Definitions

  • a first purpose of the invention is to provide a process for elaborating steel from cast iron and metal alloys in which the speed of action of finishing or addition products injected into the molten metal mass is increased.
  • Another purpose of the invention is to facilitate the action of the finishing products which act as reaction or reducing agents, or as composition elements.
  • Another purpose of the invention is to allow the treatment of liquid baths of ferrous metals, steel, cast iron and alloys by using a gas to blow finishing products or addition materials in powder form beneath the surface of the liquid metals so that at the moment of dispersing the products in the liquid mass there is intimate internal contact, thereby increasing the speed of action on the liquid metal of the products injected.
  • Another purpose of the invention is to improve the productivity of melting equipment used for producing steel, cast iron and alloys and, as a result, to make the production more economical.
  • FIGURE 1 shows a sectional view of the apparatus
  • FIGURE 2 is a sectional View taken along line 2-2 of FIG. 1 showing the feeder for supplying the central column;
  • FIGURE 3 is a sectional view along line 33 of FIG. 1 showing the discharge chamber
  • FIGURE 4 is a fragmentary sectional view of another embodiment of a discharge chamber for use in the apparatus of FIGUREd;
  • FIGURE 5 is a partial sectional view of another embodiment of the apparatus as characterized by the features of the invention and having two discharge chambers.
  • metallurgical operations are carried out which consist of introducing finishing products under the surface of the liquid bath by means of the apparatus shown in the abovementioned figures and by means of a gas carrying either all or part of the products suitable for these operations.
  • This method is based on the most rapid means for economically elfecting various metallurgical operations in liquid baths by means of materials which are currently utilized in iron smelting.
  • FIGURE 1 is an example.
  • the equipment essentially consists of a tank 1 formed of a steel cylinder whose lower part is formed by a conical portion 2 which is funnel-shaped.
  • the cylinder 1 is closed at the top by a steel sheet 3 whose rigidity is strengthened by ribs 4.
  • This sheet 3 defines aperture which is used for filling the tank. This aperture is closed by a cover 5 held in position by a screw actuated by a hand-wheel which exerts a pressure in order to obtain the seal-tightness inside the tank.
  • the screw exerting a central pressure controlled by the hand-wheel 7 is mounted on a strap 6 articulated around a hinge 8 to enable opening.
  • a locking system 9 enables the strap to be hooked on its opposite side.
  • Two hoisting rings 10 enable this apparatus to be transported by an overhead or ordinary crane, etc.
  • the safety of the apparatus is ensured by a safety valve 11 mounted on the sheet 3, while a rapid escape diaphragm 12 and a value regulated with a permanent leak 13 are mounted in the removable cover 5.
  • catches 2 are provided at various heights for maintaining cones for distributing the material.
  • the fluidification, injection and atomization of the materials are eifected by means of compressed air or an inert gas under pressure. These gases are conveyed to the interior of the apparatus through piping 14 feeding a collector 15. A circular ramp is connected to this collector 15 placed inside the apparatus on which pipes 17 and 18 are mounted branching off at various heights inside the cylinder 1.
  • This central column comprises, on its lateral surface, a series of apertures enabling the passage of the gas under pressure, the upper and lower apertures of the piping 19 being closed.
  • the column 19 is made up of elements inserted in each other, each of the elements comprising a distributing cone for materials Whose free end rests on the catches 2 of the conical cylinder 2.
  • T hese'elernents 20, 21 and 22 can be easily removed through the top movable part of the apparatus.
  • a pneumatic vibrator 23 is placed at the base of the apparatus and ensures the regular descent of materials into the mixing chamber. This pneumatic vibrator is fed through piping 36 and 37 coming from the collector 15.
  • the injecting member itself consists of a chamber 24 made in two parts placed at the base of the conical portion 2. One of the two parts is integral with'said conical portion and the other is bolted on to the fixed part. Inside this chamber, the opening enabling the delivery of materials is regulated by a valve plate 25, itself controlled by a hand-wheel 26 acting through a rod.
  • the rod of the hand-wheel carries a deflecting screen with holes 21 sloping at 45.
  • a detachable injector 28 is connected and supplied with gas through the compressed air inlet pipe 38 coming from the collector 15.
  • This detachable injector 28 comprises an injection head 29 with double apertures whose diameter varies according to the pressure required for atomizing the products (FIGURE 3). This injector ensures the passage of the product through the deflecting screen 27 and sends it towards the chamber 39 for putting into suspension (FIGURE 1).
  • the mixture thus pulverized passes into an atomizing chamber 31 where another gas under pressure introduced through the opening 32 speeds up the discharge of the products towards the injecting jet 34.
  • a supplementary atomizer 33 is provided on the sleeve of the injecting jet and enables the mixture to be regulated and prevents any drop in pressure in the pipes connecting the apparatus to the injecting jet.
  • a gate 35 controls the opening of the inlet of gas under pressure from the main pipe 14 towards the collector 15.
  • Two manometers 4t and 4-1 enable the pressure to be known at any moment that exists in the inlet pipe and the inside of the tank.
  • a supplementary inert gas inlet can be put into operation on all the circuits by means of a gate i2, after the to closing of the compressed air intake in the tank by the gate 35.
  • the apparatus thus formed is mounted on a frame 43, which latter comprises rolling means such as rollers 44 or similar devices. This arrangement enables the apparatus to be put into operation at any spot in equipments.
  • the mixing chamber may comprise a closing device whose control takes place horizontally, contrary to the preceding system Whose control takes place vertically.
  • a rod actuated by a hand-wheel 26 which closes the aperture at the base of the tank by means of a valve plate 25'.
  • This arrangement is often employed when apparatuses are required with several outlets.
  • Various types of apparatuses are made according to the same arrangements, and an apparatus can be equipped with single tank as shown in FlGURE l, or an apparatus may be provided with two tanks. Apparatuses can also be made with two asymmetrical tanks, of which the second is provided with a large capacity and has one or two outlets for discharging highly concentrated products in the transporting gas.
  • FIGURE 5 is an example of a two-outlet apparatus, and there are two inlet chambers 24 each comprising a double aperture injection sheet 29 and a regulating system with hand-wheel 25. These hand-wheels actuate the valve plates 25 to enable the eventual closing of the outlet of one or more products.
  • an apparatus may be obtained fitted with two asymmetrical tanks of which the second one has a greater capacity and one of the pipes fitted with different systems for regulat ing distribution.
  • This alternative is obtained by varying the section of the mixing chamber and the diameter of the interchangeable injector placed at the inlet of each chamber, so as to convey products of various densities and size distribution with a controlled time and delivery.
  • apparatuses can be ob-' tained fitted with three tanks that can have a very large capacity, 1600 liters, for instance.
  • This process enables a maximum efiiciency to be obtained by utilizing the maximum of iron ore, low content coppe pyrites, mill-scale, etc., which cost less than scrap iron, cast iron or liquid metal for running in duplex.
  • ron ore is currently employed for the oxidizing stage during which it is sought to eliminate certain impurities oi: the initial charge.
  • This process is thus based on the charging of iron ore necessary for oxidizing carbon, phosphorous, and if required, other impurities for adding oxidizing slags, the removal or" these sings, the refining of the liquid metal by means of new slags, neutral or reducing, the eventual carburization, the addition of deoxidizing alloys and composition, and finally, pouring.
  • T he process of the invention enables the initial metal charge (cast iron, scrap or liquid metal coming from other molten metal) by a corresponding quantity of iron containing iron ore, pyrite ashes, mill-scale or other ferrous products, this process enabling operations to be conducted in one movement and to inject by blowing under the surface of the bath, a certain quantity of products suitable for the metallurgical necessities sought, at the rate, and with the kind of mel ing apparatus em loyed.
  • the productivity of an electric furnace essentially depends on its melting speed, the duration of the refining period and that of deoxidization.
  • the electric furnace charged with part of its initial charge rapidly melts the solid charge put in, so that at the end of sme ing, the liquid metal treated by injection technique gives a liquid bath of high carbon content and suitable chemical composition for receiving the charge of iron ore or pyrite ashes.
  • the quantity of powdered materials to be injected must not exceed a certain dose, for beyond a reasonable proportion, the duration of injection and refining is prolonged, thus cancelling out the gain in smelting.
  • the refining of the liquid carburized bath is ensured by pouring into the electric furnace the balance of tie metal charge tormedby pyrite ashes, iron ore, mill-scale, etc. plus carbon, plus CaO and melting, pro-heated and partially pre-reduccd in the rotary furnace.
  • This process by injection also enables, in electric furnaces and even in Martin furnaces, treated ferrous products to be utilized.
  • the limits may be di .iinished'that are allowed by the shade and quality of the steel to be obtained, up to a given extent, of the quantity of cast iron put in, and to replace the tonnage extracted from tie cast iron by ferrous moduluses.
  • the present invention which has the purpose of introducing into a molten metal mass, reaction and combination agents, enables the following advantages to be obtained:
  • the reducing components of the recarburizing mixture possess an afiinity for oxygen that is greater than that of iron; this means a rise in temperature due to the exothermic action caused by the action of the combined products that are particularly absorptive of the oxygen large quantities of p of the bath and the air. With the rise in temperature of the bath, the rate of carbon yield is very high.
  • Recarburizing injections improve heat exchanges enabling a distinct reduction to be obtained in the consumption of electric power of electrodes, refractories, etc. of calories (gas fuel oil) in the case of the Martin and rotary furnaces.
  • the process consists of causing to pass into a liquid bath, by means of the above-mentioned apparatus, fine oxidizing elements by means of a gas conveying compressed air with or without the addition of gaseous oxygen.
  • the oxygen of the air and oxidizing elements and possibly the addition of gaseous oxygen burn the materials to be eliminated, silicon, carbon, phosphorus, and this combustion is accompanied by a rise in temperature. According to the composition of the metal and the scoria, the speed of decarburization rises in more or less considerable proportions.
  • the finishing alloy has the purpose of:
  • the process consists of introducing into the liquid bath various deoxidizing alloys together with desulphurizing products in the form of powders, either into the furnace or in the ladle, by means of a fluidifying appliance and by means of a conveying gas.
  • the heat-producing power of the reducing elements appears to be very interesting, for at each temperature, there exists a dividing coeificient with the combination element dissolved in the liquid metal.
  • Apparatus for mixing and fluidizing a solid powdered material with a gaseous fluid and transporting the fluidized mixture into a liquid bath comprising hopper means for containing a quantity of said powdered materials, said hopper means including a frusto-conical lower portion having an outlet at the lower end thereof, conduit means in said hopper means extending downwardly into Said frusto-conical portion including a central duct in axial alignment therewith having a plurality of openings spaced along a substantial length thereof for directing a flow of said fluid radially outward to fiuidize and mix said powdered material, a plurality of spaced apart distributing cone elements formed around said central duct extending upwardly and inwardly from said frustoconical lower portion, injection chamber means below said hopper means having an inlet in communication with the outlet of said hopper means and an outlet, valve means cooperating with the inlet of said chamber means for controlling the fiow of fluidized materials from said hopper means, injector means extending into said
