SU391908A1 - DEVICE FOR SUPPLYING OF DISPERSE AGENTS TO STEEL-BURNING BUCKET - Google Patents

Description

II

The invention relates to ferrous metallurgy and is intended for use in open-hearth and converter shops.

Lift the device for the supply of ferroalloys in the steel-teeming ladle, consisting of a receiving hopper, chute, funnel with a vibrator, weighing dispenser and a belt transformer.

However, in the known device, the supply system deoxidizing intermittent; separately, not in a stream, loading into the bunker from the cars, reloading and weighing, transportation to the place of delivery of deoxidizers; The possibility of automating the process of creating a flow system is excluded.

The purpose of the invention is to automate the process and increase the weighing accuracy of deoxidizers.

This is achieved by the fact that the device is equipped with weight trolleys, furnaces for calcination, located under the receiving bins, connected to heat with the dispensing bunker through heat meters.

FIG. I depicts the described device, a general view; in fig. 2 is a section along L-A in FIG. one.

The operation of the described device is carried out as follows.

The deoxidizers from the warehouse are conveyed by the conveyor system to the mark of the shop where the conveyors are located /, they are unloaded, and discharging self-propelled trolleys 2 located on the conveyors load deoxidizers depending on their type into one or another bunker 3. Depending on the pulses of the level sensors of the silos comes to fill in a particular bunker,

Subscribe by quality composition. The operator, having received data on the needs of the species and the number of ferroalloys, sets the program on the remote control and turns on the deoxidizing system. By this command, the weighing carriages 4 are put into the bunker with the deoxidizing agents required for this melting and through the feeders 5 are filled with the necessary portion. The weighed portion through the funnel 6 is fed into the furnace 7 for firing up to 500-900 ° C,

or, their minimization (in case of repairs, malfunctions, etc.) is fed through the funnel 8 of the pipeline 9 directly to the transfer bunker 10. After receiving the data of the smelting analysis, the operator

remote control sets the task for corrective weighers //, after which the deoxidizers are given from the furnaces 7 through the receiving chutes / 2 to the weighing doser 11. Then the corrected portion

The feeder 13 is fed into the dispensing bin 10 with the help of the chute 14. The deoxidizers are sent to the chute 16 and through the gate 17 to the pipeline 18 with the help of the gate 15, and from it to the bucket 19. The capacity of the feeder is controlled by the drive 20, which allows in the required proportion and in the required time intervals.

Thus, the whole process of supplying deoxidizers, as well as other necessary additives (coke, fine lime, etc.), is transferred to an automatic in-line mode, allowing the use of electronic computers.

Subject invention

A device for feeding deoxidizers to a casting ladle consisting of receiving

hoppers with feeders, funnels, chutes, weighing batcher, characterized in that, in order to automate the process and increase the weighing accuracy of the deoxidizers, it is equipped with

bunkers on each floor of the weight trolleys, furnaces for calcination, connected by chutes through weighing batchers with a dispensing bunker.
