Book excerpt: Excerpt from Dr. Edward Kirk's System of Foundry Practice: Cupola Practice The word "Cupola" covers such a variety of objects that another word should be used in conjunction with it to indicate the object referred to. such as cupola furnace or foundry cupola, but to men familiar with foundry practice the word cupola is sufficient. The cupola, in the melting of iron, has many advantages over any other melting furnace for foundry work. It melts iron with less fuel and more cheaply than any other furnace, and can be run intermittently without any great damage due to expansion and contraction in heating and cooling. Large or small quantities of iron may be melted in the same cupola, and the longer it is kept in blast the smaller the per cent, of fuel required in melting. These advantages have made it the melting furnace almost exclusively used in gray iron foundry practice. Theoretically, a ton of iron can be melted in a cupola with 172 pounds of coke, but in practice 250 pounds are required in long heats, and in short heats 300 pounds. This is due to the same amount of fuel being required for the bed for a short heat as for a long heat. The reverberatory furnace, a limited number of which are used in grey iron foundries in melting for special castings, requires from ten to twenty hundredweight of fuel to melt a ton of iron. The pot furnace, in which the metal is melted in crucibles, requires a ton of fuel to melt a ton of iron.

Book excerpt: Excerpt from The Philadelphia Correspondence Schools of Foundry Practice: Dr. Edward Kirk's System of Foundry Practice; Semi-Steel, Cupola Steel Castings, Malleable Steel Castings Semi-steel is a mixture of cast iron and steel scrap melted together in a cupola furnace, in contact with the melting fuel. A true semi-steel is composed of 50 per cent cast iron and 50 per cent. Steel, but these proportions are seldom used in mak ing mixtures, as it has been found that a smaller per cent. Of steel gives equally as good results and with more certainty of an even grade of semi-steel than the larger per cent. For castings desired to be soft and strong. But it is the common practice to call all cast iron containing steel a semi-steel. Steel is melted with cast iron for the purpose of increasing the strength of the iron, reducing the size of the crystalline structure of the iron and making a denser and closer metal that finishes and polishes similar to steel and gives a better wearing surface. Also to reduce the porousness of the iron and prevent leakage or sweating of the metal in fittings, valves, etc. Owing to the wide difference in the characteristics in foun dry pig, made from different ores, or smelted with different fuels, pig from the different furnaces frequently give different results when melted with steel and cast iron, even when showing the same analysis of the four elements commonly analyzed for in pig. For this reason no definite per cent, of steel that gives the best results can be stated that will apply to all iron.
