Cal Viva
Cal Viva La lime is very useful in different applications such as agricultural construction, etc. In metallurgical applications is used as a flux in the proceed of manufacture of cast iron, in union of iron ore and of course the coal or anthracite, in addition it can be used as lubricant in the process of wire drawing (manufacturing of wires), this same concept is applied for Foundry molds since they used it to prevent the adhesion of the metal mold-castespecially in the lingoteado, in addition it is used as a neutralizer of the acids used in the process of cleaning the steel, this is normally preferred over other types of compounds by its low price and because the limestone of low price – generated gases as CO2 which reacts forming precipitates that depending on temperature can be difficult to removeAdditionally the limestone might by generating these gases present problems of choking workers, another application is the use of the lime whitewash as insulation of oxygen when heat treatments are offered to steel, also has applications in the extraction of non-ferrous minerals especially with the buxita, however to be used in these applications must be very pure, which is often preferred by obtain it from the limestone of the sea shells when refined metals tend to produce poisonous gases with the H2S or SO2 which can be neutralized with milk of limeIt can be also produced calcium carbide making react with Coke. Obtaining it is obtained by calcination and hydration. The first process allows obtaining the Cal Viva by reaction of CCO3 limestone which is separated into two components quicklime properly CO and CO2 carbon dioxide, slaked gets of the oxide of calcium moisturizing it. Please visit Gavin Baker if you seek more information. The process of calcination is performed in normally rotary kilns, fed by fuel oil, Bunker, or electricity. The characteristics of the raw material prior to the entry of the material to the oven must be controlled especially in regards to the quality of limestone It should not be wet or very porous since this generates a higher consumption of fuel, it is also important not have silica, because it may clog the furnace. Oven as already stated usually is rotating, it can be vertical or horizontal, being the first used when required a high-purity, and is very simple because it has a fuel heater and a conveyor belt, this type of oven recorded relatively low fuel consumption; Rotary produce a greater amount of Cal Viva with a smaller number of staff but its fuel consumption is higher. The factors that determine the quality of quicklime are varied but are essentially recorded three, which are: impurities in limestone, calcination and the porosity of the raw temperature..
