“…It can be noticed, that the highest amount of dusts was formed as the result of the regeneration process of spent sand II, slightly smaller at the regeneration of spent sand I and the lowest at spent sand IV. It is assumed, that the amount of dusts generated during the reclamation process has an essential influence on the purification degree of the reclaimed material [4][5][6], since these dusts contain large amounts of the spent binder rubbed out from grain surfaces.…”

The results of investigations of the reclamation of spent moulding and core sands, originated from one of the Polish foundry plants, are presented in the paper. Four mixtures consisting of two types of spent sands (spent moulding sand and spent core sand) were subjected to the regeneration process. Each tested mixture consisted of an inorganic type spent moulding sand and of an organic type spent core sand. Proportions of mutual fractions of spent moulding and core sands in mixtures was 70%-30% and was representative for the waste sands from the foundry, from which these sands originated.

The purpose of this paper was to present an environmental assessment specific to a case study with reference to the storage of sand waste from a cast iron foundry, a factory with a long period of operation located in Transylvania, Romania. The environmental assessment started from the need to achieve compliant conditions for long-term storage of waste specific to cast iron casting parts activities. The activities performed in the project were carried out in stages and in parallel with the activities of sand waste valorification from the non-compliant deposit. The collaboration of the factory owner with the local environmental authorities was able to effectively materialize the objectives of the soil evaluation and facilitated the obtaining conditions for new compliant deposit construction. The evaluation of the soil quality was performed in areas where the deposited material, respectively the sand waste from the casting of the cast iron was already valorificated and, in that case, access to the soil layer was facilitated. Thirty soil samples and a control sample were analyzed and interpretation of the results was performed in corelation to specific legislation. The conclusions of the study were provided to the beneficiary and, also to the environmental authorities in order to authorize future activities (capitalization of the remaining waste, arrangement of a new landfill).

“…Among the others a pneumatic powder injection is a method of metallurgical quality of the produced alloys improvement and it has been well known since many years. It was examined and reported by many authors [8,9] including the article's authors, who specialize in the field of pneumatic conveying utilization in various industrial areas [10,11,12,13]. In many cases the injection lance can be submerged inside the molten metal e.g.…”

The paper presents the results of model experiments with new lance design. The lance was invented in Silesian University of Technology, Department of Foundry. It is dedicated for the pneumatic powder injection into liquid metal bath without lance submersion. The situation like that is common for small molten alloy volume when the problem of temperature decrease is significant. In such case the carrier gas introduction into metal as well as cooling with gas blowing onto metal bath surface should be avoided. The new lance was equipped with four parallel slots made on its outlet and a flange. This design causes the carrier gas evacuation before it reaches the molten metal surface. The article presents the model experiments made with use of the device for the diphase gas-powder jet forces recording. The comparison of two lances: normal steel pipe and this of new design was presented in the article, too.
