1．伪劣钢材易出现折叠。折叠是钢材表面形成的各种折线，这种缺陷往往贯穿整个产品的纵向。济钢一级代理产生折叠的原因是由于伪劣厂家追求高效率，压下量偏大。

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．伪劣钢材外表经常有麻面现象。麻面是由于轧槽磨损严重引起钢材表面不规则的凹凸不平的缺陷。由于伪劣钢材厂家要追求利润，经常出现轧槽轧制最超标。

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．伪劣钢材表面易产生结疤。原因是伪劣钢材材质不均匀，杂质多。伪劣材厂家导卫设备简陋，容易粘钢，这些杂质咬人轧辊后易产生结疤。

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．伪劣材表面易产生裂纹，原因是它的坯料是土坯，土坯气孔多，土坯在冷却的过程中由于受到热应力的作用，产生裂痕，经过轧制后就有裂纹。

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．伪劣钢材容易刮伤，原因是伪劣材厂家设备简陋，易产生毛刺，刮伤钢材表面。深度刮伤降低钢材的强度。

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．伪劣钢材无金属光泽，呈淡红色或类似生铁的颜色，它的坯料是土坯，伪劣材轧制的温度不标准，他们的钢温是通过目测的，这样无法按规定的奥氏体区域进行轧制，钢材的性能自然就无法达标。

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.
