Abstract
The invention discloses a smelting silicon aluminum calcium barium alloy method, this method take the silica, the lime, the barite, the steel filings and the few carbon reducing agent as a raw material, carries on the allocated proportion according to the certain proportion, joins the ore hot stove in turn, this method smelting silicon aluminum calcium barium alloy output high, the electricity consumes, the economic efficiency lowly considerable, the operation is simpler.
Description
Technical field
The invention belongs to deoxidation in the metallurgy industry, sweetening agent production field, relate to a kind of production method of Si-Al-Ca-Ba iron alloy.
Background technology
Silico-calcium barium ferroaluminium is as deoxidation in the steel-making, sweetening agent extensively is employed, but producing the Si-Al-Ca-Ba iron alloy mostly is to adopt " remelting process " or " dashing the method for converting " to carry out the production of Si-Al-Ca-Ba iron alloy, promptly ferrosilicon (or industrial silicon), silicocalcium Si-Ba alloy and electrolytic aluminum in induction furnace by the alloy requirement become fractional melting to join to form or when smelting calsibar alloy, adopt and add aluminium ingot in the hot metal ladle towards converting into the Si-Al-Ca-Ba iron alloy, these two kinds of methods all exist the product percentage of product low, quality problems such as alloying constituent is inhomogeneous, simultaneously, the production cost height has influenced the widespread use of novel deoxidizer for use in iron and steel enterprise again.For this reason, that the inventor utilizes on the basis of original production silicon aluminum calcium barium alloy is siliceous, the ore of aluminium, calcium, barium, on the hot stove in 3600KVA ore deposit with the direct original production Si-Al-Ca-Ba iron alloy also of coke.
Summary of the invention
The purpose of this invention is to provide a kind of production method of producing silicon aluminum calcium barium alloy on the hot stove in 3600KVA ore deposit, this method operation is simple, and cost reduces, the output height.
Advantage of the present invention is to adopt the multiple silica that is easy to look for, lime, barite, aluminium vanadine, coal, iron filings as raw material, carries out proportioning by a certain percentage, mixes the back gradation and adds in the hot stove in ore deposit, reduces power consumption, improves output, quality.
The object of the present invention is achieved like this: adopting silica, lime, barite, aluminium vanadine, coal etc. with the hot stove in 3600KVA ore deposit be raw material, in proportion proportioning evenly after, drop in the hot stove in ore deposit in batches, at high temperature make its production Si-Al-Ca-Ba iron alloy.Produce silicon aluminum calcium barium alloy comprise select materials, operations such as batching, melting, tapping casting, chemical analysis, finishing warehouse-in.The total proportioning of raw material is a silica: lime: barite: aluminium vanadine: coal: iron filings=29: 8: 9: 22: 25: 7.
Production method of the present invention comprises: 1 select materials, 2 batchings, 3 meltings, four aspects of 4 tapping casting.
1. select materials: raw material comprises silica, lime, barite, aluminium vanadine, coal, iron filings
Material composition and granularity requirements are as follows:
| Material name | Composition requires (%) | Granularity requirements |
| Silica | ????SiO 2≥90％ | ????50-100mm |
| Lime | ????CaO≥85％ | ????50-100mm |
| Barite | ????BaSO 4≥80％ | ????50-150mm |
| The aluminium vanadine | ????Al 2O 3≥55％、SiO 2≥25％ | ????50-100mm |
| Coal | ????C Gu≥80％ | ????0-15mm |
| Iron filings | ????Fe≥85％ | ????15-500mm |
2. prepare burden: proportioning raw materials is carried out proportioning by following weight percent and is:
Silica: lime: barite: aluminium vanadine: coal: iron filings=29: 8: 9: 22: 25: 7: mixing is put in stand-by on one side after the proportioning.
3. melting: confected materials put in the hot stove in ore deposit carry out melting, added a defective material in per 20 minutes, come out of the stove, went out a stove in general 2-3 hour according to the working of a furnace.
4. the cast of coming out of the stove: after treating that melting finishes, the stove eye opened alloy liquid in the stove is poured in the ingot mould.
Embodiment
Raw material crushing is become desired specification, take by weighing 295 kilograms in silica, 82 jin in lime, 92 kilograms in barite, 224 kilograms of aluminium vanadine, 255 kilograms in coal, 72 kilograms of iron filings then, after weighing is good that its proportioning is even, drop in batches in the hot stove in ore deposit and smelt, after melting finishes the stove eye opened silico-calcium barium aluminium alloy liquid in the stove is poured in the ingot mould, after the cooling depanning promptly obtained silico-calcium barium aluminium alloy product.This product its composition after chemically examining is Si42.30%, Ca6.80%, Ba9.56%, Al13.3%.
