Description
Изобретение относитс к черной металлургии , в частности к составу хромоникелевой аустенитной стали с карбидным упрочнением, обладающей повышенной жаростойкостью при температуре 1000-1200°С, дл изготовлени деталей, работающих в услови х периодического нагрева и охлавдени , например роликов , подов печей, корзин, звеньев ленточных конвейеров термических печей и других печных инструментов.The invention relates to ferrous metallurgy, in particular, to the composition of chromium-nickel austenitic steel with carbide hardening, which has increased heat resistance at a temperature of 1000-1200 ° C, for the manufacture of parts operating under conditions of periodic heating and cooling, such as rollers, pallets of furnaces, baskets conveyor belts of thermal furnaces and other oven tools.
Цель изобретени - повышение жаростойкости и эксплуатационной стойкое- ти стали при 1000 - 1200°С.The purpose of the invention is to increase the heat resistance and serviceability of steel at 1000 - 1200 ° C.
В табл. 1 приведен химический состав опытных плавок сталей.In tab. 1 shows the chemical composition of the experimental heats of steel.
Испытани жаростойкости и эксплуатационной стойкости провод т непо- : средственно в производственных услови х на проходных толкательных электропечах при температуре 1000 - 1200 с и времени вьщержки в печи 4 ч. Ллительность одного термоцикла состанп - ет 10 ч.The tests of heat resistance and operational durability are carried out directly: directly in the production conditions on the pusher electric furnaces at a temperature of 1000 - 1200 s and a furnace holding time of 4 hours. The duration of one thermal cycle is 10 hours.
Жаростойкость определ ют по потере массы металла печным инструментом при времени окислени 100 ч и температуре 1000, 1100 и 1200 с, мг/см.Heat resistance is determined by the weight loss of the metal with a kiln instrument with an oxidation time of 100 hours and temperatures of 1000, 1100 and 1200 s, mg / cm.
Эксплуатационную стойкость определ ют по количеству теплосмен до по влени трещин разгара и по ширине TpenpiH разгара в напр женных местах.The operational durability is determined by the number of heat changes before the occurrence of height cracks and the width TpenpiH of height in tension places.
В табл. 2 приведены свойства стали.In tab. 2 shows the properties of steel.
Из данных табл. 2 следует, что жаростойкость и эксплуатационна стойкость предлагаемой стали превьшают соответственно в 2,0 - 2,2 раза и 1,4 - 1,6 раза свойства известной стали.From the data table. 2 it follows that the heat resistance and operational resistance of the proposed steel exceed, respectively, 2.0-2.2 times and 1.4-1.6 times the properties of the known steel.
