Nowadays, high chrome ball casting at constant temperature has been compared with traditional manual casting. Each of them has its special features. Then, let's introduce in detail high chrome ball casting at constant temperature compared with traditional manual casting.
Here is the content list:
l High chrome ball casting at a constant temperature
l Traditional manual casting
l Characteristics
High chromium balls cast from casting at constant temperature production lines have great advantages over traditional manual casting. The parabola of casting is only 10 cm, which ensures casting in an almost constant temperature range, ensures that the temperature difference changes little during molten iron casting, and improves the comprehensive performance of high chromium ball. In addition, different casting temperature is used to control the high chromium ball with different materials and specifications, thus ensuring the stability of high chromium ball quality. However, the temperature of the cast high chromium ball can not be grasped in real-time during manual casting, which makes it difficult to reach the prescribed level of the related technical indexes of the high chromium ball produced. High chromium balls use a casting at a constant temperature to ensure the quality of high chromium balls produced stable, high chromium ball casting process document real-time control, ensure that the temperature difference is less than 30 degrees, casting process mechanization to ensure the production of high chromium balls, Greatly reduce the probability of molten iron spatters injury to operators.
Due to the use of manual casting, the high chromium ball produced by similar manufacturers can not guarantee the casting at constant temperature due to time problems, the temperature of casting is high, and the temperature of post-casting is low, especially in winter. The temperature difference is more than 100 degrees. The upper layer of molten iron usually floats a layer of iron slag. If directly cast, the slag will appear inside the high chromium ball, and the bottom leakage casting is used to ensure that there is no slag inside the high chromium ball. The hardness of a high chromium ball is small. Reduce the use of high chromium ball in the process of the spalling and crushing rate of high "apple" ball and other unqualified phenomena. In traditional manual production, ladle dumping casting is used, and no filter net is placed above the casting port, which leads to the direct dumping of ash floating in the upper layer of molten iron into the high chromium ball. The hardness difference and low service life of high chromium ball aggravate the breakage rate of high chromium ball.
Real-time monitoring temperature, casting at a constant temperature to ensure the stability of high chromium ball quality. Drip casting to avoid slag inclusion inside the sphere. Further control of slag by placing a filter net over the gate. The advanced casting at constant temperature produces the high chromium sphere smooth, the internal and external hardness difference is small, the high wear resistance, the high toughness, high hardness, low crushing rate, are produced by hand casting high chromium ball can not be compared. The low grinding energy consumption reduces the daily ball loading of the mill, and the low crushing rate can protect the service life of the lining plate of the mill and respond to it. National energy conservation and emission reduction normal, reduce production costs, enhance enterprise development space.
Above all is all about high chrome ball casting at constant temperature compared with traditional manual casting. Hope it will help you.
