A damaged mold, as long as it is covered with a layer of special material at the damage, and then used a laser, it can be put into production again. Ninghai Shengyuan Laser Technology Co., Ltd. relied on this “exclusive survival†to “restore†more than 50 million yuan worth of scrapped molds and rolls within a year.
“There are various types of rolls and molds on industrial equipment. The materials and hardness of each type are different. It is not easy to find matching raw materials. For this reason, scrapped parts are generally discarded directly.†The person in charge of Shengyuan Company encountered it. After this situation: The mechanical equipment of a Taiwan-funded enterprise was damaged due to two rollers, and the origin of the machine was temporarily out of stock. As a result, the company stopped production for more than a month and lost four or five million yuan.
Shengyuan Company solved the problem of "missing" raw materials. The technician first analyzes the raw materials of the damaged parts, and then mixes them with appropriate ratios from hundreds of raw materials such as iron and magnesium, and melts into a special material that approximates the raw materials. In addition, Shengyuan Company also introduced a laser worth 30 million yuan from Germany to cover the damaged material to the damaged surface. Compared with traditional plating, flame surfacing and other repair technologies, laser cladding can achieve full integration of raw materials.
"Copying" raw materials is not an easy task. Shengyuan company technical personnel said that the ratio of each element can not be biased. On one occasion, when they studied the roll material with a hardness of 58 degrees, the iron powder dose was 1 gram more, and the raw materials produced were easily cracked.
The laser cladding process also saves companies money. A rolling mill in Ninghai scrapped 45 or more rolling pipes every month, each of which was priced at RMB 4,000 to RMB 5,000. Now with Shengyuan's new process, only 10% to 30% of the rolling tube cost is required. In less than an hour, the “old pipe†can be changed to “new pipeâ€. It is understood that Shengyuan’s roll repair business of only 5 small steel mills that it took last year saved these companies more than 5 million yuan in expenditure.
Some experts in Beijing, after examining the Shengyuan company, said that the quality of the molds and rolls that are repaired by the laser is not lower than the original product.
