Description

one

This invention relates to metallurgy, specifically to the continuous casting of metals.

An intermediate razvpvochny device for distributing metal into two molds is known, containing a two-glass funnel, a pedestal mounted on a shaft, and mechanisms for the manual and automatic control of the inclination of the funnel 1.

However, the known device does not provide a quick transition from automatic control to manual, and vice versa, and also does not provide an adjustment of the automation system during casting.

The aim of the invention is to simplify the conditions of service and to provide adjustment of automation in the casting process.

This is achieved by the fact that the device is equipped with a friction clutch and an eccentric, and a hinge pedestal is mounted on the shaft, the friction clutch being designed as a cup, one part of which is rigidly connected to the pedestal, and the other part covers the shaft and is split.

FIG. 1 shows the proposed intermediate filling device for the continuous casting of metals, general view; in fig. 2 is a section A-L in FIG. one.

Intermediate filling device contains dvuhstakannuyu funnel 1, pedestal 2, pivotally mounted on the shaft 3.

The shaft 3 through a system of levers 4 is rigidly connected to an automatic control mechanism, which is made in the form of a hydraulic cylinder 5 connected with an automation system. The manual control mechanism is made in the form of a lever 6 and is connected to a pedestal.

Pedestal 2 is fixed on the shaft in any position by means of a firing clutch made in the form of a cup 7, one part of which is rigidly connected to the pedestal, and the other part covers the shaft 3 and is split. A portion of the cup 7 is clamped on the shaft 3 with the help of an eccentric 8.

The operation of the device is carried out in the following manner.

When the casting device is operating in manual mode, the eccentric 8 is moved to the position where the glass 7 releases the shaft 3, thereby the pedestal 2 is disconnected from the shaft 3.

The metal is poured into the molds through the funnel 1, and its constant constant level in the molds is maintained by the pouring operator by

The slope of the pedestal 2 with the funnel 1 in the direction of one or another mold with the help of the lever 6 of the manual control. The level is monitored visually.

If it is necessary to switch from manual mode to automatic eccentric 8, they are transferred to the clamping position of the split part of glass 7 on shaft 3, and the process of maintaining the same metal level in both crystallizers is already carried out using the automatic control mechanism of inclination of the funnel 1.

This embodiment of the tundish provides a quick and healthy transition from automatic control of the tilt of the funnel to manual control and back even during casting, since the transition to manual control is carried out by simply separating the pedestal and the shaft, and the transition from manual pa is automatic by fixing

pedestal on the shaft with an appropriate adjustment of the source data for the automation system.
