RU46212U1 - UNIT CONTINUOUS CASTING MACHINE COOLING COOLER - Google Patents

Abstract

The utility model relates to mechanical equipment and can be most effectively used in rollers of a machine for continuous casting of workpieces. The technical problem solved by the utility model is to simplify the design of the device, ease of operation, increase reliability, uniform cooling of the rollers, which leads to a decrease in non-order products and increase production. The essence of the utility model is that a device including a water supply pipe located inside the roller cavity and a drain box is characterized in that a seal is installed at the end of the roller and a sleeve is installed on the water supply pipe, on which the spring is located, and the width the seal is equal to the inner width of the drain box, and its upper part is made with a recess for free drainage of water.

Description

The utility model relates to mechanical equipment and can be most effectively used in rollers of a continuous casting machine (CCM).

Known furnace roller with a cooled shaft, which includes a barrel with end sleeves, mounted on the shaft and a water block mounted inside the shaft and made in the form of a sleeve with external screw grooves, while the water supply tube is placed inside the node coaxially to the shaft and forms a cavity between the inner the surface of the water block and the outer surface of the tube (patent No. 2056027).

The disadvantage of the described design is the design complexity, possible clogging of the screw grooves with dirt, which can lead to emergency situations and violation of the cooling mode.

A device for cooling furnace rollers is known, comprising a pipe for supplying water located inside the cavity of the roller, a drain box and a funnel, the pipe being rigidly fixed in the journal of the roller and in the bore of the drain box by means of a glass with a set of rubber seals and a flange attached to it and a drain box located inside the funnel (patent No. 2179691)

The disadvantage of the design is its complexity, inconvenience in operation due to the frequent replacement of rubber seals, uneven cooling of the rollers.

The technical problem solved by the utility model is to simplify the design of the device, ease of operation, uniform cooling of the rollers, which ensures their reliable operation, reducing the number of repairs, increasing production and reducing non-demanding products.

The technical problem is solved in that the device for cooling the rollers of a continuous casting machine, including a water supply pipe located inside the roller cavity and a drain box, is characterized in that a seal is installed at the end of the roller, and a sleeve is installed on the water supply pipe, on which a spring is placed, and the width of the seal is equal to the inner width of the drain box, and its upper part is made with a recess for free drainage of water.

Such a structural embodiment of the device provides uniform cooling of the roller, because fasting, the incoming water begins to pour out of the cavity of the roller only after it is completely filled. The presence of a spring ensures the tightness of the structure, at the same time, in case of water pressure drops, the spring regulates the flow of water.

In addition, the implementation of the seal of the proposed form eliminates its rotation, which ensures that the recess for draining the water is always only in the upper position.

The essence of the utility model is illustrated by the drawing, where Fig. 1 shows a general view of the device (section), and Fig. 2 shows a section along AA.

The device contains a cooled roller 1. Inside the cavity of the roller 2 is a pipe 3 for supplying water. At the end of the roller there is a drain box 4 with a supply 5 and a discharge 6 pipes for supplying and discharging water. A seal 7 is installed to the end of the roller 1. A sleeve 8 is installed on the water supply pipe 3, on which a spring 9 is located, which presses on the seal 7 through the washer 10. The seal 7 has a width B equal to the width of the drain box, and the seal 7 has a recess on top 11, which forms a lumen 12 for free discharge of water.

The device operates as follows.

Cooling water is supplied to the inlet pipe 5, which passes through the pipe 3 and exits from it and washes and cools the internal cavity of the roller 1. The water does not pour out until the cavity 2 of the roller 1 is completely filled, after which the water begins to pour into the drain box 4 through the lumen 12 made using the recess 11 in the seal 7.

In case of increasing water pressure in the system, the spring 9 is squeezed out and the seal 7 releases the water flow.

As a result of using the proposed device in the oxygen-converter shop of OJSC MMK on a continuous casting machine, the reliability of the rollers and the cooling quality increased, which led to a decrease in non-order products and an increase in production.

Claims (1)
