Key points of lubrication for steel plant equipment

The lubrication conditions in the metallurgical industry are complex, and compared to other industries, the consumption of lubricants is high. Metallurgical equipment mainly includes sintering equipment, ironmaking, steelmaking and non-ferrous metallurgical equipment, and pressing equipment. The lubricating oil for steel production equipment has many special features, especially for large complete sets of equipment, which have a high degree of automation, need to withstand heavy loads with impact, high working temperature and high movement speed. Some outdoor operation equipment operates in harsh environmental conditions, with high dust, humidity, and easy corrosion. Therefore, there are high requirements for equipment lubrication and oil.

Wind Conveyor Description

Pneumatic conveying device is a transportation device that uses air energy to transport materials in a closed pipeline. It consists of a material entry mechanism, a material conveying pipeline, and a material discharge mechanism. Pneumatic conveying devices are divided into negative pressure conveying and positive pressure conveying according to the pressure formation method within the system; According to the mass concentration ratio of solid gas two-phase flow in the conveying pipeline, it can be divided into dilute phase pneumatic conveying and dense phase pneumatic conveying. Among them, dense phase pneumatic conveying can be divided into dense phase dynamic pressure and dense phase static pressure pneumatic conveying.

Preventive methods for reducing efficiency of bag filter

The good air permeability of dust removal bags is not achieved by increasing the aperture, but by reducing the aperture at the same time, rather than relying solely on the material's air permeability. The surface of the dust removal bag is smooth, the dust is not easy to stick, and the degree of epidemic prevention reaches a self-cleaning type, which is based on the understanding that the quality of the filter material itself cannot be improved. Any statement that emphasizes that the high filtration speed of the dust removal bag will threaten the life of the filter bag is at the cost of sacrificing the number of bags and increasing the volume of the dust collector. It can also increase the pores, which can form the advantage of low resistance. The current allowable filtration wind speed of the filter material in the dust removal bag is 1.2 meters per second, with low and approximately constant wind resistance, fewer cleaning times, and energy savings. The filtering wind speed is high, the filter bag has a long service life, and the material strength is high, toughness is good, wear resistance, and high temperature aging resistance.

Controlled cooling process for high-speed wire hard wire production

In the wire production industry, wire rods made of medium to high carbon steel with a carbon mass percentage of not less than 0.45% in high-quality carbon structural steel are commonly referred to as hard wires. Hard wire is a raw material used for processing low relaxation prestressed steel wire, steel wire rope, steel strand, tire steel wire, springs, etc. At present, domestic hard wire generally has problems such as low Soxhlet formation rate, poor plasticity, high strength, and surface defects, which seriously affect the first drawing performance. Therefore, studying how to develop reasonable cooling control processes in actual production, effectively controlling the quality and performance of hard wire products, has positive significance.
