Technological Materials:


Graphite electrodes with nipple (various sizes)

 

Графитированные электроды с ниппелями

Graphite electrodes are used in arc steel-smelting and ore-thermal furnaces for smelting high-quality alloyed and low- carbon steels, ferrous fusions and special fusions.
The advantages of graphite electrodes are: low electrical resistance; high thermal stability (resistance to thermal shock); low ash content in the electrode, which affects the quality of metal fused. We deliver high-quality graphite electrodes for electric arc furnaces of alternative current (AC)  and direct current (DC) with diverse power supply: RP - Standard Power, HP - High Power, UHP - Ultra High Power, with a diameter from 150 to 700 mm, in accordance with international standards of quality.
On the both ends of electrode there are two niduses with cylindrical or conical thread for screwing the nipple. Nipple is required to accumulation of the electrode as it is expensed in the process of steelmaking. Each electrode is equipped with nipple. Upon the request of the customer's nipples can be supplied separately from the electrodes or in addition to the kit.
 The electrodes 250 mm and more and nipples to them are made with tapered threads, 200 mm and less - after consultation with the consumer - with conical, trapezoidal cylindrical or metric threads.


Graphite blocks

 

Графитовые блоки

The graphite blocks are manufactured in extruded or molded form. Granulometric composition, material properties, specifications, technical characteristics and manufacturing process are carefully monitored.
Graphite blocks and rods are used in many types of products and have various application possibilities. For example, in the production of elements of power supply, electromotive brushes, generator brushes, burning furnaces; in metallurgy and production of semiconductors, aerospace, chemical, energy, nuclear, glass industry, and etc.
Delivery is made from the European Union, Russia and China.

 


Refractory products


Огнеупорная продукцияRefractory goods - are materials that are made on the basis of mineral raw materials. Refractory products are characterized by their ability to maintain their functional properties in various conditions applying high temperatures. They are used in metallurgical processes (melting, burning, evaporation, distillation, etc.), construction of high-temperature furnaces and units (reactors, engines, structural elements, etc.). Refractory materials are divided into shaped and unshaped, and divided by several characteristics: composition, degree of fire resistance, size, shape, and area of appliance. They are classified according to sizes and shapes: straight and tapered medium format, small-format and large-format; simple, complex and ultra complex, maxi-shuttle - over 60 kg, non-standard - tubes, melting pots, etc.
 Most frequently used type of refractory products is refractory bricks - straight, face, finned surface, trapezoidal, etc. In order to stow the refractory products refractory powders (mortars, chamotte clay, mullite mixture, etc.) are used.

 

Titanium Sheets

 

Титановые листыTitanium sheets have non-magnetic properties, which led to its widespread use in aerospace and aviation. Chemical equipment, ship hulls, heat exchangers, offshore platforms, and elements of the carcass and revetment of modern buildings are also made from this material.
Titanium sheets can be divided by quality of garniture into:
V - high revetment
P - improved revetment
Normal revetment - no symbol.
Titanium Sheet, can be divided depending on the deviation from the flatness into:
U - advanced flatness
Normal flatness - no symbol.
The size of the titanium sheet (mm) depending on the titanium alloy or titanium grade should be:
1. Titanium sheets with a thickness of 0.3-0.4 and 0.4-1.2 with a width of 400-600, 600, and a length of 1250-2000, 1250-2000, respectively;

Viniplast products

 


Винипластовая продукцияViniplast is polymeric product, which is obtained on basis of polyvinyl chloride (PVC) and post chlorinated polyvinyl chloride with the addition of modifiers and fillers. This material is used in the manufacture of pipes, window and door profiles, revetment elements, chemical equipment, protective enclosures, containers and other products. If during storage and application of viniplast temperature schedule is properly maintained, then it is completely harmless, because it does not emit into the atmosphere any dangerous substances and is not explosive.
High-quality viniplast sheet has a flat rectangular shape with no bumps and impurities. Available in the following grades: Sheets of thickness to 40 mm, made by pressing (VN), sheet thickness to10 mm, obtained by extrusion (VNE), and decorative sheets 1.5-3.0 mm (VD), in production of which may both technologies can be used. The first two grades of viniplast - are non-transparent sheet that can be painted or not painted. In comparison with metals, sheet viniplast is lightweight and has a low rate of deterioration that provides a long-lasting life of structural elements. Production of viniplast products allows achieving significant savings and reduced volume of work involved; also, the material can be easily delivered by any vehicle.

Equipment:


Storage batteries of all kinds

Аккумуляторные батареи

 


Rechargeable batteries or batteries for short are divided into the following levels of performance:

 

  • Maintenance-free, are considered the most expensive, they do not have the possibility to fill in the electrolyte, and require a very stable electric power supply system;
  • Low maintenance require some level of density and control of the electrolyte. Are a bit outdated for today;
  • Served is the cheapest and require constant monitoring of electrolyte levels, which tends to boil away.

On the constructive device lead-acid storage batteries differ on batteries with liquid electrolyte of the WET or Flooded type.
On the constructive device lead-acid storage batteries differ on batteries with liquid electrolyte of the WET or Flooded type and the battery with adjustable VRLA or SLA valves. Last - the so-called sealed batteries, in turn, differ on the battery with wet-type separators, and AGM batteries with gel electrolyte type GEL. Depending on the material, which alloyed electrodes, lead-acid batteries are divided into antimony and calcium.
Sealed Battery - Lead-acid batteries that are regulated in the shell valves, which are used to reduce the in-situ pressure if tension increase occurs, for example in case of overcharge. Batteries of this type are also known as VRLA (Valve Regulated Lead Acid) or SLA (Sealed Lead Acid) batteries.
Sealed batteries have the following advantages:

  • The possibility of installation and operation in a horizontal position;
  • No acid leak, safe operation of other equipment is guaranteed;
  • gas emission into the environment is kept to a minimum;
  • No need to control the level and topping up the electrolyte.

Sealed batteries are used as power sources for portable equipment and tools in cases where the mass of the battery is not a critical factor, and at uninterruptible power supply systems for telecommunications systems, information systems for emergency equipment.


Аккумулляторные батареи ТНЖAlkaline batteries nickel-iron and nickel-cadmium traction type ТNZ and ТNК  are designed to supply power equipment on-board floor trackless machines electrified transport, especially electric loader.
Symbol structure HTNZ-H U2:

H - the number of series-connected batteries in the battery;
T - the drive;
NZ - a nickel-iron electrochemical system;
H - rated capacity, A•h;
U2 - climatic modification and category placement according to GOST 15150-69.

 

Heat-exchange equipment


ТеплообменникиHeat-exchange equipment, heat-exchange machinery - a device in which heat from hot fluid is transferred to cold or to that is being heated. Coolants can be gases, vapors and liquids. Depending on the purpose of heat exchangers are used as heaters and coolers. It is used in technological processes of oil refining, petrochemical, chemical, gas and other industries, energy and utilities.
Heat exchanger according to the method of heat transfer is divided into surface, where there is no direct contact of heat transfer fluids and heat transfer occurs through a solid wall, and mixing, where the fluids come into contact directly. Surface heat exchangers, in turn, are subdivided into recuperative and regenerative, depending on the simultaneous or alternate contact with the coolant wall separating them.
