High-pressure operation method of sintering process

Abstract

The invention relates to a high-pressure operation method of a sintering process, which is characterized in that each trolley on a sintering machine is continuously operated on a chain wheel drive device of a head wheel of the sintering machine, after a sintering material bed is ignited, multi-point continuous high-pressure blast is carried out, the multi-point continuous high-pressure blast is located on an igniter, the sintering machine adopts multiple air outlet pipes of an air bag, the air outlet pipes and an operation direction of the sintering machine are linearly uniformly distributed in a balanced manner, a positive pressures state is formed in the range, and the multi-point continuous high-pressure blast is realized; along the operation direction of the trolley, the multi-point continuous high-pressure blast is at a distance of 500 mm from the edge of an insulation cover, is at a horizontal distance of 700 mm from a breast board of the trolley, and is at a distance from any position at the left side and the right side of a central line, and the outlet of a multi-point high-pressure blast pipe is at a distance of 200-300 mm from a material surface at a height of the material surface of the breast board of the trolley. According to the high-pressure operation method of the sintering process provided by the invention, the problem of difficulty in popularization and application of the high-pressure operation can be overcome, the high-pressure operation method is very easy to implement in the sintering process, the scale of construction of a newly built sintering factory is reduced, and a large amount of raw materials and device operation cost are saved.

Description

technical field

[0001] The invention relates to a sintering process in the metallurgical industry, in particular to a high-pressure operation method for the sintering process. Background technique

[0002] At present, in the domestic metallurgical industry, the basic law of pressure and air volume changes in the traditional sintering bed along the sintering machine running direction is common in the actual production of belt sintering machines, and the regularity is strong. This traditional sintering process restricts the development of the industry. There are problems such as wasting a large amount of investment, wasting a large amount of basic materials, and wasting a large amount of power resources. Contents of the invention

[0003] The present invention overcomes the above existing defects, and aims to provide a high-pressure operation method for a sintering process.
