Change calcium, iron chloride, sodium chloride, ammonium chloride.Binding agent is the 1.5-2.0% of raw material gross weight with addition of amount.But, this binding agent
Under the metallurgical smelting process condition of high temperature, chloride ion enters flue gas, works the mischief pipeline and fume treatment auxiliary, and uses
This binding agent, chloride ion enters in air with flue gas, also can increase the generation of toxicant two English.
Summary of the invention
It is an object of the present invention to provide a kind of range more extensively, cost is lower and meets the cold consolidation technique of metallurgy powder and makes
By the consolidating agent required and using method, and solve to freeze off the difficult problem that knot pressure ball consolidating agent is chloride.
Realize the object of the invention one freeze off knot ball press technique with high magnesium consolidating agent, including magnesium oxide, calcium oxide, sulphuric acid
Magnesium, silicon dioxide, aluminium sesquioxide and sulfur, in terms of mass parts, each constituent content is as follows:
A kind of high magnesium consolidating agent, in terms of mass parts, each constituent content is as follows:
A kind of high magnesium consolidating agent, in terms of mass parts, each constituent content is as follows:
A kind of high magnesium consolidating agent, in terms of mass parts, each constituent content is as follows:
A kind of high magnesium consolidating agent, in terms of mass parts, each constituent content is as follows:
Magnesium oxide 21.6
Calcium oxide 0.8
Magnesium sulfate 36.9
Silicon dioxide 0.3
The using method of any of the above-described high magnesium consolidating agent, the 2-that the amount of allocating into is material gross mass of described high magnesium consolidating agent
6wt%。
After described material mixes with described high magnesium consolidating agent, control the moisture of mixed material less than 10wt%.
Described material is ion dust mud contaning and iron scale, and wherein said iron scale pulverizing and jevigating to granularity is less than 5mm, contains
Ferrum dirt mud is 1 or more than 1 with the mass ratio of iron scale.
This novel consolidating agent consolidation strength is up to 1000-2000N.It is applicable not only to all kinds of ion dust mud contaning material, the most applicable
In iron scale class bulky grain or the metallurgy powder of cohesiveness difference；And can solve the problem that the two English pollutions that chloride consolidating agent brings are asked
Topic.And this consolidating agent raw material drawing is extensive, cheap, can be with large-scale production and application.
