In the following months I visited plants in Russian, England, West Germany, and East Germany. About a year after my return from Europe, I asked our workers in Chicago what output they achieved on this furnace. "Not 75,000 t per month," they answered. "Thatisnot an answer," I said and again asked, "What did you achieve?" "74,592 t in October," was the answer."

Describing the road of life of 1. P. Bardin, Academician A. N. Nesmeyanov said: "The road of Ivan Pavlovich isamazing and symboli~ from a peasant's farm to a scientist known throughout the world; from a worker, black- smith and machinist to one of the greatest metallurgists, to a leader of Soviet science. This was a remarkable cre- ative road."

His remarkable activity was recognized not only in the Soviet Union but also abroad. I. P. Bardin wasa mem- ber of the German Academy of Sciences in Berlin, the Hungarian, Rumanian, and Czechoslovakian Academies of Sciences, the American Institute of Ferrous Metallurgy, the American Railroad Society, the American Geographical Society, and other organizations. The Swedish Academy of Technical Sciences awarded him the gold medal of Brinell.

The Soviet government highly valued the services of I. P. Bardin. He was awarded the title of Hero of Social- ist Labor, he was the winner of the Lenin and State prizes, he was awarded seven Orders of Lenin, and medals. In 1934, he was elected a member of the All-Union Central Executive Committee of the USSR, and in 1937 was elected a Deputy of the Supreme Council of the USSR to all convocations.

The entire life of I. P. Bardin up to his very last minute was devoted to untiring labor, to "business," as he himself liked to say. Ivan Pavlovich died suddenly at the meeting of the Gosplan of the USSR while discussing prob- lems of the general plan for the development of ferrous metallurgy, after his address devoted to the questions of pre- paring iron ore for blast-furnace melting.

This death while working most fittingly corresponds to his entire life, devoted up to the end to service to his Motherland.

M e l t i n g W i t h o u t C o k e Generations of metallurgists have dreamed of cokeless blast-furnace melting. Already 9-15% of coke in blast-

furnace production has been replaced by natural gas. An increase in the blast temperature to 1200-1400"C will make it possible to save 40-50 kg of coke per ton in addition to the savings of 100 kg of coke per ton of pig iron already obtained at 1000*C. But the complete substitutionof natural gas for coke is possible only by initially heating it up to 1100"C. Blast-furnace melting in a cokeless furnace is possible at 1600-1700"C with incomplete combustion of natural gas. The design of such a furnace and the principles of the technology of the blast-furnace process on the furnace have already been worked out at the Donetsk Polytechnical Institute.

U l t r a s o n i c s , A M o n i t o r The laboratory of electroacoustics of the Leningrad Engineering Institute has created a unique device, UZIL-01,

for industrial ultrasonic monitoring of the quality of rolled sheet goods. The monitor automatically traces a defecto- gram, on which are designated the configuration and location of internal defects: seams, laps, etc. The device en- sures mass monitoring of products directly in the shop. The new instrument is already being successfully used at the

Nizhne-Tagil Metallurgical Combine.

C a p r o n in M e t a l l u r s y Capron (polycaprolactam resin and fiber) has many advantages over bronze, 1cad, steel, and other metals. It

is not oxidized, it has a low coefficient of friction, is oil and gasoline resistant, and does not conduct electricity.

Moreover, capron parts are manufactured by a more modern t e c h n o l o g y - b y the pressure casting method, they do

not require addi t ional t reatment , and are much cheaper than meta l parts. Capron parts have proved themselves in

operation. The Petrovskii Plant has already introduced into production 328 different capron parts weighing 3 g-

7.5 kg.

A K i l o m e t e r o f T u b i n ~ P e r H o u r A finished meta l tube appears from the open door of the truck. Within two or three hours, hundreds of meters

of vent i la t ion tubing lie on the platform.

The Ukrainian Scientif ic Research Tube Institute has worked out and created a device for the production of th in-wal led tubes with a spiral locking seam. The unit is mounted on a trai ler . It can work off an ordinary e l e c -

t r ica l network or from a portable e l ec t r i ca l power station with a gasoline engine. Such a machine can produce more than a k i lometer of tubing with a d iameter of 55 mm and up to 80 m of tubes with a d iameter of 820 mm per hour. Three men service the unit.

Chi l l ing is a progressive method of casting. Its distinguishing feature is the high rate of cooling the meta l .

The essence of chi l l ing is as follows: l iquid meta l is poured into a mold at tached to a rotat ing device. During the short t ime of holding, only a very small layer has t ime to become cool, " to be chil led, ~ on the surface of the mold,

the bulk of the me ta l is liquid, and on rotating is poured out. A casting r e m a i n s - a thin shell whose inside and out-

side configurations are determined by the shape of the model . Nonmeta l l ic inclusions and gas bubbles are driven

back from the crysta l l izat ion boundaries, do not enter the body of the casting, and do not form in it shrinkage porosity. The chi l l ing method is beginning to be used for the continuous casting of tubes.
