Casting Pouring Procedure
During pouring process of casting production, which should be followed the principle that when pouring temperature, low temperature pouring. Because when improved the temperature of the liquid metal, helpful to the complete fusion, slag inclusion floating, it convenience of slag removal and degassing, and porosity defects to reduce the slag inclusion and Blowhole defects of the products. Use lower pouring temperature, it can be reduce the gas solubility of the metal liquid, Liquid shrinkage and high temperature of metal liquid to bake on the surface of the cavity, to avoid producing defects such as hole, burnt-on sand contraction cavity. so, In guarantee under the premise of full of mold cavity, try to adopt low pouring temperature. The processing pouring metal liquid to the casting mould is referred to as casting. Pouring improper operation may cause the misrun and cold shut, machine casting defects such as porosity, shrinkage cavity and slag, and cause personal injury.
