Description

A machine is proposed for loading materials into the open-hearth furnace, with a conveyor feed of feed material with an endless belt, a trunk envelope, movably mounted on a trolley. The supply of trailing material to the conveyor belt is carried out by using suspended electric (hopper hoists or by an additional rear transporter.

FIG. I of the schematic drawing shows a side view of the machine for loading materials into the open-hearth furnace using a cooled ribbon; FIG. 2-; front view of an automatic filling machine with telefetra; FIG. 3 shows a side view; FIG. 4 is a scheme of supplying the stock from a warehouse to key points.

This machine consists of the main frame of the metal structure on which it is installed, an electric motor and a transmission for moving the whole machine along the rails along the furnaces. An endless band I c serves to feed the feed material into the furnace. coolant: frame and tub for cooling the circuit. The endless conveyor belt I is loaded with material using an additional (back) conveyor 4 or manually with shovels, and the human material is loaded with a rotating crane. Working tape I rounds the trunk 3, which is movable on the frame 5, mounted on the trolley 2. The trunk 3 can be rotated at an angle in the horizontal PLANE, rotating on the axis in its rear part. For the movement of the carriage 2 with the trunk 3 and for driving the movement of the endless conveyor belt I, there is a worm gear with an electric one. motor and clutches included (Fig. 1).

The machine is controlled on the main frame, but it can also be placed on the moving frame of the rev 3.

- When using electric suspension for supplying cages to the conveyor belt of the charging machine moving along the furnaces along the track 14 (Fig. 2), the charge material enters the hopper 13 of the feeder 16 from the box-bucket 17 supplied by the hoist 15, which moves along the mono-rail suspended path §, fortified to column 8 of the building. The feeder 16, driven by the electric motor 7, transmits in turn the charge material to the charging machine by means of the conveyor belt I (Fig. 2 and 3).

When filling the proposed device materials into the open-hearth furnace, several hoists 15 will be required,

depending on the size of the open-hearth shop. In order to avoid collisions of telphers 15, a blocking system 18 can be introduced so that the subsequent telfer, not income for a predetermined distance, to the first hoist, automatically stops (Fig. 2 and 3).

When loading material into the open-hearth furnace, hoists do the shortest way. For the safe exit of the hoist, an interlock 11 may be introduced into the open arrow. Material is supplied from the warehouse to the anchor points via air route 10 (Fig. 4).

The subject of the invention.

1. A machine for loading materials into an open-hearth furnace, characterized in that

that for feeding the feed material serves a cooled endless belt 1, an envelope movable along the frame 5 on the trolley 2 and a trunk 3 pivoting in the horizontal plane.

2. At the machine specified in clause 1 for feeding the material, on the belt 1 a belt conveyor 4.

3.When the car on. p. 1 application for feeding the material on the tape 1. feeder 16 with a hopper 13 filled with hoists 15..
