Abstract
The invention discloses the method for producing calcium silicate barium cleansing steel agent with high furnace, comprising the following steps: using ganister, lime rock, barite powder and fluorite as raw materials, adding them into high furnace, smelting, and getting the product. The method has the advantages of simple operation, high output and good economic benefit.
Description
Technical field
The invention belongs to purification of molten steel agent field in the metallurgy industry, relate to a kind of production technique of silicon-calcium-barium steel cleaning agent.
Background technology
Phenomenons such as present steel cleaning agent all is to produce on electric arc furnace, and it is too high that cost appears in the result, yields poorly, and energy dissipation is serious, the inventor has invented the production technique of utilizing the coke production silicon-calcium-barium steel cleaning agent on shaft furnace in this case.
Summary of the invention
The object of the present invention is to provide a kind of production technique of producing silicon-calcium-barium steel cleaning agent on shaft furnace, this explained hereafter is simple to operate, output is big, economic benefit is considerable.
Advantage of the present invention is to add after the coke of employing silica, Wingdale, barite, fluorite and some amount mixes in batches, and key is that charge composition must be accurately.So just can make the consumption of coke minimum.
The object of the present invention is achieved like this: adopting silica, Wingdale, barite, fluorite is raw material, use the coke burning to produce high temperature, at high temperature make Wingdale separate into lime and carbonic acid gas, carbonic acid gas is discharged as gas, utilizes fluorite to make lime, silica, barite generate silicon-calcium-barium steel cleaning agent as fusing assistant.Produce silicon-calcium-barium steel cleaning agent comprise select materials, operations such as batching, molten refining, the cast of coming out of the stove, production technique of the present invention comprises: 1 select materials, 2 batchings, 3 go into stove melting, 4 and come out of the stove and pour into a mould four aspects.
1, select materials: raw material comprises silica, Wingdale, fluorite, barite, coke
Material composition and granularity requirements are as follows:
Silica 99% 〉=SiO
2〉=85%, Wingdale 98% 〉=CaCO
3〉=85%, fluorite 95% 〉=CaF
2〉=70%, coke C
Gu〉=80%, barite BaSO
4〉=85%, it is 20-50mm that all raw materials all require granularity.
2, batching: raw material by proportioning is
Proportioning raw materials is characterized in that silica: Wingdale: fluorite: barite: coke=20: 35: 10: mixing is put in stand-by on one side after 15: 20 proportionings.
3, melting: confected materials dropped into carry out melting in the shaft furnace, treat to add virgin material again after the raw material fusing in the shaft furnace.
4, come out of the stove and burn to annotate: treat after the raw material melting finishes in the shaft furnace stove eye opened liquid in the stove poured in the ingot mould and get final product after the cooling.
Embodiment
Raw material powder is broken into the granularity of 20-50mm, take by weighing 200 kilograms in silica, 350 kilograms in Wingdale, 100 kilograms in fluorite, 150 kilograms in barite, 200 kilograms in coke then, after weighing up it is mixed, add in batches in the shaft furnace and smelt, after melting finishes the stove eye opened silico-calcium liquid in the stove is poured in the ingot mould, cooling back depanning promptly gets silicon-calcium-barium steel cleaning agent.This product its composition after chemically examining is Si 〉=16.25%; Ca 〉=23.46%; Ba 〉=3.56%.
Claims (4)
1. method of producing silicon-calcium-barium steel cleaning agent with shaft furnace comprises and selects materials, prepares burden, goes into the stove melting and technology such as the cast of coming out of the stove.
2. a kind of method of producing silicon-calcium-barium steel cleaning agent with shaft furnace according to claim 1 is characterized in that silica 99% 〉=SiO in the raw material
2〉=85%, Wingdale 98% 〉=CaCO
3〉=85%, fluorite 95% 〉=CaF
2〉=70%, coke C
Gu〉=80%, barite BaSO
4〉=85%.
3. a kind of method of producing silicon-calcium-barium steel cleaning agent with shaft furnace according to claim 1 is characterized in that silica, Wingdale, fluorite, barite, coke proportioning by weight are 20: 35: 10: carry out proportioning at 15: 20.
4. a kind of method of producing silicon-calcium-barium steel cleaning agent with shaft furnace according to claim 1 is characterized in that composition is 23% 〉=Si 〉=13% in the silicon-calcium-barium steel cleaning agent finished product; 33% 〉=Ca 〉=20%; 15% 〉=Ba 〉=3%.
