The Development of Metallurgical Industry

The so-called metallurgical industry refers to the industrial departments of exploiting, selecting, sintering and smelting metal ore into metal materials. It can be divided into two aspects, namely black metallurgical industry, and nonferrous metallurgical industry. The black metallurgical industry refers to the industrial department that produces iron, chromium, manganese, and alloy, providing raw materials for modern industry, transportation, basic construction, and military equipment. While nonferrous metallurgical industry refers to the industrial departments which produce black metal such as copper smelting industry, aluminum industry, lead, and zinc industry, nickel and cobalt industry, smelting industry, precious metal industry, rare metal industry. The development of steel industry has obviously expanded since the 1980s. The international competitiveness of the steel industry has become fiercely by 1990s, and most enterprises shifted the development focus to consumption and costs reducing, varieties increasing, quality improvement, and environmental protection. Traditionally metallurgical industry is to work under the cold condition, and this condition has improved a lot in recent years. The steel industry has made obvious progress, which is embodied in the production procedure, technology optimization, quality improvement, ect..

 In the process of industrial production, the consumption of water in metallurgical production tend to be huge. At present, metallurgical enterprises in some countries usually adopt a circulative water supply system, which is convenient, high-efficient, and easy to manage. However, there are also shortcomings in this system. The main problem is that water usage is small while the water supply tends to be large. The composing of the water supply system is simple, adopting one pump for one machine method. In the process of production, there is a single water supply equipment in the circulative system for some metallurgical enterprises, which is difficult to meet the production needs. In addition, there are explicit water usage requirements in metallurgical production.  In this sense, the single water supply equipment can easily cause fault problems.


There are higher requirements for the basic performance of the equipment and the operative technique of workers in the metallurgical production. The drainage design in metallurgical production is a key component, which is directly related to the efficiency and level of metallurgical operation. The final design effect will be influenced because of low professional technology and overall level of skill. The basic water requirement is different because of the different water supply point. It will consume huge raw material and water resource in metallurgical production, which is harmful to the environment and energy-saving and emission-reduction. The water supply and drainage system design in the industrial field not only provides essential water resource for production but also promotes the reasonable operation of drainage works. The concept of water supply and drainage system includes two aspects, namely water supply and draining off water. After the industrial waste or sewage water being handled centrally, it should be re-utilized or discharged safely. However, relevant workers usually do not conduct an investigation for drainage point and lack the experience of sewage treatment, which will influence the energy-saving and emission-reduction work.     

The metallurgical enterprises should start with the energy-saving work from the following aspects: First, the metallurgical enterprises should deeply aware that the significance of adopting advanced energy-saving technology in the process of metallurgical production because advanced and mature technology is a kind of strategic thoughts and means to reduce production costs and improve market competitiveness. Secondly, the metallurgical enterprises ought to actively master the world’s advanced technology and introduce advanced manufacturing crafts and skills at present. Besides, they should also consider the problem of craft matching in the round and ensure the newly developed projects are all at a high point, including the aspects of technology and energy-saving. As for the backward crafts and equipment, they should be transformed or updated directly. The changes from energy-saving consumption of the single equipment into the energy-saving consumption of the system should be realized step by step. Thirdly, metallurgical enterprises should combine the introduction of advanced technology with their actual situation. When applying advanced energy-saving technology, the enterprises should selectively adopt advanced equipment and crafts instead of blind investment which leads to idle equipment and source waste. Fourthly, the enterprises should increase the investment in science and technology, and continue to research the energy-saving problem in the new enterprises. Besides, the technology should be combined with the second innovation in order to shape the independently energy-saving technological system.


Specialized crushing equipment should be utilized to crush the metallurgical materials. The roll crusher produced by HXJQ machinery is widely used in metallurgical industry, building materials, refractory materials and other medium and high materials. This kind of crusher is characterized by low noise, little stive, reliable performance, and convenient to repair. Besides, the roll crusher for sale produced by HXJQ China can also play an environment-friendly effect. The products after crushing will present cubic appearance, and the needle-like content is low. There is no internal crack, and the discharge size is fine, which improves product quality and efficiency. The cycle of rolling is long and the loss is small, which will bring remarkable economic benefits.
