Abstract

This invention relates to ferrous metallurgy, in particular, to after-furnace treatment of steel in ladles. The aim of the invention is to increase the reliability of sampling and temperature measurement, reduce the duration of operations and improve working conditions. The device contains a guide in which the carriage moves with a fixed boom with a tip, a drive for moving the carriage, a slag punch that is bent in the lower part on the side of the thermoblock and is located under it, the middle part is hinged on the movable carriage, and at the top is provided with a roller interacting with a copier fixedly mounted on the guide, which provides the slag punch with a vertical position in the lower operating state relative to the axis of the thermoblock or a deviated position from the axis of the thermoblock eye inoperative upper position. The device is made with a waste thermoblock puller mounted on a rail with the possibility of swinging in a vertical plane. The puller is made in the form of a gutter open to the side of the thermoblock, and at the top there is a tooth-abutment with a longitudinal notch located symmetrically relative to the axis of the thermoblock. The swing plane of the puller coincides with the axis of the thermoblock and the puller is kinematically connected with a pivoting lever that interacts with the control ruler attached to the carriage. 2 hp f-ly. 5 il.

Description

The device for sampling and temperature measurement consists of a guide 1 in which the carriage 2 moves with the rod 3 fixed in it with the tip 4, the drive 5 moves the carriage 2, the slag punch 6 hinged to the carriage 2. In the upper part the slag plow 6 is provided with a roller 7, moving along the copier 8, which is stationary, fixed on the guide 1, the device also consists of a puller 10 for the spent thermoblock 9,. The puller 10 is hinged on the guide 1 with the possibility of swinging in a vertical plane, coinciding tayuschey with the axis of the fuser 9, in the upper part of the puller 10 fixed stop 11 with a longitudinal notch 12.

The puller 10 is kinematically connected with a puller 13 with a pivoting lever 14 fixed on guide 1, the lever 14 interacts with the control ruler 15 fixed on the carriage 2.

The device is placed on the platform 16 with a hole 17, under which is bucket 18 with slag 19 and metal 20.

The device works as follows.

In the initial position, the carriage 2 with the rod 3 and the tip 4 is in its extreme upper position. Slag punch 6 is deflected from the axis of the tip 4 to the side, while the curved part of the slag punch 6 does not coincide with the axis of the tip 4,

The ruler 15 is located above the pivot arm 14, which is rotated clockwise, and its left end is raised upwards.

The right end of the lever 14 through the puller 13 turns the puller 10 towards the side of the rod 3, while the longitudinal notch 12 coincides with the axis of the rod 3, and the lower part of the puller 10 closes the hole 17 in the platform 16, thereby shielding the mechanisms and maintenance personnel from radiation and emissions of liquid metal 20 from bucket 18.

When measuring the temperature or taking a metal sample, the worker-operator puts the thermoblock (or sampler) 9 manually on the tip 4 and turns on the actuator 5 on the lowering of the carriage 2, while moving downwards, the control line 15 fixed on the carriage 2 presses the left the end of the pivot arm 14, and the kinematically associated puller 10 deflects to the right, takes up a vertical position, and frees the path of the thermoblock 9 with the slag punch 6, opening the hole 17 in the pad 16.

The roller 7 of the slag punch 6, moving along the copier 8, on the curvilinear section of the latter rotates the slag punch 6 and aligns its curved part with the axis of the thermal block 9.

The size and between the upper part of the curved end of the slag punch 6 and the end of the thermal block 9 must be at least 180 mm.

Then the slag punch 6 punches the slag 19 and enters the metal 20. Behind it, the thermoblock (sampler) 9, the passage through the hole in the slag 19, also enters the metal 20 and the drive 5 is automatically switched off. The temperature is measured or a sample of metal 20 is taken. After a few seconds (L-7), the actuator 5 automatically turns on and the thermoblock 9 is removed from the bucket 18 and rises up, while the roller 7 of the slag punch 6 moves along the copier 8 and in a curved section of the latter the slag punch 6 from the axis of the thermoblock 9, with the control ruler 15 pressing down on the pivot arm 14 and the puller 10 turning to the left, towards the thermal block 9, covering it, and the cutout 12 of the tooth 11 of the puller 10 grabs the bar 3 and further movement of the carriage 2 at the upper end of the thermal block 9 rests on the tooth-stop 11, the carriage 2 with the holder and the tip 4 goes up, and the thermal block 9 remains in the groove of the puller 10 and slides away from the hole 17 to the platform 16.

In the upper position of the mechanism, the actuator 5 is automatically switched off and the carriage 2 stops, the mechanism remains in the initial position until the next cycle a. i

Technical and economic advantages are due to the fact that the device is more reliable in operation compared to the known solutions, is simple in design and safe to maintain, has small dimensions in terms of, and easily fits into the overall layout of the equipment of the secondary station.
