Description

Nizej opisany piec sluzy do spawania kawalków stali szybkotnacej z trzonkami stalowymi, uzywanymi przy obróbkach na tokarniach.Piec zbudowany jest z cegly szamoto¬ wej i opancerzony blacha zelazna. Piec u- ruchomia sie w nastepujacy sposób: do ko¬ mory spalinowej 1 wklada sie pare kawal¬ ków wegla drzewnego, rozzarzonego, na który wpuszcza sie sprezone powietrze rur¬ ka 2; po takim nagrzaniu komory 1, wpu¬ szcza sie dysza 3 rope, rozpylona sprezo¬ nym powietrzem. Plomien ropy przecho¬ dzi przez komory 4 i 5, nastepnie kanalem 6 uchodzi do komina; u wylotu kanalu 6 wbudowana jest rurka 7, która przechodzi sprezone powietrze do dyszy podgrzewajac sie, aby przy rozprezaniu nie obnizylo tem¬ peratury palacej sie ropy. Przygotowane trzonki stalowe z kawalkiem stali szybko¬ tnacej, miedzy którymi umieszczony jest specjalny proszek, wklada sie do komory 5, gdzie podgrzewaja sie one do tempera¬ tury okolo 800°C, nastepnie przeklada sie podgrzewana stal do komory 4, w której temperatura wynosi okolo 1300°C. Po pa¬ ru sekundach stal szybkotnaca^ proszek i trzonek stalowy rozgrzewaja sie do tem¬ peratury, przy której zaczynaja sie topic.Wi tym momencie wyjmuje sie calosc z ko¬ mory 4, wklada sie pod prase, pod która laczy sie stal szybkotnaca z trzonkiem sta¬ lowym; na koniec gotowy nóz tokarski z pod prasy poddaje sie hartowaniu w stru¬ mieniu wyplywajacego sprezonego po¬ wietrza. PLThe furnace described below is used to weld pieces of high speed steel to steel shanks used in turning operations. The furnace is made of fireclay bricks and armored sheet iron. The furnace is activated as follows: a few pieces of glowing charcoal are put into the flue gas chamber 1, into which compressed air is introduced through a tube 2; after chamber 1 has been so heated, a rope nozzle 3, sprayed with compressed air, is released. The oil flame passes through chambers 4 and 5, then through channel 6 to the chimney; at the outlet of the channel 6, a tube 7 is built in, which passes the compressed air to the nozzle and heats it up so that it does not lower the temperature of the burning oil during expansion. The prepared steel shanks with a piece of high-speed steel, between which a special powder is placed, are put into chamber 5, where they are heated to a temperature of about 800 ° C, then the heated steel is transferred to chamber 4, where the temperature is about 1300 ° C. After a few seconds, the high-speed steel, the powder and the steel handle heats up to the temperature at which the topic begins. At this point, the whole thing is taken out of chamber 4, put under the press, under which the high-speed steel is connected with the handle steel; Finally, the finished lathe tool from the press is quenched in a jet of compressed air.
