Horizontal continuous casting of iron and alloy iron has expanded into many more geometric forms than simple round bar. About 100 continuous casting strands are now on line, producing about 30,000 tons yearly in Europe and another 6000 tons yearly in North America. These forms include square bar, channels, hollow bars, tube, even profiles for milling machine tables. Operating experience of the authors shows that continuous casting of these shapes competes economically with centrifugal, sand and static chill casting of equal quality. They show how their own continuous casting plant prepares for continuous casting, present metallurgical aspects of the process and show the influence of rapid cooling in the graphite dies employed affects graphite form and microstructure. Several extensive examples illustrate operating costs for a continuous casting plant with the object of amortizing these costs over 5 years on a one-shift basis. The operating costs for a continuous casting plant break down to 4.7 cents per lb not including cost of the metal melted and poured. This is for a one-strand machine. When a 4-strand machine produces 750 lb/hr of 2-in. dia. bar, operating costs drop to 2.6 cents per lb.鑄件展-鑄件采購(gòu)會(huì)-國(guó)際鑄件展-2017第十八屆廣州國(guó)際鑄件展會(huì)-巨浪展覽-The 18th China(Guangzhou )Int’l Casting product Exhibition
