Dhagaxshiidka Rolling: taariikhda iyo dirka casri ah

dhagaxshiidka A diidanaa sida qalab loogu talagalay habsocodyada Biraha iyo qalabka kale ee qoqobada dhowr cadaadis duudduuban waxaa marka hore u soo sheegnay in shuqullada Leonardo da Vinci. hab ay ugu da'da weyn ku tilmaamay by sayidkii weyn ee 1495, loogu talagalay daaweynta iyo waxa daasadda. qalabka Rolling ayaa waxaa durbaba si weyn loo isticmaalaa in Qarnigii 17aad, halkaas oo ay ka soo shaqeeyay ku saleysan actuators buugan, kuwaasi oo ay ka dib bedelay biyo (wheel oo biyo ah), ka dibna si uumi. Maanta, qalabka kiro la drive gacanta waxaa badanaa loo isticmaalaa shaqada farsamada gacanta.

dhagaxshiidka A diidanaa sida qeyb ka mid ah qalabka ay leedahay jidhka ugu weyn (ku taaganyihiin shaqeeya, taas oo u dhaxayn kartaa laba ilaa duub oo dhowr ah, korontada iyo aaladaha, gudbinta awood u rollers of engine ah) iyo kaabayaal (Qalabka dhaqdhaqaajin workpieces, ay goynta, toosinta, garkooda, iwm ) .. Qorshahaa waxa ka mid ah qalab gaar ah ku lifaaqan nooca sheyga, kaas oo la sii daayay.

waxyaabaha soo giringiriyey, taas oo ku xidhan nooca cross-qaybta u qaybsan yahay kooxo dhowr ah, oo ay ku jiraan:

- biibiile (xuduud lahayn ama ay fuliyeen alxanka);

- sheet giringiriyey (sheet khafiif ah ama saxan giringiriyey (4 mm));

- giringiriyey (Caraabaah ama u qaabeysan);

- rogid gaar ah (angular C-qaabeeya, la profile a variable, iwm).

dhagaxshiidka rogid sida ay nooca badeecada ahaan loogu talo galay mid ka mid ah kooxaha soo socda: dhuumaha, lento-, zhesteprokatnye, gaar ah, sheet, silig, shtripsovye, broadband, tayo sare leh, crimping (badanaa ubaxu), billet, dhagax diidanaa. Qalabka noocan ah waa weyn. Tusaale ahaan, marka laga reebo dhagax wax yar ku yeelan karaan dheer ah shan iyo toban mitir, oo ugu weyn in nuqul taariikhda dheer ee degan 5,500 mitir (ay leedahay "Anshen geedka kokaha Iron Steel Group").

Qoondaynta oo ah ku daqiijin jireen on sifooyinka design sida soo socota:

- a hal (ay ka kooban waa shaqabaq, qabsiyo, tusaale ahaan, lix matoorrada korontada, shantii saxiixdaan, afar gearboxes saddex taribuunka marsho size iyo laba spindles);

- toosan dhagax rogid (taagan waxaa lagu abaabulaa ka mid kale ka dib markii, mararka qaarkood in khadadka kala duwan, waxyaabaha baaraandegi in hal jiho);

- serial (dhowr daqiijin jireen hal-taagan diyaarin sequentially ama si ka duwan);

- joogto ah (billet baaraandegi isku mar in tiro ka mid ah baqashada);

- semi-joogto ah (waxaa jira qaybaha joogto ah iyo qaybaha hardware toosan).

Sidee dhagax? First, ingot biraha la kululeeyo in ceelal gaar ah (heer kulka oo ku saabsan 1800 C), oo korkoodana waxaa samatabbixiyaa gaariga korontada si processing ugu muhiimsan (ee ubaxu ama slabbing) diidanyihiin ingot la helay gudban. Next, mid ka mid ah oo ku saabsan nooca qalabka xaashiyo kale biraha rogid diyaariyey ama soo saarka dhammeeyey qaab loo dejiyay, sida xadiidka ah, iyo kuwa kale. Qalabka casriga ah sida caadiga ah waa ku daqiijin jireen ah oo loo shubay-diidanaa in ka arrinsashada kartaa workpiece ee tarabuunka xawaare ah oo ku saabsan 300 km saacadiiba.

Production ee ku daqiijin jireen diidanaa waa geedi socod adag oo qaali ah, weli maanta waxaa jira shirkado ee Russia in ay soo saaraan waxyaabaha sida. Intaa waxaa dheer in ay ugu weyn iyo qalabka kaabayaal ah hawlgalka guul adag ee u baahan tahay qalab-sax sare, qalabka sifaynta, iyo sidoo kale bixinta adeeg koronto in ay ku daqiijin jireen oo leh awood a total of 200-300 MW.
