Abstract In-situ TiB2 particles can be synthesized via the salts-Al reaction by adding mixed K2TiF6 and KBF4 (Ti/B=1/2) salts into Al melt. In this research, a novel electroslag melting technology was proposed to synthesize TiB2 particles by the salts-Al reaction in order to reduce the reaction time period and purify the melt of composite. The effects of current of electroslag melting on the synthesis of TiB2 particles and mechanical properties of composite were investigated. The results showed that TiB2 particles could be in-situ synthesized by electroslag melting at 600 A for 15min. Compared

The issues related to the continuous compensation of metal shrinkage during its crystallization are studied. Based on the evaluation of ways to reduce the size of the shrinkage shell, aimed at maintaining the liquid phase for a long time, the most effective ways to reduce the size of the shrinkage shell and reduce the head trim are selected. The influence of electroslag heating and recharge technology on the length of the shrinkage shell and the quality of the metal of the sub-shrinkage area of semi-continuously cast ingots has been studied.

One of the effective methods of surfacing protective coatings on large areas, as well as the formation of permanent joints is the method of immersion (dipping) of parts into the melt. In order to increase the productivity of this method, the quality of surfacing is proposed to heat the work surfaces of the parts with an electroslag method. The rational regimes for its realization are determined by calculation. A mathematical model is proposed for heating the contacting layers of a solid body, slag and melt, taking into account the Joule heat released during the passage of an electric current.

This article discusses the issue of increasing the efficiency of alloying low-carbon steel during electroslag remelting with fluxes obtained on the basis of multicomponent mineral raw materials. The process of transition of an alloying element, from molten slag to metal, was investigated in various operating modes of the slag system, where the system itself experienced various degrees of hydrodynamic impact. A model is proposed and described, showing the uneven distribution of the alloying element in the metal melt. The composition and structure of the obtained alloys are investigated.

Alloys used for the production of rotating components in aeroengines and land-based turbines are subject to stringent requirements to ensure absence of melt-related defects such as inclusions and segregation. Accordingly, the production of the superalloys alloys used in these applications involves multiple remelting stages, each of which plays a distinct role in ensuring that the final ingot is defect-free.

The electroslag refining (ESR) process is used to produce high‐quality alloys for critical applications. Chemical reactions between steel and slag during ESR have been studied experimentally and with the help of kinetic models. However, there is limited work on alloying during the ESR process. This work reports chromium alloying of mild steel during the ESR process. Chromium alloying in mild steel, up to 2.1 wt%, is achieved by adding Cr2O3 to the slag using different means under laboratory conditions. The mechanism of Cr2O3 reduction and loss of aluminum during ESR are studied with the help o

The composition of electroslag has a great influence on the remelting behaviour, and the electrical conductivity and viscosity of slag directly affect the energy consumption and the surface quality of the alloy. The electrical conductivity and viscosity of CaF2–CaO–Al2O3–SiO2–MgO–TiO2 slag system with different CaO/Al2O3 (0.9–1.8) were measured by a high-temperature physical property measuring instrument, and the structure of the slag was analysed by FTIR and Raman spectroscopy. The results showed that the electrical conductivity increased from 0.027 to 0.071 S · cm−1 and viscosity decreased f

Molecular dynamics simulations were conducted to elucidate the effects of MgO/Al 2 O 3 and MgO/CaF 2 ratio variations on the structure and viscosity of CaF 2 −Al 2 O 3 −MgO melts. Results indicate that in basic environments, Al 3+ acts as a network former, strongly bonding with O 2− ions and predominantly existing in aluminum−oxygen tetrahedral configurations. Increasing the MgO/Al 2 O 3 ratio promotes the substitution of F − by O 2− in [AlO 3 F] 4− units, fostering the formation of non-bridging oxygen structures. This leads to a decrease in highly polymerised Q 4 and Q 5 units, causing networ
