SU823444A1 - Charge for producing complex silicon-manganese-calcium-aluminium-boron-titanium alloy - Google Patents

Description

. . -; I The invention relates to the production of ferroalloys, in particular in the development of mixtures of dl. obtaining complex alloys intended for reducing the doping and modification of cfaaefl and cast iron. The known charge for the production of calcium-aluminum-boron-titanium jfji combustible-manganese alloy containing wt.%: Quartzite Manganese carbonate concentrate I Known to Ferrobor slag Briquettes of titanium concentrate Koksik The disadvantage of the charge is low technological parameters of production purpose Purpose of the invention The technician of economic indicative of the process of the in-store of the silicon-manganese-calcium-aluminum-boron-titanium alloy shop and the use of non-deficient boron-containing raw materials. The goal is achieved. We note that as a boron-containing material, a datolite concentrate is used, which is briquetted together with the end of 1 titanium ohm, tkvarchel coal and quartz concentrate% 1M sand. Tkbupi coal is also additionally introduced into the charge, and manganese-containing material is introduced as a speck of medium-carbon ferrous ghana at the following ratio of compers, wt.%: 31-35 Briquettes Slag of average carbon 8-13 Dead manganese 1-3 Known to 20-25 Tkibul kulbroker 10-15 Koksik „.... Else Quartzite addition, briquettes contain, wt.%: Datolitic concentrate 13-30, Titanium concentrate 23-27 3S Tkvarchelsky coal concentrate 34-38 Quartz sandEartial Briquetting of datopite concentrate together with titanium concentrate and tricare coal concentrate allows you to increase the use of expensive titanium and boron. Quartz sand is added to improve the bonding of materials during the briquetting process. Example. In a furnace with a capacity of 1000 kV, experimental melting was carried out to obtain a silicon-manganese-calcium-boron-aluminum-titanium alloy at a known and proposed charge, the compositions of which are listed in Table. 1. Chemical compositions of the used charge materials are given in Table 2. Composition of briquettes, wt%: Datolite concentrate22 Titanium xycintate 25

Table 1 4 Tkvarchel coal concentrate 36 Quartz sand 17 Table. 3 shows the main performance of the furnace in the smelting of silicon-manganese-calcium-boron-aluminum titanium alloy. As can be seen from the table. 3, the use of the proposed mixture in comparison with the known allows to increase the use of silicon, manganese, calcium, aluminum, boron and titanium, respectively, by l, 4; l, 6; 5.2; 6.9; 7.8, and 5.8%, and the power consumption to reduce by 533 kW / / H - T alloy. The economic effect from the use of the proposed charge only due to a decrease in power consumption without taking into account the increase in the use of elements and a corresponding reduction in the cost of charge materials will amount to 8.53 rubles. per 1 ton of alloy.
