Why is there scar on the surface after the chain is used for a period of time, is the quality not up to standard and is it fake? In fact, it is not. China chain supplier(GETECHAIN) https://www.getechain.com/ will tell you what this is all about. These scars are generally on the surface and are one or more pits with irregular shapes, different materials, different scales of probability, and the probability of scar formation of steel, low alloy steel, and high strength steel is higher than that of ordinary carbon steel. There are usually two reasons: 1. During the use of the chain, the head and tail of the slab will return slag to the product chain. When the steel slag is serious, it can form a compact and firmly attached to the blank area table. Steel slag is the accumulation of metal flowing in the casting blank, which is blown away by the wind during cutting but overflows along the incision and forms at one end of the blank table. Cause analysis of slag on the bench area: improvement of low-pressure oxygen purity, inappropriate or fluctuating cutting life; Later, it expanded. Different kinds of steel, chain conveyor with cut-off panel, incorrect speed setting of cutting trolley, and deterioration of cutting effect. 2. Usually, the position of photoelectric detection plate, automatic landing control rotary burring machine, hammer head, and tail billet continuous casting. Burrs cannot be cleaned cleanly, and then during the rolling process, the chain will produce some scars. Click China chain factory https://www.getechain.com/ to learn about more information.
