摘要： PURPOSE:To prevent an ingot from generating a camber after a cut of the ingot, by pressing vertical rolls against both side surfaces of an ingot, being cut lengthwise by a pair of upper and lower horizontal rolls having projections of V type sectional shapes on the outer peripheral surfaces of the rolls. CONSTITUTION:An ingot 7 conveyed by table rollers is guided by a front side guide 3 to intersect at right angles to the axial center line of horizontal rolls 1 to be bitten by the rolls 1. The distance delta between the peripheral tips of projections 2 of the rolls 1 is adjusted properly at every pass, e.g. the ingot 7 is cut lengthwise in hot state at the time of the 3rd pass. Though a camber of the ingot 7 is generated by this cut, the camber is corrected by pressing vertical rolls 4, being set at the intervals that enable the correction of the camber, against both the end surfaces of the ingot 7.

摘要： PURPOSE:To increase the charged of bloom per pit into a furnace, and to improve energy-economy and operation-efficiency by charging the blooms as they are in a multistage stacking state into a soaking pit in multi rows by a claw type-hanging device which is fixed to a pit-crane tongal. CONSTITUTION:The rows 12 of blooms 3 stacked in multistages accumulated on a pallet-table 11 in multi stages and multi rows in a bloom-yard, is lifted and transferred after said rows of blooms have been placed on the claw 8 of a claw type-hanging device. Then the rows 12 of said blooms are conveyed and brought down and charged into a soaking pit while keeping the distance between the furnace wall and the row of the bloom and the distance between each row of the blooms switably. When the rows 12 of the blooms has been supplied fully in accordance with the furnace capacity, another pallet table is placed on said blooms, and further, the rows of the stacked in multistage are charged by the same manner as described above on the upper surface of said blooms. Here, the numeral 6, 7 and 2a, 2b in the figure show respectively the grip for tongnes, the stationary beam and the pit ecane-tongnes.

摘要： PURPOSE: To reduce the transverse bending deformation produced during cutting and perform titled cutting surely by longitudinally cutting an ingot with bulges on the both side parts by means of a pair of cutting rolls while moving the same and applying screw-down on the both side parts.
CONSTITUTION: Both side parts of a slab 4 are formed with edgers or the like to form bulges 4a. Next, the slab 4 with said bulges 4a is screwed down at its central part during moving by the V-shaped cutting blades 3a of a pair of cutting rolls 3 until the spacing δ of both rolls 3 is made to a prescribed spacing, whereby it is longitudinally cut. At this time, both the side parts of the slab 4 are slightly screwed down by the bulged parts 3b of the rolls 3, and therefore inwardly bending cambers are generated in the screwed down parts of the slab 4. Hence, these cambers and the outward bending cambers generated at the cutting with the blades 3a are approximately offset, and the cambers of the cut slab are reduced.

摘要翻译：目的：减少切割过程中产生的横向弯曲变形，并通过一对切割辊在两侧部件上纵向切割具有凸起的铸锭，同时在两侧部件上进行螺纹切割。构成：板坯4的两个侧面部分都用切边机等形成凸起4a。接下来，在通过一对切割辊3的V形切割刀片3a移动期间，将具有所述凸起4a的板坯4在其中心部分拧紧，直到两个辊3的间隔三角形成规定的间距，由此纵向切割。此时，板坯4的两侧部分被轧辊3的凸出部分3b略微拧紧，因此在板坯4的拧紧部分中产生向内弯曲的弯曲部分。因此，这些弯曲部和外侧在与刀片3a的切割过程中产生的弯曲弯曲度大致偏移，并且切割的板坯的弯度减小。
