On May 29-30, 2019 switch and rail commission session was held at JSC “DnSZ”. The switch commission summarized results of the works stated in protocol of 2018 and discussed questions for the next period: designing of turnout projects gauge 1435 mm and pieces with combined gauge 1520/1435 mm; designing of curved turnouts R 900 m and 1200 m; manufacturing of the turnout R65 type 1/11 gauge 1520 mm project 940 with increased wear resistance; designing of flat concrete sleepers for turnouts; life-circle prolongation of the turnouts’ parts by building up.   The rail commission discussed: increasing of maintenance period of the rails; effectiveness of lubricating devices; analysis of the maintenance of the testing models of rails and rail fastenings; plans for modernization of the production power of PJSC "AZOVSTAL IRON & STEEL WORKS”   The productive atmosphere made the session effective and interesting. All the details were discussed in a businesslike way; however, there were some significant remarks to the mentioned-above questions.  

In foundry № 1, hardening complex on the basis of the gas furnace «ТермоГаз НО 90.30.9 / 1150-НRс-И4» with an automated control system produced by “Kerammash” PJSC has been implemented. In order to expand export, improve the quality of products and eliminate the human factor on the hardening process of high-manganese steel, it was decided to install a hardening complex in foundry № 1. It allows making hardening of castings more than 9 m in length and responds all European technical standards (heating conditions, time reduction for heating-cooling transit of the casting, total absence of human factor). Thanks to the well-organized and hard teamwork of the staff of Chief Metallurgist Department and Foundry № 1, the work is carried out ahead of schedule (the deadline was April 30, 2019).

JSC "DnSZ" was honored to present its products at InnoTrans 2018. Moreover, it was a great pleasure to meet our long-term customers and get in contact with the new ones. The following products were displayed: solid manganese frog in accordance with EN15689 with four welded rail extensions and part of the end of switch point 60Е1А1 that made with canting of the pressed part 1:20.                    

Taking into account the need of the market for the production of mine turnouts and a custom-made manganese mining, the plant produced a turnout type P24 grade 1/2 gauge 600 mm Dn 944 which was previously manufactured by enterprises of Donetsk region. Switch transfer Type P24 ,mark ½  gauge 600mm on metal plates    The turnout is designed to provide rolling stock from one track to another in the underground, in pithead buildings, and on the surface of the mines where mine trains are operated. The turnout is placed on metal plates with subsequent welding of special terminals to these plates. Design features: - one-piece manganese steel cross-piece; - rail counter rail of P24 without exceeding from the tread surface; - pads in the transfer zone; - rotary wits from the rail P24; - base - metal plates; - manual transfer mechanism.   Main technical specifications Type Р24 Grade                                  1/2 Gauge on metal plates, mm                                     600 Total length of the turnout, mm                 3170±4 Radius of conversion curve, mm           4000 Counter rail                                            from rails P24 Maximum static load on the rail from the axis of the rolling stock, KH     70 Maximum speed, km / h   - on a straight path 9 - along the side path 6 Weight, kg, not more                                  548 Contents of delivery Frame rail straight with a sharp-witted curve and a counter rail of the type Р24 type 1/2 1 Frame rail curve with a sharp point and a counter rail type Р24 type 1/2 1 Crosspiece type P24 brand 1/2  1 Rail length mm:   - 796  1 - 891 1 Butt plates, pcs. 2 Plates, welding terminals, Compl. 1 Fasteners, set 1   Parts supplied by separate customer request Mechanism of manual translated 1 Butt Cover 10 Metal plates (base) 2 Bolt M20x105 (Dnp 6-02) or GOST 7805 24 24 Nut M20.5 GOST 15526 2 24 Washer 20 65G GOST 6402 24 Washer 20 GOST 11371 24     Allowed any configuration options according to customer needs, designed in the prescribed manner.
