Description
В термообработке примен ют двойные сплавы едкого натри с хлористыми сол ми, например 80% едкого иатри с 20% хлористого бари , при температуре плавлени сплава 282°.Heat treatment uses double alloys of sodium hydroxide with chloride salts, for example, 80% sodium hydroxide with 20% barium chloride, at a melting point of the alloy of 282 °.
Известен также четвертной сплав солей следующего состава: хлористый натрий-3,2%, хлористый барий-3,2%, хлористый калий-3,2%, едкий натрий-87,1%. Температура плавленн этого сплава-268°.Also known is the fourth alloy of salts of the following composition: sodium chloride-3.2%, barium chloride-3.2%, potassium chloride-3.2%, caustic sodium-87.1%. The melted temperature of this alloy is 268 °.
В р де случаев дл закалки, отпуска и изотермической обработки стальных изделий примен ют низкотемпературный сплав следующего состава: азотнокислый натрий-55%, азотнокислый калий-45%. Температура плавлени этого сплава-221.In a number of cases, a low-temperature alloy of the following composition is used for quenching, tempering and isothermal treatment of steel products: sodium nitrate-55%, potassium nitrate-45%. The melting point of this alloy is 221.
Предлагаетс бинарный сплав солей следующего состава: едкий натрий-62,5%, углекалиева соль-37,5%.Температура плавлени этого сплава-238°.A binary alloy of salts of the following composition is proposed: caustic sodium — 62.5%, carbonate salt — 37.5%. The melting temperature of this alloy is 238 °.
Преимущество предполагаемого сплава по сравнению с известными сплавами заключаетс в том, что он имеет более низкую температуру плавлени и способствует уменьшению разъедани поверхности стальных изделий и их осветлению.The advantage of the proposed alloy compared to the known alloys is that it has a lower melting point and helps to reduce corroding of the surface of steel products and their clarification.
Предмет изобретени Subject invention
Низкотемпературный бинарный сплав дл термической и изотермической обработки с температзрой плавлени 238°, отличающийс тем, что, с целью умепьщенн разъедани поверхности стальных изделий н их осветлени , примен ют смесь солей едкого натри в количестве 62,5%, углекалиевой соли-37,5%.Low-temperature binary alloy for thermal and isothermal treatment with a melting temperature of 238 °, characterized in that, in order to reduce the erosion of the surface of steel products and their clarification, a mixture of caustic sodium in the amount of 62.5% is used, the carbonate salt is 37.5% .
