Embodiment 1

[0045] Use 75% of the finished material of waste trench material with a particle size of 8-0mm as the aggregate, add 20% of the finished material fine powder of blast furnace dust collection powder with a particle size of ≤0.044mm, 5% of the first-grade soft clay fine powder with a particle size of ≤0.044mm and 0.02% of the modified additive with a particle size of ≤0.044mm is used as the base material, and 4.3% of the binder industrial syrup solution is added to each base material to obtain the slag ditch ramming material of the present invention.

[0046] In this formula, the added amount of recycled waste refractories and blast furnace dust powder reaches 90%.

[0047] Raw material requirements:

[0048] The particle size of the finished material is less than or equal to 8mm, and the chemical composition is Al 2 o 3 +SiC≥70%, Fe 2 o 3 ≤2.0%.

[0049] The particle size of the finished material of recovered blast furnace dust collection powder is ≤0.044mm, and the chemic...

Abstract

The invention relates to resource regeneration technology and provides a slag channel ramming material produced by utilizing blast furnace waste channel material and blast furnace dust-collected powder, the ingredients thereof are: 70%-80% of skeletal material recycling waste channel material grain finished material, 15%-24% of refinement material recycling blast furnace dust-collected powder finished material and 0.01%-0.05% of modified addition agent, and the left is refinement material grade-one soft clay; the skeletal refinement material forms the base, and 4%-4.5% of bonding agent is added in each base. The production flow thereof includes: (1) waste channel material treatment, (2) blast furnace dust-colleted powder treatment, and (3) slag channel ramming material production. The production flow of the slag channel ramming material includes: (1) adding the recycled waste channel material grain finished material in the blender according to the prescription and stirring; (2) adding some industrial sirup solution and stirring; (3) adding the recycled blast furnace dust-collected powder finished material, the grade-one soft clay and the modified addition agent as well as the left industrial sirup solution and stirring; (4) discharging, measurement and bagging. The invention has better economic benefit and social benefit.

Description

technical field [0001] The invention relates to the recycling technology of waste resources, in particular to the recycling and utilization of waste refractory materials in the iron and steel smelting industry, and specifically refers to the technology of producing slag ditch ramming material by using blast furnace waste ditch material and blast furnace dust collection powder. Background technique [0002] noun terms [0003] Blast furnace trench material: The refractory material used in the trench system of the blast furnace casthouse is collectively referred to as trench material. The ditch system of blast furnace casthouse is mainly divided into main ditch, slag ditch and iron ditch. The molten iron flows into the main ditch from the blast furnace taphole, and through the separation of the slag retaining weir, the pure molten iron flows into the iron ditch, and the slag liquid flows into the slag ditch. [0004] Abandoned blast furnace trench material: refers to the rem...
