Siphon type dewatering wiper for hot plate blank

Abstract

The invention relates to a siphon type dewatering wiper for a hot plate blank, and belongs to the technical field of hot rolling equipment in the metallurgical industry. According to the technical scheme, the siphon type dewatering wiper comprises a fixing support (1), hoisting connecting rods (3), siphon dewatering rollers (4), water collecting tanks (5) and a hot rolling conveying roller way (6), wherein the multiple siphon dewatering rollers (4) arranged side by side are arranged above the hot rolling conveying roller way (6) in the running direction of the hot plate blank, the two ends ofthe siphon dewatering rollers (4) are rotationally connected to the fixing support (1) through hoisting connecting rods (3), the water collecting tanks (5) are arranged below the two ends of the siphon dewatering rollers (4), the roller bodies of the siphon dewatering rollers (4) are concave roller with the thin middles and the two thick ends, a plurality of identical grooves (9) are engraved in the surface of the roller bodies in the axial direction, and each groove (9) is of a structure with the narrow middle and the two wide ends. The siphon type dewatering wiper has the beneficial effectsthat residual water on the surface of the hot plate blank passing through a dephosphorization machine or a rolling mill can be effectively and rapidly removed, the temperature difference between the upper portion and the lower portion of the hot plate blank is reduced, and head warping or buckling of the hot plate blank is prevented.

Description

technical field [0001] The invention relates to a hot slab siphon type dewatering wiper, which belongs to the technical field of hot rolling equipment in the metallurgical industry. Background technique [0002] During the hot rolling process of slabs, warping or buckling of hot-rolled slabs often occurs, which can easily cause product quality problems or production accidents. It can be known from the research that the large temperature difference between the upper and lower surfaces of the slab is an important reason for the phenomenon of head warping or buckling. An important reason for the large temperature difference between the upper and lower surfaces is that after the slab passes through the dephosphorization machine or rolling mill, there is a large amount of descaling water or roll cooling water remaining on the surface. Although this water will be evaporated quickly by the hot slab, it will There is also a lot of heat. This will not only cause a significant tempe...

AI Technical Summary

Problems solved by technology

This will not only cause a significant temperature drop of the slab, resulting in energy waste, but also aggravate the temperature difference between the upper and lower surfaces, making the temperature change of the slab more uncontrollable, resulting in problems such as head warping or buckling during the rolling process
