I’m sending you an updated drawing of the refractories for KL-710 and KL-711.It has been added some details for the refractory of the casting flange and an optimization of the thickness of the of the insulating layer of the refractory brick. This solution is a less expensive one and permits at the same time to increase the capacity of the two furnaces. If you don’t have placed the order yet or you can in case change it, we strongly recommend this solution.
