Tension leveler for continuous caster

Abstract

The embodiment of the invention discloses a tension leveler for a continuous caster, which comprises a first upright post, a second upright post, a third upright post, a fourth upright post and functional components. The functional components are arranged in a rectangular space enclosed by four upright posts; communicating pipes are arranged in the four upright posts respectively and communicated with one another; the first upright post is provided with a main water inlet; the third upright post is provided with a main water return port; the first upright post and the second upright post are provided with a plurality of water intakes; the third upright post and the fourth upright post are provided with a plurality of water outlets; and the water intakes and the water outlets are communicated with the components through water pipes. The water inlet and the water return port are directly arranged on a water inlet upright post and a water return upright post, so water inlet and water return drift diameters are increased, cooling water flow rate is increased, and the mobility of cooling water is accelerated. The functional components are directly connected with the water inlet upright post and the water return upright post through the water pipes, so the flow rates of water flowing through the function components are ensured, the problem of non-uniform cooling caused by the lowered back end water pressure is solved, and a fault point is easy to check when the device fails.

Description

technical field [0001] The invention relates to the field of iron and steel casting, in particular to a tension leveler for continuous casting machines. Background technique [0002] In the field of iron and steel smelting, continuous casting machines are used to cast molten iron and steel from blast furnaces into fixed shapes. The pouring mechanism of the continuous casting machine pours the molten steel into the crystallizer. Under the joint action of the crystallizer, the sector section and the secondary cooling section, the molten steel is solidified from a liquid state into a billet with a fixed shape. Under the action of straightening, a slab that meets the requirements is formed. The hot billet keeps the tension leveler in a high temperature environment all the time. To ensure the normal operation of the tension leveler, it is necessary to cool the functional components in the tension leveler. [0003] see Figure 1 to Figure 3 , the existing tension leveling machin...

AI Technical Summary

Problems solved by technology

[0005] In the existing tension leveling machine device, the main water inlet and return ports are set on the main water inlet and return pipes, the diameter of the main water inlet and return pipes is limited, the amount of water flowing into the water distribution device is limited, the fluidity of the cooling water is weak, and the cooling effect on the functional components is not good. it is good

All the water inlets are set on the main water inlet pipe, because the front and rear of the installation positions are different, and the water pressure is different, so that the front parts can still be cooled, and the water pressure of the rear parts is obviously reduced or even without water cooling. Uneven cooling of parts

[0006] The structure of the stainless steel water-cooled piping is complicated when connected inside the device, and it is difficult to find the fault point

In order to reduce leakage points, each pipe adopts welded elbows and tees, which brings inconvenience to maintenance

[0007] see Figure 5 , Image 6 , the stainless steel main water inlet and return pipes are located outside the tension leveler. In order to ensure that the external water pipes do not collide, it is necessary to increase the distance between the body of the tension leveler, which increases the difficulty of lifting
