Technical scheme of the present invention is, a kind of counter weight products is characterized in that, described counter weight products contains slag;
Further, described counter weight products also contains barite and/or iron block.
The counter weight products production method may further comprise the steps:
A, the slag of selecting metallurgy industry to produce;
B, above-mentioned slag is processed into the slag material of different bulk specific gravitys;
C, according to the counterweight requirement, select to have the slag material of suitable bulk specific gravity;
D, adding tackiness agent are fixed, are shaped.
Further, among the step c,, add an amount of barite and/or iron block according to the counterweight requirement.
The invention has the beneficial effects as follows, utilize industrial waste to carry out counterweight filling, cost is low, pollution-free, easy to operate, environmental protection, energy-conservation, the proportion collocation is convenient, packing ratio is great, counterweight filling balance.
Embodiment
Below in conjunction with embodiment, describe technical scheme of the present invention in detail.
The slag that in smelting process, produces (slag), the slag (heavy metal slag) that produces when particularly heavy metal is smelted, the slag, the scum that produce during as steel-making are that the blast furnace mud hole is discharged when smelting, the cooling back produces, and contains partly irregular steel, iron particulate slag.After screening, cleaning, heavy metal slag proportion generally reaches 6.5t/m 3About.Iron of using during smeltings such as lead, tin, alloy or iron ore slagging-off, the high specific gravity slag that produces during deslagging includes a large amount of iron and other hyperbaric material, and after screening, cleaning, proportion generally reaches 6.0～7.0t/m 3, few part is arranged at 5.2t/m 3About, discrete is up to 7.8t/m 3
The present invention is exactly a high specific gravity characteristic of utilizing slag, is applied to counter weight products, with the expensive iron and steel weight material of slag replacement cheaply, thereby produces counter weight products cheaply.
Technical scheme of the present invention is, a kind of counter weight products, and described counter weight products contains slag;
Further, described counter weight products also contains barite and/or iron block;
Preferably, described slag proportion 〉=5t/m 3
Concrete, the weight percent that described slag accounts for counter weight products is: 10%～85%.
More specifically, described counter weight products comprises counterweight filling material and counterweight prefabricated component.
Counter weight products production method of the present invention may further comprise the steps:
A, the slag of selecting metallurgy industry to produce;
B, above-mentioned slag is processed into the slag material of different bulk specific gravitys;
C, according to the counterweight requirement, select to have the slag material of suitable bulk specific gravity;
D, adding tackiness agent are fixed, are shaped;
Further, among the step c,, add an amount of baryta and/or iron block according to the counterweight requirement;
Concrete tackiness agent is a cement;
Preferred scheme is that the suitable slag of selection proportion satisfies the bulk specific gravity of slag material:
The slag material of diameter 2～10cm, bulk specific gravity 4.0t/m 3± 10%;
The slag material of diameter 0.5～2cm, bulk specific gravity 4.2t/m 3± 10%;
The following sand grains of diameter 0.5cm is to powder slag material, bulk specific gravity 3.7t/ ± 10%m 3
Further, the described slag slag of attaching most importance to.
The slag that metallurgy industry produces, the product difference of production, the slag proportion of generation is also different.Even produce identical product, the ore that is used to smelt batch difference, the slag of generation also has different proportion.General as long as slag proportion 〉=5t/m 3, can satisfy common counterweight requirement.In the practice, the slag that produces in the heavy metal smelting process can both meet the demands basically, is the first-selection of weight material.
With the slag of choosing, sieve and wash with screening implement and high-pressure water, remove silt, impurity etc.; Through the slag of screening, cleaning, be processed into the slag material of different bulk specific gravitys.If select suitable slag (the proportion 6.5t/m of proportion 3About), the bulk specific gravity of processing back slag material can satisfy:
The slag material of diameter 2～10cm, bulk specific gravity 4.0t/m 3± 10%;
The slag material of diameter 0.5～2cm, bulk specific gravity 4.2t/m 3± 10%;
The following sand grains of diameter 0.5cm is to powder slag material, bulk specific gravity 3.7t/ ± 10%m 3
General heavy metal slag through screening, cleaning, can both reach above-mentioned bulk specific gravity basically.Select for use the slag material of above-mentioned different diameter to arrange in pairs or groups, bulk specific gravity can also further improve, and can satisfy common counterweight requirement.
In actually operating, can select the slag of different specific weight, carry out the proportion collocation after the integration test.When counterweight filling or making counterweight prefabricated component, add an amount of barite, can further reduce cost.Also can add iron block or barite and mix, carry out the proportion collocation with iron block.Be used for the method that counterweight is loaded about barite, see also the ZL03135476.9 patent.
