ABSTRAO-.e; Recent investigations (rof 1 to 3) indicated
that on
bottom pouring of steel at a velocity at which the top
zurface of tile motal in tile mould is free from crust",
an improvement in quality of the upper part of ingots
is obtained. In tile present paper an investigation of
tile influence of t1u.- velocity of tewing on the qw1lity
of the inGots is describ,~,d. Steels: carbon 10-50,
18y,hGT, 35YhGSA, 20RTGSA~ 20Kh-401Qi9 12EW13-30MI113,
smelted in 40 ton furnaces and bottom poured into 3 ton
in6ots were used for tile investigation. The velocity of
toeming was rontrollcd by vv,~-jiriS the nozzle3 in the

that an increase in the teemin(; rate by 2 to 2,5 times

inclusions. However, with increasing teeming velocity
the number of cra'-ks on th(A, in6cts shai-ply increases.
The formation of hot cracks depands, to a large extent
on the metal teMpOrature and its chemical composition
(Fig 2). In order t3 decrease the proportion of ingots

TITLE: Now Method for the Production of Prints of the
Macrostructure

ABSTRACT: A now nothod for the production of prints of the
macrostructure
without distortions is suggested, A printing color is applJed
to the templet, and the print is then applied to the paper
(Fig 1). The print may be made with the hands or a machine* In
the case of larger dimensions the latter process is more fa-
vorable as maohine-made prints are qualitatively better* The
taking of prints from polished and not cut templets leads to
a deterioration of quality (Fig 2). For the purpose of taking
prints of larger dimensions (700 x 920 mm) a platen machine of
the type DS? turned out to bo most favorable* There are 2 fig-
