The main task of the continuous casting operation area is making molten steel into qualified slabs. The indispensable thing is cooling water. Whether the cooling water can be used correctly is related to the continuous casting machine breakout accident and the quality control of the slab.
The engineer operated the following points：
In order to find a nozzle that more satisfies the speed-up requirements, comprehensive consideration is given to the spray angle, such as atomization effect, and water flow.
In order to solve the slab shrinkage defect at high drawing speed, a row of weak cold full water nozzles was used cleverly to stabilize the quality of the slab.
Introduce large-aperture slider: increase the drawing speed and shorten the pouring cycle
Promote the improvement of slag truck equipment: the time of removing steel slag is reduced from 45-50 seconds to 40 seconds
Lengthen the track and coordination plate of the torch cutting machine: prevent the billet from being cut
Rotary table rotation cycle reduction: 10 seconds
Reduce turntable rotation time: 18 minutes per day
