Combined feed (fodder) is a homogeneous mixture of forage resources (grain, bran, fodder of animal origin, mineral supplements) high in protein, vitamins and minerals for farm animals and poultry nutrition. Depending on fodder feeding value it is divided into: full fodder, mixed fodder concentrates, balancing fodder supplement (protein-vitamin, protein-vitamin-mineral) and premixes.
Extrusion method is the most popular among all methods of animal feed production. It allows to improve the qualitative properties of the end product compared to traditional methods. During the production process the feed is effected by brief and very intense mechanical and barothermal impacts, which are followed by structural, mechanical and chemical feedstock changes. Due to the short duration of the process, vitamins and amino acids, which are contained in grains, are almost completely saved. And digestibility is increased to 90%. Extruded feedstock is practically not affected by bacteria when stored under normal warehouse conditions (for 3-4 months). This fact is of special value for the fattening of young animals (cattle, pigs, horses, rabbits, etc.). Feeding young animals with extruded feedstock 1,5-2 times reduces their gastrointestinal disease mortality. It should be noted that the quality of the finished product is not affected by humidity of the processed raw materials and possible small number of seeds of other crops.
Flowsheet and equipment are selected depending on formulation and the manufactured feed, find out more:

During cold rolling, stamping or drawing the grains of the metal deform and crush. This effect is called hardening. The hardening increases metal hardness and reduces its ductility, causes brittleness. Recrystallization annealing is used to eliminate hardening. In the shops of cold rolling, recrystallization annealing is used as:
The temperature and amount of flow of air is determined by the physico-chemical processes of melting, which in its turn greatly influences the change of furnace productivity and fuel consumption. The exposure the hot blast to the blast furnace process is especially effective when enriching it with oxygen supplied to the intake manifold blowing machine. In addition, directly to the tuyeres of the furnace can be supplied extra fuel - natural gas, coal dust, oil. more info
After hot drawing and pickling of rolls steel surface has many asperities, leave alone the fact that during the pickling in continuous units rolls are welded together and seams are formed. Whereas, when a defect or suture enters the mill stand, it is necessary to reduce the speed of the strip to prevent deformation of the rollers and provide better rolling. One roll can be rolled in a reversing mill to 3-7 times (passages). During the first pass, the speed reduction is carried out by the operator (notes defects). The automated system detects defects and on the next pass will automatically reduce speed during their passage through the cage. more info
The roll-forming machine works on the process of shaping by piece. The material is rolled steel. The range of sizes of the mill includes bent channels of various configurations: equal channels, furring channels, C-channels, special channels, goffered sheet channels. The leveling machine is located in the line of the roll-forming machine behind the decoiler for rolls and is intended for ultimate straightening band coming from the unwinder. After a leveler the band is delivered to scissors with the lower cut for trimming the front end of the hot rolled strip, and cutting strips on dimensional (> 6 m) length.
As a result of implementing the system employees received convenient and multifunctional tool for the process control, automatic cutting the strip, as well as the ability to control and analyze the archive of technological process parameters. more info

During the continuous strip moving at a constant speed through the technological line arises the need of stopping head or tail part of the machine for welding the ends of rolls, the weld cutting, installing the roll on the uncoiler and removal of the roll from the winder after handling on the line.
Currently, at the head and tail parts of the machine are installed devices providing a stock the strip for the welding process, as well as installation and removal of the roll. Such devices are loop pits with freely sagging loop. more info
Railway wheels are in the list of the most critical elements of the rolling stock of the rail transport. While train movement the wheels are affected by static, cyclic and dynamic load, and in local areas (while slowing down) – by cyclic influences of high temperature. Every wheel element has a rapid time-varying system of compressive and tensile stresses. The voltage wheel–rail contact lead to breakages, most of which can be classified as rolling surface wair, thermal and contact–fatigue defects, brittle metal fracture.
The most important railway wheels quality parameter is hardness. Hardness requirements for wheels are established by national and international standards.
Automated control system of railway wheel rim hardness measurement node was created to fulfill the railroad wheels quality requirements, and is based on EMKO hardness tester see more information:

To form a ceramic shell the refractory coating is subjected to air, air-ammonia and ammonium-vacuum drying. The practice shows, the drying duration depends on the number of applied layers and model complexity and differs significantly for different methods. Thus, it is possible to dry coating on air for 4-10 hours, air-ammonia drying lasts for 1-3.5 hours. The most rapid way is the ammonium-vacuum drying which takes from 15 to 30 minutes.
At the end of the process the model composition is removed from shells by melting of different methods (in hot water; in the molten model composition of the same brand, with hot air) at temperatures of 96-200оС.
To monitor the progress of the drying process and management of the unit the ACS is created... more info
Nowadays oxygen has wide application in metallurgy, chemical, petrochemical, pulp and paper, food industries, power engineering, medicine and agriculture. It is obtained from air by cryogenic distillation and water electrolysis.
Oxygen is transported in cylinders. To fill them up gas is supplied through the pipeline to the filling manifold—ramp, to which the cylinders are attached. Filling manifold consists of two identical branches, branch connection node and racks. There are valves for connecting the cylinders on each branch and one end valve for pulling the gas from the branch. The connection node of the branches consists of two valves (gas flow into the branches), pressure gauge and safety valve.
Filling ramps are of two types:

In a case of batch production, large-scale and mass production of castings to improve the quality and increase the productivity of labor machine methods of making molds are used. At the same time, along with molding machines in cast shops sand-throwing machines are used.
The sand-throwing machine is throwing molding machine, which throws a moldable mixture in the flask at the same time filling it and making compaction of the mixture. Usually, sand-throwing machine are used to stuff medium and large forms, since the size is too small flask obtained significant loss of molding sand, and since the size of the flask is too small there it can result significant loss of molding sand, because of missed sand while stuffing near the edge of the flask. The following types of sand-throwing machines are:
