“…A no less important factor in implementing continuous casting is the casting rate since productivity depends directly upon it. The effect of casting rate on the properties of the bars obtained depends strongly on the cast alloy composition [10,13]. An increase in casting rate leads to an increase in heat removal in a side direction that leads to a change in grain growth direction [10,14].…”

Billets made of bronze Br010S2N3 are usually produced using a permanent mold casting technique with a low product yield. Properties of the bars 25 mm in diameter obtained using an upcasting method with different casting rates (from 120 to 280 mm/min) are investigated in the present work. It is shown that with increase in casting rate the amount of γ -Cu 3 Sn intermetallic phase in the bronze microstructure increases slightly that leads to an increase in wear resistance. Tensile mechanical properties, hardness, and thermal conductivity of Br010S2N3 bronze are independent of casting rate. However, a fast casting rate (280 mm/min) leads to an increase in shrinkage porosity, so a casting rate of 220-250 mm/min is recommended in order to produce high-quality Br010S2N3 bronze rods.

Thise research was conducted to determine the impact of the applied casting technology, mould and alloying additives on the tightness of the CuSn10 cast alloy. Under industrial conditions, a series of experimental melts were made that were characterised by varying the concentrations of the main alloying element (Sn) and the introduced alloying additives (Si, Zn, Zr). The mould was made from green sand and used the CO2 moulding process. To assess the influence of the alloying additives, a metallographic analysis of the studied alloy was carried out, and the alloy’s microstructure was examined using optical and scanning electron microscopy. The introduced alloying additives affected the properties and microstructure of the studied alloy. As alloying additives, zirconium resulted in a visible refinement of the microstructure, while silicon improved the fluidity and quality of the casting’s external surface. The use of alloying additives and moulds made using different technologies is intended to improve the structure of the tin bronze castings produced and to find the best solution to significantly eliminate the lack of leakage of the castings. The castings were subjected to mechanical processing, and a leak test was performed using the pressure drop method. The conducted research allowed us to determine which technology, applied to production, will bring about a reduction in the problem and will inform further investigations.

“…For the vertical continuous casting process, there are casting machines which can cast products vertically up or down. Unlike vertical downward continuous casting, the continuous vertical downward casting process uses gravity to feed the metal into the mold [4]. This process which is used in this study is widely used in industry and especially for the manufacture of steel bars and other metal alloys.…”

The purpose of this study is to present the production of lead rod by the use of vertical downward continuous casting. The lead rod was characterized by optical microscope, by scanning electron microscope equipped with EDS, by X-ray diffraction and by Vickers microhardness measurements. The results obtained showed that the lead metal produced by this process has properties similar to the rod used for its production.
