As the density of the molten steel is greater than the density of the steel slag, all the liquid steel is in the bottom of the slag tank, and the slag cans are usually placed for more than 48 hours before the cooling can be poured into the indoor cooling field to stir and produce the slag. The slag can be mixed with steel slag. , So the bottom of the molten steel in the cooling process solidified into a stainless steel cold steel firmly adhered to the bottom of the slag tank.
At present, the slag tank internal adhesion of stainless steel cold steel treatment often take Jet-lance oxygen cutting. Oxygen lance cleanup requires a longer operating time and higher energy costs, resulting in energy waste. Cold steel cutting process will occur in the slag tank was blown through the surface uneven uneven problem, oxygen cutting process produces a lot of dust affect the surrounding environment. In addition, the slag tank needs to be repaired after the cold steel cuts, causes the slag pot not to be able to throw in the continuous cycle utilization, the operating efficiency is low.
The new process is slag tank stainless steel cold steel picking technology, the use of "slag - clean - vibration - the whole take" process. The recovered cold steel is transferred to the cold steel cutting field, and is cut by an automatic cutting machine. The cold steel after cutting is returned to the steel making factory for reutilization.
specific process:
1, after cooling down the steel slag pouring out in the cooling field, there will be residual cold steel adhesion in the bottom of the slag tank, the use of crusher for stainless steel cold steel to the initial crushing vibration, making cold steel and slag tank can have a slight loosening . The use of lifting equipment will be placed on top of the beam to the slag tank, the operating personnel to enter the slag tank internal welding rod, rod welding the bottom of the four ribs. After welding, install the upper steel plate and hydraulic jack, connect the hydraulic hose to the hydraulic jack and manual hydraulic pump.
2, manual hydraulic pump to play the hydraulic jack to jack so there is a preliminary with the pressure, check the jack is in a vertical state, whether the interface of the hydraulic pipe leakage. Confirm the preparatory work is completed, the operator evacuated to a safe area, manual pressure to the hydraulic pump closed and observe the manual hydraulic pump pressure and hydraulic pipe connections, the general pressure to about 20MPa can pull out of cold steel from the slag tank , To be removed after the cold steel lifting equipment, the entire work is completed, the last remaining cold steel slag tank to clean up, repair, grinding, delivery.
Slag tank stainless steel cold steel picking technology, can make the metal recovery rate of 95% or more, improve work efficiency and extend the service life of more than 1.5-2 times the slag. The technology has the advantages of convenient operation, low running cost, high recovery rate of cold steel, and has high promotion value.
