For saving of refractory and elevation of productivity about an arc furnace, technical improvement and enlargement of WCP have been pushed up to now.(1) About 70% of furnace wall and furnace cover of 70ton arc furnace installed at Daido Steels Chita Plant have been water cooled and this contributes to reduction of cost for refractory and elevation of productivity.(2) As a countermeasure of life elevation of WCP there was obtained a guide to extend the life of WCP after investigation of the influence of flow speed of cooling water and material quality upon burn-out thermal load together with clarification of damage cause due to structure of WCP and thermal stress.(3) After investigating the superiority of copper-made WCP an intention of putting a 70ton UHP furnace into a practical use was made. A layout for excellent control of preliminary parts that can be used together with four 70ton arc furnaces was materialized making the shape simplified and arranging coppermade WCP and steel plate made WCP at the bottom part and top part of the furnace wall respectively.
