Description

Technical Field

[0001] The utility model relates to the field of metallurgy, in particular to a stable structure of a split rolling inlet guide. Background Art

[0002] In the rod and wire workshop of the metallurgical industry, inlet guides are generally divided into sliding inlet guides and rolling inlet guides. At present, due to the improvement of the quality of various steels in the production process, the accuracy of sliding inlet guides cannot meet the needs of high-quality steel production, and rolling inlet guides are mostly used.

[0003] For example, the existing patent publication number CN204018387U is an integrated adjustable rolling guide for wire rod rolling mills. Since the guide body of this patent is integrated, when the guide body is repaired or maintained, the guide body needs to be sorted and disassembled to enable employees to repair or maintain the guide body. However, it is time-consuming and labor-intensive to sort, disassemble and install the guide body, which easily prolongs the repair and maintenance cycle and affects the use of imported guides. Although there are guide bodies divided into two interconnected half-box bodies on the market, the two interconnected half-box guide bodies are not stable when installed on one side of the rolling mill. They are prone to deviation, resulting in distortion and skewness of the internal rolled pieces, causing the rolled pieces to impact the guide rollers and bearings, thereby reducing the service life of the guides.
