“…It combines three successively carried out process: continuous casting, liquid stamping and hot forging [4][5][6]. When making metal products at the CHMCDI, it would be wrong to use the technological criteria of the individual processes that make up the combined process [7]. To obtain high-quality products with the desired properties (process stability), it is necessary to develop specific parameters of this new combined process, which are associated with the sophisticated mold design of the CHMCDI.…”

In order to obtain high-quality metal products with the desired properties (process stability) using the combined methods of metal casting and deformation, it is necessary to take into account the specific parameters of this process and the fact that the metal in the crystallizer stays simultaneously in several physical states: liquid, liquid-solid, solid-liquid and solid. Structurally, the mold consists of four walls moving relative each other along a given sophisticated trajectory. The object of the research is the production technology from non-ferrous alloys using the combined method of continuous casting and metal pressure treatment. The thermal processes occurring in the mold of a continuous horizontal metal casting and deformation installation (CHMCDI) during the formation of metal products have been examined as a research subject. The methods of physical modeling of the thermal processes which take place in the system “crystallizing metal-tool deformation” under different conditions of the mold cooling (using closed-perforated tubes and straight-flow tubes) have been used. Subsequent data processing of the full factorial experiment using the least square method as well as solving the optimization problem by using the Pareto principle of optimality made it possible to determine the optimal parameters for the process of obtaining metal products from aluminum alloys (TV = 40 oС; рv = 0.7 kg / cm2; SR = 5.8), which have been confirmed by the results of the experimental test on obtaining the strip from technical aluminum AD0 strip with a cross section of 40–12 mm.

“…In work [1], the results of a structural calculation of the cooling of the new structure for a continuous casting mold [2] is given in which in the steel walls vertical holes with diameter d n = 0.06 m are made, and the temperature drop of the cooling water in the steam condenser is Δt w = 10°. The drawback of the work performed consists in relatively low values d n , Δt w and the estimated low value of the heat transfer coeffi cient upon condensation of the coolant vapor.…”

The results of a structural calculation of the cooling of the wide and narrow walls of the industrial continuous casting mold with a specified value of the heat transfer coefficient with conden sation of the coolant vapor are given. A check of the use of copper and steel for production of the mold and condenser was made. A description of the full scale electrically heated mode of the mold wall is given to study heat transfer with given values of the heat flow density. The relation of the heat flow with the cooling parameters is defined. The novelty is proved by the patent on the method of cooling of the mold, mold model and the model of the device for metal cooling.
