(2) Jangan mengganti stasiun pompa air pendingin selama bekerja.
(3) Amati dengan cermat balok berpendingin air selama peleburan dan setelah penyadapan. Jika ditemukan kebocoran air, segera hentikan peleburan, tekan untuk berhenti, dan jangan goyangkan tungku.

Kami membuat gulungan yang berbeda untuk baja strip panas, baja strip dingin, bagian, kawat dan tulangan juga gulungan untuk pipa tanpa sambungan. Jika ada kebutuhan, itu akan sangat dihargai!
(1) Before smelting, check that there is no water on the ground in the area.
(2) Regularly check the wall thickness of the furnace lining, the condition of the refractory materials on both sides of the oxygen lance and the furnace door.
(3) Repair the furnace in time according to the furnace repair plan.
Part 6: temperature measurement and sampling
Greater risk factors
Manual temperature measurement and sampling in front of the furnace, the furnace turning speed is too fast, the furnace turning operation is out of control, and the steel is poured out.
Types of accidents prone to occur
Other explosions, scorching.
Main preventive measures
(1) Manual temperature measurement and sampling to observe the pressure in the furnace to slowly pour the furnace.
(2) Manual temperature measurement and sampling stand on the side of the fire door, and wear protective clothing.
(3) Check before smelting that there is no water on the ground in the area.
Part 7: tapping
Greater risk factors
The molten steel tanker does not pour steel in the correct position, and there is water on the ground.
Types of accidents prone to occur
Other explosions.
Main preventive measures
(1) Check and confirm the tapping point of the molten steel tanker.
(2) Slowly shake the furnace.
Part 8:converter smelting
Greater risk factors
The slag tank is not in place, there is water or damp waste in the spilled slag tank.
Types of accidents prone to occur
Other explosions.
Main preventive measures
(1) Check that the slag tanker moves to the slag discharge position of the converter, and the alignment is accurate.
(2) Check that there is no water and moisture-free waste in the slag tank.
(3) Check and confirm that there is no water and moisture in the slag channel.
Part 9: slag splashing to protect the furnace
Greater risk factors
Nitrogen leaks.
Types of accidents prone to occur
Poisoning and suffocation.
Main preventive measures
(1) Check the valve position and joints of the nitrogen system for no leakage.
(2) Check that there are ventilation facilities in the nitrogen valve room and there is no leakage.
(3) Before entering the nitrogen and argon valve chambers for inspection, ventilate and check with an oxygen detector before entering.
It is necessary for take care of each details in steel making company.And wish every steel company with safety production!
We make different rolls for hot strip steel,cold strip steel,sections,wire and rebar also rolls for seamless pipe.If any need,it will be highly appreciated!
