Use of Quartz and Quartz-Feldspar Sands in Molding Mixes for Casting Iron

Use of Quartz and Quartz-Feldspar Sands in Molding Mixes for Casting Iron Use of quartz and quartz-feldspar sands for iron casting molds and rods is studied. A requirement is substantiated for their use as molding materials for preparing iron castings weighing up to 1500 kg and the casings of drying cylinders weighing up to 36 tons. It is concluded that it is preferable to use Gusarov, Karelian, and Finnish sands over other quartz sands. Portland cement, clay, water glass, graphite, and schungite, are used as well as sands. Carbon-containing materials are introduced into a mix composition in order to improve molding, physicomechanical, and anti-pickup properties. A mixture recipe, and metal melting and pouring technology are developed and proposed. In order to manufacture rods of sand-cement mixes in preparing castings of drying cylinder casings for papermaking machines it is necessary to use sand with a grain size of 0.5 – 1.0 mm with a clay component content of not more than 0.6%. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Refractories and Industrial Ceramics Springer Journals

Abstract

Use of quartz and quartz-feldspar sands for iron casting molds and rods is studied. A requirement is substantiated for their use as molding materials for preparing iron castings weighing up to 1500 kg and the casings of drying cylinders weighing up to 36 tons. It is concluded that it is preferable to use Gusarov, Karelian, and Finnish sands over other quartz sands. Portland cement, clay, water glass, graphite, and schungite, are used as well as sands. Carbon-containing materials are introduced into a mix composition in order to improve molding, physicomechanical, and anti-pickup properties. A mixture recipe, and metal melting and pouring technology are developed and proposed. In order to manufacture rods of sand-cement mixes in preparing castings of drying cylinder casings for papermaking machines it is necessary to use sand with a grain size of 0.5 – 1.0 mm with a clay component content of not more than 0.6%.
