100%
PL
W pracy przedstawiono wykorzystanie programu ARENA do symulacji procesu produkcyjnego, przykładowo wytapiania i odlewania staliwa, monitorowanego autorskim programem komputerowym pod względem zgodności z wymaganiami technologicznymi. Na podstawie danych z symulacji określono wartość odpowiednich składników kosztów jakości i kosztów międzywydziałowych związanych z usuwaniem niezgodności z technologią przygotowanego staliwa.
EN
It present use of ARENA for simulation of production system for example of melting and casting of cast steel, in respect of acceptability status monitored technological method of thermal and derivative analysis with author software. Value of component of costs of proper quality define of base from simulation data and with deletion of incompatibility with technology prepared interdepartment costs of cast steel.

It plaster moulds gets casted the alloys of following metals: Al, Cu, Ag, Au in precise and artistic founding. The investigation of the crystallization of bronzes in hot plaster moulds the method of the thermal analysis and derivative (TDA) was not realized out so far. Probe TDAg and tripod enabling the execution of measurements on inductive casting machine INDUTHERM-VC 500D were designed for this technology especially. It was confirmed that one the method TDA can identify the crystallization process of the bronze in hot plaster moulds. The investigations of the superficial distribution of the concentration of elements in the microstructure of the studied grades of the bronze on X-ray microanalizer were conducted. It results that they be subject to in bronze CuSn10-C (B10) and the CuSn5Zn5Pb5-C (B555) of strong microsegregation from conducted investigations: Pb, Sn and Sb. The single separates of intermetallic phase \kappa was identified in the bronze B10 rich first of all in Zn, Sn, Sb and Fe, and two intermetallic phase, one rich were identified in the bronze B555 first of all in Zn, Sb, (Nor, Fe) and second rich in Sn, Sb, (Nor, Fe). The most homogeneous microstructure from the bronze CuAl10Fe5Ni5-C (BA1055) is characterizes among the studied grades of the bronze in the cast state.

The paper presents the influence of the type of furnace charging melting, refining and modification silumins 226 and 231 on the porosity and microstructure of castings. It was shown that in order to reduce or eliminate the porosity of the castings is necessary to the refining ECOSAL-AL113 of liquid silumin both in the melting furnace, and in the ladle and an additional nitrogen, in the heat furnace modified and refining with nitrogen. To control the effects of refining and modifying the TDA method was used. It was found that based on crystallization curve can be qualitatively assess the gas porosity of the castings. In order to control and quality control silumins author developed a computer program using the method of TDA, which sets out: Rm, A5, HB and casting porosity P and the concentration of hydrogen in them. The program also informs the technological procedures to be performed for liquid silumin improper preparation.

W pracy przedstawiono autorski System Komputerowy Kontroli i Sterowania Jakością Siluminów (j. ang. CAQCSS - Computer Aided Quality Control of Silumins System) przeznaczonych na koła samochodowe - felgi. W programie sterującym systemu wykorzystano metodę ATD. W pracy podano charakterystyczne wielkości wyznaczane tą metodą, stanowiące podstawę opracowanych zależności statystycznych oraz przedstawiono istotę komunikacji systemu z operatorem w zależności od zawartości wodoru w ciekłym siluminie. System wdrożono w Federal-Mogul Gorzyce S. A.

It presents Computer Aided Quality Control of Silumins System with use of TDA method. It serves characteristic largeness, appoint TDA method, which are elements of elaborated mathematic equations and it presents idea of communication of system with operator depending on H2 content in liquid silumin. The system has implemented in Federal-Mogul Gorzyce S. A.

The work presents the results of the investigations of the effect of intensive cooling of alloy AM60 with additions of chromium and vanadium on the microstructure and mechanical properties of the obtained casts. The experimental casts were made in ceramic moulds preliminarily heated to 180°C, into which alloy AM60 with the additions was poured. Within the implementation of the research, a comparison was made of the microstructure and mechanical properties of the casts obtained in ceramic moulds cooled at ambient temperature and the ones intensively cooled in a cooling liquid. The kinetics and dynamics the thermal effects recorded by the TDA method were compared. Metallographic tests were performed with the use of an optical microscope and the strength properties of the obtained casts were examined: UTS(Rm), elongation (A%), and HB hardness.

The work presents results of the investigations of effect of intensive cooling of alloy AC-AlSi7Mg with alloy additions on microstructure and mechanical properties of the obtained casts. The experimental casts were made in ceramic molds preliminarily heated to 180°C, into which AC-AlSi7Mg with alloy additions was poured. Within implementation of the research, a comparison was made of the microstructure and mechanical properties of the casts obtained in ceramic molds cooled at ambient temperature and the ones intensively cooled in a cooling liquid. Kinetics and dynamics thermal effects recorded by the TDA method were compared.
