Investment proposal for the creation of a steel-making production

The goal of our new project is to create an environmentally friendly and most efficient steelmaking production. To achieve these high criteria, we will use our own, latest technologies, including ShPR. This will significantly reduce the cost of the products obtained, as well as make the production of metal as environmentally friendly as possible. At this time, it is planned to create a mini-plant with a capacity of 39 - 40 thousand tons of metal per year. Steel smelting will be carried out using two 5-ton induction furnaces with installed melt processing devices manufactured using the ShPR technology.

The first such production, we plan to open in Hungary, and focus on the smelting of reinforcing steel 25G2S and stainless steel 08X18H10T (AiSi 321).

In the future, we plan to implement similar projects at the request of investors - engineering, commissioning, start-up, technical and licensing support for production.

As a result of market research of steelmaking equipment manufacturers, we came to the conclusion that “Termolit” Ukraine is the best in all respects. In addition to the excellent technical level and compliance with all modern requirements, the company assumes the transportation, installation, adjustment and annual warranty service of its units. In addition, all accessories for induction furnaces also supplies and services "Termolit".

All the strong performance, the proposed production is only possible thanks to the introduction of the steel production process, ShPR technology. Therefore, Swiss Steel Fire undertakes the licensing, commissioning and support of equipment manufactured using this technology. In fact, we offer a turnkey ready-made metallurgical production. Due to the versatility of the ShPR technology, the owner of such a plant will be able to produce any steel grade and be competitive in the market under any circumstances.

Commercial offer for the supply of ShPR units

Our company has exclusive rights to use and apply energy-saving technology of daisy-chain blow-down of metal melt with an inert gas in small-bubble mode through the blow-down blocks. National and international patents protect this technology. There is no analogue in the world. It allows increasing the mass exchange between gas and melt, to enlarge the efficiency of deletion non-metallic inclusions and to decrease the saturation of gas in the melt, to increase an efficiency of treatments of molten metal and to decrease its base cost.

Sectional construction of our blocks allows to set their working surface that equals from 2 to 70% from total area of the bottom of metal container (current blow-down devices don’t even cover 0.5% of area of the bottom).That’s why it is possible to apply them for any metal containers with different kind of lining.

Our technology allows:

cut energy resources expenses (5-20%) during alloying the steel in the ladle furnace devices or in electric arc furnaces;
increase metallic yield (1-3%)by reducing quantity of non-metallic inclusions with different chemical composition;
make temperature uniformity of molten metal;
enhance the molten melt flow that allows decreasing temperature of pouring (10-20 C) and to get fine-grained structure ingots, thereby reduce existing types of defects;
depending on steel grade, to reduce melting loss of powder additives and deoxidizing (more than 10%), thereby improving the efficiency of used desulfurizer and dephosphorizer;
eliminate metal turbulence in industrial ladles;
remove hydrogen and other gases from metal melt more effective than other methods known today.

Swiss Steel Fire always takes care of its customers and does everything to be open and efficient. You can ask us any questions via the feedback form or by e-mail at office@ssf-shz.com. You can also download the price list with our products.

The device for supplying gas into a metallurgical vessel

Currently used ladle devices in the steel factories for attachment of the ladle gas system, are very unreliable, or require human intervention while connecting and disconnecting. From the point of view of safety requirements, the disconnecting is particularly unacceptable when metallurgical vessel is filled with liquid metal.

We propose an automatic connecting device. This device works only when the gas supply to blowing device and independently disconnected after completion of gas supply. This device has the following advantages:

hid from the splatter of metal and slag;
while splash and slag of the molten metal from the ladle , device screened by structural ladle element (connecting pin is located at a steel beam carts or other devices and construction );
joining the device is going on independently offline;
connection to the gas system takes place to ladle car or stand , therefore, the flexible hose stays in a more comfortable environment , the device is safe and is always in operating state;
easy to maintain, available for repair, replacement devices for prevention goes on quickly and does not require special measures and adaptations.

The method of implementation ultra-dispersed powders ( a processing reagent) into the melt

The lack of reliable ways of putting dispersed powders into the melt hampers in effective use of them. The earliest methods of input of fine dispersed powders were consisted of entering them with the gas through a false lock installed in the ladle, or a special stand lined with submerged lance.

The disadvantage of submerged lance is its low resistance of castables due to heavy dilution of their high-speed streams of molten metal, and the high cost of high-quality refractory of lance.

Here it is necessary to include the cost of manufacturing a metal stand for blowing with argon, the need for staff, energy costs.

When entering the powder through the lance nozzle, due to the large and irregular bubble, breakers are formed on the metal surface and a large portion of the predicted fine powders are ejected in large bubbles mode, and at break of slag, covering it develops the process of a secondary oxidation.

In terms of hydrodynamics and comfortable service, the installation of blowing device in the bottom of ladle is technological. In this case, gas-powder flow, rising from the bottom surface, interacts with benthic volumes of liquid metal more effectively.

Using the blow-down tube, an extra blowing during adjusting the chemical composition of the molten metal is impossible. Furthermore, this method is effective only for coarse dispersed powders. Fine dispersed powder, and especially ultra-dispersed powder is distributed throughout the whole volume of the bubble and is carried into the environment.

Consequently, all of the powder fed, only coarse dispersed powder moves to the melt. In this case, to predict in advance the power consumption and assimilation of injected powder is extremely difficult.

We have developed an installation for the continuous input of ultra-dispersed powders with an activated surface and the way of dosed injection with a special batcher with an inert gas in the mode of ShPR. The proposed technology provides increased predictability and efficiency of input of ultra-dispersed powders, their uniform distribution within the melt, increasing the time of mass-transfer processes. Small, but not merging bubbles allow increasing maximally the rate of transition of the powder into the melt. Filing powder through the stitch capillaries allowed increasing the area of mass transfer hundreds of times.
