent.
[0020] In the present invention, the method for preparing the Al-5Ti-1B master alloy by the fluoride salt reaction method is referred to Chinese Patent Publication No.: CN107034374A, and the Al-5Ti-1B master alloy is obtained by chemical reaction of the fluoride salt mixture and the aluminum melt; wherein: according to In terms of the weight percent of each component in the fluoride salt mixture to the aluminum melt, the composition of the fluoride salt mixture is: K 2 TiF 6 22-30%, KBF 4 10-14%, CaF 2 0.01~0.114%, MgF 2 It is 0.01-0.114%, and the fluorine salt residu...
Embodiment 1
[0023] In this embodiment, the environmentally friendly, recyclable aluminum alloy slag removing agent and its preparation method are as follows:
[0024] (1) Prepare materials according to the following components by weight: 70% fluorine salt residue+15% aluminum ash+1% potassium feldspar+14% calcium fluoride prepared from Al-5Ti-1B master alloy by fluoride salt reaction method. Among them, the particle sizes of the fluorine salt residue, aluminum ash, potassium feldspar and calcium fluoride of the Al-5Ti-1B master alloy prepared by the raw material fluoride salt reaction method are 0.05~0.08mm, 0.08~0.1mm, 0.04~0.07mm and 0.04~ 0.07mm.
[0025] (2) After the fluoride salt residue and calcium fluoride of the Al-5Ti-1B master alloy prepared by the fluoride salt reaction method in step (1) are dried at a constant temperature of 200 ° C for 4 hours, they are fully mixed with dried potassium feldspar and aluminum ash, namely An aluminum alloy slag remover is obtained.
Embodiment 2
[0029] In this embodiment, the environmentally friendly, recyclable aluminum alloy slag removing agent and its preparation method are as follows:
[0030] (1) Prepare materials according to the following components by weight: 80% fluorine salt residue+10% aluminum ash+3% potassium feldspar+7% calcium fluoride prepared from Al-5Ti-1B master alloy by 80% fluoride salt reaction method. Among them, the particle sizes of the fluorine salt residue, aluminum ash, potassium feldspar and calcium fluoride of the Al-5Ti-1B master alloy prepared by the raw material fluoride salt reaction method are 0.05~0.08mm, 0.08~0.1mm, 0.04~0.07mm and 0.04~ 0.07mm.
[0031] (2) After drying the fluoride salt residue and calcium fluoride of the Al-5Ti-1B master alloy prepared by the fluoride salt reaction method in step (1) at a constant temperature of 250 ° C for 3 hours, they are fully mixed with dried potassium feldspar and aluminum ash, namely An aluminum alloy slag remover is obtained.
