RECYCLING OF WASTES FROM CAST IRON CASTINGS PRODUCTION
Abstract
Production of castings plays an important part in the global and in the national economy. The main recipient of the foundry production is the automotive industry, but castings find application also in other branches of industry, in civil engineering, in farming, in medicine, and can as well serve art production. In 2016, worldwide casting production reached 104.1 million metric tons, a shade over the 103.7 million metric tons produced in 2015. The remaining 2015 top 10 casting nations by tonnage are Japan at 5.4 million, Germany at 5.3 million, Rusia at 4.2 million, Republic of Korea at 2,6 million, Mexico at 2.56 million, Brazil at 2.32 million and Italy at 2.03 million (Slovakia 96 000 tons). Of the countries that reported growth, India?s and Mexico?s were the most significant in terms of tonnage, but several smaller nations reported double digit percentage increase, including Bosnia and Herzegovina, Portugal, Romania, South Africa, and Sweden. Solid waste makes up a large portion of the pollution from foundries. The most wastes come from sand, slag, dust and spent refractories. Sands waste from foundries using sand moulds has been identified as the most pressing waste problem in foundries. Moulding and core sand make up 66 ? 90% of the total waste from ferrous foundries. Actually the main fraction (about 60%) of the wastes coming from the foundry plant is landfilled, a minor part (about the 10 ? 15%) is recycled in concrete production. The other wastes, made of moulding sand and broken cores, are partially reused for core making after some regeneration treatments performed in internal and external plants. In Slovakia used moulding and core sand are partially recycled in foundry (regenerated) but dusts and slag are landfilled. The contribution shows the possibilities of recycling, utilizing or next treatment three the most widespread foundry wastes: used sand, dust from foundry processes and slag from melting processes in foundry.
