Method for producing electro-fused zirconia-corundum ramming material by utilizing waste bricks of glass kiln

Abstract

The invention discloses a method for producing an electro-fused zirconia-corundum ramming material by utilizing waste bricks of a glass kiln, which comprises the following steps: removing large impurities in the waste bricks detached from the glass kiln; grinding the selected waste bricks until the granularity is less than 50mm, removing small particles with the granularity less than 2mm, and maintaining the particle material with the granularity between 2 and 50mm for later use; feeding the particle material obtained in the second step into a furnace, smelting the particle material at the temperature of between 1,700 and 2,100 DEG C for 90 minutes, casting into a mould, and naturally cooling; grinding the cast and cooled solution block again, and screening aggregate with the granularity less than 5mm for later use; and taking 65 parts of the aggregate obtained in the fourth step, 20 parts of bauxite cement, 10 parts of zirconia-corundum powder and 5 parts of white mud, and fully mixing the materials uniformly in a blender mixer to obtain the finished product of the electro-fused zirconia-corundum ramming material. The electro-fused zirconia-corundum ramming material has the advantages of good stability, typical properties better than the traditionally used ramming material, production cost 30 to 40 percent lower, and simple production process.

Description

technical field [0001] The invention relates to a ramming material, in particular to a method for producing fused zirconium corundum ramming material by utilizing waste bricks of a glass kiln. Background technique [0002] The ramming material is a bulk material made of silicon carbide, graphite, and electric calcined anthracite as raw materials, mixed with various ultrafine powder additives, fused cement or composite resin as a binder, and is used to fill furnace body cooling equipment and Filler for masonry gaps or masonry screeds. The ramming material has good chemical stability, erosion resistance, wear resistance, spalling resistance and thermal shock resistance, and is widely used in metallurgy, building materials, non-ferrous metal smelting, chemical industry, machinery and other manufacturing industries.

[0003] After the glass kiln has been used for a certain period of time, some bricks need to be replaced due to damage. The removed waste bricks are generally thrown away by the manufacturer as waste. If this is the case for a long time, the waste will occupy space and pollute the environment. At the same time, some useful components in the waste bricks cannot be removed. use, waste
