Cold-drawn tube is a kind of cylinder barrel, compared with other processing technology, Cold-drawn Tube processing precision is higher, processing procedures are also many, so it is natural that cold-drawn tube is more expensive than cold-drawn tube. With the disorderly expansion of stainless steel cold-drawn pipes, the profits of the cold-drawn pipes industry will continue to decline, which will lead to the death of a large number of enterprises. According to the data of China Cold-drawn Pipes Industry Association, the profit margin of the cold-drawn pipes enterprises is only 0.4%, and this profit margin will decline if the industry continues to develop. The future development of stainless steel cold drawn pipe industry is worrying. Thus it can be seen that although blind expansion meets the market demand in the early period and reaches a certain balance between supply and demand, the funds invested in a short period of time can not be withdrawn quickly. Many enterprises will stagnate after entering the stainless steel cold-drawn pipe industry. Especially in the case of falling prices, the losses will become increasingly serious, and the interest on loans will be increased. The profit margin has been far higher.
Cold drawn pipe industry actively promotes technological progress, product innovation, energy conservation and emission reduction. Since the commissioning of Bayuquan cold drawn pipe New District, the coke ratio and PCI ratio of BF ironmaking have been greatly improved. The dry cleaning and seawater purification of the 5500 cubic meter blast furnace of Shougang Jingtang cold drawing pipe company has reached the international level. High grade silicon steel has been replaced by WISCO and Baosteel. In the first 11 months of 2009, the energy consumption and sulphur dioxide emissions of the cold drawn pipe industry decreased. At present, the development trend of cold-drawn pipe industry is realized under the background that the international cold-drawn pipe market continues to be depressed, the export of cold-drawn pipe is blocked, and the import impact is not small, and the market uncertainties are still many, which is really hard to come by. Therefore, China's precision cold-drawn pipe manufacturing industry should strengthen integration in its own field, there is no need for excessive competition, the division of labor and cooperation in technological development, the relevant industries and enterprises should take a long-term view, concentrate on new technology and new process research, and gradually form a division of labor, cooperation, multi-field, all-round. The research and development pattern has introduced the precision cold drawn tube products with independent intellectual property rights.
In recent years, plastic (emery) mixed pressing of honing workers, broaching companies suggest: according to different purposes can be suppressed in various shapes, so that honing can not only be used for processing internal holes, but also for processing cylindrical, plane, spherical and various special surface, such as cylindrical surface honing tools for cylindrical honing, gear honing wheel With abrasive gear. The cold drawing pipe is a honing head made of 4~6 sand bars for finishing the inner hole. Stainless steel basket company reminds: honing not only high productivity, but also high machining accuracy, general dimensional accuracy can reach IT5-IT6, surface roughness can reach 0.8-0.1 micron, and can correct the geometric deviation of the hole. In order to further improve the honing productivity, the honing technology is developing towards the direction of strong honing, automatic honing with automatic size control, electrolytic honing and ultrasonic honing.
The development of Cold-drawn Tube Industry in recent years has mainly benefited from the support of the state's export tax rebate policy. A large number of domestic output capacity is oriented to the international market. At this time, everyone can peacefully coexist with each other. After 2007, the drawbacks of excess capacity of domestic derivative tubes have been highlighted, and the export side has been suppressed by the policy. The domestic market has become a battleground for many manufacturers. In a series of measures, price war is often the most common and effective weapon, but this can not fundamentally solve the problem, but disrupt the market order. Therefore, with the help of the industry crisis, steel mills to increase efforts to shuffle the industry can also be regarded as one of the reference reasons for the emergence of the market. Price rises and falls are the secondary risk factors affecting the operation of enterprises. The first one is the capital chain. At present, many enterprises in the stainless steel industry are facing the problem of capital chain breakage.
