How does the lining ejection mechanism of induction melting furnace work?

The main components of the lining push-out mechanism are:

A Launch the cylinder

B Hydraulic valve and connecting pipe

C Furnace bottom joint that matches the system

The system operation is as follows:

Once the furnace lining cools down to 400°C, the furnace is turned 90 degrees, the oil cylinder is lifted with a crane, and the oil cylinder is connected to the furnace bottom. The oil pipe is connected to the control valve oil pipe by a quick connection method, the hydraulic pump station is started, and the furnace lining is pushed out.
