Description
Изобретение относитс к производству огнеупорных изделий, в частности - огнеупорных тиглей, фильер и др., используемых в металлургической промышленности.The invention relates to the production of refractory products, in particular refractory crucibles, dies, etc., used in the metallurgical industry.
Целью изобретени вл етс повышение срока эксплуатации изделий за счет повышени стойкости изделий в расплаве, упрощение процесса и исключение выделени соединений хлора в процессе обработки .The aim of the invention is to increase the life of the products by increasing the resistance of the products in the melt, simplifying the process and eliminating the release of chlorine compounds during processing.
Поставленна цель достигаетс тем, что в способе обработки огнеупорных изделий дл разливки сплавов, включающем шлифовку и обработку в среде углеродсодержа- щих газов при нагревании, обработку огнеупорных изделий ведут в среде метана или природного газа при температуре 800- 1000°С, а шлифовку до окончательных размеров осуществл ют перед обработкой в среде метана или природного газа.This goal is achieved in that in a method for processing refractory products for casting alloys, including grinding and processing in a carbon-containing gas medium when heated, refractory products are processed in methane or natural gas at a temperature of 800-1000 ° C, and grinding to final sizes are carried out before being treated in methane or natural gas.
При этом обработку изделий из двуокиси кремни в среде метана или природного газа провод т в течение 1-10 часов.In this case, the processing of silicon dioxide products in methane or natural gas is carried out for 1-10 hours.
Пример 1. Щелевую фильеру (диаметр 70 мм, щель 30 х 1 мм) из керамикиExample 1. Slotted die (diameter 70 mm, slot 30 x 1 mm) made of ceramic
двуокиси кремни предварительно шлифуют алмазным инструментом до конечных размеров. Фильеру помещают в реактор и обрабатывают в среде природного газа при температуре 900°С в течение 4 ч Фильеру использовали дл плавки и разливки спл за алюминий-литий. Фильера выдержала 7 плавок. Качество металла хорошееsilicon dioxide is pre-ground with a diamond tool to final dimensions. The die was placed in a reactor and treated in natural gas at a temperature of 900 ° C for 4 hours. The die was used to melt and cast alloys for aluminum-lithium. Diera withstood 7 swimming trunks. Good metal quality
Примеры 2-6 Обработку фильер провод т аналогично. Услови обработки и свойства фильер представлены в таблицеExamples 2-6 Processing of spinnerets is carried out similarly. The processing conditions and properties of the dies are presented in the table
