THERE ARE UNTAPPED RESERVES L. N. Kutsentov The steel makers of the Cherepovets metallurgical plant are successfully filling the task set before metallurgists of our country by the party and government: to produce 100 million t of steel in 1967. The Komsomol-youth collective of the No. 3 open-hearth furnace, which bears the honored title of Fifteenth Congress of the Leninist Young Communist League of the Soviet Union, is successfully struggling for a further increase in the productivity of labor. Thus, during the months of 1967 that have passed, the average rate of a melt has increased by 15 t, waste has been cut in half, the consumption of the metallic charge has been reduced (by 4 kg) and of fuel (by 8 kg) per ton of steel produced. The main reason for the change of the qualitative indexes is the improvement in the technological regime of melting and pouring the metal. But the reserves for increasing the productivity of the furnaces have still not been fully exhausted, Thus, a device for the continuous measurement of the temperature of the furnace roof and the technology of using oxygen were recently mastered on our furnace. However, the open-hearth workers presently receive oxygen irregularly and not in a sufficient quantity (only 1000 m s per hour) which inhibits an increase of steel production. We are also mastering a device for the continuous measurement of the temperature of molten steel. Such de- vices are already being used successfully on four furnaces of our plant. A reduction of downtimes, which at present still amount to 12.8%, and an increase of roof life also help to increase the productivity of furnaces. Here the joint efforts of the steelmakers and repairmen are needed. In 1967 a school of advanced methods of production was held in the open-hearth shop. The collective of our plant used extensively the advanced experience of the steelmakers of other enterprises. Especially close contacts have been established between the collectives of our plant and Zaporozhstal'. We are competing with one another and learning from one another. Thus, the Zaporozh'e metallurgists have nicely worked out the operation of guniting the back wail of the furnace, which is done every month. We perform this operation as the occasion sees fit. On the basis of the experience of our Ukrainian friends, a belt machine was assembled at our plant for filling the sil!s, which reduced melting time by at least 20 min, freed the charging crane, and facilitated the work of the brigade. However, the machine has still not been mastered. With the use of all these reserves the productivity of labor and the quality of the metal produced can be raised even higher.

THERE ARE UNTAPPED RESERVES

L. N. K u t s e n t o v

The steel makers of the Cherepovets me ta l lu rg ica l plant are successfully f i l l ing the task set before me t a l l u rg - ists of our country by the party and government: to produce 100 mi l l ion t of s teel in 1967. The Komsomol-youth co l l ec t ive of the No. 3 open-hear th furnace, which bears the honored t i t le of Fifteenth Congress of the Leninist Young Communist League of the Soviet Union, is successfully struggling for a further increase in the productivi ty of labor. Thus, during the months of 1967 that have passed, the average rate of a me l t has increased by 15 t, waste has been cut in half, the consumption of the me ta l l i c charge has been reduced (by 4 kg) and of fuel (by 8 kg) per ton of

s teel produced. The main reason for the change of the qual i ta t ive indexes is the improvement in the technological reg ime of mel t ing and pouring the meta l .

But the reserves for increasing the productivi ty of the furnaces have sti l l not been fully exhausted, Thus, a dev ice for the continuous measurement of the temperature of the furnace roof and the technology of using oxygen were recent ly mastered on our furnace. However, the open-hear th workers presently rece ive oxygen irregularly and not in a sufficient quanti ty (only 1000 m s per hour) which inhibits an increase of steel production.

We are also mastering a device for the continuous measurement of the temperature of mol ten steel. Such d e - vices are a l ready being used successfully on four furnaces of our plant.

A reduction of downtimes, which at present s t i l l amount to 12.8%, and an increase of roof l i fe also help to increase the productivi ty of furnaces. Here the joint efforts of the s teelmakers and repairmen are needed.

In 1967 a school of advanced methods of production was held in the open-hear th shop. The co l lec t ive of our

plant used extensively the advanced experience of the s teelmakers of other enterprises. Especial ly close contacts have been established between the col lec t ives of our plant and Zaporozhsta l ' . We are compet ing with one another

and learning from one another. Thus, the Zaporozh 'e metal lurgists have n ice ly worked out the operat ion of guniting the back wail of the furnace, which is done every month. We perform this operation as the occasion sees fit. On the basis of the exper ience of our Ukrainian friends, a bel t machine was assembled at our plant for f i l l ing the sil!s, which reduced mel t ing t ime by at least 20 min, freed the charging crane, and faci l i ta ted the work of the brigade. However, the machine has stil l not been mastered.

With the use of al l these reserves the product ivi ty of labor and the quali ty of the me ta l produced can be raised even higher.
