1．偽劣鋼材易出現(xiàn)折疊。折疊是鋼材表面形成的各種折線，這種缺陷往往貫穿整個(gè)產(chǎn)品的縱向。濟(jì)鋼一級(jí)代理產(chǎn)生折疊的原因是由于偽劣廠家追求高效率，壓下量偏大。

1. the fake and inferior steel is easy to fold up. Folding is a variety of broken lines formed on the surface of a steel, which often runs through the longitudinal direction of the whole product. The reason for the folding of the first class agent in Jigang is due to the high efficiency of the fake and inferior manufacturers and the large reduction.

2．偽劣鋼材外表經(jīng)常有麻面現(xiàn)象。麻面是由于軋槽磨損嚴(yán)重引起鋼材表面不規(guī)則的凹凸不平的缺陷。由于偽劣鋼材廠家要追求利潤(rùn)，經(jīng)常出現(xiàn)軋槽軋制最超標(biāo)。

2. inferior steel appearance often pitted phenomenon. Ma is due to a defect of groove wear caused by irregular rugged steel surface. Because the counterfeit and inferior steel manufacturers want to pursue profit, it often appears that the groove rolling is the most super standard.

3．偽劣鋼材表面易產(chǎn)生結(jié)疤。原因是偽劣鋼材材質(zhì)不均勻，雜質(zhì)多。偽劣材廠家導(dǎo)衛(wèi)設(shè)備簡(jiǎn)陋，容易粘鋼，這些雜質(zhì)咬人軋輥后易產(chǎn)生結(jié)疤。

3. the surface of fake and inferior steel is easy to produce scars. The reason is that the material of the fake and inferior steel is not uniform, and the impurity is much. The fake and inferior materials manufacturers guide the equipment simple, easy to stick to steel, these impurities bite the roll after easy to produce scars.

4．偽劣材表面易產(chǎn)生裂紋，原因是它的坯料是土坯，土坯氣孔多，土坯在冷卻的過(guò)程中由于受到熱應(yīng)力的作用，產(chǎn)生裂痕，經(jīng)過(guò)軋制后就有裂紋。

4., the cracks on the surface of the fake and inferior materials are easy to cause cracks. The reason is that the billets are adobe and there are many holes in the adobe. During the cooling process, the adobe is cracked due to the thermal stress, and there are cracks after rolling.

5．偽劣鋼材容易刮傷，原因是偽劣材廠家設(shè)備簡(jiǎn)陋，易產(chǎn)生毛刺，刮傷鋼材表面。深度刮傷降低鋼材的強(qiáng)度。

5. the fake and inferior steel is easy to scratch. The reason is that the equipment of the fake and inferior material is simple, the burr is easily produced and the surface of the steel is scratched. Deep scraping reduces the strength of the steel.

6．偽劣鋼材無(wú)金屬光澤，呈淡紅色或類似生鐵的顏色，它的坯料是土坯，偽劣材軋制的溫度不標(biāo)準(zhǔn)，他們的鋼溫是通過(guò)目測(cè)的，這樣無(wú)法按規(guī)定的奧氏體區(qū)域進(jìn)行軋制，鋼材的性能自然就無(wú)法達(dá)標(biāo)。

6. inferior steel metal luster, reddish or similar iron color, it is entirely adobe, shoddy material rolling temperature is not standard, their steel temperature is through the visual, so according to the provisions of the austenite region of rolling steel performance naturally can not be up to the standard.
