A rolling production line temperature control device process equipment

Abstract

The invention discloses processing equipment of a temperature control device of a rolling production line. The processing equipment of the temperature control device of the rolling production line comprises a rolling mill I, a temperature control rack I and a rolling mill II, all of which are connected in sequence, wherein the output end of the rolling mill I is connected to the input end of the temperature control rack I; the output end of the temperature control rack I is connected to the input end of the rolling mill II. As the temperature control rack is arranged between the two rolling mills, online temperature efficient control on a large-scale rolled piece can be realized, a low-temperature rolled piece with uniform cross section can be obtained, temperature-controlled rolling is realized, and accordingly products with good mechanical performances are obtained. In addition, the processing equipment of the temperature control device of the rolling production line can realize continuous temperature-controlled rolling of the large-scale rolled piece without affecting production efficiency.

Description

technical field [0001] The invention belongs to the technical equipment field of a rolling production line, and in particular relates to a temperature control device technical equipment of a rolling production line. Background technique [0002] With the rapid development of industries such as machinery, automobiles, and military industries, the market demand for high-value-added large-scale bar products such as high-carbon steel, gear steel, alloy spring steel, and bearing steel is increasing. At the same time, the quality of large-scale bar products The requirements are increasing day by day. Because such products contain high content of C elements and alloy elements such as Cr, Ni, Mn, V, etc., in order to ensure product quality, high temperature heating is required when heating, and long-term heat preservation is required to fully dissolve C and alloy elements. Diffusion to eliminate or mitigate segregation. [0003] In order to ensure the good performance of the produ...

Problems solved by technology

[0005] For large-size rolled pieces, because of their large cross-section, it is difficult to quickly dissipate the heat of the core through the surface, and it is difficult to obtain low-temperature rolled pieces with a relatively uniform cross-section temperature in a short period of time for large-sized rolled pieces that have been heated at high temperature. Achieving temperature controlled rolling

[0006] In order to meet the temperature-controlled rolling requirements of large-size rolled pieces, some production lines have to keep the high-temperature rolled pieces on the input roller table in front of the rolling mill for a long time, and then roll them after the temperature of the rolled pieces drops to the required temperature. This method greatly reduces production line efficiency
