Mould is the core equipment of continuous casting machine. It is the initial casting of molten steel to meet the requirements of the quality of the billet and the production of key equipment can be carried out smoothly.
Mould to undertake the molten steel injected from the tundish and make it according to the provisions of the section shape solidified into a solid shell.
It is the most critical part of the continuous casting machine, the structure, material and performance parameters plays a key role of the slab quality and casting machine production.
When pouring steel start, the head of the dummy bar is the movable insole of the mould. When the molten steel is poured into the mould, it gradually condenses to a certain thickness and is continuously drawn out. At this moment, the inner wall of the mould is subjected to the static pressure of molten steel and the blank The relative movement of the shell friction and other mechanical and thermal stress caused by the combined effect, its working conditions is extremely poor.
In order to obtain qualified billet, mould should meet the basic conditions
(1) with good thermal conductivity, so that the rapid condensation of molten steel forming.
(2) Good wear resistance, to extend the life of the mould, reduce maintenance workload and replace the mould time, improve the caster's operating rate.
(3) Adequate rigidity, especially in the case of chills and heat, with small temperature gradients.
(4) The structure is simple, compact, easy to manufacture, easy to assemble and disassemble, easy to adjust, and the cooling water channel can be connected by itself for quick replacement; the weight is small, so as to reduce the inertia force during mould vibration and reduce the driving power of the vibration, and the mould vibration smooth.
