Several questions to know when designing non-standard equipmentTime of issue : 2021- 11-22
No matter what type of product is trying to capture a larger market, it needs to perform well. The factors that affect the performance of the product are closely related to the production process, and of course the design of the product is also important. The same is true for non-standard equipment and other products. Before being put into production, a very clear design concept is required to determine the style and connotation of the product. In order to design and manufacture non-standard equipment suitable for modern industrial development, several principles need to be followed in the design and production process. 1. Beautiful appearance of the machine Everyone likes products with better appearance, which is also the primary impression of consumers when choosing. Under the same conditions of other performance, consumers will definitely choose non-standard equipment with more beautiful appearance when choosing. 2. Make sure the machine is easy to use One of the main reasons for using non-standard equipment for production is convenience, but if the production equipment is very cumbersome, complex, and maybe even more laborious than manual production, then this product is definitely not suitable for consumers. Therefore, in order to develop non-standard equipment that is simple to operate and easy to use, it is required by all users. 3. Reasonable structure and convenient disassembly and assembly During the use of the machine, failures will inevitably occur, and the equipment needs to be disassembled and repaired at this time. The well-designed structure is easy to disassemble and assemble, without wasting too much time, and it is easy to repair. The emergence of non-standard equipment liberates labor productivity, reduces our labor intensity, and reduces the labor input cost of enterprises, which is a manifestation of the improvement of scientific and technological level. Non-standard equipment with beautiful design and reasonable structure is the equipment that all consumers really want. Yicheng Machinery can manufacture various non-standard equipment according to user needs. If necessary, please call for cooperation.
Characteristics of wear-resistant lining plate for blast furnace roofTime of issue : 2021- 11-22
Features of blast furnace top wear-resistant lining plate:
(1) High wear resistance: The alloy system commonly used in the wear-resistant lining plate of the top of the international blast furnace is used, which has excellent wear resistance. The wear resistance is much higher than that of heat-treated wear-resistant steel and wear-resistant cast iron, and the wear resistance is also greatly improved. It is suitable for spray welding or thermal spraying processes.
(2) Impact resistance: Since the bottom plate of the blast furnace top wear-resistant lining plate is made of low-carbon steel with good plasticity, it can absorb energy during the impact process, so the blast furnace top wear-resistant lining plate has strong impact resistance and resistance. Crack resistance is suitable for working conditions with strong vibration and shock.
(3) Convenient operation: The wear-resistant lining plate of the blast furnace top can be made into standard-sized plates, which is simple, convenient and flexible to operate. Because the bottom plate is soft, it can be cold processed inward, and can be cut by heat sources such as plasma arc and carbon arc. It can be customized to be welded into shape, making on-site welding work time-saving and convenient.
(4) High cost performance: Considering the maintenance cost, the cost of replacing parts and the loss of downtime, the performance price of the parts of the blast furnace top wear-resistant lining plate making machine is two to three times that of ordinary materials.
Influence of blast furnace top pressure on ironmaking productionTime of issue : 2022- 04-20
Increasing blast furnace top pressure is one of the technical measures to optimize blast furnace operation.
At present, high furnaces with different volumes in our country generally increase the top pressure to obtain benefits. Blast furnace top gas pressure greater than 0.03 MPa is called high pressure operation. After changing from normal pressure to 80kPa high pressure, the blast volume can be increased by 10%-15%,

Spot inspection, lubrication and maintenance of main equipment on furnace top
1. What are the main equipment of the furnace top?
The furnace top equipment is mainly composed of airtight box, distribution chute, material tank, valve box, upper and lower dense, one level, two level, uniform release, cyclone dust removal, flap chute and other parts.
China's steel industry has entered the era of meager profitsTime of issue : 2022- 04-20
In 2012, China's steel industry faced not only development opportunities from structural adjustment, transformation and upgrading, but also severe challenges such as soaring costs, slowing demand growth, and the greatest pressure on energy conservation and emission reduction. China's steel industry has entered a meager profit era of "high cost and low profit", and it is expected that this meager profit operation will be difficult to change in the next two to three years.
