foundry coke is widely used for ironmaking and foundry,we expot it with high quality and good price
DEFINITION
Metallurgical coke is the blast furnace coke, foundry coke, ferro-alloys and nonferrous metal smelting with coke coke collectively. Since more than 90% of metallurgical coke for blast furnace are therefore often referred to as blast furnace coke metallurgical coke.
Foundry coke is dedicated cupola melting iron with coke. Foundry cupola melting iron is the main fuel. Its role is to make hot metal melting furnace charge overheating, column material support to maintain its good permeability. Therefore, the Foundry should have a block of large, low reactivity, porosity is small, with sufficient impact crushing strength, and low ash and sulfur content.
APPLICATION
Blast furnace and coke used for copper, lead, zinc, titanium, antimony, mercury and other nonferrous metals smelting blast furnace, from the reducing agent, heating agent and the material column skeleton. Blast furnace using coke instead of charcoal, a large modern blast furnace laid the foundation, is a major milestone in the history of metallurgy. For blast furnace operation to achieve better technical and economic indicators, smelting with coke (metallurgical coke) must have the appropriate chemical and physical properties, including the smelting process of thermal nature. In addition to a large number of coke for iron and nonferrous metal smelting (metallurgical coke), but also for casting, chemical, calcium carbide and ferro-alloys, their quality requirements are different. Such as foundry coke, generally require large size, low porosity, high fixed carbon and low sulfur; chemical gasification of coke, strict requirements for strength, but requires a good reactivity, ash melting point higher; calcium carbide, coke production required to maximize the fixed carbon content
