Kodi scraper blade imapangidwa ndi chiyani?

Wolfram carbide

Tungsten carbide ndi gulu lopangidwa ndi 50% tungsten ndi 50% kaboni. Pali njira zingapo zomwe zimagwiritsidwa ntchito popanga chigawocho, chofala kwambiri chomwe chimagwirizanitsa zitsulo za tungsten ndi carbon pa kutentha kwa 1400 mpaka 2000 ° C. madigiri Celcius.

Zitsulo zothamanga kwambiri

Chitsulo chothamanga kwambiri (HSS) ndi aloyi yomwe imaphatikiza chitsulo (chitsulo ndi carbon) ndi zinthu zina monga chromium, molybdenum, tungsten, vanadium kapena cobalt. Zinthu zina kupatula zitsulo zimatha kupanga 20% ya kapangidwe ka HSS, koma nthawi zonse zimapitilira 7%.

Kuwonjezera zinthu izi zitsulo si zokha kupanga HSS, zinthu ayeneranso kutentha mankhwala ndi kupsa mtima.

Chitsulo chothamanga kwambiri (HSS) chimatha kudula zinthu mwachangu kuposa chitsulo cha carbon, motero amatchedwa "liwiro lalikulu". Izi ndichifukwa cha kuuma kwake kwakukulu ndi kukana kwa abrasion poyerekeza ndi carbon high ndi zida zina.

Chifukwa chiyani zitsulo zothamanga kwambiri ndi carbide zimagwiritsidwa ntchito popanga scraper?

Tsamba la scraper liyenera kupangidwa ndi chinthu cholimba kuposa chinthu chomwe chikukucha kuti chigwire ntchito. Zowonjezera zowonjezera zowonjezera ndi njira zopangira, monga chithandizo cha kutentha chomwe chitsulo chothamanga kwambiri chimayikidwa, chimapereka kuuma kofunikira pakukakula.

Carbide scrapers ndizovuta kuposa HSS. Izi zimawathandiza kuti azigwiritsidwa ntchito pazinthu zambiri.

Zosakaniza zosasinthika

Masamba osasinthika osasinthika amakhala pafupifupi nthawi zonse amapangidwa ndi chitsulo chothamanga kwambiri, popeza mtengo wopangira tsamba lonse ndi shaft kuchokera ku carbide ungakhale wokwera kwambiri.

Ngakhale masamba osasinthika amapangidwa ndi chitsulo chothamanga kwambiri, gawo laling'ono lokha kumapeto kwa scraper ndi kutentha ndi kutentha. Malo otenthetsera kutentha ndi kutentha nthawi zambiri amasiyana ndi mtundu wonse wa shaft.

Ndi zipangizo ziti zomwe scraper blade zingagwiritsidwe ntchito?
