Problems solved by technology

[0002] The existing continuous casting machine front-cut roller table water system piping is connected in series by each flow-cut roller. No matter which flow-cut roller is leaking, it is necessary to close the front-cut roller cooling. The main water valve, the maintenance operation efficiency is low, and the continuous casting must be shut down, resulting in production stagnation
In addition, frequent switching of the main cooling water valve will also accelerate damage and increase production costs

Embodiment Construction

[0010] Below, the present invention will be described in further detail in conjunction with the accompanying drawings.

[0011] Such as figure 1 As shown, a cooling system for the front-cutting roller table of a continuous casting machine is used to provide circulating cooling water to each roller 20 of the front-cutting roller table, and the said front-cutting roller table has a plurality of streams 30 arranged in parallel, Each of said streams 30 has the same number of said rollers 20 . The mode of this embodiment takes the actual production situation of a continuous casting workshop of a steelmaking plant as an example. The roller table before cutting has seven streams, and each stream has 15 rollers.

[0012] The cooling system includes water inlet main pipe 1, water inlet main valve 2 installed on water inlet main pipe 1, return water main pipe 3, return water main valve 4 installed on return water main pipe 3, water inlet main pipe 1 and return water main pipe 3 are ma...

Abstract

The invention discloses a continuous casting machine before-cutting roller way cooling system. According to the continuous casting machine before-cutting roller way cooling system, a water inlet totalpipe and a water returning total pipe are taken as a first-stage pipeline, second-stage pipelines extending in the horizontal direction perpendicular to a before-cutting roller way are led out from the first-stage pipeline, and third-stage pipelines are led out from the second-stage pipelines in the extension direction of flows, each third-stage pipeline leads out a plurality of sets of water inlet and outlet hoses to provide cooling water for one or two flows adjacent to the corresponding third-stage pipeline, and the third-stage pipelines are provided with control ball valves, when one roller leaks water, closing the control ball valve of the third-stage pipeline connected with the water inlet and outlet hose of the roller is just needed, water leakage can be disposed, the maintenance efficiency is effectively improved, the labor intensity of maintenance personnel is reduced, meanwhile, the cooling water is still supplied to the other flows, continued proceeding of production can bemaintained, so that production stagnation is avoided, in addition, the opening and closing times of a water inlet total valve and a water outlet total valve are reduced, the usage cycles of the waterinlet total valve and the water outlet total valve are effectively prolonged, and the production cost is lowered.

Description

technical field [0001] The invention relates to continuous casting machine equipment, in particular to a cooling system for a roller table before cutting of a continuous casting machine. Background technique [0002] Continuous casting machine front-cutting roller table The existing continuous casting machine front-cutting roller table water system piping is connected in series by each flow-cutting roller. No matter which flow-cutting front-roller is leaking, it is necessary to close the front-cutting roller table for cooling The main water valve, the maintenance operation efficiency is low, and the continuous casting must be shut down, resulting in production stagnation. In addition, frequent switching of the main cooling water valve will also accelerate damage and increase production costs. Contents of the invention [0003] Purpose of the invention: In order to overcome the defects of the prior art, the present invention provides a cooling system for the front-cut roll...
