“…In this study, in which environmental effects of ADC were investigated, only the leaching of heavy metals within the body of WCS were examined. The assessment of the effects of pollutants such as VOC and PAH caused by various organic binder compounds and resins can also be considered as a different research topic [10].…”

“…Sucul ekosistem için toksik etkiler yaratan bu kirleticilerin etkilerinin en aza indirilmesi için ağır metal salınımlarının minimize edilmesi gerekmektedir. Bu kapsamda, her ne kadar bazı ADK'ları tehlikeli atık sınıfına girmese bile, uygun olmayan çevresel koşullar neticesinde sonraki tarihlerde ağır metal kirlilikleri oluşturabilirler [10]. Atık döküm kumunun özellikleri: Döküm sektöründen çıkan atık döküm kumunun özellikleri prosenin şekline ve içerisinde bulunduğu sanayi dalına bağlıdır.…”

“…The results confirmed their usefulness in modern reclamation processes. The authors explained the importance of reclamation and waste management in their paper on the approach to the problem of foundry waste [16]. They presented the vast experience of their foundry industry and focused on the reuse of solid waste, including the used sand matrix.…”

Influence of Weather Conditions and Mechanical Reclamation on Molding Sand with Alkali-Phenolic Binder for Manganese Cast Steel

The article presents the results of research on the properties of molding sands in Alphaset technology (alkaline-phenolic). These sands are often used in steel foundries, producing large castings. However, knowledge about them, and especially about the changeability of their properties with the change of environmental conditions (seasons), is still insufficient. Various compositions of molding sand were analyzed based on fresh chromite sand and reclaimed sand. A binder and hardener in various mass ratios were used to prepare the mass. The research methodology included, among others, tests of tensile and bending strength, permeability, abrasion, gas emissivity, and ignition losses. These tests were carried out for summer and winter conditions. The results showed the optimal proportions of resin and hardener, showed the influence of ambient temperature on the properties of the molding sand, and the possible ratio of reclaimed sand in relation to fresh sand. However, you should always remember to verify them under the conditions of a specific foundry.

This article presents the results of experiments related to the process of replacement of the currently used furfuryl resin molding sand technology with a new alkali-phenolic technology. The new binder is characterized by a set of technological advantages and is considered more ecological compared to the furfuryl resin. However, the molding sand produced on the basis of the alkali-phenolic resin features lower strength compared to the sands containing furfuryl resin. This article presents a comparative study of sands made using various alkali-phenolic binders, aimed at the selection of a resin with strength parameters and other features that are both desirable and useful for new technology applied in a foundry.
