Abstract

A deoxidizing AlSiMn briquette for smelting alloy steel contains Al (2-50 wt%), Si (5-20), Mn (20-54), C (0-5), S (0-0.1) P (0-0.2), water (0-2) and Fe (rest). It is prepared through proportionally mixing raw materials, adding adhesive, stirring, loading in mould, pressing, demoulding and baking.

Description

Aluminium silicon manganese dioxidation briquette
Technical field
The present invention relates to the aluminium silicon manganese dioxidation briquette that the molten aluminium of acid required behind the reductor of a kind of metallurgical casting steel-making usefulness and the alloy.
Background technology
At present, fast development along with China's Iron And Steel Industry, the steel-making industry develops into the compound aluminium silicon manganese dioxidation of using by the single silicon of tradition, manganese or fine aluminium deoxidation, as Chinese patent disclosed " Al-Si-Mn alloy and manufacture method thereof ", its publication number is the CN1169986C patent, it mainly is made up of the aluminium silicomanganese, wherein also contains carbon, phosphorus, sulphur and unavoidable impurities thereof; Its method is that to add thermogravimetric molten, and silicomanganese is dropped into medium-frequency induction furnace, heats up; The slag making de-carbon; Adding aluminium again adds silicon, stirs evenly, heats up; Last ingot casting, cooling and demolding fast.This Al-Si-Mn alloy has than great, can penetrate the slag liquid level, gos deep into having made full use of valuable element in the molten steel, and impurity such as institute's carbon containing phosphorus, sulphur are decreased.But in the above-mentioned technology,, be to make by the complicated molten casting ingot method of weight as the Al-Si-Mn alloy of reductor and additive, so required complex process, consuming electric power causes the production cost height.
Summary of the invention
The objective of the invention is for addressing the above problem, and provide a kind of in the utilization ratio that guarantees to improve each deoxidant element, the deoxidation products that can satisfy generation be easy to float and the preceding topic got rid of under, the aluminium silicon manganese dioxidation briquette that can reduce production costs again.
For achieving the above object, technical solution of the present invention is finished by following measure: a kind of aluminium silicon manganese dioxidation briquette, comprise aluminium, silicon, manganese and the carbon that contains thereof, sulphur, phosphorus, iron, water, after allotment ratio on request, add caking agent, fully mixing is poured compression moulding in the die forming machine, oven dry removal moisture content into, promptly obtains deoxidation press cake; The mixing raw material that its component and content (for weight percentage) are formed is:
Aluminium 2-50%, silicon 5-20%, manganese 20-54%, carbon≤5
Sulphur≤0.1, phosphorus≤0.25, moisture content≤2, iron surplus.
Component of the present invention and content are formed:
Aluminium 10-40%, silicon 5-15%, manganese 30-50%, carbon≤3.5
Sulphur≤0.05, phosphorus≤0.15, moisture content≤1, iron surplus.
Component of the present invention and content are formed:
Aluminium 18-21%, silicon 11-14%, manganese 44-48%, carbon≤2
Sulphur≤0.05, phosphorus≤0.15, moisture content≤0.5, iron surplus.
Forming method, the step of aluminium silicon manganese dioxidation briquette of the present invention are as follows:
1, takes by weighing raw material by weight percentage, put into sand mill and stir 10 minutes formation mixtures;
2, mixing raw material is joined compression moulding in the mould of shaper;
3, the demoulding is carried out dewatered drying with the mixing raw material briquetting of compression moulding, and it is dried to 180 ℃, naturally cooling, promptly obtains deoxidation press cake.
The present invention is in order to improve aluminum content, improved the deoxidation effect of steel-making, ironmaking, and the composite oxides that the aluminium silicomanganese is generated are easy to come-up, get rid of, and makes molten steel cleaner, also guaranteed in some steel the requirement to sour molten aluminium in the steel simultaneously.In addition, this processing method is simple, and production cost is low, has effectively avoided the high problem of complex process, production cost of prior art casting ingot method.
