Embodiment Construction
[0013] The present invention will be further described below in conjunction with embodiment.
[0014] The chemical composition of the proppant formula of the present invention comprises by weight percentage: 5-45% of high-titanium blast furnace slag, 10-30% of high-alumina brick, 17-77% of bauxite, 4-8% of composite sintered The composite sintering agent includes 0-50% dolomite, 10-75% magnetite and 0-50% kaolin. The high-titanium blast furnace slag can be industrial waste high-titanium blast furnace slag, and the high-alumina brick can be used Recycled high alumina bricks.
[0015] The high-titanium blast furnace slag changes the solid solution structure of the proppant sintered product, and the TiO in the high-titanium blast furnace slag is used to 2 Compatible with Al in high alumina bauxite 2 o 3 and SiO 2 Form solid solutions containing titanium corundum, mullite, etc., on the one hand, it can reduce the heat treatment temperature, on the other hand, it can improve th...
