With the individuation demand of cold-drawing machine, every cold-drawing machine manufacturer needs to adopt scientific, advanced and fast design method to quickly meet the needs of users. With the increasing number and variety of cold-drawing machines, the enterprises that manufacture cold-drawing machines urgently need industry standards to standardize the production of cold-drawing machines to achieve standardization and universality. The industrial production and practice in the past 20 years show that it is advanced and reliable to directly produce pipes for hydraulic pneumatic cylinders by cold drawing process, and it has higher economic value and social benefit. The production of cold drawing machine will develop towards high precision, heavy duty, automation and green safety. The prestressed frame type hydraulic cold drawing machine will be the future development direction, and the cold drawing machine will be serialized and standardized.
With the increasingly fierce competition, the profit margin of the steel market is getting lower and lower, and the price transparency is increasing. Only with high precision can the high profit be obtained. China's seamless steel tube production and consumption ranks first in the world, and seamless steel tube production is second only to Tianjin and Jiangsu. Corresponding to this situation, the city's steel pipe production mainly seamless pipe, but also part of the welded pipe, the output ranks first in Shandong. The two is variety. Each steel pipe market has all kinds of stock, specifications and specifications, and there are more than 10 thousand models. There are many steel pipe production and processing enterprises. The products include cast pipe, cold drawn pipe, finish rolled pipe, hot expansion pipe, straight welded pipe, honing pipe, etc. The caliber ranges from 5 mm to 1200 mm, and can be customized for customers at any time.
Honing pipe industry actively promotes technological progress, product innovation, energy conservation and emission reduction. Since the commissioning of Bayuquan honing pipe New District in Angang, the coke ratio and PCI ratio of blast furnace have been greatly improved. Shougang Jingtang honing pipe company 5500 cubic meters of blast furnace dry dedusting and seawater purification reached international level. In the first 11 months of 2009, the energy consumption and sulphur dioxide emissions of the honing tube industry decreased. With the influx of a large number of products, the supply of stainless steel honing tube market is far greater than the demand. The price keeps falling, which makes many experts in the industry short of the honing tube price. The industry expansion impulse gradually stops as the market price drops. In the view of the industry, the development of the honing tube industry should be deeply reformed and directly cut in. Substantive issues to remove key issues.
Taking the West-to-East Gas Pipeline Project as an example, if the steel pipe usage of the trunk line is 1.72 million tons and the medium-pressure pipeline to be laid and distributed to the users after the natural gas enters the city is all polyethylene gas pipeline, it will need nearly 2 million tons. Therefore, the market capacity of the pipeline is huge. Precision cold-drawn steel pipe cold-drawn alloy pipe with small diameter is cold-drawn. Extubation steel tube and high pressure boiler tube have broad prospects for development. Precision cold-drawn alloy pipe cold-drawn small-diameter cold-drawn steel pipe, high-pressure boiler pipe natural gas will become the main gas source of most large and medium-sized cities in the future. In 2005, 148 cities in China and 72 million people used natural gas with an annual gas consumption of 20 billion 200 million cubic meters. High precision cold-drawn aluminum alloy pipe is a new product developed in the 1990s by using high precision cold-drawn steel pipe production technology and equipment. Compared with cold-drawn steel pipe, it has the characteristics of light weight, smooth surface, low strength and easy to grind, and can gradually fill the gap between high-precision cold-drawn steel pipe and low strength.
