Description
Изобретение относитс к металлургической промышленности, в частности к смазке дл гор чей обработки металлов при производстве труб.The invention relates to the metallurgical industry, in particular to a lubricant for the hot treatment of metals in the manufacture of pipes.
Известна смазка, представл юща собой водную суспензию графита. Однако качество обрабатываемой поверхности не удовлетвор ет предъ вл емым требовани м, так как происходит налипание металла на инструмент.A known lubricant is an aqueous suspension of graphite. However, the quality of the surface to be treated does not meet the requirements, since metal is sticking to the tool.
С целью устранени указанного недостатка предлагаетс в состав смазки вводить полиакриламид .In order to eliminate this drawback, polyacrylamide is introduced into the composition of the lubricant.
Смазка состоит (в вес. %):The lubricant is (in wt.%):
Иолиакриламид8-10Ioliacrylamide 8-10
Графит30-35Graphite 30-35
ВодаОстальноеWaterEverything
Проведение анализов на содержание вредных веществ в атмосфере показало полное отсутствие токсичных веществ. В атмосфере содержатс : пыль 2 СО, С1 не обнаружены; NHs 1,3 мг/м.Testing for the content of harmful substances in the atmosphere showed a complete absence of toxic substances. The atmosphere contains: dust 2 CO, C1 not detected; NHs 1.3 mg / m.
Смазка готовитс механическим смещением графита и раствора полиакриламида. Полиакриламид в воде раствор етс путем подогрева до температуры 50-60° С.The lubricant is prepared by mechanical displacement of graphite and polyacrylamide solution. Polyacrylamide is dissolved in water by heating to a temperature of 50-60 ° C.
Полиакриламид вводитс дл прочного сцеплени смазки с поверхностью прокатного инструмента. В противном случае происходит отщепление графита и налипание металла трубы на инструмент.Polyacrylamide is introduced to firmly adhere the lubricant to the surface of the rolling tool. Otherwise, the graphite is split off and the metal of the pipe sticks to the tool.
К тому же сам по себе полиакриламид обладает хорошими смазочными свойствами.In addition, polyacrylamide itself has good lubricating properties.
