レを生じたりする。However, in the conventional device, the cooling water applied to the grindstone falls on the steel material to be cut, which increases the hardness of the steel material and causes a crack in the grinding.
また、砥石に対する不均一な水掛けは、砥石の摩耗度が
異なるいわゆる異形摩耗を生じて、切断端面の品質を損
なう原因となる等の問題点があった。Further, there is a problem in that uneven watering of the grindstone causes so-called irregular wear with different degrees of wear of the grindstone, which causes the quality of the cut end surface to be impaired.
「考案が解決しようとする課題」 本考案は、前記問題点を解決するためになされたもの

０℃程度の温度となっている。When a plurality of steel materials W are conveyed to the cutting position, indexed to a predetermined size and clamped by the clamp device 12, the reversible motor 3 for driving the carriage is driven to move the carriage 4 toward the cutting position. The grindstone drive motor 8 is driven to rotate the grindstone 11. When the grindstone 11 reaches the cutting position, the cylinder 6 is operated to swing the frame 7 supported by the shaft 5 of the carriage 4, and the front end portion of the frame 7, that is, the grindstone 1
1 is lowered and the carriage 4 is continuously moved to advance the grindstone 11 to cut the steel material W. The steel material W is rolled in the rolling process, fast-forwarded through the cooling floor, and conveyed to the cutting position.
The temperature is about 0 ° C.

す。With the start of rotation of the whetstone 11, inside the whetstone cover 21,
Cooling water is jetted from the jet outlet 31a of the nozzle 31 toward the side surface of the grindstone 11, adheres to the grindstone 11 to lower the temperature of the grindstone, and the cooling water bounced from the grindstone 11 is transmitted to the inner wall of the grindstone cover 21 and the drain plate 32. It falls into the cooling water recovery gutter 44.
Further, the water droplets of the cooling water passing through the water draining plates 32 on the air flow caused by the rotating grindstone 11 come into contact with the next water draining plates 33 and 34 and fall into the cooling water collecting trough 44. Further, a pressure air is blown from the air ejection port 35a of the air nozzle 35 to scatter and remove the cooling water adhering to the surface of the grindstone 11. The cooling water that has been scattered and removed travels along the inner wall of the grindstone cover 21 and falls into the cooling water recovery gutter 44. The recovered cooling water flows down to the drainage gutter 16 from the tip of the extension gutter 45 connected to the rear end of the cooling water recovery gutter 44. Drainage gutter 1
6 is attached to the rail 2 on which the carriage 4 of the hot grindstone cutting device 1 moves, and corresponds to the lower part of the extension gutter 45 of the grindstone cover 21 that moves as the carriage 4 moves, so that the collected cooling water leaks. Instead, it is drained to the drain pit 18. Since the recovered cooling water contains abrasive grains, a binder, chips, etc. that have been peeled off from the surface of the grindstone 11, the cleaning water is ejected from the cleaning water ejection nozzle 17 to the drain gutter 16 and washed off to the drainage pit 18. .

, The cooling water supply is cut off at the same time, but the pressurized air supply continues.
前記熱間砥石切断装置１の始動から切断終了までの一連
の作動は、シーケンス制御により自動的に行われる。A series of operations from the start of the hot grindstone cutting device 1 to the end of cutting are automatically performed by sequence control.

An air nozzle that removes the cooling water adhering to the draining plate and the grindstone is placed, and a cooling water recovery gutter that collects the cooling water that flows down the draining plate and the inner wall of the whetstone cover and drains it to the outside of the whetstone cover is placed below them. Therefore, not only both side surfaces of the grindstone are cooled uniformly, but also all the cooling water is collected. Therefore, it is possible to eliminate the conventional problems of spattering the steel material to be cut and increasing the hardness to cause grinding cracks, and impairing the quality of the cut end surface due to the irregular wear of the grindstone. Further, the uniform wear and uniform cooling of the grindstone prolongs the life of the grindstone, which contributes to the saving of running cost.
