Grigoryev V.M., Zhatchenko Y.V. Possibilities of increase of operational properties of cast iron brake pads
Resource cast iron brake pads do not meet the requirements of operatives in connection with the non-uniformity of the microstructure of cast iron. This is confirmed by the results of the survey block that comes on the Far Eastern Railway. Modifying the iron ligatures zirconium improves life by 30% due to the alignment phase distribution and grinding grain.

Zhizhkina N.A. The refining of rolls cast iron out of furnace
The paper has been devoted to researches of refining of high alloyed cast iron out of furnace. It has been showed that hot metal is satiated by combinations of its components with oxygen, nitrogen, hydrogen and sulfur during casting of rolling tool. The refining of metal by introduction of special reagents and compulsory interfusion of the liquid metal with nitrogen in the ladle has been proposed. It has been established that such treatment reduces the sulfur content in the composition of complex alloy in 2 times and its contamination with non-metallic inclusions by 45% compared to unrefined metal.
Key words:Chrome-nickel cast iron, non-metallic inclusions, refining out of furnace, roll, sulfur chemical component, core, level of properties and stresses, roll.

The paper presents a method of producing bimetallic stamping for cast-solid forging alloys based on copper using a water- and gas-tight molds which are made from the moldable mixture, consisting of zircon concentrate, metallic shot, phenol-formaldehyde resins catalysts, backhouse dust. The backhouse dust is produced from waste gas streams in special centrifugal units are called backhouse electric arc steel and cast iron. Gastight shapes that are at the bottom of the form allow directional solidification casting of bimetallic upwards by applying a water-air coolant.
