Abstract
The refractory material for the sliding tap-hole block consists of magnesite and/or magnesia alumina spinel refractory material 90-100 % with the rest being zirconia or titanium oxide refractory material. The sliding tap-hole block of the present invention has excellent mechanical performance, chemical stability, corrosion resistance, metal burn-out resistance and oxidation resistance at high temperature, and when it is used in smelting high-oxygen steel and calcium treated steel, it has long service life, light weight and low cost.
Description
(1) technical field:
The present invention relates to a kind of sliding sprue tile for smelting, particularly a kind of high-oxygen steel and calcium treated steel sliding sprue tile for smelting.
(2) background technology:
The sliding sprue tile for smelting that uses mainly contains Al at present
2O
3-C (as Japanese kokai publication hei 11-36012), MgO-C and ZrO
2Carbon containing refractories such as-C and contain aluminium oxynitride (as Chinese CN85109111A) material.For high-oxygen steel, total oxygen height in the steel, FeO height, carbon containing refractory is inefficient with containing the aluminium oxynitride material thus, it will produce oxidation and cause material loose, be to influence its long-lived major reason, thereby limited carbonaceous material and the application that contains aluminium oxynitride; Al
2O
3Material and zirconia material antagonism FeO aggressiveness also are very poor refractory materialss.For the calcium treated steel that has 20~40ppm free [Ca] in the steel, salic, silicon oxide, mullite material are inefficient, and it will cause damage serious owing to generating eutectic, limit the application of such material; Though zirconia material satisfies the requirement of calcium treated steel, there is big, the expensive problem of weight.
(3) summary of the invention:
The object of the present invention is to provide a kind of high-oxygen steel and calcium treated steel sliding sprue tile for smelting, improve its work-ing life, reduce its cost.
For achieving the above object, the present invention adopts following technical scheme:
A kind of high-oxygen steel and calcium treated steel sliding sprue tile for smelting is characterized in that its refractory materials by weight percentage, consist of: one or both are 90~100% in the refractory materials of magnesia and aluminum-spinel, and surplus is the refractory materials of zirconium white or titanium oxide.
Magnesia is purity greater than 97% magnesia.
Aluminum-spinel is for by weight percentage, and content of magnesia is greater than 28% aluminum-spinel.
By weight percentage, join 0~4% MgCl outward
2
The present invention compared with prior art, have following outstanding feature and remarkable advantage: sliding sprue tile for smelting provided by the invention, contain the magnesia more than 90% and the refractory materials of aluminum-spinel, at high temperature has the favorable mechanical performance, the chemical stability height, corrosion-resistant, and anti-molten metal and resistance of oxidation are strong.Under the high-oxygen steel working conditions, its work-ing life will be longer than carbon containing slide gate nozzle and zirconium white slide gate nozzle.Under the calcium treated steel working conditions, its work-ing life will be longer than salic, silicon oxide, mullite slide gate nozzle; Compare with the zirconium white slide gate nozzle, have in light weight and the low advantage of price.
Compare with traditional carbon containing sliding sprue tile for smelting, this sliding sprue tile for smelting also has following characteristics:
1. do not add carbon raw material such as graphite, carbon black etc. in the batching, free from environmental pollution, workman's working conditions is greatly improved;
2. the oxidation products of carbonaceous material is CO or CO
2, oxidation tail skid short texture forms a large amount of apparent pores, causes molten steel and slag to infiltrate, and finally causes erosion-resisting characteristics to descend.
(4) specific embodiment:
Following table is listed sliding sprue tile for smelting composition (percentage by weight) and the characteristic of 5 embodiment:
