Melnikov A.P. Technologies and Equipment for Casting Cylinder Liners for Internal Combustion Engines
Developed comprehensive technologies and units for making cylinder liners by centrifugal casting and lined metal mold casting are reported.
Key words: casting, centrifugal casting, metal mold casting, casting defects, structure.

Koltygin A.V., Tsynovnikova Y.P., Plisetskaya I.V. Defects in Magnesium Castings Made in Sand Molds Produced by the 3D Printing Method
The article discusses issues related to the peculiarities of making magnesium alloy castings in molds produced by the 3D printing method without using pattern tooling. Some experiences of casting in molds made by printing on ProMetal S-15 3D printers are summarized. Peculiarities of formation of gas shrinkage porosity in molds of that type are discussed. A new kind of casting defect occurring in that casting method is described for the first time. Using casting process computer simulation programs ProCast and POLYGON, riser sizes for alloys of the ML5 type have been defined more precisely. The role of external chills in the formation of a sound casting has been considered.
Key words: magnesium alloys, casting, porosity, molding, 3d-printer, sandcasting cores, molds direct from CAD data, Z-cast.

Kuzembayev S.B., Berezyuk V.G., Sinichkin A.M. Gas-Dynamic Aspects of Compacting Molds and Cores with Compressed Air
The work presents a classification and analysis of mold compaction methods using airflow. It is shown that the main factors influencing the process parameters are gasdynamic ones.
Key words: compaction, molding sand, gas-dynamic parameters, sand density, pressure buildup rate.

Blinnikov A.Y. About New Methods of Technological and Organizational Management in the Foundry Industry
Application of intelligent data processing procedures based on neural network algorithms is proposed to solve the problems of technological and organizational management in the foundry industry. Examples of using neural network technologies that show the availability of that trend are given.
Key words: neural network, synaptic matrix, casting defects, associative memory, weight coefficient.

Abdullin A.D. Technology Optimization in Automatic Mode in the SOLIDCast Software Package
The article discusses an example of optimizing the technology of making a "Wheel" casting using an additional module OPTICast (SOLIDCast software package).
Key words: delkam-Ural, SOLIDCast, OPTICast, casting technology analysis, technology optimization, shrinkage defects analysis, risers, casting yield, castings.

Enzenbach T. Long Campaign of Cupolas with a Capacity of up to 10 t/h
Measures to extend cupola campaign allowing to increase its capacity and improve melting conditions are reported. There were examined a liningless cupola having a number of advantages, and a lined cupola that had the advantages of the former, but would have no disadvantages of it.
Key words: cupola, campaign, refractory lining, tuyere cooling circuit, slag channel, hermetic siphon

Potanin S.L., Golkina V.A., Trofimov Y.F. Cast Products Quality Management
Results of expert evaluation reflecting foundry specialists' opinion about the degree of influence of groups of various causal factors on the occurrence of inconsistencies of piston castings with Ni-resist insert are given. The obtained data have been used in introducing methods of product quality management on the basis of forming personnel competences at OAO Avtodiesel Foundry.
Key words: casting defects, personnel competences, expert evaluation.

Turilova K. On The Right Path to Quality. Modern Methods of Foundry Castings' Quality Control
Quality improvement of production is one of the factors to increase profitability and to build working relationship with foundry customers. According to the IFC study "Resource Efficiency of Foundry Industry in Russia" quality requirements in Russia are less strict than in EU. While average reject rate of EU ferrous foundries is 3.4%, Russian foundries judged against similar EU standards will have 14.3% of reject rate at average. Such high rates could lead not only to loose of customers but also increase costs on resources as a foundry will need to production the same amount good-quality castings. The author presents a review of modern castings quality check methods that could decrease reject rate at Russian foundries.

Boldin A.N., Mikhailov D.P. Ecological Evaluation of Harmful Emissions from Arc Melting of Steel at the Design Stage
A procedure of calculating possible harmful emissions in the form of gas and dust, and loss of alloying elements, at the design stage is presented, which will allow working out cleaning measures in advance.
Key words: environmental safety, emissions, furnace charge material, alloying elements, slag.
