JPS5890350A - Thermit composition for casting and method for forming molten metal for casting by using said composition - Google Patents

Abstract

PURPOSE:To increase melting capacity and to obtain desired molten metal for castings easily by melting a thermit compsn. for castings consisting of Al, iron oxide, scrap iron, etc. in a refractory reacting vessel, charging the same into an electric furnace and subjecting the molten metal to heat insulating and controlling of components. CONSTITUTION:Powder 5 of a thermit compsn. for castings consisting of 10- 20% Al, 32-70% iron oxide, 8-50% scrap ion, etc. is prepared. A suitable iron plate 10 is placed on the outflow nozzle 4 of a refractory reacting vessel 3, and the powder 5 is packed therein. The vessel 3 is installed on an electric furnace 6. Desired control element groups 7 are beforehand put in the bottom part of the furnace 6. The powder 5 is fired by a suitable means and is melted by thermit reaction by which slag 9 is separated in the upper layer part and molten metal 8 in the lower layer part. The plate 10 is melted by the heat of the metal 8 and drops together with the metal 8 into the furnace 6. Electricity is conducted to the furnace 6 to insulate the heat of the metal 8 or heat the same and to control the components thereof; thereafter the molten metal is tapped.

In addition, as the heating thermite method, there are special public HSO-/θ4J and Japanese public VJ-JooH.
The possibility of using the W& hot water produced by the thermite group destruction process as a one-purpose hot water has not yet been reported or put to practical use. Also, what about the addition of a combination of carbon, silicon, manganese, titanium, vanadium, chromium, and molybdenum? 1
Although it has been realized as the same as the above t1 of 1 contact O 砿 Kaede's sex, it is not Fi as it is added as pure cast stone.

The present invention provides a thermite composition for castings for borrowing *mw of desired castings, as well as the necessary proportions for the above-mentioned assembled products according to the purpose.
The above-mentioned chiller for foundry parts is made by mixing together or by adding necessary ingredients - tidy elements after the reaction of the main ingredients. 11) To produce casting bath water using %O'''C, the necessary ingredients are added experimentally, the losses are measured, and the mixture is mixed together in one package. Above all, it is convenient, but this 7j method'''c 5/part has a large loss of addition, and depending on the amount, it may be uneconomical.For example, when using bath soda for cutting cast iron. is a carbon molecule 2 in the -v component.
6~J, J≦, the sulfur content t7~4 is to be reduced or separated, but when mixed with the main carbon component, the average volume is about 40%, and the sulfur content is about 2j%. This is made with Cv, 2 portions are chilled, 1% IIC%, 1% Ayu O1! It is thought that this is because it reacts with the R-gas or -removal station volume and dissipates into the atmosphere, becomes 10g of gas, and is deposited in the slag. There are also vertical cables and other parts than silicon! It's been a long time since I watched the third series of beasts.
