VOL. 35, No. 10 (1956) ROSTER 125 Kaiser Dedicates Columbiana Plant

Kaiser Aluminum & Chemi­ cal Corp. dedicated its new basic refractories plant at Co­ lumbiana, Ohio, on September 29, marking an important milestone in the growth of its Chemicals Division. The affair became a com­ munity celebration as thou­ sands of local residents turned out for the plant tours con­ ducted during the morning and afternoon. Over 1500 pounds of beef were served at a public barbecue held at noon in Fire­ stone Park. Among company officials participating in the brief dedication ceremony which climaxed the day's activities were: E. W. Adams who will serve as plant manager at Administration building at the Columbiana operation. The plant building is in the background at the left. Columbiana; D. A. Rhoades, vice-president and general manager, Kaiser Aluminum & Chemical Corp.; and Frank make it possible to shorten delivery time in some cases by as M. Cashin, vice-president and manager of Kaiser's Chemi­ much as 14 days. cals Division. Periclase and chrome ore are the two raw materials used The Columbiana plant took 20 months to construct and in the basic refractories produced at the plant. Periclase is cost nearly $5 million. It covers more than three acres and supplied from Kaiser Chemicals Division's raw materials is located on a 185-acre site on the main line of the Pennsyl­ plants in California, while chrome ore is imported from the vania railroad and within a few miles of the Ohio-Pennsyl­ Philippine Islands. vania Turnpike. According to Mr. Cashin, the location will The plant has facilities for receiving and storing raw ma­ terials; grading, drying, classifying and mixing ingredients; pressing, drying and burning brick; checking and shipping The flrst pallet.load of basic refractory brick is pressed as operations begin finished products. Other facilities include an extensive labo­ at Kaiser's Columbiana plant. ratory for quality control, machine shop for servicing the plant, and a separate administration building. Kaiser first began making refractories in 1943 at a small plant in ~IiIpitas, Calif. These facilities, recently expanded and modernized, are now devoted to refractory research. After the war, a new refractory brick plant was constructed near its seawater plant at ~Ioss Landing. Both the Columbiana and ~Ioss Landing plants are in­ cluded in an additional $3 million expansion program planned by Kaiser. )iew equipment for ~Ioss Landing will double the present seawater handling capacity and will increase by 50% its capacity to produce periclase. New equipment at Columbiana will include additional pressing and materials handling facilities, which will increase the plant's capacity by 50%. When the installation is com­ pleted by the end of the year, the plant's annual capacity for basic brick, aside from ramming mixes and furnace grains, will be 48,000 tons. Intimately, the Columbiana plant will produce 110,000 tons of refractory products per year.
