DESCRIPTION OF THE INVENTION: TECHNICAL FIELD The present invention relates to a titanium-containing molded body, a method for producing the same, and an application thereof. The invention relates in particular to a titanium-containing molded body, for example in the form of bricks, pellets, or pressed stone, as well as to a method of making the molded article, and its use in metallurgical procedures, in particular for loading Into the primary, secondary and tertiary metallurgical melting furnaces or vessels. The invention also relates to a method for improving the retention of a refractory exterior wall to reduce nitrogen oxides and sulfur content (especially in iron analysis and exhaust gases), and to reduce the melting furnace by using synthetic and/or natural titanium carriers or The vertical channel expands the harmful circulating substances. There is also mentioned a method of using a titanium-containing molded body as a slag forming agent, a slag protecting agent, and an alloying agent. [Prior Art] Due to the increasing demand for environmental protection, when materials are used for smelting (Verhtittung, smelting), manufacturers often have to add cost-cost procedures to reduce environmental pollution, which increases manufacturing costs. Therefore, the economics of a method are affected. So many methods have been developed to achieve this complex solution as economically as possible. In the metal refining day guards, there are also existing methods (such as melting the garbage, bu, one, ... eve from the eve of the eve of the environment). The waste gasification operation of this waste uses metallurgy. Method technology. This has the following advantages: a) to ensure the temperature, so that the mineral and metallic waste components become molten * 5 200844389 and make the organic and inorganic treasures * things one if one does not show the gas In the production produced here and / or in the liquid energy into the P ^ a liquid in the slag slag / ~ Meng Yu is not combined into a separable (eluierbar) way. Here, the fused λλ - ^ - genus acts as a sediment of harmful substances integrated into the program. b) Using the reducing atmosphere, # # & y* ^ a ensures that the oxide is reduced. This is the premise that 幵v becomes a liquid alloy. c) The application of the waste material to the value of sigma and sigma value can be ensured because the remaining waste is low (from the dust, sludge and salt of the raw gas cleaning operation). Since it can be used as a dry or wet granule, it can be recognized as a construction material and can be widely used in the world. Therefore, if it is made or produced, it can be treated in iron filings (Schrotthandel). Or directly reduced in the refiner or foundry (Giej3ereim). In the human-level metallurgy, the alloying agent used can also be used in Ferrotitan, Ferric-Kart (Tirr〇karb〇titan) and aluminum hot process. Titanium and aluminum. These alloying agents, especially iron and titanium, are very expensive. The analysis of iron and titanium shows that it is mainly composed of 20 to 75% by weight or more of Ti, and 2 to 1% by weight or more of Α1+Α12〇3. 'from 0. 2 to 8 wt% or more of Shi Xi, and from 20 to 65 wt% or more of Fe. For example, an iron carbon paper may have the following main composition·· Ti: 30 ~40%; C: 5~8%; Si: 3~4%; Al: 1~2%; Μη: 0.5%. For example, titanium|Lu can have the following composition of main components: 6 200844389

This alloying agent is replaced by a high-priced material to greatly improve the economic efficiency of radiation generation. The main reason for using titanium in modern steel and cast iron is to stabilize the Vostian chromium/nickel/steel to prevent crack formation and to refine the graphite seal in the cast iron. Due to the secondary metallurgical process (which often lasts for more than 2 hours), the slag area of the Pfanne or vessel is heavily loaded by the thermal or kinetic action of the slag. The barrels must be used for early work stoppages and high cost repairs.

Generally, a Kupol furnace is used to make metal. Here, the vertical furnace is supplied with coke (as an energy carrier), as well as materials and additional materials. The materials used are solid pig iron, recycled materials, sheet metal packaging and metal scraps (Schrott), depending on the purpose of the production. In order to adjust the § 丨 content of the iron analysis and the favorable flow properties of the slag, molded bodies made of tantalum carbide, kies and limestone were used as additional materials. To remove the metal, the furnace must be discharged slightly above the bottom, and a suction tube is connected to the discharge port, which has two outlets. Here, the liquid slag is introduced into a trapped valley state via the upper outlet. The iron is forced under the slag through another outlet, for example, into a pre-retaining furnace. The suction absorber can function because there is some overpressure in the vertical furnace. However, melting furnaces or vertical furnaces often reach their limits, so there is still an urgent need to develop new technologies to cope with the application of metallurgical waste. 7 200844389 However, in all the conventional methods used to treat waste, pollution problems caused by metallurgical recycling materials (such as zinc, sodium, potassium, lead, copper, vanadium, etc.) still exist. The more waste you have to deal with, the more the quality of these unwanted items. This is particularly the use of refractory exterior wall and the durability of the aggregate (Haltharkeit) is greatly reduced. ^ ^ ^ ...^八1 mp is used in the kiln of the kiln, which is made of different waste materials, such as iron-containing dust, reducing agent, slag forming agent. As well as binders, the purpose of this technique is to enable the Veriittung process, which is typically performed in blast furnace processes, to be carried out in individual pressed molded bodies themselves. Therefore, dusty iron oxide carriers (which are always reappearing in all refining processes) can be better treated. Without these techniques, the proportion of reusable dust is small, so it is necessary to make another environmental pollution.

This kind of zinc particles (it's a rainbow tube from the go., the negative effect of Xin becomes harmless, and the zinc is intruded from the hole in the hole 8 200844389 due to the low effect of the specific gravity of the assembly of the vertical furnace and is caused there. Destruction. Metals such as sodium and potassium require acid slag to be taken out of the furnace, so it will hinder the desulfurization of iron. The desulfurization operation itself needs to be as alkaline as possible. Some of the opposite requirements greatly hinder the blast furnace program. In addition, the alkali metal shell has a flux () effect on the fireproof outer wall, which has a negative impact on the economy. Some alizarins: copper, chromium, nickel, vanadium are almost completely dissolved in the liquid state. In pig iron, j, they cannot be removed even in the subsequent steelmaking process, and these contents are also reduced as much as possible in the front field (Vorfeld). ^ All vertical furnaces use coke as an energy carrier.

The synthetic raw materials used in the chemical industry use different chemical binders, or form a rechargeable titanium carrier in the sintering process, and fill the various procedures in the secondary gold. To the liquid medium f, such as molten metal or molten. The equipment of the S user can continue to be blown into the equipment, and the synthetic titanium carrier can be blown into the alloy. According to the invention, the synthetic titanium carrier has 45~55%, 80~90%, and 1%% ίπο2 available. When the oxygen content of Tl〇2 is unfavorable (for example, outside the vacuum equipment) , 10 200844389 It is possible to use a synthetic titanium carrier based on TiCN, titanium nitride or titanium carbide, which can be modified according to requirements. If the raw material is in the form of a molded body, it is used for a melting furnace or a vertical furnace. The feeding is advantageous. Thus, for example, a feed of a carbide 形式p〇i furnace (KuP〇ifen) in the form of a brick can be used. According to the prior art, these phantoms can be discarded industrially. Examples of industrial use materials based on the "use of materials" used are coal and charcoal, residues containing niobium carbide, dust from steel and steel mills, and pollution from steel mills and other materials (Gicht) And the steel mill dust and sludge contain a lot of pieces, but if they are filled into the vertical pit furnace in the form of solid blocks, they can only be made of iron. To this end, some methods have been developed to make "so-called agglomerates" from dust-using binders. Prior to the solid pressing process, various waste materials to be disposed of and to be smelted are mixed with a slag forming agent, a binder, and a carbon-based reducing agent. [Embodiment] To manufacture the titanium-containing molded body of the present invention, the titanium-containing material used is remotely removed from the following materials: cuminite, titanium dioxide-rich slag, and synthetic titanium-containing material, or at least two A mixture of these materials. - 成 έ 鈇 鈇 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的The process according to the sulphate process 11 200844389 Titanium dioxide and the titanium dioxide from the process of the gas-cutting process, the intermediate product and the coupling product can be extracted from the Τι〇2 production process in the mash. - Residues in the manufacture of titanium dioxide processes. Here, these materials can be obtained from the sulphur dioxide basket method of sulphur dioxide (Excavation Residues) (Aufschluflrlickstand) and the whitening process of the sapphire method. The remainder of the product; if necessary, the δ hai material is pretreated before use as a stimulant, such as neutralization, cleaning, and/or pre-drying. Residues from chemical workers, such as those containing water from Τι〇2, such as those from DENOX catalysts. - Residues from the production of sulphuric acid, so-called slag (Yang (8)), which are produced when the sulphuric acid salt (ferric sulphate) is decomposed, and contains titanium dioxide in addition to iron oxide. The titanium-containing molded body of the present invention can be produced by mixing and/or adding natural titanium ore. Examples of natural titanium ore are limonite ore and/or Sorell. It is rich in children's slag, and/or synthetic titanium dioxide-containing materials. If necessary, other materials may be added to these titanium-containing materials, such as materials used in industrial waste disposal, or reduced, such as carbon-based, such as residues containing cerium carbide, carbon and carbon sludge, furnaces.

In order to manufacture the titanium-containing molded body of the present invention, before the forming is performed by pressing, pressing, and pressing pellets, the above-mentioned fine particles include titanium. Material plus 12 200844389 A mixture of materials used in, , and granules. The mixture thus obtained was pressed with a binder to the molded body of the invention. The titanium ore used in the manufacture of the titanium-containing molded body of the present invention and the titanium-rich slag containing Ti2 are 15 to 90% by weight, and preferably 25 to 85% by weight (by total titanium content). Calculation). The titanium ore may be used without purification or after removing the miscellaneous shells and removing the ore (gangue) (Gangart) from which the cosolvent is produced. r The synthetic titanium material used for producing the titanium-containing molded body of the present invention contains TiO 2 in an amount of 5 to 10% by weight, and preferably 〇 〇 to 〇〇 〇〇 by weight, particularly preferably 1 〇〇 by weight %. Total titanium content is calculated). In addition, the subject matter of the present invention is as follows: the titanium-containing molded body of the present invention is used to improve the service life of the refractory system, and the titanium-containing molded body of the present invention is used to reduce nitrogen oxides and sulfur, and is included in the present invention. Titanium molded body to reduce the accompanying substances in the oxynitride process, for example, in the melting furnace or vertical path of the primary metallurgical field, and the use of the molded body of the present invention as the (four) protective agent and alloy in summer Agent. The invention can provide: a titanium-containing molded body with a grade of gold private $4 Temple is used for melting or primary, and - human-grade, tertiary metallurgical furnace body, life 3 titanium tantalum body to join the vertical Furnace to improve the service life of the furnace wall ===::=:::=2 13 200844389 • Kind of 3 titanium ^ body to add people in the vertical, furnace and melting furnace, such as primary, and primary metallurgical Furnace body to improve the service life of each refractory exterior wall. When the titania-containing molded body of the present invention is placed in a vertical furnace, the molded body is heated during a metallurgical refining process. The reducing agent contained in the molded body towel reduces the oxidizing component of the vertical channel. This occurs on the iron oxide and the titanium compound previously mixed into the stone material. Here, the reducing agent in the molded body is reduced to a reactive Ti〇2 in the first step in the presence of natural ore in the presence of titanium (for example, limonite (in the form of iron ferric oxide, titanium is present in the form of iron titanate)] Then, the obtained Tl〇2 is finally reduced to co and titanium metal. This reaction is achieved immediately in the case of the synthesis of the carrier, since titanium is mainly present in the form of Ti〇2. The element thus reduced to titanium metal is reacted in the final step into extremely high fire resistant titanium carbide, titanium nitride, and/or titanium carbonitride. Further, a highly refractory compound having aluminum, magnesium, and calcium, such as aluminum titanate, barium titanate, and calcium titanate, is formed. In addition, a titanium-containing metal oxide spinel (Spinelle) is formed. The molded body then reacts & dissolves during the smelting process to form a fine iron slag mixture. Here, the titanium carbide, titanium nitride, titanium carbonitride or titanate metal salt and spinel emulsified therein are deposited where those liquids come into contact with the refractory outer wall. When these ultrafine particles are deposited on the surface to be protected, a very refractory and thick layer is formed which is composed of titanium carbonitride, a metal titanate and a spinel. The deposited layer repairs defective locations as well as defect-free areas to prevent penetration of liquids such as iron or slag, and thus greatly increases the service life, particularly in the interior of the kiln, such as in the discharge channel or suction Inside the rainbow tube structure. 14 200844389 When using the titanium-containing molded body of the present invention as a slag protectant, it is possible to add a titanium carrier (preferably a synthetic titanium carrier) to different secondary and tertiary slags in the iron and steel industry. To reduce or completely prevent rapid wear in the slag area of the ladle. This procedure is accomplished by infusing or filling the liquid system by means of a blown or filled granule (consisting of a synthetic titanium carrier) with slag and/or 35 and/or! Compounds composed of s and/or magnesium form different high-degree sulphuric acid salts. For the use of a metallurgical flushing procedure to cause a large movement of the melt with the metal, the titanate-containing m is in permanent contact with the rapidly worn areas of the slag zone in the tub. Thus, the highly refractory strontium-calcium-magnesium and/or aluminum titanate are deposited in the various contact areas and reduce or prevent the wear of important areas of the ladle. The advantage of this modification of the protective function of the different titanium carrier is that even in the oxidizing system, the refractory wall of the refractory outer wall to be protected by the smelting furnace is due to various titanates or titanium compounds. improve. Unwanted concomitant substances, such as zinc, argon, sodium, potassium, etc., are combined into a titanate metal salt by means of a titanium-containing carrier, and thus can be removed from the vertical furnace in a slag composition. The influence of the catalytic activity of the second emulsified titanium and the tendency of titanium to easily form a carbonitride titanium with nitrogen, in which the generated oxidizing gas can be catalytically reduced to nitrogen and further facilitated formation and high temperature nitriding. Titanium, vaporized carbon titanium and/or titanium oxynitride have the advantage that harmful nitrogen oxides can be removed from the exhaust gases. 15 200844389 In addition, there is a variety of sulfur and titanium in the iron that are subsequently removed from the pit furnace. The natural titanium carrier used is preferably brown mineral and/or slag, and the synthetic titanium-containing carrier used is titanium compound titanium. Further, residues of titanium dioxide obtained by the sulfate method or according to the present invention may be used. It is also possible, depending on the invention, to use a catalyst such as from a DENOX plant or to utilize it.
