Description

one

The invention relates to metal tenlove treatment, in particular, to equipment for heating billets before rolling.

A known high-temperature sectional furnace for heating billets, comprising sections located one side other, with burners mounted on one side of the section, and a mechanism for transporting the workpieces.

The aim of the invention is to reduce fuel consumption for metal heating, increase the productivity of sectional furnaces and create favorable conditions for the implementation of heat recovery.

Supplied: 1a; spruce is reached by using preheating the metal of the heat of the leaving gas; from the main workings Kci .-. Ep, in which the billets are heated to a predetermined temperature, and so on ;; less than 1) and the previous one , gigolipypogo in the form of tables with expansion, 1; 1; 1 11 in 1 in iri rollers, rollers, IMSYu1 IMP possible vertical 1) ON: About displacement.

The invention is illustrated in the drawings, where in FIG. 1 shows a longitudinal section of the worker; x Kymer furnace; in fig. 2 is a section along A-A in FIG. one; In FIG. 3 is a section along BB in FIG. one; and FIG. 4 shows a section along BB in FIG. one; in fig. 5 - diagram of the table mechanism

for transferring blanks from one Russ to another.

The furnace contains the main working chamber /, the burner 2, the upper chamber 3, open in the arch 4, tables 5 with drive rollers. 6, upper row of rollers 7, middle row of rollers 8, lower row of rollers P, landing window 10 , cantilever rollers And, dispensing window 12, frame 13, guides M, reversible motors

15, blocks 16 and counterweights 17.

The heated blanks 18 move through the furnace in a zigzag manner along three Rusa, one above the other, for which there are three rows of rollers in the furnace - the upper 7, the middle S and the lower 9.

The blanks 18 through the landing window 10 enter the rollers 7 of the upper row and move to the exit of the furnace, hit the rollers // of the moving table. After loading the table with blanks 18, the rotation of the rollers // is stopped, and the table is lowered to the level of the middle row of rollers 8. After that, the rollers are rotated and the blanks 18 lying on them are transferred with great speed

the middle tier rollers 8, then the table rises after the next batch of blanks.

The blanks transferred to the middle Russian are moving along the 8 s directional rollers, in the opposite direction, where they are transmitted in a similar manner by the lower row of the rollers 9. At the end of the furnace

on the lower russa there is a dispensing chamber with cantilever rollers 11 placed in it, with the help of which the blanks 18 can be discharged from the oven from each rus separately, through the dispensing window 12.

The table 5 is also a frame 13, which does not move vertically in the special rails 14.

On paiMe 13 there is a drive reversing motor 15 cantilever rollers //.

To reduce the power consumption for moving the tables, they are suspended on chain or rope blocks 16 and are unloaded with counterweights 17.

Subject invention

Sectional furnace for heating billets containing chambers located one above

another with burners installed on one side of the chambers, and with a mechanism for transporting billets, characterized in that, in order to reduce fuel consumption for heating billets and increase productivity, the furnace is equipped with advanced transfer mechanisms made in the form of tables with on them drive rollers having the possibility of vertical movement.
