Gas analysis equipment designed and manufactured by JSC "Soyuztsvetmetavtomatika" at current is presented. Equipment for highly specialized areas, including unparalleled are of particular interest. Much attention is paid to the indicators SAKS-1, GRANT-SHCH and GRANT-KS. All these indicators do not have analogues in the world. The indicator SAKS-1 is designed to control the leakage of sulfuric acid during transportation, storage and production. Similar in design and circuitry indicators GRANT-SHCH and GRANT-KS are oriented to determine the content of aerosols of sulfuric acid and alkali in the air when they are used as chemical reagent, such as for chemical milling. The operation principle of these indicators is based on the transfer of the aerosol sample from the air into a measuring cell and than measuring its concentration in a solution by ionometric technique. Devices send out alarms (sound, light, relay) on exceeding the maximum permissible concentrations or its multiple. Serial components and devices, mostly of domestic production, are used in the indicator. Using specially developed widget for gas samples conversion has its significant importance during installment, as known certain commercial sources of aerosols do not provide a quantitative standard samples. The design and circuitry of the flexible standard generator for hydrogen halides, combining advantages of current hydrogen chloride generator GRANT-HCl and containing aggressive resistance materials for hydrogen fluoride, is exploited. The use of such a generator allows by changing vessels with acid use in the laboratory one standard source for HF, HCl, HBr. © Designed by: "Ore and Metals" Publishing House.

This paper shows a brief analysis of the systems of heat treatment of rolled products and formation of their consumer properties due to the regulated formation of the crystalline structure of the finished products. Disadvantages of the traditional method of spray cooling are detaily described. At the same time, the control of cooling process is based on the use of mathematical models, which initial parameters for calculation and formation of the control actions are unsteady and probabilistic, which does not provide the rolled products quality at modern requirements. There is offered a fundamentally new method of regulation of the heat-removal rate by stirring cooling agent flow and design of self-organizing system. According to a new heat-removal method, the stirring flow of refrigerating medium is passed through the hollow plain rolls, set instead the traditionally applied one-piece sheaves, pressed to the hot water surface. The developed structure of control of heat removal from rolled product is described. Application of a new cooling principle shows the possibility of the problem solving of creation of production of thick unfailing rolled products in Russia with minimal costs. It also makes possible the operative increase of modern rolling mills productivity, improvement of consumer properties of ferrous or non-ferrous rolled metals, defect part reduction, energy-and resource-costs decreasing, sharp increase of ecological compatibility and significant increase of observability of the process parameters almost without the change of the main equipment design.

Quality of concentrating and metallurgical industries' feedstock is characterized by high volatility. This leads to unsteadiness of entire processing chain and affects the quality of the products. To reduce the unacceptable end product quality deviation is required continuously monitor the composition of the raw material, intermediate and end products in the production process and generate control actions to reduce the influence of disturbances caused by the variability of the composition of the raw material. The analytical control service work based on the principle of periodic sampling of different (predefined) process points followed by chemical analysis or hardware. New types of equipment for selection, training and sending of representative pulpar samples, as well as administration of these samples and their preparation for analysis in an automatic analytical control system are requested. Samplers to form pulpar increments taken from various production units, SAOP-04, the selection preparation and shipping of samples station, providing fulfillment of trainings conditions for pulpar samples in accordance with the regulations (State Standard, Branch Standart) are considered.

The problems of automatic optimal control systems of technological complexes of grinding non-ferrous and ferrous metals as objects with insufficient and noisy software are considered. A number of key variables (process parameters) are not directly measurable, can be estimated using indirect information that contains significant interference in this problem. This requires the creation of smart devices or even entire control system on the basis of the original special mathematical methods. For automatic process control grinding systems JSC "Soyuztsvetmetavtomatika" has created the devices such as granulometer PIK-074P, which allows to evaluate particle size distribution (PSD) of ground ore, vibroacoustic analyzers of mills loading VAZM-1 VAZM-1U, VAZM-1M, which allow the assessment of the technological burden mills , the current ore grindability and predict the time of a possible overload of mills. The appearance of these intelligent devices allowed developing automated systems of optimal control processes in all types of grinding mills, which has led to the creation of intelligent control devices such as VAZM-2U, which are incorporated in the original standard control algorithms. These devices can be sufficiently adapted to other process systems. The examples of structures of automatic control systems are given in the article. © Designed by: "Ore and Metals" Publishing House.

Information about modern techniques of flotation flow control, dosing device of flotation reagents on the basis of momentum energy-efficient batch pins and a new way of monitoring dosing activities is presented in the article. Dosing system is represented as a set of stand-alone dosing modules, allowing for projects of similar dosing systems of flotation reagents at concentrating plants for a wide range of performance. Complex pulp tester PP2 provides information about the density of the aerated and de-aerated slurry volume concentration of air in the pulp and the mass concentration of solids in the slurry, and the level of the pulp from the discharge threshold and on a conditional entry level of the pulp chamber of the flotation machine is of particular interest, since one such device provides a replacement for multiple devices. The article presents the formulas by which the computation of each of the six parameters being displayed on the front panel. Transfer of the aerated pulp in the deaerated state is carried out automatically by the control valve pacifier. Indications of pulp level measured by buoyancy level transmitter in the flotation machine chamber are adjusted by measuring the density of the aerated pulp. Objective control of the metering equipment using the measurement results of the current and the set flow rate of the reagent is proposed. The presence of a digital communication channel of microprocessor devices with the High Level Control System allows implementing closed-loop servo system using the information on the measured parameters. © Designed by: "Ore and Metals" Publishing House.
