對(duì)原材料的標(biāo)記，從一開始便應(yīng)十分注意。標(biāo)定的內(nèi)容包括材料牌號(hào)、爐批號(hào)、收發(fā)貨日期和供應(yīng)廠的代號(hào)等。這樣做有助于區(qū)別材質(zhì)的變異是由于制造過(guò)程本身的因素引起;還是由于非制造過(guò)程的因素引起。原材料有了標(biāo)記，也能為評(píng)價(jià)供應(yīng)廠的產(chǎn)品質(zhì)量提供可靠的依據(jù)。

　　Attention should be paid to the marking of raw materials from the beginning. The contents of the calibration include material grade, batch number, delivery date and code of the supply plant. This helps to distinguish between material variations due to factors in the manufacturing process, or from non manufacturing processes. The raw material has the mark, but also can provide the reliable basis for evaluating the product quality of the supply factory.

　　重要鍛件的標(biāo)記包括零件號(hào)、爐批號(hào)、鍛造日期和承制廠記號(hào)等，應(yīng)將其在生產(chǎn)中逐件檢查記錄下來(lái)，以便在使用過(guò)程中一旦發(fā)生問(wèn)題，可以用來(lái)幫助查找原因和確定責(zé)任者。標(biāo)記在鍛件上打印的部位，應(yīng)是鍛件容易發(fā)現(xiàn)的地方。如果鍛件上的印記在機(jī)械加工時(shí)會(huì)被切削掉，那末在車間的生產(chǎn)過(guò)程中，在這個(gè)鍛件裝配完畢或用打印模等其它方法重新作出標(biāo)記前，應(yīng)掛上金屬標(biāo)簽，以免混亂。

　　Mark key forgings include part number, batch number, date and forging supplier mark, it should be in production by piece inspection records, in order to use in the process of the event, can be used to help find the reasons and determine responsibility. The mark on the part of the forging shall be the place where the forging is easy to find. If the mark will be forging cutting off in machining, the end of the workshop in the production process, in the forging assembly line or print mode and other methods to make mark before, should be hung metal labels, in order to avoid confusion.

　　鍛件質(zhì)量控制是對(duì)生產(chǎn)中的可變參數(shù)和鍛件的幾何尺寸、表面質(zhì)量和力學(xué)性能進(jìn)行定期的測(cè)定和檢驗(yàn)。并將測(cè)得的結(jié)果與標(biāo)準(zhǔn)和技術(shù)條件要求進(jìn)行比較，以便決定是否有必要去改變鍛件生產(chǎn)過(guò)程中的某些因素，實(shí)現(xiàn)對(duì)鍛件質(zhì)量的控制，保證鍛件最終質(zhì)量的波動(dòng)不超出訂貨單位技術(shù)條件的要求。

　　The quality control of forgings is a regular measurement and verification of the variable parameters and the geometric dimensions, surface quality and mechanical properties of the forgings. And the measured results and standards and technical requirements are compared, in order to decide whether it is necessary to change some of the factors in the process of forging production, to achieve control of the forging quality, ensure the final quality of forgings fluctuation does not exceed the technical conditions of the units ordering requirements.
