Definitions
- the method of electrical processing of products from electrical products is known, including the use of electrical equipment with voltage of 220-230
- the task posed is solved by the fact that in the process of the production of electrical products from electrical products, which are included in the process, that is being processed
- 35 of the elec- trostrate discharge would use an aqueous concentrate of ammonia concentration of 2–6 wt.% At a temperature of 40–80 ° ⁇ .

- the effect of pouring water is increased, which consists in increasing the cost-effectiveness, reducing the operating speed of the process.
- the maximum cost-effective ability is achieved at the smallest thickness of the oxide layer, which is sufficient to eliminate the impact of electrical voltages.
- the pressure takes place in the first place in the world, where the resulting redundant layer is more toxic. Otherwise, due to the increased overload of the elec- tric charge in the charge, the product is a gas and gas appliance, which means that there is a risk of increased weight in the world.
- the operating ability and the roughness of the processed voltage depend on the value of the overloaded voltage, ignition
- the operating conditions of the samples were selected in the following range ⁇ : the operating voltage is 240-320 ⁇ , the temperature of the electric power is 40-80 ° ⁇ , the electric power is 2%.
- the best options for operating modes are made from the following units. e
- the operating area is occupied by the cigar zone, which is limited by the lines ⁇ , which does not take care of 5
- the decrease in the concentration of the electric power leads to an increase in the minimum values of the voltage ⁇ and the voltage of the electric circuit, which is somewhat more
- the temperature "L" and voltage ⁇ are close to the green one, that is, it is not suitable for the use of low power concentra tions.
- the proposed method is extremely accessible in the range of 20 voltage values from 300 to 320 ⁇ .
- P ⁇ i e ⁇ m value she ⁇ - ⁇ va ⁇ s ⁇ i ⁇ and ⁇ avn ⁇ bw 0.16-0.12 ( ⁇ ivaya I).
- Composite metal products were processed, in particular, procurements for the manufacture of dental appliances made from stainless steel.
- the bathroom parts are made from steel, which is $ 0.12 from $ 18 Cr, $ 9 W, ⁇ 1 $ ⁇ . , ⁇ s ⁇ aln ⁇ e - ⁇ e and ⁇ mezhu ⁇ ch- Nye li ⁇ aya Part - from s ⁇ ali, s ⁇ de ⁇ zhaschey C 0.2 $, 18 $ C g, 9 ⁇ , 2 $ 5 ⁇ , ⁇ s ⁇ aln ⁇ e - ⁇ e.
- Productivity lasted 2 minutes.
- Reliable treatment of compounded metal heals was selected in the following ranges: voltage applied to treated heals, 330-380 ⁇ , - 8 -
- the declared technology makes it possible to save the weight of a partly manufactured (bimetallic) product in a single technological mode, which increases the speed
- the use of an electrically operated product in the form of a potassium sulphate makes it possible to receive the product from the consumer electronics.
- the operating voltage in the unit is 330-380 and is based on that, which is
- this method of processing with optimal parameters was set at 70-90 ° ⁇ . If the temperature is lower than 70 ° C, the stability of the gas and gas spoils will deteriorate, the process will undergo significant 5 vibration and voltage fluctuations; at temperatures above 90 ° C, the quality of the products is reduced due to an increase in the chemical activity of electrolytes and disruption of heat loss - 10 -
- the use of the proposed method is based on the use of an electric hydraulically dynamic operating mode.
- the investigation of the high voltage of the electric field and the large temperature of the furnace has a chemically active 25 sr .
- the method is implemented by the following process.
- the seller with enamel insulation is loaded in a sink to a depth equal to the price of the end being cleaned. Lives a positive part of the load on the unloaded part, except 35-35 200. For this reason, at the lower end of the loaded part of the appliance, where after the absence of insulation, there is no need for a gas treatment. Due to the high temperature, which develops in the channels of electrical discharges, which reduce the voltage, the burning of the insulation on - - the return of the enemy.
- Example 5 We processed flat billets with a size of 30x20x1 mm, made from low-carbon steel, with a carbon cut of $ 0.08. P ⁇ d ⁇ lzhi ⁇ eln ⁇ s ⁇ ⁇ b ⁇ ab ⁇ i s ⁇ s ⁇ avlyala and 3 minu ⁇ y. The bad equipment ⁇ 33-35 $ (in the case of a silver mirror).
- the operating conditions of the samples were selected in the following ranges: operating voltage - 240-380 ⁇ , the temperature of the electrical unit - 8 ⁇ -95 ° C, the electrical power was 0.5–8 ° C.
- the selection of the local values of the operating conditions is based on the following considerations.
- Table 3 The pressures and settings for processing products from low-carbon steel (0-0,08 $) in the storage of ammonia
- Warehousing equipment for steam storage W 34 34 36 35 34 37 41 38 35
- the ⁇ increased value increased by a value of 0.25-0.23-0.
