Abstract
The utility model discloses a steel rolling roughing mill condenser tube, include the L shape cooling branch who is set up by main pipe and main pipe both sides, the vertical part of cooling branch respectively to main pipe center slope, inclination is 6 degrees. The utility model discloses can more evenly cool off the roll tank bottom, effectively improve the steel volume of passing through of grooving.
Description
Technical Field
The utility model relates to a steel rolling roughing mill condenser tube.
Background
At present, a 540 short stress path rolling mill is generally adopted as a rough rolling mill of a continuous rolling production line in domestic bar and wire rods, the rotating speed of the rolling mill is low, the contact time between a billet and a roller is long, and the requirements on the pressure, the flow and the cooling effect of roller cooling water are high. The existing 540 short stress path rolling mill roller cooling water pipe is adopted, a water outlet is vertical to the surface of a roller, but because the roller has a groove, the vertical water pipe can not well spray cooling water to the bottom of the groove, and the defects of poor cooling effect at the bottom of the groove, overheating cracks and the like are caused. The production quality of the high-quality steel is influenced. The defects of large size fluctuation, hot top forging crack and the like occur.
Disclosure of Invention
An object of the utility model is to provide a steel rolling roughing mill condenser tube can cool off the roll groove bottom more evenly, effectively improves the groove steel passing capacity.
Solve above-mentioned problem the technical scheme of the utility model be, a steel rolling roughing mill condenser tube, include the L shape cooling branch that is set up by trunk pipe and trunk pipe both sides, the vertical part of cooling branch respectively to the trunk pipe center slope, inclination is 6 degrees.
The utility model discloses will former 540 rolling mill condenser tube remodels, the water pipe delivery port is perpendicular and the roll surface, adjusts to inside inclination 6, with groove pass turning inclined plane phase-match, and the roll cooling water can wholly cover the groove face, and the more former design cooling of roll tank bottom cooling is more even, effectively improves the groove steel passing amount. Through redesigning and using the cooling water pipe of the roller, the groove steel passing amount of the rough rolling 1#2# rolling mill of the unit is increased from 8000 tons to 10000 tons. The total unit consumption of the roller is reduced by 0.8 percent, accounting is carried out according to 30 ten thousand tons of output all the year around, and the total cost of the roller and turning is saved by 25 ten thousand yuan each year.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings.
Fig. 1 is a schematic view of the structure of the present invention;
FIG. 2 is a schematic side view of the present invention;
fig. 3 is a schematic diagram of the arrangement structure of the main pipe and the cooling branch pipe of the present invention.
Detailed Description
A cooling water pipe of a steel rolling roughing mill comprises a main pipe 1 and L-shaped cooling branch pipes 2 arranged on two sides of the main pipe, wherein vertical parts of the cooling branch pipes 2 incline to the center of a vertical surface of the main pipe 1 respectively, and the inclination angles are all 6 degrees, as shown in figures 1, 2 and 3. So that the roll groove bottom can be cooled better.
Claims (1)
1. The cooling water pipe of the steel rolling roughing mill comprises a main pipe and L-shaped cooling branch pipes arranged on two sides of the main pipe, and is characterized in that: the vertical parts of the cooling branch pipes are respectively inclined towards the center of the main pipe, and the inclination angles are all 6 degrees.
